Custom rubber molding at LeRoy Tool & Die begins up front with our customers in the form of project management and in-house collaborative engineering support to identify the correct material and ensure the optimal design of each part.

From there a member of engineering team uses NX to design tooling that delivers the best overall value taking into consideration:

  • Customer Specific Requirements (CSR’s)
  • Annual usage
  • Application
  • Tooling budget
  • Demolding
  • Cycle times
  • Desired part appearance
  • Secondary operations
