Multi-shot injection molding, also known as two-shot molding, is a process where multiple materials are injected into the mold simultaneously. This differs from traditional techniques that involve only a single injection. Multi-shot molding is an enhanced version of the two-shot process, as it enables the combination of multiple materials into one production cell.
The multi-component injection molding process represents the latest in liquid silicone rubber (LSR)/thermoplastic injection technologies and can offer numerous advantages for your company’s manufacturing applications.
The multi-injection molding process entails the integration of three materials — LSR, a metal and a thermoplastic — into one component within a single manufacturing cell. The injections are applied via independent nozzles at multiple surface locations. This enables the fast, efficient production of a wide variety of products ranging from automotive components to hinges, handles and many types of movable parts. See it in action below.
Multi-injection molding offers numerous functional and aesthetic benefits. For one, product designers have greater flexibility to create more innovative products, which is advantageous for users that require customization. Manufacturers and designers can easily incorporate multiple colors, combine otherwise incompatible materials and apply softer materials over hard surfaces.
Multi-shot molding also eliminates the need for secondary manufacturing processes for adding text, graphics or logos — this can be accomplished in a single step, which saves time and reduces production and labor costs. Manufacturers can improve the appearance of complex products, while simultaneously reducing process steps, which can dramatically improve overall operating efficiency.
Another important multi-shot injection molding benefit is the improved craftsmanship. The combination of fewer production steps and a cleaner, smoother transition of materials creates a more efficient manufacturing process that reduces the likelihood of errors and re-dos. This results in improved quality and a reduction in waste materials caused by production mistakes.
Finally, multi-shot injection molding can improve the durability of the finished product, resulting in a longer lifespan and reducing the need for a premature replacement. This can give you an edge over your competitors, as you’ll be able to provide a long-lasting, higher-quality product at an affordable price.
