Requirement Review

Drawing or Sample Review

We start by reviewing the product drawing, sample photo or physical sample to understand the application, material direction, size, tolerance and expected production volume.

Engineering Review

Check 2D/3D drawings, product photos, sample dimensions and functional requirements.
Review the application environment, material options and possible molding risks.
Confirm whether the project is suitable for injection molding or SMC/BMC/DMC/FRP compression molding.
Clarify missing information before quotation so the mold plan is realistic.

Engineering Plan

Mold Design and Engineering Plan

After the requirement is clear, the engineering team prepares a mold solution covering structure, cavities, material flow, parting line, ejection, cooling and production feasibility.

Engineering Review

Create or review mold structure based on the product design and production target.
Plan cavity layout, gate position, parting surface, inserts, sliders and ejection method.
For compression molds, review material charging, pressure, venting and forming stability.
Communicate key engineering decisions with the customer before tooling starts.

Tooling Stage

Tooling and Machining

Once the mold plan is approved, the mold enters machining and assembly. This stage turns the engineering plan into a real production tool.

Engineering Review

Prepare steel/material, machining schedule and mold components according to the approved plan.
Carry out CNC machining, EDM, drilling, polishing, fitting and mold assembly.
Control key dimensions and surfaces that affect product quality and mold life.
Track progress and keep project communication clear during mold manufacturing.

Trial and Check

Trial Molding and Inspection

The first trial verifies whether the mold can produce stable parts. Samples are checked for appearance, dimension, structure and molding performance.

Engineering Review

Run initial mold trial with suitable molding parameters and material conditions.
Inspect sample appearance, dimensions, assembly fit, deformation and surface quality.
Record molding problems such as flash, shrinkage, short shot, warpage or difficult demolding.
Share sample feedback and adjustment suggestions with the customer.

Approval Stage

Mold Adjustment and Approval

Based on trial results and customer feedback, the mold is adjusted until the sample meets the agreed production and quality requirements.

Engineering Review

Modify mold details according to trial molding data and sample inspection results.
Optimize dimensions, surface, venting, cooling, ejection or compression forming stability when needed.
Run follow-up trials to confirm that problems are solved.
Obtain sample approval before final delivery or production.

Delivery Stage

Production or Export Delivery

After approval, the mold can be exported to the customer or used for molded product production when the customer needs high-volume supply.

Engineering Review

Prepare the mold for export packing, documentation and shipping if the customer receives the tool.
Support molded product production when the project requires finished parts instead of only mold delivery.
Confirm packaging, quantity, delivery schedule and export requirements.
Provide follow-up support for mold use, maintenance or future product updates.
