Dear Artur,

Meter mixing equipment for injection of fast curing urethane into silicone
rubber tooling is readily available. Your material supplier should be able
to put you in touch with several equipment vendors. It is common practice
to use this equipment for multiple prototypes or low volume production. The
fast curing urethanes now have good physical and acceptable heat distortion
properties for many applications.
