In-House Tooling Support

Leech offers customers a one-stop solution for tooling support. Having streamlined in-house tooling operations reduces the need to outsource operations, producing the following results for our customers:

  • More efficient speed-to-market
  • Significant cost savings on shipping to multiple manufacturers
  • Greater quality tools
  • Room for flexibility, with customers only needing to reach out to a single tool maker to make any necessary adjustments

Expertise in Injection Molding
