High - Performance No. 45 Steel Needle (44.5mm, Glue - injected) for Air

Product Specification

1. Product Materials

2. Technical Requirements

1. Electrical Insulation: The product must meet strict electrical insulation requirements. The insulation resistance between the steel and iron components should be 1000MΩ at 1000VDC. It can withstand a high - voltage test of 3000VAC at 50Hz for 1 minute, with a maximum leakage current not exceeding 0.5mA. No electrical breakdown or flashover is allowed during this test, ensuring reliable electrical isolation.
2. Gas Tightness: It is designed to withstand a nitrogen pressure of 3.5MPa without leakage. This high - level gas tightness is crucial for applications where maintaining a sealed environment is necessary, such as in certain electrical devices.
3. Current - Carrying Capacity: The steel parts of the terminal can endure a maximum current of 30A under short - circuit conditions and 25A during normal operation. This ensures stable electrical conductivity and reliable performance in different electrical load scenarios.
4. Surface Treatment: The product's surface is electroplated with a thickness of 3 - 5 microns (for welding areas). This electroplating not only enhances corrosion resistance but also improves the product's appearance and welding performance.
5. Operating Temperature: The terminal is suitable for normal operation within a wide temperature range from - 40°C to 150°C. It can maintain its mechanical and electrical properties within this temperature interval, making it adaptable to diverse working environments.

3. Quality Assurance

1. Precision Manufacturing: All dimensions of the product are strictly controlled. The linear tolerance is ±0.13mm, and the angular tolerance is ±0.5°. The dimensional accuracy is interpreted in accordance with ASME Y14.5 - 2018 standards, ensuring a high - precision fit with other components.
2. Rigorous Testing: Every product undergoes a series of comprehensive tests, including electrical performance tests, gas tightness tests, and surface finish inspections. Only products that pass all these tests are qualified for release, guaranteeing product quality and reliability.
3. Quality Management System: Our company adheres to a strict quality management system. From raw material procurement to product delivery, every step is carefully monitored and controlled to ensure that the product meets or exceeds industry standards.

4. Foreign Trade Transportation

1. Express Delivery: For small - quantity orders or urgent requirements, we offer express delivery services such as DHL, FedEx, and UPS. These services provide fast transit times, usually delivering the products within 3 - 5 working days. This allows customers to receive their products promptly and start using them without delay.
2. Sea Freight: For large - quantity orders, sea freight is a more cost - effective option. We cooperate with well - known shipping companies to ensure the safe and timely transportation of products. The products are carefully packaged with appropriate cushioning materials and secure packaging boxes to prevent damage during long - distance sea transportation.

5. Foreign Trade Transaction Methods

1. Order Placement: Customers can place orders through our official trading platform on hermetic terminal or by sending detailed order information via email. Our professional sales team will respond promptly to confirm the order details, including product specifications, quantity, and delivery address.
2. Payment Terms: We support multiple payment methods for the convenience of our customers. T/T (Telegraphic Transfer) is a commonly used method, where customers transfer the payment directly to our designated bank account. For customers who prefer a more secure payment method, especially for large - value transactions, we also accept L/C (Letter of Credit). Additionally, for small - value transactions, we support payment through third - party platforms like PayPal, which offers quick and convenient payment processing.
