The Better 615A Vertical LSR Injection Molding Machine is specifically engineered to overcome the unique production challenges of children's teether sets. Unlike simple flat gaskets or thin-film nipples, teethers are three-dimensional, thick-walled oral care products that must endure aggressive chewing, frequent boiling sterilization, and exposure to teething gels - all while maintaining a flawless, non-porous surface that resists bacterial colonization. Our machine delivers the perfect balance of filling speed, packing pressure, and thermal control to transform complex molds into profitable, high-yield production lines.

Silicone rubber is a high-performance synthetic elastomer composed of silicone and other molecules (e.g., carbon, hydrogen, and oxygen). It is characterized by high viscosity and elasticity, as well as superior abrasion resistance, chemical stability, insulating properties, temperature resistance, and weatherability compared to organic rubber.

• Operating temperature range: -100°C to 350°C (depending on exposure duration)
• Weatherability: Resistant to wind, rain, UV radiation, and ozone
• Moisture resistance: 1% water absorption in various water temperatures
• Steam resistance: Indefinite resistance to unpressurized steam
• Chemical resistance: Resistant to oils, solvents, polar organic compounds, and diluted acids/alkalis
• Electrical insulation: 1TΩ*m-100TΩ*m across wide temperature and frequency ranges

Silicone rubber varies by viscosity and processing method:

• Solid Silicone Rubber (HTV): Long polymer chains processed by conventional methods
• Liquid Silicone Rubber (LSR): Short polymer chains requiring specialized injection molding
• Room Temperature Vulcanized (RTV) Rubber: Used for sealing, encapsulation, and potting applications

Silicone rubber is used across multiple industries including:

• Aerospace (space suit components)
• Automotive (gaskets and seals)
• Medical (instrument components)
• Food processing (molds)
• Electronics (adhesives and encapsulants)
