What Is Multi-Shot Injection Molding?

Multi-shot or multi-component injection molding is an overarching term that describes an injection molding process where two or more materials are molded within the same molding machine and during the same molding cycle, resulting in an integrated molded component with multiple materials and substrates. In the context of two-shot molding, both LSR and thermoplastic parts are molded and combined in the same molding cycle. The molds for LSR and thermoplastic parts share the same platen in the molding machine, typically with the LSR mold positioned on top and the thermoplastics mold on the bottom. Regarding injection molding, two types of molds are commonly used: transfer molds and rotary molds. In a transfer molding process, after molding the thermoplastic parts, they are robotically removed from the mold and transferred up to the LSR mold for completion.

Why Multi-Shot Injection Molding

Multi-shot molding presents a superior alternative to conventional injection molding methods, including single injection and two-shot molding. In traditional processes, where a single or double injection is utilized, materials are injected into separate molds to create the final products. In contrast, multi-shot injection allows for the simultaneous injection of two or more materials into a single mold. This innovative approach enables the integration of multiple materials within a single production cycle.

Benefits of Multi-Shot LSR Molding in Silicone

Cost and Time Savings

Multi-shot LSR molding, a form of silicone injection molding, offers several advantages over traditional single-shot methods. It enables manufacturers to integrate multiple materials into a single part in a single machinery process, reducing manufacturing steps and overall costs. The streamlined process also translates to time savings.

Efficiency and Quality

The process also facilitates the incorporation of multiple colors during production, eliminating the need for secondary painting or coating steps. Additionally, it mitigates problems arising from material incompatibilities, as each material remains isolated until shortly before injection molding.

Performance Enhancement

The outcome is higher-quality parts with enhanced strength and durability compared to single-shot processes. A silicone multi-shot injection mould ensures superior color consistency through the creation of a master color during each production run. With these advantages, it emerges as an efficient and cost-effective alternative to traditional manufacturing techniques.

Optimization

LSR Multi-Shot technology allows for the optimization of part weight, space, complex designs, and the integration of multiple materials and functions into a single component. It is particularly well-suited for parts with tight tolerances, complicated geometries, and consistency requirements in wall thickness.
