KEY SERVICES OF SILICONE & RUBBER PRODUCTS

Liquid Injection Molding (LIM) and Transfer Molding are preferred processes for manufacturing solid silicone rubber items used in a wide range of applications such as medical equipment, watersports, gas masks, military gear, waterproof device cases, shock absorption, 3C products and much more.

Materials

Shin Etsu / Dow Corning / GE Silicones

Advantages & Applications

  • Low viscosity and lower injection pressure, good for silicon molding
  • Good chemical stability and environmental protection
  • High dimensional accuracy
  • It produces high quality parts without secondary finishing and
  • allows much shorter production cycles than other processes.
  • Over-molding together with hard plastic frame (PC, ABS, etc.) for waterproof devices, shock proofing, shielding, etc.
  • Very thin wall design (0.25mm thick around) for silicone to adhere on plastic housing (rib) to meet the demand of low profile product design.
  • Waterproof feature can be secured by the combination of soft rubber contacts and with constant pressure provided by hard plastic housing (rib).
