FAQ
Can we visit your factory?

Of course, we welcome you to visit our factory at any time. Please email or call us to let us know if you have a trip planned.

We offer custom services, and most products are made according to customer drawings and samples, so we can’t provide a complete catalog and price list. If needed, we can offer some standard products and prices for your reference. If you have drawings or samples, we can quickly provide a quote.

We need specific information, such as material, size, thickness, and quantity. Ideally, you can provide drawings. For simple products, sketches are also acceptable.

It depends on the product. For standard products, we usually have stock and can offer a low MOQ. For sheet metal and CNC products, we accept small orders. For metal stamping parts requiring molds, there may be a minimum order requirement.

For standard products, we ship within 1-3 business days after receiving the payment. For products that need mold, the production cycle may take 1-3 weeks. Send us your requirements, drawings, or samples, and we will provide a free quote and delivery time quickly.

We strictly control the quality of raw materials, the production process, and pre-shipment inspections to ensure you receive high-quality products.

Yes, we can handle urgent orders. Our average turnaround time is 2-3 weeks. Our average turnaround time is 2-3 weeks, and if your project is on a tight schedule, we expedite production for you.

Yes, we are happy to provide samples. For standard products, we offer free samples, and we hope you can pay for the shipping. For custom products, we hope you can cover the sample cost and shipping. These costs will be deducted from your official order.

Determined by the material procurement cycle. Samples for commonly used materials are produced within 3-7 days. For special materials, sample delivery times are communicated based on the procurement cycle.

Yes, we mainly customize products based on customer drawings and samples.

Yes, we can add marks or brand logos through stamping, laser marking, or screen printing.

Due to confidentiality agreements with many clients, we cannot display many of the products we have made on our website. Our full range of equipment can produce any sheet metal and stamping products. Please fill out the form and submit it or send an email. You may be surprised!

If you don’t have drawings, just photos or product parameters, we can provide detailed drawings for your confirmation before production.

Please let us know what certifications you need, and we will apply for them according to your requirements.

Wire harness manufacturing is an essential component used in the automotive, motorcycle, agricultural and home electronics sectors.

Wire harness manufacturing is a series of manufacturing technologies that use fully automated manufacturing methods to transform all wire harness raw materials into functional products.

In addition, the crimping process is quite tricky and requires professional skills.

JinHai first completes the final product by manufacturing a variety of raw materials through specialized equipment and assembling by professionals;

JinHai uses different technologies in the wire harness manufacturing process, including fully automatic crimping, pre-assembly, assembly and special equipment testing.

Fully automatic crimping

Fully automatic crimping is the process of crimping the wire and the terminal together. This process is the most core and important process in the entire wire harness manufacturing process.

JinHai manufacturers prefer to use fully automatic crimping equipment, which is fast, convenient and effective.

For terminal crimping, JinHai uses different methods, especially:

  • Fully automatic crimping
  • Semi-automatic crimping
  • Semi-automatic articulation
  • Fully automatic articulation

Pre-Assembly

Pre-assembly is another technique we use when manufacturing wire harnesses. During this process, connectors and terminals can be installed in advance to prepare for subsequent tooling board manufacturing.

JinHai uses professional quality control technology during the pre-assembly process, such as:

  • Grid-based placement of wires with different wire diameters
  • Multiple connectors are placed in grids
  • The plug-in process adopts the process of “one plug, two listen, three pull”

Assembly

Assembly is the key in overall manufacturing technology.

It is the final process of bringing all the harness parts together and positioning and securing them into the finished or manufactured product.

  • Wiring of tooling board
  • Fixing with cable ties on tooling board

Special equipment testing

Special equipment testing is the most necessary process in the entire wire harness manufacturing process.

This process is achieved by using special equipment with anti-terminal pin withdrawal to check whether the wire connection sequence of the wiring harness product is correct.

It can accurately identify whether the plug-in sequence of the wires in the wiring harness is correct and whether the male terminals are plugged in place.

 

Here are some of the most common materials used in custom wire harness manufacturing:

  • Terminals (welding process/copper tin plating/copper nickel plating/copper gold plating/copper silver plating, etc.)
  • Connectors (PA66/PA6/PBT, etc.)
  • Wire (0.75 mm2/1.0 mm2/1.25 mm2/1.5 mm2/2.0 mm2, etc.)
  • Cable ties (PA66/PA6, etc.)
  • Adhesive tape (PVC/BOPP/PET/PE/PP, etc.)
  • Waterproof plug (silicone/EPDM/fluororubber, etc.)

Our manufacturing facility can also process other types of wire harnesses.

 

JinHai uses different machines for wire harness processing. These machines are divided into:

  • Fully automatic crimping equipment
  • Fully automatic assembly equipment
  • C-type winding machine
  • Mobile tooling board
  • Special electrical test bench

 

The process allows the wire to be delivered to the equipment through a wire feeding device, and the terminal and the wire are connected together by crimping. During this process, the crimping status is monitored in real time by a pressure monitoring device to ensure that each product achieves stable quality. .

Fully automatic crimping replaces traditional manual crimping, which is faster, more efficient and more accurate. During the fully automatic crimping process, the automation equipment cooperates with the pressure monitoring device to monitor the crimping status in real time.

In addition, due to these and other advantages, fully automatic crimping technology is suitable for a wide range of crimping applications.

  • Fast and effective.
  • It reduces the risk of insufficient tension and crimp height deviation in manual crimping.
  • The crimping process is more stable.
  • Each wire is crimped sufficiently to exceed the crimping condition of a hand crimp.
  • High cost performance.

Our experienced inspection team starts with the inspection process.

The factory operators verify the product against the prescribed operation documents and inspection documents before commencing operations.

Once the factory operators have manufactured the product to specifications, the product is taken to the inspection area where professional quality department inspectors check whether the product is acceptable.

Here are some benefits of wire harness manufacturing:

  • Harness is a broad term that covers a wide variety of materials.
  • Wiring harnesses offer a wide range of design possibilities.
  • It allows for more customizable settings.
  • The manufacturing process of wire harness is very demanding, which makes the wire harness products have higher quality.
  • The harness is easy to transport, process and install due to its light weight and flexible features.
  • It is low cost, high quality, light weight, more flexible and cost effective.
  • Wire harness manufacturing can be widely used in various industries.
