Our Capabilities

Molding, tooling, and everything between.

Five capabilities under one roof in Plymouth, Michigan — so the part, the mold, and the tooling that makes it are all designed against the same requirement.

Engineering Support

Engineering Support

Not sure how to get from a requirement to a finished part? We work directly with your engineers to design a durable, easy-to-install component that integrates with the tooling and process you already run.

  • Direct: your engineers talk to ours — not to an account manager relaying messages.
  • Integration: designed around your existing tooling, fixtures, and assembly steps.
  • Optimization: process review that takes cost and cycle time out before production starts.
Custom Injection Molding

Custom Injection Molding

Precision injection molding for specialized plastic components across automotive, industrial, agriculture, and consumer goods — with tight tolerances and repeatable shot-to-shot results.

  • Material: resin chosen for the heat, chemical exposure, and handling the part actually sees.
  • Process: insert molding and over molding handled in-house, not shipped to a second supplier.
  • Volume: hundreds to hundreds of thousands, validated before the run leaves the floor.
Part Design

Part Design

Collaborative engineering that turns your concept into a production-ready component. We optimize designs for manufacturability, durability, and cost-effective injection molding.

  • Manufacturability: draft, wall thickness, and gating resolved before tooling is ever quoted.
  • Durability: geometry and material specified for the load and the environment.
  • Cost: design decisions weighed against cost per part, not just against the print.
Rapid Prototyping

Rapid Prototyping

Validate your design before production. Fast-turnaround prototypes let you evaluate fit, function, and performance while reducing development time and costly tooling revisions.

  • Proof: hold the part, check the fit, test the function before anything is committed.
  • Iteration: revisions in days — not after a cavity has already been cut.
  • Handoff: the approved prototype becomes the production print, with no redesign in between.
Tooling

Tooling

We work closely with our customers to optimize tooling for maximum efficiency. From cold runner to hot runner designs, pneumatic and sequential valve gating, and prototype tooling through to production tooling, we design and build to meet and exceed your expectations.

  • Scope: prototype and production tooling, both built from the same design intent.
  • Gating: cold runner, hot runner, pneumatic, and sequential valve gating configurations.
  • Efficiency: cycle time and maintenance designed in from the start, not patched later.
Value-Added Assemblies

Value-Added Assemblies

Molding is rarely the last step. Assembly, insert placement, and finishing are handled here alongside the press, so a component leaves ready for your line instead of being routed to another supplier first.

  • Assembly: multi-part components put together here rather than shipped out for it.
  • Inserts: threaded inserts, hardware, and over-moulded components placed in process.
  • Finishing: packing and presorting to whatever the receiving bench actually needs.
