JUPAICNC provides the automotive industry with full-dimensional precision machining technology empowerment, covering everything from core components to intelligent production systems. With five-axis linkage machining centers and high-precision turning and milling equipment, we can perfectly process key components such as engine blocks and gearbox gears, with a tolerance accuracy of up to ±0.005mm. Through the intelligent MES production management system, digital control of the entire process from raw materials to finished products is achieved to ensure quality traceability and production stability. In response to the lightweight needs of new energy vehicles, we have unique process advantages in the processing of aluminum alloys and carbon fiber composite materials, which can help customers achieve a weight reduction of more than 30%. At the same time, the flexible production line design supports rapid changeover to meet the customized needs of multiple varieties and small batches.
Tensile strength 500-1500MPa, used for body structural parts, improving collision safety while achieving lightweight.
Low density (2.7g/cm³), corrosion resistance, used in engine blocks and body panels, with significant weight reduction effects.
High strength, good toughness, used for crankshafts and differential housings, balancing cost and performance.
30% glass fiber reinforced, high temperature resistant, low friction, used for intake manifolds and bearing covers, replacing metal to reduce weight.
Its specific strength is 5 times that of steel and is used in battery boxes and structural parts of new energy vehicles, making it extremely lightweight.
High strength, corrosion resistance, used in high-performance car connecting rods and exhaust systems, but the cost is relatively high.
A dense oxide layer is formed on the surface of aluminum alloy through electrolysis, which improves corrosion resistance (salt spray test for more than 500h) and enhances surface hardness (HV800+). It is suitable for new energy battery housings, motor end covers and other parts.
Using low-temperature technology to generate a 50-100μm thick oxide film with a surface hardness of HV1200, it is used in scenarios that require wear resistance, such as transmission valve bodies and hydraulic components.
The electroplating layer has a thickness of more than 12μm, and the neutral salt spray test is more than 720h without rusting, meeting the long-term anti-corrosion requirements of automotive bolts, clamps and other parts.
Vacuum ion plating of titanium/chrome achieves mirror-grade gloss (Ra≤0.1μm) and scratch resistance. It is used for exterior parts such as door handles and signs, taking into account both beauty and durability.
Epoxy resin powder is sprayed and cured to form a 80-120μm coating that is stone-impact and chemical-resistant, suitable for outdoor exposed parts such as chassis parts and suspension components.
