Our workshop constantly perfects customersí» information system, and establishes complete national customer profiles, so that it is easy to make the comprehensive inquiry and quality analysis of service, and pay a return visit to customers. For the purpose of improving customersí» satisfaction we provide customers with fast after-sale service.
3. Vacuum brazing processing business, vacuum heat treatment and vacuum brazing technology service, repair and alteration of vacuum furnace, supply of vacuum furnace parts, training service of vacuum furnace technology.
Our workshop has a strong capacity of vacuum brazing and heat treatment processing, maximum vacuum brazing 6000 (L) ?1200 (W) ?1200 (H), so we can undertake a variety of vacuum brazing, vacuum heat treatment processing business and service. We can apply vacuum brazing to the same metal, the different kinds of metal, the metal and nonmetal, and realize effective vacuum brazing connection, and can solve production problems for customers. Our workshop can accept the business of apply vacuum brazing and vacuum heat treatment to the diamond, carbide, ceramics, steel, high temperature alloys, titanium alloy, perm alloy and other materials, and can accept the business of apply vacuum sintering to magnetic materials, powder metallurgy materials and other types of processing.
4. Research and production of special vacuum solder.
Our workshop research and produce various SMT solder paste, SMT lead-free solder paste, copper solder paste, aluminum solder paste, nickel solder paste, silver solder paste, which apply to vacuum brazing, gas protection brazing, torch brazing, resistance brazing, high frequency brazing and so on, involving in various carbon steel, stainless steel, high temperature alloy, diamond, various copper alloy, aluminum alloy, hard alloy and so on. For example, applying vacuum sealing to products of stainless steel vacuum flask, stainless steel vacuum coffee pot, vacuum insulated container, has characters of high quality with low price, low melting point, the best activity and moisture, and can increase the reliability of vacuum brazing, enable customers obtain considerable economic benefits. Our vacuum brazing technology has been extensively used in the fields of aviation, communications, automotive, light industry, mechanical and electrical, refrigeration, medical equipment, radiators, heat exchangers, coolers, etc.
5. Supply of various vacuum furnaces

Cai Dongjun vacuum brazing workshop is credible, honest, strong, welcome all friends to negotiate business, and exchange technology and experience.
We hope that our sincerity and strength can win your greatest satisfaction!

1. 60% or 80%? What is the vacuum brazing passing rate or the second passing rate of your vacuum oil radiator? At present vacuum brazing seal-type oil radiators require high pressure resistance and good heat dissipation nature, some require to meet the hybrid cooling requirement, which mixes the hydraulic oil, variable moment oil, engine oil and so on. The passing rate of products in common enterprises is not ideal, resulted in returning to repair, even being declared worthless. Our workshop made further research in the past 20 years of practice, and achieved new breakthrough which bring the passing rate of products to a new height. It is predicted that the application of this technology can bring vacuum brazing seal-type oil radiators into a new era. Patent application can be carried out. The radiator factory and aluminum factory which have the intention of cooperation contact us, please.
2. Our workshop has big technology strength, and owns a lot of senior scholars and experts engaged in product development and undertaking project for many years. They are good at designing stainless steel oil cooler, aluminum oil cooler, aluminum oil radiator, aluminum water tank, aluminum intercooler, copper water tank, etc. They are familiar with production process and manufacturing process control.
3. Our technology objectives are 100%. According to industry surveys, enterprises have a certain degree of manufacturing competitiveness if its passing rate of production reaches the following level.
1) The passing rate of stainless steel oil cooler is 97%;
2) Aluminum oil cooler is 80% (Few domestic enterprises can achieve it, because the technical difficulty is big, mostly foreign products);
3) Aluminum oil radiator is 80% (Using the above techniques can increased by 10 percentage points or more);
4) Aluminum water tank is 90%;
5) Aluminum intercooler is 95%;
6) The second passing rate of copper water tank is 99%.



That the passing rate of products remains at a level shows enterprises reach the limit point, only break the limit point can enterprises get benefit. The more small lifting space becomes, the more big technical difficulty becomes. The pursuit is ending, only having dreams of pursuit can we have the motivation of advancing. Believe in our team, as long as giving us a platform of cooperation, we are likely to create success. Something is unexpected, but nothing is impossible. We expect cooperation with you! We look forward to sharing success and delight of cooperation with you!
