Product Description

Custom Liquid Silicone Injection Molding for Liquid Silicone Rubber

Liquid Silicone Injection Molding, also known as LSR Molding, Liquid Silicon Rubber Molding and silicon injection molding, which is an injection machine to produce pliable, durable and high precision LSR medical accessories, food grade Liquid silicone products electronic parts and automobile parts.
Liquid Silicone Injection Molding for LSR Silicone Rubber Mould Parts
Better Silicone is a professional liquid silicone rubber(LSR) injection molding manufacturer & Liquid injection molded factory, which not only make LSR mold-making and Silicone injection molded prodction, but also offer LSR molded products modability& manufacturability analysis, cold runner systems(Shut off valve) liquid injection mold design service etc.

Liquid Injection Molding Main Parts:
LSR dosage system, which includes two raw material tubes
Control system(Static Mixer)
Heating Channel and Cooling Channel

LSR Injection Molding: Vertical and Horizontal.
Horizontal moulding machine: with horizontal code mold, easy to achieve automatic production.Horizontal direct pressure clamping ensures the clamping force be steady and equally distribution.
Vertical silicon injection molding machine: with vertical mold, standing frame mold, requires manual pick and place products, such as Insert molding. Vertical clamping, vertical injection. Space-saving compact design makes the product take-out more convenient.

Liquid Injection Molding advantages:

 
High Precision Small Parting Line, No & Less silicone flashing, even 2-shots & overmolded with plastic or metal etc.
Safer Platinum Cured, more safe FDA silicone.
High Efficiency Short Cycles, espcially, for mass manufacture.
Other advantages like high purity, more transparency, highly tensile strength, highly tear resistance etc.

Liquid Injection Molding flow/sulfur analysis:
1) The vulcanization chemistry of liquid silicone rubber requires a certain reaction time.
2) Ideal flow, within diameter 2mm, 170cm, and flow distance is more than 100cm.
3) Small thickness 1/1000mm
4) Excessive mold temperatures will cause vulcanization, which cause the flow to be blocked.
5) Laminar flow can avoid bubbles
6) High-speed injection will cause turbulence
7) The viscosity of the material will change the flow pattern
8) Turbulence leads to white spots.

So,in the process of molding making, we need to pay attention to the following aspects:
  1. using a small plastic injection port to avoid turbulence and spray.
  2. Use needle or wing rubber injection
  3. Use a T-shape guide bolt rather than a cylindrical guide bolt
  4. use an air gun to remove products from the mold
  5. Add an insulation/board.
  6. Use toluene and xylene instead of rust inhibitor/oils which contains inhibitors.
