HWPD provides clients with a complete ODM and OEM product manufacturing service — spanning every stage from initial product concept and industrial design through prototyping, injection mold fabrication, plastic injection molding, assembly, and finished product delivery. With over 30 years of experience in the OEM production field, we serve as a single-source manufacturing partner for clients seeking a reliable, cost-effective, and technically capable route from design to market.
Our ODM manufacturing capability is built on the same engineering and production infrastructure that supports our mold making and injection molding services — giving clients direct access to in-house design expertise, tooling capability, and production capacity without the complexity and risk of managing multiple suppliers.

One-Stop ODM Manufacturing Solution
HWPD's one-stop ODM service consolidates the entire product development and manufacturing lifecycle under unified technical management. Rather than coordinating separate design studios, prototype houses, toolmakers, and molders, clients work with a single engineering and production team — from concept briefing through to mass production sign-off.
HWPD one-stop ODM service: from product design and prototyping through mold fabrication, injection molding, and finished product delivery
One engineering team. One quality standard. One point of contact. By managing design, tooling, and production in-house, HWPD eliminates inter-supplier miscommunication, compresses development lead times, and maintains consistent quality from prototype to mass production. |
ODM Service Stages
Our ODM manufacturing service follows a structured development workflow, with clear deliverables and client review points at each stage:
Stage 01 Product Design & Development Industrial design, market research, DFM analysis, 3D CAD modelling, and engineering feasibility review. We develop designs optimised for both market performance and cost-effective production. | Stage 02 Prototyping & Validation 3D printing, CNC machining, vacuum casting, and injection-molded prototypes for functional and appearance validation. Multiple prototype iterations supported at each development phase. | Stage 03 Mold Fabrication Prototype injection molds for pre-production validation and production molds for mass manufacturing — built to the same precision standard with full DFM review and mold trial reporting. |
Stage 04 Plastic Injection Molding High-volume injection molding on our 60-machine production floor (120T–1,500T), with in-process QC, dimensional inspection, and PPAP documentation for production release. | Stage 05 Assembly & Finishing Surface treatment, painting, printing, ultrasonic welding, heat staking, and sub-assembly — producing complete finished components or assembled products ready for packaging. | Stage 06 Packaging & Delivery Custom packaging design, export packaging, and global freight coordination — delivering finished products direct to your warehouse, distribution centre, or end customer. |
Product Design & Industrial Engineering
Our in-house product design team brings together industrial designers and mechanical engineers with over 20 years of combined OEM production experience. This background in real-world manufacturing ensures that every design decision is evaluated against its downstream impact on tooling cost, production efficiency, and product quality — not just aesthetic intent.
We conduct thorough market and feasibility research before initiating design work, with the goal of developing products that meet genuine market demand while remaining cost-competitive to manufacture at volume.
▸ Industrial design and product concept development ▸ Market research and product feasibility analysis ▸ 3D CAD modelling and structural simulation ▸ DFM review and mold flow analysis ▸ Material selection and cost optimisation ▸ Design iteration support through prototyping stages ▸ Engineering change management and design revision control |
Product design and DFM review — integrating manufacturability into the design process from the outset |
Rapid Prototyping for ODM Development
Effective ODM product development requires the right prototyping method at each stage. HWPD's engineering team selects the most appropriate prototyping process for each development phase, based on the specific validation objectives and timeline.
3D Printing (FDM / SLA / SLS) Fast, low-cost concept models for early-stage design review, ergonomic evaluation, and stakeholder presentations. | CNC Machined Prototypes High-accuracy prototypes from engineering plastics or aluminium for functional and structural testing where 3D print materials are insufficient. | Vacuum Casting Silicone mould casting for small batches of appearance-quality prototypes in production-representative polyurethane materials. |
Injection-Molded Prototypes Low-cost prototype injection molds producing real production-grade plastic parts — dimensional accuracy and material properties equivalent to mass production. | Surface Finishing Clean-room painting, pad printing, texture application, and chrome plating for presentation-quality prototype finishes matching final product specifications. | Assembly Validation Multi-component prototype assembly and fit checks — validating assembly sequences, interference, and tolerance stack-up before production tooling is committed. |
OEM Production & Quality Management
Our OEM production team combines deep manufacturing experience with disciplined quality management systems. With over 30 years of experience producing high-quality plastic components and finished products for export, we operate robust Design Verification & Validation (DVV) procedures and a comprehensive QC management system covering every stage from incoming material inspection through final shipment release.
Structured OEM production workflow with integrated quality control at every stage | ▸ Design Verification & Validation (DVV) procedure throughout development ▸ First Article Inspection (FAI) with full dimensional report before production release ▸ In-process QC checks and statistical process control (SPC) ▸ Incoming material inspection and supplier qualification ▸ PPAP documentation for automotive and tier-1 supply chains ▸ Final product inspection and packaging audit before shipment ▸ ISO-aligned quality management system with full traceability |
ODM Manufacturing Process
From initial client brief to finished product delivery, our ODM workflow follows a structured, stage-gated process with clear milestones and client approval points:
STEP 1 Client Brief & Requirements Review | STEP 2 Industrial Design & Concept Development | STEP 3 Prototype Fabrication & Design Validation |
STEP 4 DFM Review & Mold Design | STEP 5 Mold Fabrication & T1 Trial | STEP 6 FAI & Production Approval |
STEP 7 Mass Production | STEP 8 Assembly & Surface Finishing | STEP 9 QC Inspection & Shipment |
