Engel Delivers Its Largest Ever Injection Molding Machines

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.

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.

Moving Heavy Metal

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.

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.

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.

ADS, which places a high level of corporate emphasis on sustainability, said it has made significant investments in new equipment in recent years to help it more efficiently create its products, which are used to move water and now include high levels of recycled plastic. For Engel, which was recently been granted an EcoVadis gold rating, sustainability is also a top priority.

More and Bigger to Come

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.
