One approach is to substitute metals with reinforced thermoplastics. PROCESSING METHODOLOGIES EXPLAINED Die Casting - Metals Die casting is a type of metal casting process that injects molten metal into a mold cavity under high pressure. However, this can depend on a number of factors such as metal type, part complexity, and maintenance.

Therma-Tech formulations offer similar heat transfer, dissipation, and cooling capabilities to metals, when heat is transmitted into air. This combined with the design freedom, weight reduction, and cost advantages of thermoplastics, opens up the possibility to use them for metal replacement. Switching materials from a metal to a polymer carries large and potentially costly risks in terms of both performance and production, so Avient Design was consulted to help alleviate these concerns.

When a metal propeller blade strikes a submersed obstacle with severe impact forces, it can permanently bend or break. The innovative blade design of Piranha’s Hydrothrust propeller provides 400% more reverse thrust than standard propellers and twice as much as competing metal props. Injection molding with long fiber composites makes it easy to add feature details like our Hydrobites that would be difficult and expensive to produce in metal,” said Stahl.

Long fiber reinforced thermoplastics provide structural performance that can go head-to- head with metals at a fraction of their weight while retaining the processing ease of injection molding. Complēt™ LGF Long glass fiber reinforced engineering resins with enhanced mechanical properties that allow for metal replacement. Complēt™ LCF Long carbon fiber reinforced materials have higher rigidity/modulus, higher strength, lighter weight, and more marketability potential than glass fiber, making it the ideal fiber reinforcement for metal replacement.

Working closely with the producer, the Avient team recommended customizing a high density, engineered material formulation as an alternative to metal. Switching from metal forming to injection molding would also enable processing cost savings and expanded design freedom. These materials are able to be vacuum metalized or electroplated as well, to reproduce the premium metal finish that leading spirits makers prefer.
