Core Product Lines and Customization Capabilities
As a specialized brass electrode manufacturer, we offer comprehensive solutions across three main product categories:
1. Precision Metal Stamping Components
Our flagship product line includes custom-designed metal shovels manufactured through one-piece stretching and bending processes. These components feature:
- Reinforced structure with integral ribs for enhanced durability
- Smooth, rounded shovel surfaces for efficient material handling
- Standardized mounting holes for easy installation
- Material options including cold-rolled steel, stainless steel, aluminum alloy, and copper
The one-piece construction eliminates welding points, significantly improving structural integrity and resistance to bending or cracking. This design reduces customers’ secondary processing requirements, lowering overall production costs.
2. CNC Machined Brass Components
Our brass connection rods represent the pinnacle of precision machining:
- One-piece molded construction with ±0.01mm dimensional accuracy
- Smooth surface finish (Ra≤0.8μm) ensuring smooth insertion and removal
- Material options including high-conductivity brass, phosphor bronze, and aluminum
- Customizable surface treatments like tin plating, zinc plating, and polishing
These components excel in electrical connection applications, offering excellent conductivity while resisting oxidation and corrosion. The precise dimensions ensure compatibility with various connector systems in automotive, new energy, and medical equipment applications.
3. Non-Standard Custom Components
We specialize in producing specialized components like our precision knurled zinc-plated sleeves:
- Numerically controlled one-piece turning for perfect dimensional control
- Middle knurling pattern increases assembly friction by 30%
- Zinc plating provides corrosion resistance for 10+ years
- Customizable parameters including diameter, length, and wall thickness
These sleeves find widespread use in fasteners, wire harness connectors, instrument bushings, and mechanical positioning systems where secure, vibration-resistant connections are essential.
Industry Applications and Solutions
Our components serve diverse industries with tailored solutions:
| Industry | Application Examples | Component Benefits |
