Our Liquid Silicone Rubber (LSR) Injection Molding Process
LSR is a two-part material, typically mixed in precise ratios before injection. The base liquid silicone and curing agent are blended to ensure uniform consistency and proper curing.
Custom molds are designed to the required specifications and preheated to the optimal temperature to promote proper material flow and curing during injection.
The prepared LSR is injected into the mold cavity under high pressure using a precisely controlled injection system. The material's low viscosity ensures it fills complex mold shapes accurately.
Once injected, the LSR material is cured in the mold, typically using heat or ultraviolet light. The curing process hardens the material, ensuring its strength and stability.
After curing, the mold is opened, and the molded LSR parts are carefully removed. The parts maintenir tight tolerances and intricate details as requis.
The molded parts may undergo additional processes such as trimming, cleaning, or surface finishing. Each part is inspected for quality, ensuring it meets strict standards for performance and functionality.
