Tool Engineering

Successful Liquid Silicone Rubber (LSR) processing demands a high degree of workmanship and precision in both tool design and tool manufacturing. G & F Medical addresses the needs by:

  • Working with experienced Liquid Silicone Rubber (LSR) tool makers in the US and Europe
  • Engineering high quality tools for both low volume and high volume production
  • Scrapless Liquid Silicone Rubber (LSR) cold runner technology at an affordable cost: in return customers receive high quality parts at much lower unit part cost.
  • G & F Medical is fully competent to design and automate a molding operation.
  • Customized fixture design

How cold runner technology can be beneficial in LSR molding:

  • Direct injection reduces material waste in runners and sprues
  • In multi-cavity tooling, material flow in each cavity can be balanced.
  • Balanced fill in multi-cavity tools results in less cavity to cavity variation (e.g. functional and performance characteristics of molded parts)
  • Less pressure drop in the runner system
  • Easy to automate the molding operation

Benefits cited above deliver high yield, repeatability, greater consistency, quick cycle time and low cost production.
