The company’s 3,000㎡ production facility houses advanced equipment including 30+ stamping presses (30-250 ton capacity), 30+ CNC machining centers (including automatic lathes and Swiss-type machines), and specialized injection molding equipment. This comprehensive setup enables seamless production of three core product lines: precision stamping components, CNC machined parts, and injection-molded accessories.
A dedicated team of 16 technical professionals and 7 senior technicians works closely with clients throughout the product development lifecycle. From initial design consultation to final quality inspection, the company maintains strict adherence to ISO 9001:2015 standards, ensuring consistent product quality across all orders. This systematic approach has enabled successful partnerships with Fortune 500 companies in automotive, new energy, medical equipment, and industrial machinery sectors.
Core Product Specializations
The company’s flagship metal shovel product exemplifies its engineering excellence. Manufactured through single-piece stretching and bending from solid metal sheets, these shovels feature integrated reinforcement ribs and smooth curved surfaces that eliminate the need for secondary processing. Customers benefit from reduced assembly costs through standardized mounting holes and material options including cold-rolled steel, stainless steel, aluminum alloy, and copper.
For electrical connectivity applications, the CNC-machined brass connection rods offer precise dimensional control (±0.01mm tolerance) and superior surface finish. Made from high-conductivity brass with optional material substitutions (phosphor bronze, copper, aluminum), these components undergo specialized treatments including tin plating, zinc plating, and polishing to meet specific environmental requirements. Typical applications include automotive connectors, new energy equipment, and medical instrumentation.
Material Processing Expertise
The company’s material processing capabilities cover a wide spectrum of metals and alloys:
- Ferrous Metals: Cold-rolled steel, stainless steel (304/316), spring steel
- Non-Ferrous Metals: Brass (H62/H65), phosphor bronze, beryllium copper, aluminum alloy (6061/7075)
- Specialty Materials: Titanium alloy, nickel-based alloy, engineering plastics (POM, PA66, PEEK)
Surface treatment options include zinc plating, nickel plating, chrome plating, anodizing, passivation, and powder coating, with salt spray testing capabilities up to 1,000 hours for corrosion resistance verification. This comprehensive material expertise enables customized solutions for diverse operating environments.
| Product Category | Key Features | Typical Applications |
|---|---|---|
| Precision Stamping | Single-piece construction, ±0.05mm tolerance, 50-500K piece capacity | Electrical connectors, automotive brackets, medical device housings |
| CNC Machining | ±0.01mm precision, complex 3D geometries, multi-axis processing | Shafts, bushings, valve components, optical fixtures |
| Injection Molding | Engineering plastics, 50-5000g mold capacity, secondary operations | Enclosures, handles, gears, structural components |
Customization Process Excellence
The company’s customer-centric approach begins with detailed technical consultations to understand specific application requirements. For new product development, the engineering team provides DFM (Design for Manufacturing) analysis and prototyping services using advanced simulation software to optimize designs for production efficiency.
Production flexibility supports both small-batch sampling (from 100 pieces) and high-volume manufacturing (up to 500,000 pieces/month). The company’s ERP system enables real-time production tracking and quality documentation, while dedicated project managers ensure timely delivery through optimized production scheduling.
Quality control measures include:
- Incoming material inspection with spectral analysis
- In-process CMM measurement (±0.005mm accuracy)
- 100% functional testing for critical dimensions
- Destructive testing for material verification
- Final inspection reports with dimensional data
Industry Solutions
The company’s expertise extends across multiple industries with specialized solutions:
- Automotive: Precision stamping for sensor housings, CNC-machined valve components, corrosion-resistant connectors
- New Energy: High-conductivity busbars, battery terminal connectors, insulation components
- Medical: Biocompatible material processing, cleanroom-compatible manufacturing, traceability documentation
- Industrial: Wear-resistant bushings, high-strength fasteners, precision positioning components
FAQ
What materials can you process for conductive components?
We offer comprehensive material solutions including brass (H62/H65), phosphor bronze, beryllium copper, aluminum alloy, and stainless steel. For high-corrosion environments, we recommend nickel-plated brass or titanium alloy options. Our material laboratory can provide conductivity testing reports and corrosion resistance data for material selection.
How do you ensure dimensional accuracy in CNC machining?
Our quality system implements three-level inspection: in-process measurement using digital calipers, first-article inspection with CMM, and final random sampling. For critical dimensions (±0.01mm tolerance), we employ automatic in-line gauging systems that reject out-of-spec components immediately during production.
What is your minimum order quantity for custom parts?
We support both prototyping and mass production. For stamping components, the MOQ starts at 100 pieces for simple designs and 500 pieces for complex geometries. CNC machined parts have no strict MOQ, though unit costs decrease significantly at volumes above 1,000 pieces due to optimized tooling usage.
How do you handle design modifications during production?
Our engineering team reviews all modification requests through formal ECN (Engineering Change Notice) procedures. For minor adjustments, we can implement changes within 48 hours without disrupting production. Major design changes may require new prototyping, which we typically complete within 5-7 working days.
