Resin-based direct tooling

Date: Fri Jan 22 1999 - 04:17:02 EET

   Dear All:

 I've been looking for direct tooling methods which can make mold
 without any human intervention so far.
 Yeah....The future manufacturing system,I always think,should be
 comprised of unmanned processes,which are not skill-dependent,but
 system-dependent,as you know.
 During my eager search,I hear there seem to be some methods which
 are capable of making resin(photopolymer)-based mold directly from
 3D CAD model of mold.

 The minimum requirements for injection mold,I think,are as follow.

    1. Accuracy : +/- 0.05 mm
    2. Tool life : 100 - 200 shots (All my applications are for eng-
                   ineering sample making)
    3. Materials to be injected : ABS,PC or glass-filled.
    4. Turnaround : Within 2 days from 3D model to physical mold
                    regardless of its shape.

 Is there anyone who happened to know of any process which can meet
 the above requirements ?
 Any information you can give me would be greatly apprecicated.
 Thank you in advance.

    Best regards.
