We run all three, so we have no reason to steer a part toward one of them. The choice comes down to volume, part size, tooling budget, and what the compound costs.
Compression
The lowest tooling cost of the three, and the most economical route for large parts, low volumes, and expensive compounds where material waste matters. Cycle times are longer, and part-to-part consistency depends more on operator technique.
Transfer
Sits between the other two on cost and on control. It handles intricate geometry and molded-in inserts better than compression, with tighter part-to-part consistency, at moderate tooling cost.
Injection
Fastest cycle and best repeatability, with the highest tooling investment. It earns that investment back at volume. Our injection presses run computer-controlled, with heat, pressure, and cure time monitored shot to shot.
If you are not sure where your part belongs, send the print and the annual volume. We will tell you which process we would quote it in, including the cases where the cheaper tool is the right call.
