Facilities
EPTAM is equipped with 29 injection molding machines. Production molding machines are 2 years old on average.
EPTAM Lancaster, MA facility
EPTAM’s Lancaster, MA facility is a completely controlled environment, with a recently expanded ISO Class 8 cleanroom. Capabilities include a wide range of press tonnage—28-550 ton with plans to expand—and are committed to continuous reinvestment in operations, with $2 million recently invested in upgrading our cleanroom and purchasing new machines.
EPTAM Leominster, MA facility
EPTAM’s Leominster, MA facility boasts a fully controlled environment with two certified ISO Class 8 clean rooms, one for thermoplastic and one for silicone. We have a diverse range of injection machines, including LSR machines with a capacity ranging from 14 to 120 Tons, and Thermoplastic machines with a capacity of 50 to over 200 Tons. This facility has separate compression room space and is designed to allow for future expansion of equipment or automated assembly cells. Our expertise also includes over-molding silicone onto various materials such as metals, plastics, mesh screens, and other silicones. We have extensive knowledge in LSR injection.
EPTAM is committed to meeting customer scalability requirements. When any single piece of equipment reaches 70% capacity, an additional machine is ordered.
EPTAM Silicone is equipped with LSR injection molding machines ranging from 14-120 ton and compression presses ranging from 10-100 tons. Additionally, we have thermoplastic injection machines ranging from 50-130+ tons with allocated space for additional equipment and capacity. Albright offers prototyping and production tooling with the ability to build a wide range of tooling in house. This is supported by Brother and Topper CNC machines.
