junxiang auto Engine Coolant Radiator Hose for E70 F15 F16 oem 64219124729

EPDM rubber tube is formed by microwave vulcanization process, the surface is smooth and beautiful, with good elasticity and compression deformation, weather resistance, ozone resistance, chemical resistance and wide temperature range (-40 °C~ Excellent performance such as +120 ° C) has been widely used in manufacturing industries such as automobile industry machinery. For different shapes, different materials, and products with special performance requirements, it can meet the needs of design and use.
Oil-resistant hose: also known as NBR nitrile rubber hose, because it does not react with strong oil, it is commonly used in fuel tanks and other parts, transporting diesel, gasoline, water, kerosene and lubricating oil hydraulic oil, engine oil and other media, outstanding oil resistance.

TESTING EQUIPPMENTS

How we guarantee our quality?
1. For EPDM rubber, we purchase the raw rubber produced from the factory in Taiwan. The quality is preferred and the quality of the original rubber can be guaranteed for a long time. We purchase raw rubber directly from the factory to check whether the quality of the rubber raw materials meets our requirements, and our procurement costs will be low without the distributor's wholesale.
2 The water pipe products we produce have a glue content of 40-45%, and the product has high durability and high anti-aging.
3 We use the inner line produced by the domestic joint venture factory, the material is spun. Spun is the material used to produce bulletproof vests. The water pressure control of our water pipes is controlled within the range of 2-5 KPA, which guarantees that the car can be driven in extreme environments. Under the great pressure, our water pipes can also be used smoothly without bursting.
4 plastic joint molds are developed by Junxiang Company. It is entrusted to mold molds for auto parts supporting enterprises, which will inevitably guarantee the precision of the molds and directly affect the appearance and precision of the finished plastic joints, which is close to the original water pipes. Quality status. At the same time, our company uses PA66 raw materials produced by DuPont.
5 Before mass production, our company passed the proofing, testing the rubber content of the sample, the shrinkage ratio and other physical properties.
In the production process, the size, aperture, angle, etc. of the product are controlled by tooling, and the root is detected. The test contents include: length, angle, whether the joint degree of the plastic joint and the rubber tube meets the requirements of the drawing, and whether the accessory has a leak band or a multi-belt (example: clamp), if there is no problem, use a paint pen as a mark on the key part. . After the sample quality is passed, mass production is carried out. After the product is tested, it is put into the next process and packaged.
