HWPD provides one-stop product development and custom injection molding services across the entire product lifecycle, from product design and engineering support to rapid prototyping, prototype tooling, injection mold manufacturing, plastic injection molding, and OEM/ODM production.
With design, prototyping, tooling, molding, and manufacturing coordinated under one roof, you can reduce lead times and supplier risk while maintaining consistent quality from prototype to production.
20+ years of mold and manufacturing experience | DFM and engineering support | Prototype, low-volume and mass production
Product Design & Development | Rapid Prototyping | Prototype Injection Molds |
Production Injection Molds | Large Injection Molds | Plastic Injection Molding |
ODM Finished Product Manufacturing |
Our in-house product design team combines industrial design with mechanical engineering to develop products that are both market-competitive and optimised for efficient injection mold manufacturing. Before any design work begins, we conduct thorough market and feasibility research to ensure the end product meets real customer demand while remaining cost-effective to produce at scale.
With over 20 years of hands-on experience in the OEM production field, we understand the tooling and production challenges that arise during mass manufacturing — and we address them proactively at the design stage. Our DFM (Design for Manufacturability) review process helps clients avoid costly late-stage design changes.
Complex geometry part reviewed at design stage for injection mold compatibility
We offer a full range of rapid prototyping and prototype manufacturing methods to suit every stage of product development — from early concept validation to pre-production functional testing. Our team selects the most appropriate and economical prototyping process based on your timeline, accuracy requirements, and intended use.
Available prototyping methods include CNC prototyping, 3D printing (FDM, SLA, SLS), vacuum casting, rotational molded prototypes, and injection-molded prototypes. All surface finishing, painting, and pad printing work is completed in our clean-room facility to ensure presentation-grade results.

Beyond standard rapid prototypes, HWPD specialises in high-precision injection-molded prototypes — particularly for components used in automotive systems, communication equipment, and medical instruments where dimensional accuracy and material performance are critical.
Our injection-molded prototypes are produced using the same injection mold tooling process and real production-grade plastic materials as mass-production parts. This means the prototype's dimensional accuracy, surface finish, and mechanical properties are directly representative of the final production component.
Production-equivalent material properties | Same injection mold process as mass production | Tighter dimensional tolerances |
Shorter overall development cycle | Reduced development cost | Faster new product launch |
Our prototype injection molds can serve dual purposes: engineering validation during new product development, and small-batch pre-production runs before committing to full production tooling.
High-precision injection-molded prototype parts across automotive, medical, and communication applications
In addition to prototype molds, HWPD is a leading medium-to-large professional injection mold manufacturer in China, with over 20 years of dedicated expertise in producing high-precision structural molds for the automotive, medical device, communication equipment, and office automation sectors. Our facility is equipped with advanced CNC machining centres, EDM machines, and high-precision measurement systems operated by experienced tooling engineers.
Our injection mold technology portfolio covers a comprehensive range of specialised processes:
▸ Overmolding — bonding two materials or components within a single mold cycle
▸ Two-shot (2K) molding — producing two-material parts in one injection cycle
▸ In-Mold Decoration (IMD) — integrating surface graphics within the mold
▸ In-Mold Labeling (IML) — embedding labels during the injection process
▸ Hot runner systems for large, complex molds requiring precise gate control

As a trusted automotive mold specialist, HWPD has maintained long-term partnerships with globally recognised automakers for over 20 years, including Volvo, BMW, Mercedes-Benz, General Motors, Ford, Volkswagen, and Nissan. Our automotive injection molds cover the full spectrum of vehicle components:
Category | Typical Components |
Exterior Parts | Bumpers, grilles, fenders, wheel arches, rain gutters, door handles, rearview mirror housings, automotive lamps |
Interior Parts | Door panels, A/B/C pillars, instrument panels, glove boxes, centre consoles |
Engine Peripherals | Intake manifolds, air filter housings, fuel rails, cylinder head covers |
HVAC & Other | Heating and cooling system components, fluid circuit parts, structural brackets |
Move from validated tooling to custom injection-molded plastic parts for prototype, low-volume and small-batch injection molding, as well as mass-production programs. DFM, tooling, molding, and production coordination are managed by the same project team.
HWPD processes engineering plastics including ABS, PC, PP, PA, POM, TPE, PPS, and PEI according to project requirements.
