Frame Manufacturing

Aluminum, steel, or titanium tubes are cut into segments based on the design’s length and angle. Using TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding techniques, the tubes are welded into the frame structure. The weld seams are then ground and heat-treated to enhance strength and improve the appearance. The surface is polished, painted, or anodized for corrosion resistance and aesthetic appeal.

Mainly used for aluminum or titanium frames, this process is ideal for producing high-strength, lightweight components like head tubes and bottom brackets. The material is heated and forged in a mold under high pressure. After forging, the parts are machined and heat-treated to optimize frame hardness and toughness.

Mainly used for aluminum frames, especially for lightweight designs. Heated aluminum is extruded through a mold into hollow or solid tubes with varying thickness and cross-sections. The tubes are cut, bent, and welded into a frame, followed by heat treatment and surface finishing like anodizing or painting to enhance strength and appearance.

Primarily used for aluminum alloy frames, this process involves placing aluminum tubes in molds and using high-pressure liquid to expand the tubes into the desired shapes. The formed tubes undergo cutting, welding, and grinding to complete the frame structure. Hydraulic-formed frames are also subjected to heat treatment and surface treatment to increase strength and durability.

It is mainly used for casting aluminum alloys and metal components, where gravity is employed to pour molten metal into molds to form high-precision castings. Gravity casting is suitable for producing parts with com plex structures and high strength requirements, such as frames, wheel hubs, and battery brackets, meeting the demands for lightweight, strength, and durability in component manufacturing.

Post-welding, the frame enters the T4 heat treatment line. This process enhances the strength and ductility of aluminum alloys by heating and rapidly cooling the material, relieving welding stresses. The physical properties of the frame are significantly improved, ensuring stability and durability during use and preparing it for further processing.

After T4 treatment, the frame proceeds to the T6 heat treatment line. Through higher temperature heating and aging treatment, the strength and hardness of the aluminum alloy are further increased. This process ensures that the frame maintains excellent performance under extreme conditions, meeting the demands of high-strength applications and providing robust support for the final product.

Following heat treatment, the frame undergoes powder coating. In a state-of-the-art clean room powder coating line, high-quality powder coatings are applied to ensure an even layer with strong adhesion. This process not only enhances the frame’s appearance but also increases its corrosion resistance, ensuring it remains in good condition in various environments.
