Guangzhou S-Guangyu Machinery & Equipment Co., Ltd specializes in designing and manufacturing liquid silicone rubber (LSR) injection molding machines. Our equipment is widely used across multiple industries including medical supplies, sports equipment, automotive parts, food processing, electronics, baby products, adult products, kitchenware, and high voltage cable accessories.
LSR Dosing System Overview
An LSR dosing system is specialized equipment that precisely meters and mixes two components (A and B) of LSR material before injection into a mold. These systems are essential for achieving accurate mixing ratios and producing high-quality LSR parts.
Key Functions
Metering: Accurately measures required volumes of components A and B
Mixing: Thoroughly combines components to create homogenous mixture
Delivery: Transfers mixed LSR to injection molding machine
System Importance
Ensures precise 1:1 mixing ratio for proper curing
Maintains consistent product quality
Reduces material waste and consumption
Supports high-volume production with fast filling speeds
Cleanliness standards for medical/food applications
Equipment integration with existing systems
LSR Injection Molding Machine
Our LSR injection molding machines are specialized equipment designed to produce parts from liquid silicone rubber through liquid injection molding (LIM) processes. These machines handle the unique properties of LSR, a thermoset material requiring specific processing conditions.
Key Features
Dedicated LSR injection unit for low viscosity materials
Precision meter mixing system (typically 1:1 ratio)
Static mixer for component combination
Heated mold cavity for proper curing
Precise temperature control systems
Fast cycle times for efficient production
Advantages
Capable of complex geometries and thin-walled sections
Operates at lower injection pressures than thermoplastics
High precision and repeatability for tight tolerances
Produces parts with excellent temperature resistance
Creates components with superior material properties
