A vertical injection table is also used to make molds by compressing materials into a mold. At the same time, a vertical injection table is used to make molds, compressing, and compressing molds. The vertical injection table is also used to make molds, compressing, and compressing materials. Compressing molds are also used to make molds.

These vertical injection machines are large enough to require substantial amounts of water to be heated and injected into the mold directly. A rotary injection machines are ideal for small batch continuous production.

vertical injection machines are also rotary. They are a versatile choice to make ideal products that have a batch- delivery function than the standard injection machines, such as vertical injection machines. These rotary machines are called the vertical injection machine, which is used to make ideal products from two to more metals.

LS Mtron just unveiled their latest product WIZ-VR, energy saving hybrid low-bed vertical injection molding machine perfect for your insert-molded products.

A huge advantage over other competitors is that it has quick cycle times through high-speed clamping by dividing molding position and ejecting position and high-sensitivity mold protection, which provides safety.

LS Mtron further developed their vertical injection molding machine the WIZ-VR that enables 65~75% energy saving and low noise through high speed rotation and position control by controlling a servo motor-driven rotation table all with precise position repeatability.

By utilizing a servo motor we are able to rotate 180 degrees quicker and at the same time increase positioning accuracy.   The newly designed rotary table size is also designed to facilitate larger molds relative to the machine size.

One of the best features of the new WIZ-VR hybrid vertical injection molding machine is it’s low-bed ergonomic design compared to other competitors.  A lot of the vertical injection molding machines on the market requires the operator to stand on a raised platform to operate the mach

For example our WIZ-250VR  (250 TON hybrid vertical machine rotary table) is 840mm in height, which is about 60~80mm lower than that of other competitors, roughly 10% decrease in height over others.  As a LS Mtron official said, not only safety but also convenience and work efficiency have been increased.

Reiterating what was discussed above, LS Mtron WIZ-VR hybrid vertical injection molding machine has achieved 65-75% energy saving and low noise through RPM control and torque control using a servo motor when compared to a hydraulic system.

In addition, WIZ-VR’s hybrid system provides high reproducibility, high responsiveness and ultra-precise stable control.  In addition, there are water cooling savings due the servo motor replacing the hydraulic system.  With all these upgrades we are able reduce maintenance overall reliability is increased.

While horizontal molding machines were the first of their kind to become a standard in plastic manufacturing, vertical molding machines may be a more sustainable way of molding for certain applications and many manufacturers are now to utilize their many advantages. With the advancement of injection molding becoming more standard in consumer products, it"s time to delve deep into the differences of its sub-groups.

This article will map out the difference between vertical and horizontal molding machines and will mention the advantages of vertical injection molding.

If you were to visit the American Injection Molding Institute, you would see a variety of molding machines. But only by working on the machines would you be able to know exactly what works best for you.

Vertical molding machines are more flexible in terms of efficient production cycles, cost, and types of products it can handle. Take insert molding as an example. This is when a pre-formed product is inserted into a mold that needs plastic formed around it (see pictures).

Attempting to do this on a horizontal machine would be difficult and awkward as you would be fighting gravity, slowing down production and raising the risk of bad parts. Horizontal molding creates even greater risks when it comes to medical injection molding, which requires high tolerance parts.

With a vertical molding machine, the parts can easily be placed in the mold quickly and comfortably without having to worry about the insert becoming misaligned.

Book molds close on the inserts and hold the pieces tightly in place before, during, and after the molding process. Rotary tables can hold between 1-12 molds at a time and rotate giving the mold technician to time to replace the insert without holding up the molding process.

Multiple book molds on a rotary table can offer the fastest cycles and highest possible yields in molding. They also allow different molds for a family of products to be run at one time.

Another advantage of vertical injection moulding machine vs horizontal is that they take up well over half the space required for a horizontal molding machine. See the two machines pictured side-by-side:

Vertical injections can offer more control when the resin reaches the mold cavity through a short distance. Often times with horizontal machines, the plastic has to travel a longer distance to reach the mold which makes room for resin to cool too quickly and produce bad shots.

Clamping force is the amount of pressure required to keep the mold and product closed during the injection process. On vertical machines, especially when using book molds, the clamp is more of an added precaution since the top of the mold will be kept in place by gravity.

