FRAME MANUFACTURING
The frame is the backbone of your product — the essential foundation for all functionality and safety. Its quality directly determines riding stability, handling, and user safety.PXID operates a fully integrated manufacturing system, from raw materials to finished frames. By controlling core processes — including CNC machining, automated welding, heat treatment, and coating — in-house, we maintain strict oversight of every operation and parameter. Every frame we deliver is more than a component: it’s a guarantee of exceptional strength, millimeter precision, and long-term durability — building unshakable competitiveness into your branded products.
Material cutting & Preprocessing
We use high-precision laser cutting and CNC tube processing to cut and prepare high-strength steel or aluminum tubes. This ensures each tube meets exact design specifications, laying a precise foundation for the welding process.
Welding frame forming process
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.
Profile forging process
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.
Extrusion forming process
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.
Hydraulic forming process
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.
Gravity casting process
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.
3D Full-Dimensional Scanning: Ensuring Millimeter Accuracy
We perform automated full-dimensional scans on every batch of frames using high-precision CMM. By comparing measurement data with the original 3D design model, we guarantee that critical interfaces — such as the head tube, bottom bracket, and rear dropouts — meet 100% of design specifications, eliminating assembly issues or performance loss caused by dimensional variance.
Dynamic Fatigue Testing: Simulating Extreme Conditions, Verifying Longevity
Our lab uses hydraulic servo-powered systems to simulate tens of thousands of impact and cyclic loads — far exceeding real-world conditions. This testing accurately validates the frame’s fatigue strength after extended use, ensuring a design life capable of handling complex riding environments and delivering lasting safety.
Full Bike Road Testing: The Final Validation
Experienced riders put complete bikes through comprehensive road tests at our professional proving grounds. Through gravel roads, jump platforms, and endurance rides, we evaluate the frame's real-world rigidity, noise performance, and long-term reliability — the ultimate and most complete validation before mass production.
