Insert molding combines plastic with metal or other components into a single part. This process reduces assembly requirements, improves component strength, and provides a cost-effective
solution for complex applications.
Viking Plastics provides unique solutions for converting a metal component to plastic. The demand for conversions is constantly increasing as more companies seek ways to reduce weight, improve efficiency, and reduce costs. Viking offers a variety of plastics, including ABS, PC, PC/ABS, PPS, PEI, and various grades of nylon and glass-filled nylons.
Plastic offers several benefits:
The process of metal-to-plastic conversion starts with an assessment of the moldability of the component, followed by feedback on design changes for manufacturability (DFM) via injection molding. Once the design is updated, a Finite Element Analysis (FEA) is performed to understand loading, stresses, and base material strength requirements. Armed with this information, the Viking Plastics team works with material suppliers to locate suitable resins with the proper characteristics for the application. This includes an analysis of material strength, environmental exposure, chemical resistance, and other application requirements.
With a base design and material selected, the FEA is rerun to determine confidence and safety factors. Once these are established, flow analysis software is utilized to optimize gate location and size. A warpage analysis provides feedback on projected results from the molding process and offers guidance on the location of water lines and potential for part model tweaks to compensate for shrink and warp. Typically, customers then order a prototype mold/parts for confirmation and testing, followed by production tooling and quantities to meet demand.
Viking Plastics is an injection molding and value-added assembly service provider. A privately-held, American-owned company founded in 1972, Viking Plastics has prospered by developing innovative, cost-saving solutions for tough engineering challenges and leveraging our expertise in custom molding capabilities. We currently have more than 50 injection molding machines globally and several automated assembly cells.
