An Extension of Your Toolroom for Made-to-Print Tooling Components
SSP (Dongguan Shuangshun Precision Tooling Co., Ltd.) has designed and built progressive dies, injection molds and their replacement components in Humen, Dongguan since 2008. The engineers who build our complete tools also make your spare parts, so every punch clearance, pilot fit and core insert is made for how it has to work inside the tool, not only for what the drawing shows.
Buyers use us to cut downtime on production tooling, to second-source worn components and to stock interchangeable spares for dies and molds built anywhere in the world. Looking for a catalog-standard component instead? See our standard tooling spare parts to DIN, ISO, HASCO and MISUMI dimensions.

- Mold shops
- OEM maintenance teams
- Tooling distributors
Made to print, or from your worn part
Send 2D or 3D files, or ship us the worn component. We measure it, draw it and send the drawing for your approval before any steel is cut.

Each quote comes with DFM notes on tolerances, grind stock, material and heat treatment, so problems are solved before machining starts.
Certified, documented quality
ISO 9001:2015 and IATF 16949 certified quality system. A dimensional report, material certificate and hardness results ship with every order; FAI and PPAP documents on request.
One spare or a production batch

Surface Treatments That Extend Tool Life
The right treatment reduces wear, galling and corrosion. Coating and finishing are specified with the part and controlled by the same project engineer.
Mirror Polishing
Ra 0.05 µm by progressive diamond polishing, for mold cavities where part appearance and clean release matter.
Hard Chrome Plating
Electrolytic hard chrome (HV 800–1000) for wear resistance on punches, pins and sliding components.
TiN / TiCN / TiAlN PVD
Physical vapor deposition coatings (HV 2,300–3,000) that raise surface hardness, cut friction and can extend punch and die life several times over uncoated steel.
Gas & Plasma Nitriding
A diffused nitrogen-rich case that improves fatigue strength and seizure resistance with minimal dimensional change.
Black Oxide
Chemical conversion coating for mild corrosion resistance and low glare on non-wear surfaces.
DLC Diamond-Like Carbon
A hard, very low-friction carbon coating (typically HV 1,500–3,000) for galling-prone forming and sliding parts.
EDM Surface Texturing
Controlled EDM textures on mold inserts for release behavior and matte part finishes.
Electroless Nickel
Uniform EN coating (HV 500–700) that covers complex geometry evenly and resists corrosion.

Custom Tooling Spare Parts Manufacturing: Questions Buyers Ask
What do you need to quote a custom tooling spare part?
A 2D drawing (DWG, DXF or PDF) or 3D model (STEP, IGES), plus material, hardness, coating and quantity. If any of these are missing, our engineers will ask. Our quote checklist lists what speeds up pricing.
Can you make a spare part without a drawing?
Yes. Send the worn or broken part. We measure it on CMM and optical equipment, model it, and send you a drawing to approve before manufacturing the replacement.
Is there a minimum order quantity?
No. We make single replacement punches or inserts as readily as batches of interchangeable spares, and keep your drawing revision on file for repeat orders.
How long does it take to make tooling spare parts?
Typically 7–15 days, depending on complexity, heat treatment and coating. Urgent replacements can be expedited. You receive a quote with DFM notes within 24 hours.
What tolerance can you hold on punches and inserts?
±0.002 mm on ground diameters and profiles. Your drawing tolerances are reviewed during DFM, and critical dimensions are verified on CMM before shipment.
What documents come with the parts?
A dimensional inspection report, material certificate and hardness results with every order. First article inspection (FAI) and PPAP documents are available on request.
Do you make parts to DIN, ISO, HASCO or MISUMI standards?
Yes. Standard-dimension components are listed in our tooling spare parts catalog, and we modify standard parts or make fully custom ones to your print.
How are spare parts packed and shipped?
Parts are coated with rust-preventive oil, VCI-wrapped, boxed or crated, and shipped by courier, air or sea. We prepare export documents and quote EXW, FOB or DDP terms.
