With 70 dedicated employees, we maintain strict quality control throughout the entire production process – from design and prototyping to mass production and after-sales service. Our ISO 9001:2015 certification demonstrates our commitment to maintaining international quality standards in all our operations.
Core Product Offerings
As a custom hardware manufacturer, we specialize in three main product categories, each designed to meet specific industrial requirements:
1. Precision Metal Stamping Parts
Our metal shovel is a prime example of our stamping capabilities. Manufactured from a single piece of material through integrated stretching and bending processes, this product features no joints or welds, ensuring exceptional durability and resistance to bending or cracking. The built-in reinforcement ribs, smooth rounded shovel surface, and standard mounting holes provide excellent material handling performance and easy assembly without secondary processing.
We offer customization options including various materials (cold-rolled steel, stainless steel, aluminum alloy, copper), dimensions, and finishes to suit different equipment and working environments. This product effectively reduces our clients’ production and assembly costs while maintaining high quality standards.
2. CNC Machined Components
Our brass connector rods exemplify our precision CNC machining capabilities. These one-piece components feature precise dimensions and smooth surfaces without burrs, ensuring smooth insertion and removal without jamming. Made from high-quality brass, they offer excellent electrical and thermal conductivity while being resistant to oxidation and corrosion.
We provide material substitution options including phosphor copper, red copper, aluminum, and iron, along with customizable dimensions, structures, and surface treatments like tin plating, zinc plating, and polishing. These components are widely used in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals.
3. Custom Injection Molded Parts
Our precision knurled zinc-plated bushings (metal sleeves) demonstrate our injection molding expertise. Manufactured through CNC integrated turning, these bushings feature smooth inner walls, precise dimensions, and a knurled middle section that significantly increases assembly friction to prevent slippage during equipment operation.
The zinc plating provides excellent corrosion resistance and extends product lifespan. We support multiple material options including iron, stainless steel, brass, and aluminum, along with various surface treatments. These bushings find applications in fasteners, wire harness connectors, instrument sleeves, furniture hardware, and mechanical positioning.
