Plastic injection molding is a manufacturing process where resin in a barrel is heated to a molten state, then shot into a mold to form a final production-grade thermoplastic part.

An Engel spokesperson told Plastics Technology that ADS and Infiltrator wanted to keep most of the key details around the machine close to the vest, but Engel says going forward it will be manufacturing even larger machines, including the possibility of presses with clamp forces exceeding 12,000 tons and shot weights of a few hundred kilograms. For these machines, maximum platen size would 13 by 10 ft, with the ability to run molds weighing up to 444,000 lb and offer material throughput of 4400 lb/hr.

When determining the best ejection option for a tool, molders must consider the ejector’s surface area, location and style.

Austrian injection molding machine and automation supplier Engel (Schwertberg) has delivered the two largest-ever injection molding it has built to the U.S., shipping a pair of 8000-ton duo combi machines to Advanced Drainage Systems‘ (ADS) subsidiary Infiltrator Water Technologies (IWT) in Winchester, Ky.

Engel notes that dozens of individuals worked thousands of hours with a perfect safety record to complete the project. Engel received the purchase order in November 2020, with the handover of the first machine completed in February 2022. In Februray 2023, the second machine, a replica of the first, was delivered.

When, how, what and why to automate — leading robotics suppliers and forward-thinking moldmakers will share their insights on automating manufacturing at collocated event.

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.

Our helpful design aid demonstrates part features that are too thin or too thick, bad bosses, right and wrong ribs, and other considerations to be mindful of while designing parts for injection molding.

Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.

Because of the initial capital investment in tooling, injection molding makes sense for higher volumes of parts. Our mold cost starts at $1,495 and will vary depending on part geometry and complexity. Other factors that will impact injection molding cost are lead times and material.

The enormous size of these machines required new manufacturing facilities to house them. Infiltrator completed a 59,000-ft2 building expansion over the same time as the parts were delivered. Over 2 months, the machine was assembled while the building and all the necessary auxiliary equipment and utilities were installed, including a 150-ton overhead crane intended to move molds in and out of the machine but used to help assemble the new press in the interim.
