Mold Classifications

Use this chart to help you decide what classification you want us to design your mold to. Classifications designate the number of cycles the mold can be used before the customer should expect to pay for “wear and tear” repairs. Typically, a high volume (millions of parts per year), multi-cavity mold with a long product life expectancy will be built to the highest classification.
