OEM / ODM Customization Capability
From concept development to final assembly, our engineering team supports customized manufacturing solutions tailored to global market standards.
OEM 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.
Key Steps
T4 heat treatment T6 heat treatment Controlled solution and aging processes Deformation management systems
Adjustment & Calibration
After thermal processing, components undergo structural alignment and dimensional verification to ensure assembly accuracy and production consistency.
Surface finishing enhances corrosion resistance and product appearance, while final assembly ensures structural reliability and delivery readiness.
Key Steps

Success Cases
Our work is trusted by industry leaders and spans multiple sectors where strength, safety, and durability are essential.
Trusted by Leading Brands
Our proven manufacturing quality has earned the trust of top companies in cycling and transportation. We have produced aluminum frames for Giant, Taiwan’s largest bicycle brand, and supplied seat-frame structures for THSR(Taiwan High Speed Rail) and Puyuma Express, where safety and structural performance are non-negotiable. These long-term partnerships reflect our commitment to stable production, precision welding, and consistent delivery for demanding applications.
Services Across Multiple Industries
Our OEM capabilities extend far beyond cycling. We support a wide range of industries that rely on lightweight yet strong aluminum structures, including:
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.
