tube end expansion SEA J962 Standard

OUTSTANDING FEATURES AND ADVANTAGE: 1. We execute ISO9001 fully in the company. Besides the Quality System, we use advance quality controlling tools for our quality management and development, like APQP and SPC. You can be reassured that all of our output is meeting the standard and stable in the quality. All items are performed testing before delivery. The deliveries to you will go with a quality report for the dimensions &  material and leakage testing   2. Basing on our bending technic the bending diameter lose is small, with the least tube ovality the tube coils provide the minimum pressure drop to the flow inside the heat exchanger. You can save material cost by reducing the tube size for the same flowing area in another word.   3. Both the coils' diameters and the pitches can be fixed or variable. This allows you to optimized the heat transferring area to your system and increase the heat transferring efficience.    4.There are different types of tube end forming available, like beads, expansion, flaring, reduction/swage and thread cutting directly to the tube parts.   5. We have different type of bending machines and lines to meet your fast delivery request and cost saving strategy. We have CNC bending machines and a number of semi-automatic bending machines which can produce over 10,0000pcs per month. With our tooling ability and technology we can customized the special lines for your high volume commands.   Tube expansions are used to allow a tube to accept internally a mating part and often are used to provide a consistent diameter for press fits, critical brazing applications, etc. Often, a tube expansion is used as a preliminary form, as in an oil filler tube.   Besides the tube end expansion there are also many different of forming design for your application.   Please send you inquiries.  I will reply you as soon as possible.
