A hydraulic press machine for bicycle aluminum alloy hydroforming is a specialized piece of equipment used in the manufacturing of lightweight, high-strength bicycle components such as frames, handlebars, and forks. Hydroforming is a metal-forming process that uses high-pressure hydraulic fluid to shape aluminum alloy tubes into complex, structurally efficient designs.

Three Core Technologies to Solve the Problem of Parts Forming
● High-Precision Micro-Molding Technology, Micron-Level Precision Control
Most bicycle parts are thin-walled and complex curved structures, such as aluminum alloy frame tubes, carbon fiber front forks, steel gears, etc., which require extremely high molding precision. The high-precision micro-molding system equipped with Goodsjack servo  hydraulic press machine achieves pressure control accuracy of ±0.1% and displacement accuracy of ±0.02mm through four-cylinder synchronous control technology (synchronous error ±0.01mm) and servo hydraulic drive. In the bending and forming of aluminum alloy frame tubes, this technology can accurately control the bending angle (error <0.5°) and the uniformity of tube wall thickness to avoid wrinkles and thinning defects in traditional processes; for the compression molding of carbon fiber composite materials, the gradient pressure loading technology is used to ensure uniform distribution of material fibers, improve part strength and fatigue resistance, and meet the stringent requirements of competition-level bicycles.
● Lightweight Flexible Molding Solution, Adaptable to Multiple Materials
In response to the lightweight trend of bicycle parts (aluminum alloy, magnesium alloy, carbon fiber and other materials account for more than 80%), Tengzhou Taili CNC adopts flexible structural design and intelligent material adaptation technology.
Material Adaptive System: The sensor can identify the material hardness and ductility in real time and automatically adjust the pressure curve. For example, when processing 6061 aluminum alloy wheels, the system can use a "slow first and then fast" pressure output in the stretching stage to avoid edge cracking; when processing carbon fiber prepreg, the molding temperature (±1°C) and pressure holding time are precisely controlled to ensure that the composite material is fully cured.
Modular mold interface: It supports the rapid replacement of special molds for different materials, and cooperates with automatic centering technology (positioning accuracy ±0.05mm) to achieve seamless switching between the production of aluminum alloy parts and carbon fiber parts, meeting the production needs of enterprises with multiple materials and varieties.
● Intelligent Flexible Production System to Cope with Small Batch Customization
Facing the personalized needs of the bicycle market (the proportion of customized parts has increased to 30% year by year), the hydraulic press is equipped with an intelligent process library and a fast mold change system:
Self-learning of process parameters: More than 100 kinds of bicycle parts molding process solutions are built-in, and custom parameter import is supported. New operators can quickly call through the graphical interface to avoid manual debugging errors.

Full-scenario application, covering the entire field of parts forming
Frame system: creating a lightweight "skeleton"
Aluminum alloy frame: through multi-station forming technology, the tube bending, punching and forming are completed at one time, ensuring the interface accuracy of each tube of the frame (matching clearance <0.2mm), improving the assembly efficiency and riding rigidity of the whole vehicle.
Carbon fiber frame: high-precision compression molding technology ensures that the carbon fiber layers fit tightly, eliminates bubble defects, and increases the frame strength by 15% and reduces the weight by 20% compared with traditional processes, meeting the ultimate lightweight requirements of competition-level frames.
Wheel system: shaping stable "feet"
Aluminum alloy wheel: in the stretch forming of the wheel, through the precise matching of pressure and speed (speed adjustment accuracy ±5mm/s), ensure that the rim edge is smooth and the spoke hole position error is <0.1mm, improve the dynamic balance performance of the wheel and reduce riding vibration.
Magnesium alloy wheel rims: In view of the easy oxidation characteristics of magnesium alloy, the hydraulic press is equipped with an inert gas protection mold cavity, and with a rapid cooling system, the surface oxidation rate of the wheel rim after molding is reduced from the industry average of 10% to below 2%.
Transmission and braking system: Precision control of "joints"
Gears and sprockets: High-precision cold extrusion molding technology makes the gear tooth profile error <0.05mm and the surface roughness Ra≤0.8μm, reducing transmission noise and wear and extending service life.
Brake parts: In the molding of brake discs and brake arms, multi-directional pressing technology is used to ensure the accuracy and rigidity of complex curved surfaces and improve the braking response speed and safety.
