Core Product Range and Customization Capabilities
As a specialized stamping spring parts manufacturer, we offer three primary product categories with extensive customization options:
1. Precision Stamping Components
Our stamping capabilities cover complex parts with tolerances as tight as ±0.01mm. The metal shovel series exemplifies our manufacturing excellence – produced through single-piece stretching and bending from solid metal plates, these products feature reinforced structures, smooth curved surfaces, and standard mounting holes. Available in cold-rolled steel, stainless steel, aluminum alloy, and copper materials, they serve various industrial equipment applications.
The standard elastic clip represents our mature mass production capabilities. Manufactured through one-piece stamping and bending with quenching treatment, these clips offer stable clamping force and excellent durability. We maintain comprehensive inventory while supporting custom dimensions, materials, and surface treatments to meet specific assembly requirements.
2. CNC Machined Components
Our CNC processing capabilities shine through products like the brass connecting rod. Manufactured as a single piece with precise dimensions and smooth surfaces, these components demonstrate excellent conductivity and corrosion resistance. We offer material alternatives including phosphor copper, red copper, aluminum, and iron, along with customizable surface treatments like tin plating, zinc plating, and polishing.
The precision knurled zinc-plated sleeve (metal bushing) showcases our non-standard customization expertise. CNC turned from solid stock, these bushings feature smooth inner walls and knurled exteriors for enhanced friction during assembly. The zinc plating provides superior corrosion protection, while our ability to process multiple materials and apply various surface treatments makes these components ideal for diverse industrial applications.
3. Injection Molded Parts
Complementing our metalworking capabilities, our injection molding division produces high-quality plastic components that integrate seamlessly with metal parts. This vertical integration allows us to offer complete assembly solutions, reducing clients’ supply chain complexity and improving product consistency.
