Silicone Injection Moulding – Moulded Parts for the Medical and Pharmaceutical Industry

What can you expect from RAUMEDIC as a silicone injection moulding company?

U-Konnektoren und Überleitsystem
U connectors and feed systems produced using silicone injection moulding

At RAUMEDIC we understand silicone injection moulding as part of the whole. Drawing on our silicone experts' many years of experience, we shape our customers' ideas into customised system solutions. The cornerstones are an optimal material selection and high-precision cold-runner moulds with a direct sprue and needle shut-off system, or alternatively with an open nozzle system. Our production environment, which is specially equipped for the requirements of silicone injection moulding, permits highly automated production using multi-cavity moulds with short cycle times and very low reject rates. The entire value-added process occurs as per GMP guidelines under clean room conditions according to ISO class 7.
