Re: Best Process for Small Production Run

Hi Allen:

This seems to be a perfect application for a rubber mold (platinum based silicone) and fast-setting polyurethane resins. The fast-setting resins, when processed under vacuum, will deliver high quality parts and will not degrade the mold quickly. For your inserts you could make a multi-cavity silicone mold, so that you can produce about 10 parts at once.

Many of our customers (service bureaus) that run CAMATTINI Vacuum Casting & Polyurethane Injection System often run production jobs for quantities in the range of 200-1000 units.

In fact, your colleagues at Ft. Lauderdale, FL have our machine and use our resins. They can probably give you some feedback regarding this application.

Please contact me off line for a recommendation of a reputable service bureau for such a project.

Best regards,
Michael Tsenter

I have been asked the best way to produce 50 of the housings and 400 of the insert pockets without using production tooling/injection molding. Is this job too big for rubber tooling, or is there other alternatives better suited for these size parts and quantities.
