LSR Liquid Silicone Rubber Injection Machine

LSR liquid silicone has a wide range of uses. We contact many things in daily life, such as baby pacifiers, coasters, medical supplies, silicone mobile phone cases, etc. It is widely used as a coating and potting material for moisture-proof, consignment, and insulation of electronic components in the electronics industry. It protects electronic components and assemblies from dust, moisture, shock, and insulation.

LSR Machine Application
