With the ability to turn CAD models into real molded parts in as little as a day, Protomold’s rapid injection molding service is undeniably fast. Still, the service has never been a cure-all for the long lead time blues because Protomold’s automated tooling and molding systems impose size and geometry limitations that rule out some plastic part designs. Earlier today at the Pacific Design & Manufacturing Show in Anaheim, the company literally had some big news about those limitations. According to senior quality engineer Kevin Crystal, Protomold’s rapid injection molding system now accommodates parts with projected areas up to 175 in2, up from 75 in2 in the past. Maximum x-y dimensions have increased to 13.5 x 30.5 inches, subject to that projected area limit. Maximum depth for the large parts is now 3 inches from either side of the parting line, or 6-inches total for parts that can be divided equally between mold halves. Part volume now tops out at 59 in3. Protomold will run the large parts on a newly-acquired 750-ton molding machine. Lead time for the big parts will initially be 15 days.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
