Insert Molding & Overmolding Services
Insert molding and overmolding for parts that integrate metal hardware, a rigid substrate, a soft surface, sealing, insulation, or another material function.

Choose the process from the interface
Insert molding places a component in the cavity before resin is injected around it. Overmolding adds material over a separate substrate. Selection starts with the required function, material relationship, production sequence, and test method.
Control inserts and substrates
DFM should define orientation, location, support, shutoffs, gates, vents, flash, heat exposure, contamination, and detection of missing or misplaced components.
- Specify insert or substrate drawings
- Define loading and detection
- Agree on interface and cosmetic criteria
Validate material and geometry together
Grade-level compatibility, surface condition, wall geometry, mechanical interlocks, and service exposure influence the finished interface. Production-representative parts should be tested in the intended assembly.
Plan production evidence
Agree on component traceability, process records, insert detection, dimensions, appearance, functional tests, and reaction plans before production approval.
The same engineering path, adapted to your program.
See how analysis, tooling, and process learning stay connected from review through production. Findings and acceptance criteria are defined for each program.

Review geometry, material, gates, ejection, and tooling risks before steel is cut.

LongTeam injection mold tooling, built to carry engineering decisions into production.

Use dimensional and process data to identify variation and guide engineering decisions.
