Use of plastic injection: Prototype injection molding requires plastic injection, which requires a special set of skills, does skilled labor with a specific qualification, which invites the hassle of finding a suitable candidate. Apart from that, finding especially skilled employees can put a strain on the entire budget and the process.

An improved line of large two-platen injection presses offers new sizes plus greater speed, educed maintenance, more operator-friendly design, and added flexibility for a range of molding requirements.

In a release, Jim Moran, business development manager at Engel North America, laid out the logistical challenges of transporting the machines from Austria to Kentucky. Actually, since each press was fully assembled and tested prior to shipping and then disassembled to be delivered to the U.S., the company was technically shipping components with 29 truckloads of parts eventually arriving in Kentucky from Austria, including the platens which were transported to and from St. Valentin via barge on the Danube River.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.

The Engel duo 130000/130000H/8200 combi machines each feature two 85,000 cm³ (approx. 2900 oz.) injection units capable of a combined total shot weight of 270 lbs (122 kg). In terms of footprint, the machines measure 96 feet (29.3 meters) long and 37 feet (6.4 meters) wide. Big no doubt, but in relation to their shot size and clamp force, Engel points out that these behemoths actually have a relatively small footprint made possible by the duo’s two-platen design.

Low Financial Risk: It may be known as the most expensive prototyping process, but when it comes to producing with right prototype material selection, it will be a smart investment. It can help you produce thousands of parts in no time. Those parts will be your property and can be used to produce small fragmented plastic parts.

It is often used to produce quick and high-quality prototypes and samples. The molds are two pieces that are held together with force and extreme pressure to create an accurate prototype after the process of prototype material selection that can be used to study the efficiency and usability of a part or product.

Most expensive prototyping process: As discussed earlier, manufacturing a prototype will be less expensive, but the investment is relatively high. The cost of the equipment and the injection materials is very much higher. The labor cost is also something that will prove to be challenging with prototype injection molding.

AIM Processing has parlayed small part molding expertise and aggressive automation, even for short run production, into a highly successful custom molding business.
