The plastics molding industry is extremely competitive. Any advantage that can be had can make the difference between profit and loss on almost any job. You cannot allow your competition to have the advantage of greatly reduced mold wear and higher profits due to molding runs that are uninterrupted by maintenance problems.
Cryogenic processing is very successful in reducing wear on runners and in cavities, even when highly abrasive materials are being molded. Our customers typically see two to three times the life on molds, pins, and other parts. Cryogenic processing has shown to stop the seizing of ejector pins. Our analysis is that the pins actually grow in use due to retained austenite transforming to martensite. This causes the pins to seize tightly. Cryogenic treatment prevents this from happening.
Side actions show reduced wear, and parting lines stay sharp.
One of the biggest costs of a mold is polishing. The cost of polishing is up to 30% of the total mold cost. Cryogenic processing reduces the time required to polish a mold. The process produces a more evenly hard surface that is easier to polish.
