Injection molding · Erie, Pennsylvania

Every part starts as a flow path.

Custom injection molding, overmolding, insert molding, prototyping and assembly — run from one shop floor in Erie, Pennsylvania.

01 Material & prototype

Flow stage one

Read the material before you cut steel.

Flow starts with resin. Wall thickness, gate location and shrink are read against your geometry, and prototypes are molded so they behave like the production part.

01

Resin selection

Material matched to the part's load, temperature and surface requirement.
02

Prototype tooling

A first tool proves the geometry and the gate position before production tooling is cut.
03

Gate and fill review

Gate position, fill pattern and weld lines read against the drawing before the first shot.
04

Design feedback

Wall sections, draft and radii returned with comments before release to tooling.

Stage 01 output — geometry, gate position and resin confirmed before tooling.

02 Tooling & custom molding

Flow stage two

Custom injection molding, tool to press.

Tools are built to your part, not to a catalogue. Cavities are laid out for balanced fill, then set and run on the press.

Tool design and build

Cavity layout, gating and cooling designed around the part geometry.

Single and multi-cavity tooling

From a single-cavity prototype tool through multi-cavity production tooling.

Process setup

Shot size, hold pressure and cooling time established with the tool.

03 Secondary flow paths

Flow stage three

Two materials. One part.

Once the base part fills cleanly, a second shot or a placed component extends it. Overmolding and insert molding run as separate flow paths into the same tool.

Secondary path A — Overmolding

A second shot bonds to the first.

A soft or coloured material is molded directly onto the rigid substrate, so grip, seal or finish is part of the part — not a separate piece added later.

Secondary path B — Insert molding

Metal placed before the shot.

Threads, bushings and contacts are loaded into the cavity and molded in place. The insert becomes part of the molding instead of a later operation.

Where it fits

Overmolding and insert molding are decided at the design stage — substrate, second shot and tool layout have to agree before the cavity is cut.

04 Final packed state

Flow stage four

Assembly is the packed state.

Molding finishes the part. Assembly finishes the job. Components, inserts and hardware are joined to the assembly drawing and checked before anything leaves the bench.

Mold and inspect

Parts come off the press and are checked against the drawing.

Place inserts and hardware

Threads, bushings and mating components are set into the molded parts.

Join the sub-assembly

Components are fitted and joined to the assembly drawing.

Pack from Erie

Finished assemblies are packed and staged for shipment.
