Product Description

LSR overmolding & Liquid Silicone Insert Molding is an injection & transfer compression
molding process which molded & cover silicone rubber onto a substrate material like plastic & thermoplastics, metal(magnet, steel,
aluminium or brass), wire, electronic parts(PCB circuit board), glass with the assistance of bonding adhesive or glue to complete
the final part.
LSR overmolding also called two-shot Molding, Liquid Silicone Rubber Overmolding or LSR Insert Molding.

LSR overmolding process.First step,substrate treatment:Before the liquid silicone (LSR) material is wrapped on the substrates,the surface of the substrate
must be treated well.It is mainly to ensure that the substrate surface is smooth and without defects,so as not to crack when the
force is applied.And the substrate surface must be clean and withou oil.
Second,prime coating:withou prime,liquid silicone(LSR) can not bond with other material(metal,thermoplastics) .So when prcess lsr
overmolding to metal/plastic,we need to coat prime on the substrates.Different substrate,different prime coating.

**Different substrate,different prime coating.

Lastly,liquid silicone rubber injection molding.Inject the liquid silicone (LSR) material into mold cavity by liquid silicone
rubber injection molding maching to wrap & cover the substrate.

LSR overmolding injection temperature is different from the substrates.
Therefore, when design LSR overmolding structure, we should take into account the suitability of the substrate and liquid
silicone(LSR).
Not all plastic material can be used as substrate in LSR overmolding process.The most important point is the heat resistance.

Why chosse LSR overmolding process?The main reasons for LSR overmolding are quality and performance, such as simplifying
assembly and improving sealing quality between metal/plastic substrates and silicone rubber or LSR material.The reasons may vary from application to application, but most important is lower assembly costs and the realization of device functions such as electronic sealing.
Silicone rubber, Liquid silicone(LSR) acts as a protective layer against dust, water, shock, heat and electrical shock.
