What Are You Trying to Manufacture?
I Need an Injection Mold
Build a mold in China for use in your own molding facility.
We manufacture and export tooling around your press, mold-base standard, fitting requirements, resin, and expected tool life.
- DME, HASCO or agreed component standards;
- metric or imperial interfaces;
- compatible water and electrical connections;
- lifting points and mold locks;
- spare wear components;
- test-molding documentation;
I Need Molded Plastic Parts
We build the mold, retain and maintain it, and produce parts as required.
Suitable for companies that want a long-term production supplier rather than only a tool builder.
- resin sourcing and verification;
- color matching;
- molding-process development;
- insert molding;
- robotic operation to reduce cost;
- secondary operations;
- inspection and batch documentation;
I Need a Complete Product
Plastic is often only one part of the product. We can add CNC-machined parts, stamped brackets, die-cast components, aluminum extrusions, fasteners, wiring, electronics, labels and packaging.
- NDA & IP protection;
- incoming material inspection;
- semi-automatic fixtures for fitting and assembly;
- functional testing;
- labeling and export packaging.
Historical Mold Cost Evidence
See Real Mold Examples from $1,700 to $33,000
Compare mold structure, cavity count and downloadable product and mold STEP files. Historical prices are reference points; current costs depend on the final design, steel, life target and production plan.
Injection-Molding Capability for More Demanding Parts
Some components require more than a conventional single-material mold. We support specialized molding projects in which part size, contamination control, material combinations, surface quality or embedded components create additional engineering requirements.

Plastic Manufacturing Is Not Limited to Injection Molding
Injection molding fits many programs, but part size, quantity, geometry and budget sometimes point to a different process. Our engineers recommend the route that makes economic sense—not just an injection mold.
Liquid Silicone Rubber Molding
Flexible, heat-resistant components, seals and protective products.

Plastic Welding

Your Product Is More Than a Plastic Part
A plastic molding supplier may be able to produce the enclosure but leave you to coordinate the rest of the bill of materials.
CSMFG can take responsibility for the larger manufacturing problem.
Our teams can combine injection-molded parts with metal components, purchased hardware, electronics, surface treatments, printed graphics and packaging. This reduces supplier handoffs, tolerance disputes, assembly problems and delays between separate factories.
For Industrial OEMs and Professional Purchasing Teams
Quality Is a Managed Process, Not a Final Inspection
Corporate buyers need more than a good sample.
They need repeatable production, controlled changes, traceable materials, documented inspection and a clear owner when a problem occurs.
Controlled from DFM through sample approval
Each qualified project has a commercial contact, project engineer and quality owner.
- DFM before steel cutting
- T1 samples with dimensional report
- T2/T3 validation rounds when corrections or further approval are required
- Traceable materials and controlled changes
Built for International Projects
CSMFG helps international companies manage custom manufacturing in China through engineering communication, supplier coordination and quality control.
Founder Edward Fan is an MIT-trained engineer with experience across product development, manufacturing and supply-chain management.

How much does an injection mold cost?
A basic mold for a small, relatively simple component may cost several thousand dollars. Larger molds, multi-cavity molds, hot-runner molds and tools with sliders, lifters, unscrewing mechanisms or high cosmetic requirements can cost substantially more. Use our mold price calculator for preliminary planning.
What design discussions are needed?
We issue a DFM report and can discuss parting-line location, ejection points, critical dimensions, cosmetic expectations and your other key requirements before steel is cut.
Do I own the injection mold?
Customer-funded molds are customer-owned under the agreed purchase terms. Ownership, storage, maintenance and transfer conditions should be stated in the quotation and order documents.
Can you build a mold and ship it to our factory?
Yes. Export molds can be built around agreed mold-base, component, water-fitting, electrical, press and safety requirements.
What if injection molding is not the right process?
We also support extrusion, blow molding, silicone molding, vacuum forming, thick-sheet thermoforming, compression molding and plastic welding.
Can you manufacture the metal parts too?
Yes. Projects can include stamped, machined, fabricated, extruded, cast or purchased metal components in addition to the plastic parts. We can also perform assembly, inspection and packaging.
Start with a CAD File, Sample or Product Idea
Tell us what you are trying to manufacture and how many units you expect to need. Our team will review the part, identify the likely production process, explain the major tooling and quality considerations, and prepare the next engineering step.
Accepted formats: STEP, STP, SLDPRT, X_T, IGES, DWG, DXF, PDF, ZIP and common image formats.
An engineer or project specialist will review the submission and respond within one business day. Formal quotation time depends on project complexity.
