Start With the Information That Shapes the Project
Send CAD files or drawings, material requirements, estimated quantity, critical dimensions and target timing. We will review the information needed to plan the next manufacturing step.
START YOUR RFQ
Send the Basics. We Will Review the Details.
A work email and a short project description are enough to start. Add material, quantity or drawings when they are available.

A Practical Project Process for Custom Parts
A molding project is easier to manage when the engineering, tooling, trial and production decisions are connected from the beginning. This page explains the practical project process for custom plastic parts.
For production-ready OEM parts, see our Custom Injection Molding service. Projects requiring new tooling can start with Plastic Mold Engineering and Manufacturing.
How an Injection Molding Project Moves Forward
The project route is planned around the actual part, material, quantity, critical requirements and intended production stage.
We check 3D/2D files, application, material, tolerance and expected quantity.
Draft, wall thickness, ribs, undercuts, gates and appearance risks are reviewed.
Mold steel, cavity count, runner type, texture and mold life target are discussed.
CNC, EDM, polishing, fitting and assembly are controlled through the mold build.
Trial samples are checked for dimensions, function, appearance and process stability.
Approved process settings, inspection records and packing requirements support shipment.
What to Prepare Before Requesting a Quote

Drawing-Based Inspection and Export Packing
| Stage | What We Check |
|---|---|
| Before Tooling | DFM risks, material suitability, critical dimensions, mold structure and steel selection. |
| Mold Trial | Short shots, flash, sink marks, weld lines, warpage, gate vestige and ejection marks. |
| Production | Process settings, first article samples, in-process inspection, appearance and packing. |
| Shipment | Quantity, labeling, protective packaging and export packing requirements. |
Injection Molding Project Process FAQ
What files should I send for quotation?
STEP, STP, IGES, X_T or SLDPRT files are preferred. PDF, DWG, DXF and product photos help us understand tolerances, surfaces and assembly requirements.
When can DFM analysis be planned?
DFM analysis is normally planned within 1–3 working days after complete project information is received. The review helps identify the information that should be confirmed before tooling and production move forward.
What production planning range can be considered?
Our production planning range includes 50T–350T injection machines and tooling support for 1–32 cavity molds. Final planning depends on the part, material and expected output.
