- JinHaiは、複雑さとコストを考慮してMOQを決定します：2,000-5,000個；;
Can samples be provided before mass production?
Certainly. JinHai can provide you with 1-5 samples.
Is there a charge for samples?JinHai offers two options for your consideration.
- Simple, low-value samples: If you express strong intent to collaborate with JinHai (typically by providing detailed drawings, clear quantity requirements, and a delivery schedule), we charge 50% of the standard sample price. We commit to deducting this sample cost from the bulk order payment upon subsequent order placement.
- Complex, high-value samples: For products involving hundreds of circuits, specialized connectors, or expensive shielding layers, we charge standard sample fees. However, we commit to refunding the sample cost if your subsequent order exceeds 10 times the sample value.
Sample Lead Time
- Upon receiving your sample request, JinHai will complete sample production within 1-3 weeks and ship it to your location via international express delivery.
Accepted Payment Methods?
At JinHai, we only support three payment methods:
- FOB + 100% advance T/T
- OB + Deposit (30%-50%) + Balance (70%-50%) upon receipt of copy of B/L via T/T
- FOB + Letter of Credit (L/C)
Delivery Lead Times for Custom Orders?
Regarding order cycles, JinHai will clearly communicate order quantities and determine lead times based on order volume. Below are JinHai’s typical lead times for different order quantities:
- Small-batch custom orders (100–500 pieces): Due to lower volumes and the need to procure many raw materials on a spot basis, pre-production preparation takes longer. Lead times typically range from 2 to 5 weeks.
- Large-volume custom orders (over 1,000 units): Due to the large order quantity and significant raw material requirements, some materials are sourced from distributors. This may necessitate adjusting allocation ratios or require factory time for verification. Therefore, the typical production cycle ranges from 8 to 20 weeks. Additionally, the cycle may extend due to special circumstances (e.g., shipping weather conditions, tariff fluctuations).
Are there discounts for bulk orders?
Regarding bulk order discounts, JinHai offers multiple discount options for your selection:
- Direct Price Discount: We provide tiered pricing based on order quantity (e.g., 1K, 5K, 10K, 50K). Unit prices decrease with order volume, offering the most transparent pricing feedback.
- Free Product Allocation: We provide complimentary products based on order quantity. For example, with a 10K order, we include 10 free units as spares.
- Logistics Support: For orders exceeding 5K units, we may cover 20% of local transportation costs (to Chinese customs).
- Engineering Support: While ensuring product performance and reliability, we may utilize more cost-effective materials or implement minor design adjustments, sharing the resulting cost savings with you.
What do I need to get 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.

What is the difference between JinHai technology for wire harness manufacturing?
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.
What are the raw materials for wire harnesses that JinHai uses for manufacturing?
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.
What types of machines does JinHai have?
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
What is fully automated crimping for wire harness manufacturing? How does it work?
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.
What are the advantages of JinHai wire harness manufacturing fully automatic crimping compared with other methods?
- 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.
What does JinHai's wire harness manufacturing inspection process include?
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.
