Top Industrial Connector Manufacturer in China

Whether it is aluminum alloy molds, zinc alloy molds or plastic molds, WPCONNECTOR has its own mold production workshop, which can complete the development of new products in 7 to 10 days.

Can produce all plastic shells and related accessories.

Produce all zinc alloy and aluminum alloy shells and related accessories. Equipped with automatic trim die machines.

Process copper pin and contact and related accessories, the error is controlled at less than 1C (1/100mm).

can process all metal parts and related accessories such as copper, aluminum alloy, zinc alloy, etc.

56 units, which can automatically assemble various types of industrial connectors, including industrial plugs and sockets, circular connectors, heavy duty connectors, cable assemblies and connector accessories.

Test the performance of each copper pin and contact to ensure that it meets the requirements of power, signal and data.

WPCONNECTOR have their own electroplating and surface treatment workshop, maintain the high quality standard, especially the silver and gold plating of copper pin and contacts, which fully meet the requirements.

WPconnector started from a small factory and is currently the largest manufacturer of industrial connectors in China. WPconnector continuously improves production facilities, increases investment in research and development, and finally implements independent production and independent control of each production line, and has full test and inspection to ensure that each industrial connector is the best quality, so that customers can use it with confidence and happiness.

One-touch image size tester automatic measurement on up to 300 part features in seconds, provides accurate and repeatable measurements instantly.

In the electroplating industry, thickness is measured on the scale of microinches. One microinch [µin] is equivalent to 1 millionth of an inch. Contact and connector parts must meet thickness requirements called out in MIL or ASTM specifications, and it’s imperative that minimum thicknesses are met without over-plating.

WPconnector applies automatic electroplating measurement to ensure the quality of connectors.

Our connectors undergo vibration tests to assess the mechanical and electrical stability and its performance depending on the applications for which it was originally designed. it will test the connection between:

– pin and socket
– wire and termination
– contact flanges and retention clips
– retention clip and cavity of the insert
– the plug and the receptacle through the locking system.

Our plug and socket undergo a rigorous lifetime testing process, which ensures that connectors are durable enough to withstand temperature extremes, use cycles, and other operating conditions.
During burn-in process, the component endures extreme operating conditions, including temperature extremes, high use cycles, and high voltages to eliminate defective components.

In glow wire tests, a glowing wire is used to simulate ignition source, to simulate heating effects that may arise in malfunctioning electrical equipment caused by an overloaded connection or component that is overheating.
The goal is to analyze the tendency of a connector’s plastic material to catch fire when wires are overloaded. Raw materials and products will undergo glow wire testing.

Waterproof connectors have a high IP (Ingress Protection) rating, including dust and water submersion resistance and protection from high-pressure water flow. Each of our connectors will go through rigorous waterproof testing to make sure it reachs its IP rating level.

All raw material will be tested in our own lab, the equipment we have:
– UV Testing Machine
– Aging Machine
– Creepage Trace Testing Machine
– Glow-wire Testing Machine
– UL Combustion Tester

– IPX3-6 Comprehensive Water-proof Rating Test Chamber
– IPX4-IPX6 Water-proof Testing Machine
– IPX7-8 Water-proof Testing Machine
– Plug and Socket Life Testing Machine
– Temperature Rise Tester
– Vibration Test machine