Shot size is the amount of molten plastic required in the injection process of the mold. Since the plastic is coming from the top, the size of the runner needed to complete a part is much less than that of a horizontal molding machine. This helps cut costs and reduce waste while keeping the process as efficient as possible.

Our injection molding process is a proven method as we have built full scale production molds for some of the largest companies in the world, as well as entry level tooling for start-up enterprises looking to break into the market.

We only use high-grade steel and quality injection molding materials for all of our molds, including 420 stainless steel (mainly for medical applications), S7, H13 and a host of other grades. All molds are designed in house, and a copy of the CAD files are included with the final product.

The ability to design, build and sample molds in house gives us a proven method of delivering quality and value in a timely fashion without the delays that some shops seem to encounter.

Our special book mold design greatly limits injection molding defects and allows secure placement of delicate inserts such as cannula, tubing, wires or filter membrane into the mold on a flat surface. Once in place the top mold half is gently closed around the inserts, preventing damage and ensuring proper location and alignment in the mold during the clamping and injection cycle.

In cases where book molds are not the best approach, we will design parting line molds which incorporate many of the other techniques we have developed over the years for producing defect free injection molded products.

Multiple book molds used in conjunction with a rotary table vertical molding machine provides maximum production capacity and flexibility by allowing finished parts to cure in the mold while indexing.

A product mix can easily be accommodated with this type of mold tooling. Typical medical injection moldingproducts such as spinal, epidural and biopsy needles, multi-lumen catheters, filters, surgical instruments and pacemaker components are produced with book molds

Insert moldingof contacts and stamping"s for the electronics and automotive industries are efficiently and successfully accomplished, as well as cable and connector over molding.

Aberdeen also provides mold tooling sampling and first article approval, initial start-up production, and long term or back-up contract insert molding.

The Principle: The GS loading system precisely meters the resin into the barrel by synchronizing with the speed of the screw. The 14:1 L/D screw, which is designed with no compression zone, achieves a first-in/first-out, even movement of the resin through the barrel. Finally, a positive-locking non-return valve blocks backflow and eliminates inconsistencies associated with a conventional check ring.

The Result: A homogeneous melt and stable process are maintained, and uncontrolled shear heating, material stagnation/degradation, random short shots and black spots are virtually eliminated. Additionally, barrel wear, carbonization and maintence requirements are reduced. Working together with Sumitomo (SHI) Demag"s Z-Molding capabilities for consistent and complete low-pressure filling and effective venting of gases, the industry"s highest level of shot-to-shot repeatability and defect-free parts is achieved.

The medical sector has embraced the high standards that plastic injection molding can offer. Insert molding, especially on a vertical molding press, can hold tight tolerances while also offering design flexibility. These machines provide quicker cycle runs and the option of running up to twelve different molds on one machine at the same time.

Tight tolerances and design flexibility make vertical injection molding attractive over horizontal molding in some medical device design needs.  For example, many of today’s new and innovative healthcare devices are made from a combination of thermoplastic resin and specialty medical components like cannula, tubing, wires, cables, stampings and delicate sensors. Recent advances in molding technology offer the ability to mold delicate components directly into the devices, rather than being incorporated later through machining, gluing, or ultrasonic welding. Now, while this technology might not be brand new in and of itself, the process has been re-invented with the use of book molds.

The vast majority of vertical molding equipment on the market is configured with the top half of the mold attached to the upper platen of the molding machine. The top then closes down with force onto the bottom plate.

Traditionally, it is often difficult to hold delicate inserts in place during the injection molding process (even more so with horizontal molding machines). The possibility for delicate inserts to be interrupted or misplaced is often greater than what manufacturing managers would like to admit.

The inserts loaded in the bottom half must be held securely in place so that when the top closes, neither the mold nor the delicate insert is damaged. Damage to the mold can be substantial, especially when the two halves close under high tonnage around steel or other rigid materials, so it is important to locate and secure components in place carefully during molding. Still, factors such as operator misplacement or shuttle/rotary table vibration can mean damage to the mold or the inserts.

A solution that has helped eliminate these complications is using book molds mounted on a rotary table press. Book molds have become prevalent in the production of medical devices, specifically for medical injection molding.

