Liquid Silicone Rubber Overmolding Process The process of injection molding involves two steps: First, the complete plastic or metal body is placed into an LSR (Liquid Silicone Rubber) mold, and then the LSR is injected directly onto the part.

One of the benefits of liquid silicone overmolding parts and assemblies is that non-plastic substrates such as steel, aluminum alloys, etc. are allowed to be used in the manufacturing process. It is worth noting that the lagging process is the only way to introduce material (besides other thermoplastics and LSR) into the injection process.

LSR injection molding is a relatively cost-effective and versatile process used by manufacturers in numerous industries and applications. From various LSR overmolded handles and housings to complex electronic assemblies, applications include health products, automobiles, baby products, medical products, diving products, kitchen utensils and seals. This also shows that the silicone rubber lagging process has many advantages:

Cost and time savings – By molding silicone directly onto metal or plastic substrates, you can save money and time manually assembling complex parts. This can greatly reduce manufacturing costs and turnaround time, and can bring products to market more economically.

Design Flexibility – LSR injection molding is ideal for complex design requirements in the automotive and medical industries. The silicone rubber lagging process produces a product that is waterproof, airtight and more resistant to shock and vibration.

Quality Control – LSR injection molding has high tolerances and strict quality control, making it suitable for any application where precision is required. ES Dongcheng can produce liquid silicone overmolding process silicone rubber parts to your exact specifications, including those that need to be manufactured in a Class VII or VIII cleanroom.

Both the overmolding process and the two-shot injection molding process combine two substrates during the molding process to form a multi-substrate assembly. In the LSR overmolding process, a metal block or plastic part is placed on a liquid silicone mold to produce a multi-substrate assembly, providing a variety of substrate combinations. In a two-shot injection molding process, both materials are molded in the same process, with in-machine cavity-to-cavity alignment for superior bonding and precise placement.

LSR (Liquid Silicone) is the raw material of choice for injection molding applications in a variety of overmolding processes. When used as an enclosure for precision components, it offers exceptional durability, high fatigue and tear resistance, excellent insulation, and environmental sealing properties. At the same time, it is also hypoallergenic and biocompatible. Therefore, custom LSR lagging processes can often be used to manufacture medical devices, electronic and automotive parts, and various consumer products.
