Today, instead of waiting for schools bring manufacturing and technology back in, many companies are bringing the schools to their plants via open houses, apprenticeships, job shadowing, and more. Four years ago...
That burgeoning need for new manufacturing workers has been met with a mere trickle of new talent. Some blame a shift in educational priorities. One of these is John Winzeler, president of Chicago custom injection molder Winzeler Gear (see July On-Site feature) and a third-generation manufacturing professional.
At the very moment that manufacturing is resurgent in the U.S., the plastics industry is ill-equipped to respond. Reaping the twin harvests of a ready-to-retire skilled workforce and a meager crop of new talent...
Once a 3D CAD model is uploaded to MBA Mold, you can specify material, quantity, finish, overall expectation of the part in a notes section, and essentially, communicate as much information about that part as possible at the time of upload.
CNC Milling Firstcut toolpaths the digital part design to our CNC machines, instructing the end mills where to travel on the X, Y and Z planes.
Injection molding is a manufacturing process for producing plastic injection molds from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity by a reciprocating screw or a ram injector.
Not only injection mold temperature determines melt temperature as it moves quickly through the mold. The melt temperature itself as it starts its journey through the injection mold (self-evidently) is the reference point. Speed of injection, particularly in thin sections, is of huge influence, as it will determine the degree of shear heating.
Many engineering materials like PBT (Polybutylene terephthalate) have a tendency of out-gassing. The best practices that I have to date are: Add 10mm wide vents spaced 30mm from each other all the way around parting line. Always follow the recommendations of the material company for vent depth.
