Huang Wei is a Taiwanese OEM manufacturer of aluminum and Chromoly steel bicycle frames, backed by 30+ years of precision welding and ISO 9001 quality management. As a Giant OEM supplier, the company operates four welding processes — Smooth, TIG, Brazing, and Laser welding — within a one-stop production flow that runs from design and development support through material preparation, welding, T4/T6 heat treatment, grinding, and finishing. This vertical integration, completed with a third plant in 2025, gives OEM buyers tight dimensional control and a single point of accountability from drawing to finished frame. Samples are available.
HW Technology Co., Ltd. provides complete OEM manufacturing solutions for aluminum structural products. From development and design to welding, heat treatment, surface finishing, and final assembly, all core processes are integrated in-house to ensure quality consistency, production efficiency, and engineering precision.
By combining advanced welding technologies, T4 and T6 heat treatment systems, precision machining, and surface treatment capabilities, we deliver structurally reliable and visually refined products for global OEM / ODM customers.

OEM/ODM Custom Aluminum Manufacturing Capability
From concept development to final assembly, our engineering team supports customized manufacturing solutions tailored to global market standards.
Our OEM Manufacturing Process
A clear and structured OEM process ensures your aluminum frame project moves smoothly from concept to production. Our workflow is designed to reduce uncertainty, accelerate development, and guarantee consistent quality at every stage.
We begin with product design optimization and structural validation to ensure manufacturability and long-term performance. Our engineering team evaluates material selection, welding feasibility, and heat treatment compatibility from the early development stage.
Key Steps
Product design review Structural analysis Prototype development & validation
Material Preparation & Forming
Aluminum materials are processed according to structural requirements, ensuring dimensional accuracy and forming stability before welding. Proper forming control reduces stress concentration and improves final assembly precision.
All welding processes are completed in-house to ensure consistent heat input control and structural integrity. Different welding methods are selected based on product geometry, load conditions, and appearance requirements.
Heat treatment is fully integrated with welding operations to restore and enhance mechanical properties. Controlled thermal cycles ensure strength recovery, fatigue resistance, and dimensional stability across the entire structure.
Surface finishing enhances corrosion resistance and product appearance, while final assembly ensures structural reliability and delivery readiness.

FAQ
What is the minimum order quantity (MOQ) for OEM bicycle frames?
MOQ depends on the frame type, material, tooling requirements, and finishing process, so Huang Wei quotes it per project rather than applying a single fixed number. Aluminum and Chromoly steel programs, painted and raw-finish orders, and repeat versus first-run projects all carry different thresholds. Trading companies and exporters handling smaller multi-batch programs are welcome to discuss requirements directly — contact our sales team with your drawing and target volume for an accurate answer.
Is welding, heat treatment, and finishing all done in-house?
Yes. Huang Wei runs a one-stop production flow covering design and development support, material preparation, welding (Smooth, TIG, Brazing, and Laser), T4/T6 heat treatment introduced in 2018, grinding, and painting or raw finish. A third plant completed in 2025 extended this vertical integration further. For buyers and trading companies, this means one point of accountability from drawing to finished frame, instead of coordinating separate welding, heat-treatment, and painting vendors.
Can I request a sample before placing a production order?
Yes. Huang Wei provides samples for OEM projects. The usual sequence is design and development support, material preparation, welding, T4/T6 heat treatment, grinding, and finishing — the same in-house flow used for production, so the sample reflects what the production frame will be. Sample lead time varies with specification and tooling status. Send your drawing or specification sheet to our sales team to start a sampling enquiry.
Can you help review our drawings before production begins?
Yes. We provide basic feasibility checks to ensure your drawings match our welding and manufacturing capabilities. If any clarification is needed—such as tolerances, material specifications, or assembly order—our engineering team will communicate with you before production starts. All final design decisions remain with the customer.
What information do you need to provide an accurate quotation?
We typically require technical drawings (2D/3D), material specifications, expected quantities, surface finishing requirements, and any performance or testing standards your project must meet.
Do you accept low-volume or prototype orders before mass production?
Yes. We can produce prototypes and small batches for testing and validation prior to scaling into full production.
What is the typical lead time for an OEM aluminum frame project?
Lead times vary by complexity, but prototypes generally take 2–4 weeks, while mass-production schedules are determined after sample approval and material planning.
What welding tolerances and precision levels can you achieve?
We work with tight tolerances suitable for high-end bicycle frames, medical structures, and transportation components. Specific tolerances can be provided based on your drawings and functional requirements.
Can you manage both welding and surface finishing in-house?
Yes. We offer vertically integrated manufacturing, including welding, machining, assembly, and surface finishing—ensuring consistent quality and shorter lead times.
How do you ensure consistency between prototype and mass production?
We standardize welding fixtures, define clear process parameters, and implement ISO-certified quality controls so that every batch matches approved samples.
What industries do you serve beyond cycling?
We supply aluminum frames and welded structures for medical equipment, mobility devices, transportation components, and various industrial applications.
Can we visit your factory for project discussions or audits?
Absolutely. We welcome factory visits for technical reviews, audits, and project meetings to help accelerate communication and build long-term cooperation.
