Chinese tool makers are gaining ground in precision aluminum tooling, according to a presentation this morning at the annual technical conference of the Society of Plastics Engineers. For starters, aluminum billet is cheaper in China than the United States, according to Peter Mooney, president of Plastics Custom Research Services. Then mold makers laminate billets and precision machine the shapes for molds. As a result, it’s less expensive to make machined aluminum molds for complex shapes. The tools are particularly important for rotational molding.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
