Product Description

1. Product Materials

2. Technical Requirements

1. Surface Finish: As mentioned before, no burrs are permitted on the product. This ensures smooth operation and prevents potential damage to other components or users.
2. Leak - tightness: The product must pass a leak test at 4MPa without any leakage. This is crucial for applications where a sealed environment is required, such as in electrical enclosures to protect internal components from moisture and dust.
3. Electrical Insulation: The insulator resistance should be 1000MΩ at 500VDC. This high - resistance value guarantees effective electrical isolation between different parts of the product, reducing the risk of short - circuits and ensuring user safety.
4. High - Potential Test: During the Hi - Pot test at 2000VAC for 2 seconds, the maximum leakage current should not exceed 0.5mA, and there should be no breakdown or flashover. This test verifies the product's ability to withstand high - voltage stress and maintain its electrical integrity.
5. Tabs Torque Resistance: The tabs should be able to withstand a torque of 45kgf.cm without detaching from the pin. This ensures a secure connection between the tabs and the pin, which is essential for reliable electrical and mechanical performance.

3. Quality Assurance

1. Raw Material Inspection: We source raw materials from reliable suppliers and conduct strict inspections upon arrival. For Q355B plates, we check the chemical composition and mechanical properties to ensure they meet the required standards. The SUH446 stainless - steel pins are inspected for their corrosion resistance and dimensional accuracy. ELAN #48 glass is examined for any defects that could affect its electrical insulation properties, and the SPC tabs are inspected for flatness and surface quality before nickel - plating.
2. In - Process Quality Control: Throughout the manufacturing process, we implement multiple quality control checkpoints. We monitor the forming and machining processes of the plate, pins, and tabs to ensure dimensional accuracy. The nickel - plating process is carefully controlled to achieve the required thickness and uniform coating. The assembly process is also monitored to ensure proper alignment and connection of all components.
3. Final Product Testing: Every finished product undergoes a comprehensive series of tests. In addition to the leak test, insulator resistance test, Hi - Pot test, and tabs torque test, we also conduct visual inspections to check for any visible defects. Only products that pass all these tests are considered suitable for shipment, ensuring that our customers receive high - quality and reliable products.

4. Foreign Trade Transportation

1. Express Shipping: For small - quantity orders or urgent requirements, we offer express shipping services via well - known courier companies like DHL, FedEx, and UPS. These services typically deliver within 3 - 5 business days, allowing you to receive your products quickly and start using them without delay.
2. Sea Freight: For large - quantity orders, sea freight is a more cost - effective option. We work with reliable shipping lines and use proper packaging materials to ensure the safe transportation of products. The products are carefully packed in sturdy boxes with cushioning materials to protect them from damage during transit.

5. Foreign Trade Transaction Methods

1. Order Placement: You can place orders through our official trading platform on terminal. The platform provides a user - friendly interface where you can select the product specifications, quantity, and delivery address. Alternatively, you can send us an email with your order details. Our sales team will respond promptly to confirm the order and provide you with all the necessary information.
2. Payment Terms: We support various payment methods to accommodate your needs. Telegraphic Transfer (T/T) is a common and straightforward payment method. You can transfer the payment directly to our designated bank account. For larger transactions, we also accept Letters of Credit (L/C) to ensure a secure payment process. Additionally, we are open to discussing other payment options based on your specific requirements.
