LSR Moulding Types

Liquid Silicone Rubber Molding Machines
LSR is a two-component liquid material divided into A and B barrels. The two component are pumped through a static mixer by a metering pump into a precise 1:1 ratio. Because some products are colored, so they are equipped with a color pump set and a color metering part. The A+B components, additives, colors, etc. are mixed completely and then enter the plasticizing system.

Advantages of Liquid Silicone Rubber Moulding
  • Quality Stability:  Stable LSR product's sizes and designs for each batch, suit to manufacturing repeatability.
  • Short Cycle Time: About 15 seconds.
  • High Precision: Mini parting line, sizes tolerance can less +/- 0.02mm, especially for 2 shot & overmolded production.
  • Flashless Technology: No or less elastomer silicone rubber burrs.
  • Direct Injection: No or less waste.
  • Safest Manufacturing Process: Platinum cured silicone, medical & food  FDA grade silicone molded production in clean room.
  • Automated Manufacturing Systems: work like plastic injection molded by mechanical arm and assembly line.
  • Automatic Demolded: Automated Ejection.
Vertical Liquid Silica Gel Molding Machine
Vertical liquid silicone molding usually used for two-shot molding, such as for molding for combining metal & plastic parts and over-molding.
And generally, 2 lower plates are required for improving production efficiency.
Horizontal Liquid Silica Gel Molding Machine
For horizontal liquid silicone molding machine, the LSR products can drop down automatically. So most automatic production will choose horizontal liquid moulding machine.
