Core Product Lines and Customization Options
We specialize in three main product categories: precision stamping parts, CNC machined components, and injection molded parts. Each product line offers extensive customization options to meet diverse industry needs:
Precision Stamping Parts
Our metal shovels exemplify our stamping expertise. Manufactured from single sheets of material through integrated stretching and bending processes, these products feature no joints or welds, ensuring exceptional durability and resistance to bending or cracking. The built-in reinforcing ribs, smooth arc surfaces, and standard mounting holes facilitate easy assembly and smooth material handling. We offer customization in materials including cold-rolled iron, stainless steel, aluminum alloy, and copper, making these shovels suitable for various industrial equipment applications.
CNC Machined Components
Our brass connecting rods demonstrate our precision CNC machining capabilities. These one-piece components feature precise dimensions and smooth surfaces without burrs, ensuring smooth insertion and removal. Made from high-quality brass, they offer excellent electrical and thermal conductivity while being resistant to oxidation and corrosion. We can produce these components in various materials including phosphor copper, red copper, aluminum, and iron, with customizable dimensions, structures, and surface treatments like tin plating, zinc plating, and polishing. These versatile components find applications in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
Injection Molded Parts
While our core expertise lies in metal fabrication, our injection molding capabilities allow us to offer comprehensive solutions. We can produce plastic components that perfectly complement our metal parts, creating integrated assemblies that reduce our clients’ supply chain complexity. Our injection molding machines enable us to produce parts with consistent quality and tight tolerances, meeting the stringent requirements of various industries.
Specialized Custom Metal Solutions
Beyond our standard product lines, we excel at creating non-standard custom metal parts tailored to specific client needs. Two of our specialized offerings demonstrate this capability:
Precision Knurled Zinc-Plated Sleeves
These non-standard metal bushings are CNC turned in one piece, featuring smooth tube walls and precise dimensions. The middle knurling design significantly increases assembly friction, preventing slippage or loosening during equipment operation. After zinc plating for rust prevention, these components offer excellent corrosion resistance and long service life. We can produce these sleeves in various materials including iron, stainless steel, brass, and aluminum, with customizable tube diameters, lengths, and wall thicknesses. They find wide applications in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning.
Brass Stretched Shells for Connectors
Our precision stamped and stretched brass shells are seamless and compact, with precise positioning for smooth insertion and removal. Made from high-quality copper materials, they offer stable electrical conductivity and excellent corrosion resistance. We can produce these shells in various materials with customizable dimensions, structures, and premium surface treatments like gold, silver, or nickel plating. These specialized components primarily serve as enclosures for aviation plugs, new energy connectors, wire harness terminals, and sensors.
