Silicone Molding For Product Design

Why You Should Download

Soft components are an ubiquitous part of most commercial goods, from rubbery feet on a laptop to the ergonomic grip on a pair of scissors. Rubbery materials like polyurethanes, silicones, neoprene, and latex enable product applications from roofing materials to medical devices.

Casting of silicones specifically allows us to expand the properties of 3D printed parts to include bendable and stretchable components using materials readily accessible from hardware stores, art and jewelry supply resellers, and other common retailers.

This report includes case studies from companies OXO, Tinta Crayons, and Dame Products, illustrating three different implementations of silicone molding for product design and manufacturing: compression molding, two-stage casting and overmolding.

Throughout this white paper, you’ll learn about:

  • Selecting silicone for your application.
  • How to use a compression mold for gasket prototyping.
  • The best way to replicate a 3D printed master with a flat side.
  • How to encapsulate hardware using overmolding.
  • Best practices for designing critical features of 3D printed molds.
