LSR/LSM Injection Molding

Organosilicone known as Silicone, it is a type of molecular chain and a non-breakable Polysiloxane that it's a silicon atom combined with oxygen atom.

Silicone has various kinds of material、unique functions and wide range of uses. It's an indispensable chemical materials that also call 「technology development catalyst」. As shown below is material classification.

Silicone Material Classification

FORESHOT has LSR/LSM Liquid Silicone Injection Molding technology and  offers variety types of mold to satisfy different demands, such as V-Cut without flash molding type and precision Cold Runner type.

The method of Liquid Silicone injection molding is injection molding after mixing A, B liquids,as shown below.

LSR Injection Molding

LSR Injection Molding Process

LSR is injection molding with the liquid silicone,although it's a high temperature hardening silicone but it has a lower viscosity than HTV and other elastomers.

LSR form is liquid, so it can be supplied to the injection molding machine continuously, thereby making product automatically formed.

Therefore, it not only improve production efficiency, but also has excellent physical properties, as shown below.

Liquid Silicone Injection Molding Process


  • High Temp Resistance: Outstanding material property in the condition of high temperature (over 200°C) for long time.
  • Low Temp Resistance: Outstanding flexibility in the condition of low temperature (-70°C).
  • Low Compression Set: Possible to be used for application such as sealing and gasket due to outstanding compressed permanent strain.
  • Chemical Resistance: Outstanding oil resistance, solvent resistance and chemical resistance, aniline, alcohol or alkali cannot be invaded.
  • Electric Property: Having hydrophobic for water and excellent electric insulation.


  • LSR/LSM Injection Molding could be applied in Computers / Communications / Consumer Electronics: Ear Plugs, Smart Watch Band, Wristband, Medical Products.

    Insert Injection Molding could be called Insert Molding or Over Molding, which a sole part is formed using two or more different materials in combination. In Insert injection Molding can either be incorporated at the time of the molding process or can be inserted as post molding operation.Especially, if properly selected two kinds of material, it will obtain a strong bonding of the molded part. Therefore, the used of primers or adhesive was no longer required to achieve an optimum bond between two materials.This process of insert injection molding results in a strong bonded and integrated assembly with plastic encapsulated inserts.Insert molding made from the following material :Ceramic、Plastic、Metal and The substance that can withstand the high temperature of injection molding process.
