Process

From drawing review to approved mold and production delivery.

A custom mold project needs clear engineering communication at every step. This workflow helps buyers understand how Shengqi handles injection molds and SMC/BMC/DMC/FRP compression molds from inquiry to delivery.

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.

What we check and do

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.

What we check and do

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.

Output

Mold design plan
Engineering review
Quotation confirmation

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.

What we check and do

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.

Output

Machined mold components
Assembled mold
Progress updates

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.

What we check and do

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.

Output

Trial samples
Inspection feedback
Adjustment list

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.

What we check and do

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.

Output

Adjusted mold
Approved samples
Final confirmation

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.

What we check and do

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.

Output

Export-ready mold
Production parts if required
Delivery support

Before quotation

Prepare drawings, sample photos, material requirements and expected quantity.

The more complete the information, the more accurate the mold plan and quote. If some details are missing, Shengqi can review the application first and help confirm the right molding direction.
