Non-Export Tooling

What is non-export tooling?

Non-export tooling is tooling built outside of the US that cannot be transferred from the molder/mold maker.  Tooling will often be built to non-standard specifications using local steels.    It will have a stated tool life.  At the end of the tool life a new tool will have to be purchased in order to produce more parts.

SPI Mold Finish Standards

The SPI mold finish ratings allow you to specify a general mold surface finish.   The finish is a call-out on the mold itself, not on the finished product as the final part finish will vary with processing, plastic material, mold quality and mold steel.  If you need exact texture matching of plastic parts then a more detailed standard is required.
