Description

1. Core Product Advantages

  • High Corrosion Resistance and Strength: By using materials like Hardened Metals, alloy steels, and stainless steels, and enhancing corrosion resistance through chemical surface treatments such as anti – rust coatings and anodizing, these parts are suitable for harsh environments with high humidity, strong acids, or alkalis.
  • Precision Machining Capability: Relying on advanced equipment such as 3 – axis, 4 – axis, and 5 – axis CNC machines and Wire Electrical Discharge Machining (Wire EDM), ultra – high precision ranging from ±0.01mm to ±0.005mm can be achieved, meeting the requirements for complex structural components and micro – machining.
  • Multi – material Adaptability: It supports full – process machining including turning, milling, drilling, and laser cutting of materials such as aluminum, brass, titanium alloy, bronze, and stainless steel, covering demands from prototyping to mass production.

2. Service Content

  • Customized Machining: Provide OEM/ODM services. Non – standard parts can be customized according to customer drawings in formats like PDF, DWG, and IGS. Support is available from small – batch trial production to large – batch delivery.
  • Diverse Processes: Encompass chemical etching, laser processing, micro – machining, rapid prototyping, etc., meeting the lightweight and high – strength requirements of fields such as automotive, aerospace, medical equipment, and industrial machinery.
  • Supporting Services: Include surface treatment (polishing, sandblasting, plating), quality inspection (full – size inspection, material composition analysis), and logistics packaging (shock – proof and moisture – proof solutions) to ensure worry – free delivery.

3. Quality and Efficiency Assurance

  • Strict Quality Control: Certified by ISO 9001, equipped with devices like Coordinate Measuring Machines (CMM) to ensure that each batch of products meets the drawings and industry standards.
  • Quick Response: Standard parts can be delivered within 7 – 15 days. Urgent orders can be shortened to 5 days, and global logistics tracking is supported.
