Tri-Par Die and Mold Corporation is expanding its manufacturer representative sales team.   For 60 years, Tri-Par has provided precision injection molding manufacturing services and we are looking forward to building upon this history.  If your agency has a plastic molding experience background, we are interested in speaking with you.

You can be confident of your alignment with Tri-Par because we are ISO 9001:2015 certified and we specialize in full-service precision plastic injection molding of complex parts, sealing surfaces and tight tolerances – straight molding, insert molding, two shot, over-molding, thin wall, and thick wall, experienced in a wide spectrum of materials – filled and unfilled; full part finishing, contract assembly and packaging services to meet JIT/KANBAN requirements.   We have the ability to meet a wide range of  OEM sector requirements.

Tri-Par Die and Mold Corporation offers:

  • Extensive experience working with Manufacturer Representatives – Member of MANA.
  • Currently in Expansion mode – You may contact our other reps to learn more about us.
  • Competitive commission structure


Candidate agency should demonstrate active experience selling directly into OEMs and history of working with custom plastics engineered solutions for new (and transfer) projects from concept forward.

The agency’s line card should provide complementary products to allow for sales effort opportunities without any direct conflict to Tri-Par.  We are looking for our manufacturer representative agency to work with Tri-Par on a long-term basis.  In exchange, Tri-Par will provide full sales and engineering support and offer a competitive commission plan.   This is not a direct-hire role, it is a contract and commission exclusive account-by-account role.

Available Territories on Account-by-Account basis.  North American geographic location is of interest.  Tri-Par is located in Northern Illinois.    Targeted areas are Illinois, Wisconsin, Indiana, Michigan, Missouri, Minnesota, Ohio, Iowa, Kentucky, Tennessee – Open to other states you may cover.
