Mold Classifications Plastics Manufacturing
Mold Classification

When you build a mold with Acorn-Gencon Plastics, you will have to make a decision on what mold classification you want us to design your mold to. Typically, a high volume (millions of parts per year), multi-cavity mold with a long product life expectation will be built to the highest classification. Classifications designate the number of cycles the mold will repeat before the customer can expect to pay for “wear and tear” repairs.
