Liquid silicone injection molding, also known as LSR injection molding, silicone injection molding, or liquid silicone molds, involves loading two liquid materials, A and B, into the machine, fully automating the entire process from mixing to molding. While simplifying the process and shortening processing time, it significantly increases production capacity and reduces labor costs, resulting in excellent economic efficiency.
It conveniently produces high-quality products. Furthermore, leveraging the various properties of liquid silicone rubber, it is widely used in various industries, including electrical, electronics, automotive, and food.
Liquid silicone rubber (LSR) is a popular silicone product among consumers and manufacturers. It offers excellent elasticity, water and moisture resistance, and resistance to corrosion from various chemicals, including acids and alkalis, making it a viable alternative to plastics in everyday products.
Pbear provides a variety of efficient, stable, and energy-saving molding solutions for various industries. Our LSR injection molding machines are specifically designed for liquid silicone rubber molding. We offer turnkey solutions, including factory layout recommendations, silicone molding machines, LSR molds, LSR batching machines, electrical testing equipment, materials, production training, and more. Buyers can enjoy a one-stop shopping experience, saving significant time, effort, and costs. Most importantly, we provide the most professional service, ensuring rapid success for new projects.
Injecting LSR into a hot-runner mold to create silicone products achieves one-shot molding, minimizes waste, and allows for automation.
LSR consists of two components, A and B. These components are mixed in a 1:1 ratio using a metering device, then thoroughly mixed in a static mixer before being injected into the injection molding barrel.
