Custom mold tooling · China → United States

Custom injection mold tooling for production-ready plastic parts.

Send a part file, drawing, sample, or project brief. We review fit first, then clarify DFM risks, tooling assumptions, timing, and the path to a reliable mold quotation.

  • First human response targeted within 24 hours
  • DFM review and final quotation timing confirmed after scope review
  • Files optional for the first contact

Project qualification

Tooling programs with a clear part, production plan, and decision path.

We confirm project fit before pricing. If a program needs compliance, tolerance, cavity, or validation capabilities we cannot demonstrate, we say so before quotation work begins.

Good starting point

Projects we want to review

  • Custom plastic parts for consumer, household, industrial, construction, or agricultural applications
  • General automotive interior, exterior, or under-hood components reviewed case by case
  • Programs with a 3D model, 2D drawing, sample, photos, or a clear part specification
  • Company projects with an expected mold budget from US$5,000 or a defined production plan
Needs a different supplier or more evidence

Projects outside the first-stage scope

  • Medical devices, aerospace parts, or safety-critical components requiring special compliance
  • Automotive Tier-1 or OEM programs with approvals that are not confirmed before quotation
  • Extreme tolerance, ultra-thin-wall, or high-cavity programs outside demonstrated capability
  • Commodity mold-base trading, student requests, or idea-only inquiries without usable part information

Factory proof

Tooling, trial, and export work shown with real workshop evidence.

Project-specific specifications are confirmed from the buyer's data. We do not replace engineering evidence with unsupported certifications, logos, or generic promises.

Anonymous technical examples

Three technical examples buyers can review before sending an RFQ.

Customer identities stay confidential. Each example shows the available part context, tooling scope, engineering question, and supporting reference material. It does not claim a completed customer project or a measured result.

Tooling process

From part information to mold trial and export handoff.

  1. 01

    Part and RFQ review

    We check the part file or brief, resin, annual volume, cavity direction, machine information, timing, and delivery destination.

  2. 02

    Initial DFM and quote direction

    We identify manufacturability risks, missing inputs, mold assumptions, and the next step needed for a reliable quotation.

  3. 03

    Mold design and manufacturing

    Approved programs move through design, machining, EDM, fitting, and documented engineering communication.

  4. 04

    Trial and correction

    Trial parts are reviewed against the agreed project requirements before corrections and approval planning.

  5. 05

    Export handoff

    Packing, included documents, destination, and logistics responsibilities are confirmed before shipment.

Free initial review

Share enough information to replace assumptions with an engineering conversation.

You do not need every field or file on day one. We will confirm missing information and whether the program fits before a formal quotation.

  • 3D CAD, 2D drawing, sample, or clear photos
  • Part resin and any critical surface or tolerance requirements
  • Annual volume and preferred cavity count
  • Available injection machine or clamp tonnage
  • Target date and mold delivery destination
  • Known validation, trial, or export-document requirements

Frequently asked questions

Before you send the project.

Can you review a project without a 3D CAD file?

Yes. You can start with a 2D drawing, sample, clear photos, or a detailed part brief. A reliable final quotation may require additional project data.

Is the initial DFM and quotation review free?

Yes, for a real company project with enough part information to review. Complex simulation, detailed mold design, or formal validation work is scoped separately.

How quickly will you respond?

We target a first human response within 24 hours. We will confirm any information needed for DFM review or a final quotation. Complex formal quotations can take longer.

Do you only export molds, or can you also mold parts?

Custom mold design, manufacturing, trials, and export are the primary scope. Trial molding, pilot quantities, and ongoing injection molding can be reviewed as supporting services.

Does the quotation include delivery to the United States?

It depends on the agreed scope. The quotation should state the delivery destination, trade terms, packing, included documents, and responsibility for freight and import.

Do you accept every injection mold project?

No. We first confirm that the part complexity, compliance needs, tooling scope, and delivery requirements fit our demonstrated capabilities.

Next step

Send the available part information. We will confirm project fit before quotation.
