Wall thickness, ribs, bosses and undercuts
We look for common geometry risks that may affect filling, ejection, sink marks, warpage or tooling complexity.
Get A Quote For Injection Mold Projects
Upload your 3D CAD files and quote basics. Tec-Shine engineers will review part design, tooling feasibility, material, tolerance, surface finish and production risks before formal quotation and mold manufacturing.
Within 48 hours
Free initial DFM feedback after complete CAD and project details. Formal quotation timing is confirmed separately.
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 Quote Path Works
Keep the first step simple. Upload engineering files and quotation basics, then we can respond with DFM notes and the missing items needed for pricing.
Upload 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 DFM Notes And Quote Direction
You receive practical DFM notes and the next-step list required for a formal mold or molding quotation.
FAQ
Free DFM Review: Common Questions
What does the free DFM review check?
Our engineers review part design (wall thickness, ribs, bosses and undercuts), tooling risk (parting line, gate, slider and lifter) and production fit (material, tolerance and surface finish), then send DFM notes and the items still needed for a formal quotation.
How fast will I receive DFM feedback?
Free initial DFM feedback is sent within 48 hours after complete CAD and project details are received. Formal quotation timing is confirmed separately.
Is the free DFM review a full mold design or simulation report?
No. Free DFM is a first-step engineering review to identify obvious moldability and quotation risks. It is not a full mold design package, certified simulation report or production approval document. Moldflow analysis is offered by project scope, and its timing is confirmed per project.
Which files can I upload?
Up to 10 files, 60 MB per file and 120 MB per request. Supported formats: STEP, STP, IGS, IGES, X_T, X-B, STL, SLDPRT, ZIP, RAR, 7Z, PDF, DWG, DXF, JPG, JPEG and PNG. You can also send an initial inquiry without attachments.
Can we sign an NDA before sharing CAD files?
Yes. An NDA can be arranged before confidential CAD files are reviewed. See NDA and confidential CAD handling for how uploads are stored and how to request deletion.
What should I include with my request?
3D CAD files, 2D drawings when available, material, quantity, surface finish, target timeline and any existing issue. Critical tolerances, appearance zones, assembly interfaces and test requirements also help the review.
Which mold types does Tec-Shine build?
New custom injection molds, including complex tooling with sliders, lifters and other side actions, high-precision molds, insert molding tools, multi-cavity molds, two-shot molds, unscrewing molds and gas-assist molds. Tec-Shine does not currently take on LSR (liquid silicone rubber) mold projects.
Which quality certifications does Tec-Shine hold?
Tec-Shine holds two certificates. IATF 16949:2016 (certificate number CB02681, IATF registration 0618468, issued by TÜV Saarland Certification GmbH, valid from 21 October 2026 to 20 October 2029) covers the manufacture of injection molding parts, with a permitted exclusion for clause 8.3, product design and development. ISO 9001:2015 (certificate number F04326Q00353R502) covers the production and sales of plastic molds and metal molds.
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.
