Comprehensive Manufacturing Capabilities

Our company operates a modern 8,000 square meter production facility equipped with state-of-the-art machinery. With over 30 stamping presses ranging from 30 to 250 tons, and more than 30 CNC machining centers including automatic lathes and CNC sliding head machines, we maintain complete control over the entire manufacturing process from design to production. This vertical integration allows us to offer competitive pricing while maintaining the highest quality standards.

Our technical team comprises 16 professional engineers and 7 senior technicians who work closely with customers to develop customized solutions. We specialize in producing three main product categories: precision stamping parts, CNC machined components, and injection molded parts. This diverse capability enables us to serve multiple industries simultaneously while maintaining consistent quality across all product lines.

Core Connector Housing Products

As a specialized connector housing manufacturer, we offer several key products designed to meet the most demanding requirements of modern applications:

1. Brass Connector Rods

Our CNC machined brass connector rods feature precise dimensions and smooth surfaces without burrs, ensuring reliable insertion and removal. Made from high-quality brass, these components offer excellent electrical conductivity and thermal performance while being resistant to oxidation and corrosion. We can customize these rods with various materials including phosphor copper, red copper, aluminum, and iron, along with surface treatments like tin plating, zinc plating, and polishing.

These components are widely used in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals where reliable electrical connections are essential. The dimensional accuracy of ±0.01mm ensures compatibility with the most precise applications.

2. Precision Knurled Galvanized Sleeves

Our non-standard custom metal bushings are manufactured through CNC turning with smooth inner walls and precise dimensions. The middle knurling design significantly increases assembly friction to prevent slippage during equipment operation. After galvanizing treatment, these components offer excellent corrosion resistance and long service life.

We can process these bushings from various materials including iron, stainless steel, brass, and aluminum, with customizable tube diameters, lengths, and wall thicknesses. These versatile components find applications in fasteners, wire harness connectors, instrument bushings, furniture hardware, and mechanical positioning systems.

3. Brass Stretched Copper Shells

As precision stamping and stretching products, our brass copper shells feature seamless construction with compact structure and precise positioning. The smooth insertion and removal characteristics make them ideal for various conductive connection applications. Made from high-quality copper materials, these shells offer stable conductivity and excellent corrosion resistance.

We support customization with multiple material options, dimensional structures, and premium surface treatments like gold plating, silver plating, and nickel plating. These components are primarily used in aviation plugs, new energy connectors, wire harness terminals, sensors, and other precision equipment.

Quality Assurance and Certification

Quality has always been our top priority. We have implemented and maintain an ISO9001:2015 quality management system across all operations. Our comprehensive quality control process includes:

  • Incoming material inspection
  • In-process quality control
  • Final product inspection
  • Dimensional verification using advanced measuring equipment
  • Functional testing for electrical components
  • Surface finish inspection

Our commitment to quality has earned us long-term partnerships with major domestic and international companies across multiple industries. We continuously invest in quality improvement initiatives and employee training to ensure we remain at the forefront of connector housing manufacturing technology.

FAQ

What materials do you use for connector housing production?

We work with a comprehensive range of materials including various copper alloys (brass, phosphor bronze, beryllium copper), stainless steel (304, 316), aluminum alloys (6061, 7075), and engineering plastics (PBT, PA66, PPS) depending on the specific application requirements for conductivity, strength, and corrosion resistance.

How do you ensure dimensional accuracy in connector housing manufacturing?

Our production process incorporates several quality control measures: we use high-precision CNC equipment with ±0.005mm tolerance capability, perform first article inspection for each production batch, and conduct 100% dimensional inspection on critical dimensions using advanced measuring equipment like CMM (Coordinate Measuring Machine).

What surface treatments are available for connector housings?

We offer various surface finishing options to enhance component performance: electroplating (gold, silver, nickel, tin, zinc for corrosion protection and improved conductivity), anodizing (for aluminum components), passivation (for stainless steel), and powder coating (for aesthetic and protective purposes). The selection depends on the specific application environment and requirements.

Can you produce small batch orders for connector housings?

Yes, we support both small batch production and large volume manufacturing. Our flexible production system allows us to efficiently handle orders ranging from prototype samples to mass production quantities. For new projects, we typically recommend starting with a small batch for testing and validation before scaling up to full production.

What is your lead time for custom connector housing orders?

Lead times depend on order quantity and complexity. For standard components from our existing product range, we can typically ship within 7-10 working days. For custom designs, the lead time is usually 15-20 working days after final design approval, including tooling preparation (if needed) and sample validation. We work closely with customers to meet their specific timeline requirements.
