Electrical Connector Manufacturing Process

Our integrated 7-step production process ensures every connector meets the highest quality standards. From precision mold-making to final testing, we control every stage in-house for guaranteed reliability and fast delivery.

01 Mold Department - the foundation of everything we make

Plastic Mold Section:
These are our high-precision injection molds for connector housings, sealing rings, and insulator components. Each mold is manufactured to ±0.05mm tolerance using hardened steel that can withstand millions of injection cycles.

Hardware Mold Section:
Here we create the progressive stamping dies for our metal contacts and terminals. These molds shape brass and phosphor bronze into precise contact pins, socket terminals, and grounding components. The die design determines the spring properties and electrical performance of every contact.

02 Injection Molding Department

Our injection molding machines range from 120 to 210 tons, allowing us to produce everything from tiny sealing gaskets to large junction box housings. We use specialized thermoplastics – PA66, PBT, and TPE materials – all formulated for IP68 waterproof performance. Each machine monitors 12 parameters in real-time: temperature, pressure, injection speed, and cooling time.

03 Hardware Stamping Department.

These machines, from 25 to 110 tons, create all our electrical contacts. The stamping process is critical – we’re not just cutting metal, we’re forming the spring characteristics that ensure reliable electrical contact over thousands of mating cycles. Each contact goes through multiple forming stages: blanking, bending, coining, and final shaping.

04 Automated Assembly Department

Automatic Assembly Machines:
These handle high-volume contact insertion, housing assembly, and seal installation. Each machine can assemble 2,000-3,000 pieces per hour with consistent quality.

Potting/Sealing Machines:
Our automated potting machines inject precise amounts of waterproof sealant into each connector. This creates the hermetic seal that achieves IP68 protection.

Riveting Machines:
These machines permanently secure contacts to housings using controlled force riveting, ensuring mechanical and electrical integrity that won’t degrade over time.

05 We operate 7 manual assembly production lines for customized products and quality control:

Final Assembly Stations:
Workers perform final connector assembly, cable attachment, and customization according to your specifications.

Quality Control Checkpoints:
Every 50th unit undergoes insertion force testing, visual inspection, and electrical continuity checks.

Packaging Department:
Products are packaged in anti-static bags with moisture absorbers, labeled according to your requirements, and prepared for shipment.Packaging Department: Products are packaged in anti-static bags with moisture absorbers, labeled according to your requirements, and prepared for shipment.

06 Our comprehensive testing ensures each connector will perform in real-world conditions:

IP68 Waterproof Testing: 1.5-meter water submersion for 30 minutes minimum
Thermal Cycling: -40°C to +105°C temperature extremes
Electrical Performance: Insulation resistance, dielectric strength, contact resistance
Mechanical Durability: 500+ mating cycles, vibration resistance
Chemical Resistance: Exposure to UV, salt spray, and industrial chemicals

07 Finished Goods Warehouse and Component Storage.

Finished Goods Warehouse:
Climate-controlled storage with full traceability. Each lot is tracked from raw materials through final shipment, so we can provide complete quality documentation with every order.

Component Warehouse:
We maintain strategic inventory of contacts, housings, seals, and cables to ensure quick turnaround times. Our ERP system automatically triggers reorders to prevent production delays.
