The Overmolding Process
Overmold injection molding is a two-step process wherein a completed plastic or metal entity is placed into the mold site of an LSR mold, after which the LSR is overmolded directly onto the part.
One of the benefits of liquid silicone overmolded parts and components is that the manufacturing process allows for the use of a non-plastic substrate, such as steel. It is important to note that overmolding is the only way to incorporate materials, aside from other thermoplastics and LSRs, into the injection molding process.
Benefits of Overmolding
LSR / plastic injection molding is a cost-effective and versatile process used by manufacturers in a large number of industries and applications. From LSR overmolded handles to complex electronic assemblies, there are multiple reasons why overmolding is a good choice for your project:
- Cost and time savings —By molding silicone directly onto a metal or plastic substrate, you’ll save the expense and time required to assemble a complex part manually. This can dramatically reduce your manufacturing costs and turnaround time, allowing you to get your product to market more economically.
- Design flexibility —LSR/thermoplastic injection molding is excellent for meeting the complex design requirements of the automotive and medical industries. Overmolding produces parts that are waterproof, airtight, and more resistant to shock and vibrations.
- Quality control —The LSR/plastic injection overmolding process offers high tolerance and strict quality control, making it suitable for use in any application where precision is required. SIMTEC can produce overmolded parts to your exact specifications, including devices that require manufacturing in a Class VII or Class VIII clean room.

LSR is the raw material of choice for various overmolding injection molding applications. It offers superior durability, high fatigue and tear resistance, excellent insulation, and environmental sealing properties when used as a housing for delicate components. It is also hypoallergenic/biocompatible.
As a result, custom LSR overmolding/insert plastic molding is often used in the manufacturing of medical devices, electronics and automotive parts, as well as a wide range of consumer goods.
