This hydraulic coil press was designed and manufactured by ETSM Technical Services, Ltd. for use in coil winding applications by the electrical power transformer industry. It was manufactured using CNC machining, laser cutting, and MIG metal core welding. Every part of the machine was fabricated. Specifications included 150 ton capacity, four pillar type down stroking, 1800mm per minute travel speed and 10mm per minute pressing speed.

This machine includes 12″ color touchscreen interface controls, a final height and tonnage report that is emailed to the user, two beacon lights that go on during operation, a warning buzzer before motion commences, and a four-foot light curtain on the open side. We will build to your supplied specifications, and also to Ontario Press Code specifications and CSA electrical standards. We offer on-site commissioning and start-up. Ship time for this project was four months to Ontario, Canada.
