Reduce Your Manufacturing Process from 12 Steps to 4

Crown Plastics’ unique belt process enables multiple layers of woven or non-woven thermoplastic material and polymer to be processed simultaneously and continuously for the entire length of the rolls of material. This differentiation allows for the production of a single, large-quantity roll of finished composite material versus the small-batch runs produced by traditional prepreg processes. This approach eliminates the need for semipreg, as well as with the lengthy and costly processes that go along with it.

Thermoplastic Production with Others

The lengthy multi-step
prepreg production process,
leading to higher costs and
greater lead times.

Crown’s streamlined thermoplastic production process, eliminating the need for prepregs and saving manufacturers significant costs and time.
