HWPD designs and manufactures custom plastic injection molds for automotive, medical-device housings, industrial equipment, communication products, AI/robotics components and other engineered plastic parts. Our mold program is connected to HWPD’s wider product-development system—DFM, prototyping, prototype tooling, production molds, injection molding and OEM/ODM manufacturing can be coordinated by the same project network.
3D CAD and available 2D drawings
Production resin and any filler / additive requirements
Expected quantity or annual volume
Critical dimensions, assembly interfaces and cosmetic areas
Target mold type, cavity requirement or injection machine information if already defined
Target timing, quality documentation and mold destination
You do not need a fully finished tooling specification to start. Send the current files and project stage; HWPD can first review whether the next step should be design optimization, prototype tooling or a production mold.
Start With Product Development →HWPD does not treat every project as the same production-mold program. The tooling route should match how mature the product is and what still needs to be validated.
For projects that need real molded parts to check resin behavior, shrinkage, assembly, appearance or design changes before committing to long-term production tooling.
Injection-Molded Prototypes →For pre-production, low-volume launch or programs that need molded parts while the final commercial demand is still being confirmed.
Compare Mold Routes →For stable designs that require repeatable production, defined cavity strategy, maintenance planning and long-term molding support.
Production Molds →For larger interior, exterior, structural and functional plastic parts where mold size, rigidity, cooling, handling and trial capacity must be planned together.
Large Injection Molds →The mold structure is selected around the part, resin, assembly requirement, surface standard and production plan—not from a fixed online catalog.
Parting direction, draft, undercuts, gate strategy, cooling, ejection, shrinkage and mold structure are reviewed before steel cutting.
Runner strategy is selected according to resin, part geometry, gate requirement, material use and production economics.
Tooling for plastic parts that incorporate metal or other inserts when the product design requires integrated components.
Multi-material tooling for rigid/soft combinations or molded-over components where bonding and positioning must be controlled.
Two-material or two-color tooling for projects that require controlled indexing, interface design and compatible molding systems.
Injection mold solutions that integrate decorative film or labels into the molding process where required by the product.
This page covers the mold-manufacturing side of the same industries supported across HWPD’s product-development, molding and OEM/ODM services.
Door panels, pillars, instrument panels, glove boxes, bumpers, grilles, wheel arches, mirrors, lamp components, HVAC and engine-peripheral housings.
Automotive Manufacturing →Precision plastic housings and molded components where dimensional control, material selection, assembly and inspection requirements must be defined before tooling.
Robot, communication, office-automation and smart-equipment plastic parts that connect mechanical design, tooling, molding and assembly.
ODM Manufacturing →Industrial housings, appliance-related parts, smart-device housings and other custom products requiring mold manufacturing and repeat molded production.
One-Stop Manufacturing →A commercial mold page should show buyers how the project moves—not bury the process inside a long technical article.
HWPD’s Facilities page carries the full equipment list. The summary below shows the core mold-fabrication and dimensional-inspection resources relevant to this service.
12 CNC machines, including 2 high-speed MIKROIV VCP-600 machines
11 EDM machines, including mirror-surface EDM
5 wire-cutting machines
17 milling machines
8 grinding / precision grinding machines
Hardness, 2D and 3D coordinate measuring equipment
| Equipment | Example Model / Size | Role in Mold Manufacturing |
|---|---|---|
| High-Speed CNC | MIKROIV VCP-600 | High-speed mold machining and precision finishing work |
| CNC | Up to X1450 × Y400 × Z330 listed | Core, cavity and mold-component machining |
| Mirror-Surface EDM | DH-500CNC | Fine EDM work where surface quality or difficult geometry requires it |
| EDM | JFZ-650 | Complex cavity and insert features |
| Wire Cutting | DK-7750 | Precision profiles, inserts and mold components |
| 3D Coordinate Measurement | EXPLORER7107 | Dimensional verification of mold components and tooling features |
Material selection is handled as part of the mold program. Final grades should be matched to part performance, wear, appearance, maintenance and the required production route.
718 / 718-type mold steels
NAK80 for suitable cosmetic / finishing requirements
S136 / stainless-type mold steels for suitable corrosion or polishing requirements
Localized wear inserts or higher-performance materials where the mold design requires them
PP, PE, ABS, PC and PC/ABS
PA / Nylon and glass-filled PA
POM, PBT and other engineering plastics
TPE, TPU, TPV and other elastomer systems where project-compatible
PMMA, ASA, PS and other product-specific materials
The strongest difference between this page and a standalone mold-shop page is that tooling can sit inside a complete product-development and manufacturing route.
Part design, structure, material and manufacturability can be reviewed before mold release.
Product Development →Use real molded parts when shrinkage, warpage, assembly or production-resin behavior must be validated.
Injection-Molded Prototypes →Approved molds can continue into short-, medium- or long-run molded-part production.
Plastic Injection Molding →Projects can continue beyond molded components into secondary processing, assembly and finished-product manufacturing.
ODM Manufacturing →Send the 3D CAD file, available 2D drawing, production resin, expected volume, critical dimensions, surface requirements, assembly information and target timing. Injection-machine information is also useful if the mold must run at the customer’s facility.
Yes. HWPD separates prototype tooling, bridge / low-volume tooling and production molds by project stage, so the tooling investment can match the remaining validation risk and expected production program.
HWPD supports medium and large mold programs for automotive interior, exterior and functional plastic components. Large-tool feasibility is reviewed against the actual part, mold structure, machining, handling and molding requirements.
Available tooling approaches include hot- and cold-runner molds, insert molding, overmolding, two-shot / 2K tooling, IMD and IML, subject to the product and production requirements.
Yes. The mold program connects directly to HWPD plastic injection molding and OEM/ODM manufacturing services when the customer needs molded-part or finished-product production after tooling validation.
Send your part files, resin, expected volume, critical dimensions, cosmetic requirements and project stage. HWPD can review whether you need prototype tooling, bridge tooling, a production mold or a large automotive mold—and connect the approved tool to injection molding or OEM/ODM production when required.
