Wall thickness, ribs, bosses and undercuts
We look for common geometry risks that may affect filling, ejection, sink marks, warpage or tooling complexity.
Free DFM Review For Injection Mold Projects
Email your 3D CAD files and project basics. TEC-SHINE engineers will review part design, tooling feasibility, material, tolerance, surface finish and production risks before you commit to mold manufacturing.
24-48h
Engineering response after complete CAD and project details.
DFM + Moldflow
Feedback on moldability, cooling, material and risk.
Tooling + Molding
One workflow from mold design to injection molding.
Since 2005
Shenzhen mold manufacturing and export experience.
What We Check Before Quotation
DFM is not a generic report. It is a focused engineering review that helps identify issues before tooling, sampling and mass production.
Best for plastic parts, injection mold projects, tooling transfer checks, product redesigns and production cost review.
Parting line, gate, slider and lifter review
We identify the likely mold structure and flag features that can raise cost, lead time or maintenance risk.
Material, tolerance and surface finish
We connect part requirements with practical injection molding, secondary operation and inspection needs.
How The Free DFM Process Works
Keep the first step simple. Send engineering files and quotation basics, then we can respond with review notes and the missing items needed for pricing.
Send CAD And Project Basics
Share 3D CAD files, 2D drawings when available, material, quantity, surface finish, timeline and any existing issue.
Engineer Reviews Feasibility
Our team checks design, mold structure, molding risk, process route and missing quotation information.
Receive Notes And RFQ Direction
You receive practical DFM notes and the next-step list required for a formal mold or molding quotation.

Need A Formal Quotation?
After the DFM review, we can quote mold design, mold manufacturing, sampling, injection molding, secondary processing and assembly based on confirmed files and project requirements.
Request QuotationFree DFM is a first-step engineering review
It is designed to identify obvious moldability and quotation risks. It is not a full mold design package, certified simulation report or production approval document.