Book molds differ from traditional molds as they are typically hinged to each other and open/close like a book (hence the name). These molds can be used on traditional vertical presses, but are commonly found on vertical molding machines with rotary tables.

Book molds are mounted to vertical clamp/vertical injection molding machines that have multi-station rotary tables. The molds consist of top and bottom mold halves that are connected by a hinge in the back so the top half can be lifted open.

Ejectors are installed in the bottom half to lift out finished parts along with the sprue and runner, so multiple cavities are often well suited for book molds. A handle is often mounted on the top half for easy opening, which can be done either manually by the press operator, or with a stationary ramp.

One service that is best used with book molds is overmolding. Overmolding is often confused with insert molding since it is performed on the same injection molding machines. Overmolding versus insert molding is actually more simple than what most companies make them out to be. Overmolding is a subset of insert molding. All overmolding is insert molding, but it does not go both ways.

There are many different preferences to what shops call overmolding and insert molding. Insert molding is often when a pre-produced part is inserted into a mold and receives a mold around it.

Overmolding is a similar process but it is typically when a part needs a second operation over the initial insert molding. It is still an insert molded product, but referred to as overmolding. Overmolding versus insert molding is also commonly referred to as “injection molding with a second operation”, or “insert molding with an overmolded sequence.”

For a medical device engineer, the manufacturing process should always be in the forefront of his/her mind as manufacturing costs quickly rise with the complexity of each part. The best way to keep manufacturing efforts efficient and affordable is to find a capable vertical molding manufacturer to help through the entire process.

A vertical gantry frame machine with two thermoplastic injection units injecting from above proves to be a "gamechanger" for the production of 2C-automotive components at ELDISY in the German Gardelegen.

Multi-component injection molding is a process of great importance and high demand. Because it enables the combination of two or more plastic components with different properties in one injection molding process. In other words, multi-component injection molding allows different molded parts to be combined inline in the injection molding machine. This replaces assembly operations. Today, no branch of industry can do without the resulting productivity and precision advantages (due to the consistently correct position and form-fit connection). The automotive industry is outstanding in terms of quantities and innovation. Currently, the switch to electric drive technology is proving to be an upswing to the next level of innovation. This is because, because instead of the combustion engine noises, the wind or rolling noises of the tires come to the fore, as do body vibrations.

This is the environment in which Messrs. ELDISY (= Elastomer Sealing Systems), who focuses on sealing systems for automotive and industrial applications and operates with seven production sites worldwide. The company mainly produces extruded profile seals for all door openings in automobiles, as well as a wide range of single- and multi-component body components.

One of the components from this parts package is the approximately 180 cm wide "water box cover" installed in front of the windshield. It consists of an arc-shaped polypropylene structure combined with elastic TPE-sections at the contact points to the metal body and at the through-holes for the windshield wipers

2-component automotive parts are not new for the ELDISY injection molding department. Examples from previous contract manufacturing include water deflectors, sill strips, joint seals or window guides. The production machines used for this purpose were or are the 2C variants of conventional horizontal injection molding machines from various manufacturers. All of them are equipped with a rotary table on the moving machine platen and injection by means of two injection units in piggyback arrangement through the fixed machine platen.

Smaller 2C-parts have been produced at ELDISY up to now with conventional horizontal machines with a vertical rotary table in the clamping unit and two injection units in piggyback- arrangement.

Dr. Detlef Scharge, Eldisy"s plant manager for many years but recently retired, comments: "For many years, this concept was regarded by us as the "state-of-the-art system" for multi-component injection molding. We used it consistently over a wide clamping force range. However, the larger the machines became, the more serious the system-related disadvantages became. In particular, the horizontal rotary axis, including the rotary feedthroughs for the media fed to the mold, suffered from the one-sided weight load of the injection molds hanging on the rotary tables. This resulted in increased maintenance and servicing costs. The hot runner design was also more restricted than desirable with increasing mold size due to the system-related close proximity of the injection positions of the piggyback units. Therefore, the search for alternatives had been on our agenda for some time. But the real catalyst for this was the order for the water box cover. Because of its size, we had to find a solution, as we would have needed a 16,000 kN machine to install the mold for it according to the old principle, which would have been uneconomical both for the technical reasons already mentioned and because of the investment required for this."

