Core Product Lines
Our product portfolio focuses on three main categories of connection components, each designed to address specific industrial requirements:
1. Precision Metal Stamping Connection Parts
Our metal shovel products exemplify our stamping expertise. Manufactured through single-piece stretching and bending from whole metal sheets, these components feature:
- No splicing or welding for enhanced durability
- Integrated reinforcing ribs for added strength
- Smooth, rounded shovel surfaces for efficient material handling
- Standard mounting holes for easy assembly
- Customizable in various materials including cold-rolled steel, stainless steel, aluminum alloy, and copper
These characteristics make our metal shovels ideal for equipment配套 (equipment matching) in diverse industrial settings, reducing clients’ secondary processing costs while ensuring reliable performance.
2. CNC Machined Connection Components
Our brass connecting rods demonstrate our precision CNC machining capabilities. These components offer:
- One-piece molded construction for dimensional accuracy
- Smooth surfaces without burrs for seamless insertion and removal
- Excellent electrical and thermal conductivity from high-quality brass
- Corrosion resistance with optional material substitutions (phosphor copper, red copper, aluminum, iron)
- Customizable dimensions, structures, and surface treatments (tin plating, zinc plating, polishing)
These features make our connecting rods essential for electrical connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals where reliable electrical connections are critical.
3. Non-Standard Custom Connection Parts
Our precision knurled galvanized sleeves (metal bushings) showcase our ability to create tailored solutions:
- Numerically controlled one-piece turning for precise dimensions
- Middle knurling design to prevent slippage during operation
- Galvanized anti-rust treatment for extended service life
- Material flexibility (iron, stainless steel, brass, aluminum)
- Customizable tube diameter, length, and wall thickness
These bushings find widespread application in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning systems where secure, vibration-resistant connections are required.
