Silicone molding

SILICONE MOLDING

Alex Gianos


Silicone properties and uses

  • Silicone is heat resistant, rubber like, and an inert synthetic compound

  • Doesn’t stick to many sub straights

  • Low toxicity, thermal conductivity, and chemical reactivity

  • Ability to repel water

  • Does not support microbiological growth

  • Good electrical insulation

  • Uses: Sealants, adhesives, lubricants, medical applications, cookware and insulation

Silicone Properties and Uses


Types of silicone molding

  • 1) Liquid injection molding(LIM)- most used

  • 2) Transfer molding- custom pieces, premixed and molded, easy for rapid production

  • 3) Insert molding- allows for molding plastics into pre molded objects or metals.

Types of Silicone molding


Examples

  • Polished

  • Hotstamped

  • Plated

  • Colored

  • Clear

  • Solid

  • Thick

  • Thin

  • Textured

Capabilities


2 systems

  • Ejection system- injects the mold at high heat and pressure ( filled through suction or pushed through)

    • Material melts through frictional hear in machine

  • Clamping machine- pushes the parts together and forms the 3dimentional object from the mold

2 Systems


Companies

  • Albright Technologies

  • Vestanic

  • Peterson Molding Enterprises

  • Sil-Pro

  • DarCoid

Companies


Endless possibilities

  • Medical devices are perfect for this because they can be disposed of easily

    • Extremely clean and sanitary

  • Degradable and recycled

  • Surgeries, metal tools with plastic grips,

  • 3 ways of molding allow for intricate or simple pieces.

Endless possibilities