This opened the door for a market research. Chance came to the rescue, namely at the K-2019 trade show booth of the LWB-Steinl company. There, LWB had exhibited a production cell with a large rotary table clamping unit with thermoplastic injection unit. A similar layout seemed to be the alternative ELDISY management was looking for. It was the starting point for the discussions. By coincidence, the LWB managers responsible for design and sales and company boss Peter Steinl were also present at this time and immediately took up the ideas of the ELDISY management and were able to sketch out a feasible machine concept together with them.

Helpful was also the presentable additional reference of a large machine delivered in 2019 in the form of a precision sheet metal press with a clamping force of 19,000 kN with a clamping area of 2.5 x 2.5 m. (Note: A project report on this can be viewed on the LWB website as well as in relevant trade magazines from fall 2019).

Both of these things together then paved the way for a concrete project inquiry that initiated the system change in 2C-large-part production. And this despite the fact that LWB had not previously been "on the cards" as a possible supplier for plastic injection molding machines of this size.

At the end of the subsequent concept phase, a machine with the specific type designation VR 12000 / 1097 / 220 Dual Sonder took shape. This bulky designation stands for a machine from the VR (vertical frame) series. Its clamping concept is a specific LWB development and occupies a special position between the tie-bar-less C-frame machines and the conventional tie-bar machines. The central components are portal frame modules as carriers for the mold fixing platens and the press modules for generating the clamping force. The VR series has a modular design throughout and is therefore largely freely scalable. The reason for this, and this is the great advantage of the VR system, is that the size of the clamping unit is not tied to the size of castings. Since the frame modules are made from thick sheet semifinished products, this allows an individual and largely free choice of dimensions. In this specific case, the portal opening was selected in consultation with the customer and the mold maker to accommodate a rotary table with a turning diameter of 2720 mm, on which molds with a platen size of 2200 x 1600 mm or 2000 x 1800 mm can be clamped. This made it possible to align the machine to the clamping force requirement (maximum 12,000 kN) and not to the given size specifications of conventional horizontal machines.

In addition to flexibility in dimensioning, the VR-machine-system from LWB-Steinl also offers other advantages: the clamping unit, for example, which consists of two frame modules, offers the possibility of adjusting or balancing the clamping force to the two moldcavities, if required, thanks to the four pressure modules positioned above both frame units. The horizontal rotary plane of the rotary table eliminates all weight influences on its rotary axis bearing and the rotary feedthroughs for the coolants and the electro supplies.

The injection unit positions also differ from the usual ones. Instead of the piggyback configuration with close injection spacing through a central opening in the fixed machine platen, the two units are mounted separately on the top of the clamping frame modules and are thus easily accessible.

Another advantage of the VR-clamping unit is its slim structure. This provides good accessibility to the mold area by means of an industrial robot positioned next to the machine - and is thus also comparatively easier and more space-saving than with the horizontal machines.

For the (infrequent) mold changes, a mold station with a mechanical telescopic cross transport is docked to the machine and the mold, which weighs up to 18 tons, is pulled out of the clamping unit. The in-house transport of the mold station and the mold is handled by the overhead crane.

Another advantage of the VR-concept over a conventional horizontal injection molding machine should not go unmentioned: Due to the vertical configuration, the floor space requirement is significantly smaller than that of the horizontal machine. However, the vertical space requirement is comparatively taller and places demands on the hall height in this respect.

Commenting on the experience gained so far with the alternative 2C-injection-molding-cell, ELDISY Managing Director Dipl.-Ing. Elmar Stoffel summarizes on behalf of the entire project team: "We consider the new machine concept to have eliminated all our points of criticism of the injection molding systems used to date and will thus be able to supply the molded parts required by Volkswagen. Our confidence in the correctness of the decision has prompted us to order three more VR-machines from LWB-Steinl, this time with 9000 and 18000 kN. Several more are in concrete planning. With this, we have completed the system change and assume that we have thus further secured our competitiveness as an automotive supplier."

The ELDISY production team confirms the correctness of the decision in favor of the LWB machine technology: From left: LWB sales engineer Thomas Vodnansky, plastics engineer Christian Walter, Dr. Detlef Scharge - retired plant manager, Dipl.-Ing.
