Injection Mold Tooling
Injection mold design review, tooling coordination, fitting, trial samples, and production-readiness support.
- Part and mold DFM
- Core, cavity, and action review
- Mold fitting and trial support
- Tooling documentation coordination

Service overview
Tooling decisions connected to the molded part and production plan.
Injection mold tooling starts with the plastic part, expected resin, appearance requirements, projected volume, and approval process. Kewei reviews core and cavity strategy, mold actions, inserts, cooling, gate and runner concepts, ejection, and service access.
The tooling route also defines how trials are documented, which dimensions and appearance zones are inspected, and how approved corrections are controlled before production release.

Representative mold insert and guide features used to form custom plastic parts.
Key capabilities
Process planning connected to the drawing and end use.
The manufacturing route is reviewed around geometry, material behavior, critical features, appearance, inspection, and downstream assembly.
Core, cavity, and action review
Mold fitting and trial support
Tooling documentation coordination
Typical parts
Parts commonly reviewed for mold tooling.
Industries
Applications supported across engineering teams.
Materials
Material options linked to technical guidance.
Surface Finishes
Surface Finishes reviewed for material and application fit.
Tolerances and design guidance
Define what is functionally critical.
Tooling dimensions are evaluated against molded-part shrinkage, steel-safe adjustment strategy, shutoff conditions, moving actions, venting, and the inspection approach for both tool components and molded samples.
Provide the latest molded-part model, resin grade, texture, color, and appearance zones.
Identify expected production volume and any interchangeable insert strategy.
Define sample approval criteria before the first trial.
Record tool corrections and drawing revisions through controlled trial stages.
Quality assurance
Inspection planning starts with the drawing.
Inspection points are selected from the controlled drawing, functional risk, process behavior, appearance criteria, and documentation requested for the project.
Tool design and revision review
Core, cavity, action, and shutoff inspection
Fitting and trial readiness checks
Trial sample and correction record support
Manufacturing workflow
A controlled route from RFQ to shipment.
The exact route changes with process and project risk, but each stage keeps the approved drawings and requirements in view.
- 01
Mold DFM
Review part geometry, resin, shrinkage, gate, ejection, actions, and tool life expectations.
- 02
Tool manufacture and fitting
Manufacture mold components, fit actions, and verify assembly readiness.
- 03
Trial and sample review
Run trials, inspect samples, and record process or tooling corrections.
- 04
Approval and production handoff
Confirm approved changes, documentation, and production readiness.

Mold Tooling questions from engineering and sourcing teams.
What should I provide for a injection mold tooling quotation?
Send a 3D CAD file when available, a 2D drawing for critical dimensions and tolerances, material, quantity, finish, inspection, and delivery requirements. An engineer reviews the package before quotation.
What information is needed before mold design review?
Provide the latest part model and drawing, resin grade, color and texture requirements, expected quantity, critical dimensions, cosmetic zones, mating parts, and any preferred gate or parting-line restrictions.
How are tooling changes handled after a trial?
Trial findings should be documented against the current revision. Proposed steel changes, process adjustments, or part-design updates are reviewed before implementation and the next sample stage.
How is lead time determined?
Lead time depends on geometry, material availability, quantity, tooling or setup requirements, surface finishing, inspection, and delivery needs. Timing is reviewed with the quotation rather than presented as a fixed promise.
