- No splicing or welding for superior durability
- Integrated reinforcement ribs for added strength
- Smooth, rounded shovel surfaces for efficient material handling
- Standard mounting holes for easy assembly
- Customizable in cold-rolled steel, stainless steel, aluminum, copper, and other materials
2. CNC Machined Components
Our brass connecting rods exemplify our CNC machining expertise with features including:
- One-piece molded construction for precise dimensions
- Smooth surface finish with no burrs
- Excellent electrical and thermal conductivity
- Corrosion-resistant brass material with alternative options available
- Customizable in various sizes, structures, and surface treatments
These components serve critical functions in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals through their reliable conductive properties.
3. Custom Injection Molded Parts
Our precision knurled zinc-plated sleeves demonstrate our injection molding capabilities with:
- Numerically controlled one-piece turning for smooth walls
- Middle knurling design preventing equipment slippage
- Zinc plating for enhanced corrosion resistance
- Customizable in multiple materials and surface treatments
- Variable dimensions including diameter, length, and wall thickness
These versatile components find applications in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning systems.
Industry Applications and Client Success Stories
Our components serve diverse industries including new energy, automotive, electrical appliances, medical equipment, instrumentation, and machinery manufacturing. One notable project involved developing custom brass electrodes for a leading European automotive manufacturer that required precise dimensional control and excellent conductivity.
By collaborating closely with the client’s engineering team, we optimized the component design to reduce material waste by 15% while improving electrical performance by 20%. The successful implementation led to a long-term supply agreement and subsequent orders for additional component lines.
Quality Assurance and Certification
Our ISO 9001:2015 certified quality management system ensures every component meets stringent specifications through:
- Incoming material inspection
- In-process quality control
- Final product testing
- Batch traceability
- Continuous improvement processes
We maintain complete documentation for all production runs and can provide material certificates, inspection reports, and other quality documentation upon request to support our clients’ quality assurance requirements.
| Quality Control Stage | Inspection Method | Acceptance Criteria |
|---|---|---|
| Incoming Materials | Spectral analysis, hardness testing | Meets material specification standards |
| In-Process | Dimensional inspection, visual inspection | Within specified tolerances |
| Final Product | Functional testing, salt spray test | Meets performance requirements |
FAQ
What materials can you use for custom brass electrodes?
We offer standard brass electrodes in C2680, C3604, and C3771 brass alloys, with alternative options including phosphor copper, red copper, aluminum, and iron based on specific application requirements. Our material selection considers conductivity, corrosion resistance, strength, and cost factors.
How do you ensure dimensional accuracy in CNC machined components?
Our CNC machining centers maintain positional accuracy within ±0.005mm and repeatability within ±0.003mm. We implement comprehensive quality control including in-process inspection with CMM measurement and final product testing to ensure all dimensions meet specifications.
What is your minimum order quantity for custom metal components?
We accommodate both small batch production and large volume orders. Our MOQ starts at 100 pieces for simple components, with flexible arrangements for complex parts or new product development projects. We also offer prototype services with quantities as low as 1-10 pieces.
How long does it take to produce custom metal components?
Production lead times vary based on component complexity and order quantity. Simple stamped parts typically require 15-20 days, while CNC machined components need 20-25 days. For injection molded parts requiring new mold development, allow 30-45 days including mold making and sampling.
Can you provide surface treatment services for metal components?
Yes, we offer comprehensive surface treatment options including zinc plating, nickel plating, chrome plating, tin plating, anodizing, passivation, sandblasting, and powder coating. Our plating thickness ranges from 3-20μm depending on the application requirements.
