Technological details

一、Assemble
Assembling is the first step also the most complicated one. At first mixing various mental powder with diamond equally，then put the mixed powder into graphite mould and equipped with relative steel substrate, forwarding to sinter position.

二、Sintering

·         Sinter is adopt powder metallurgy method，The assembled products are sintered at high temperature and high pressure. Meanwhile select corresponding technical parameter based on the product specification, rigidity and formula to achieve different character to meet different construction requirement.

三、 Heat preservation and cooling 
Sinter temperature is under 600-1100℃, sinter product can’t cooling too fast to avoid shrink unevenly on different part consequently crackle. The best way is put into heat insulated box for cooling slowly to guarantee the quality.
四、Demould  
 The product can be demoulded after cooling for 10-12 hours till the product reach room temperature，then paint different color for distinguish as plan.
五、Machining

·          The product is first turned on a common lathe, then forward to CNC lathe for fine turning. Drawings need to be carefully compared during processing or select corresponding technology, After processing seriously test the size of the product with relevant measuring tools, unqualified one need to be rework or for waste disposal.

六  六、Water gap process

·         This process is to use grinder and slotting machine to process the inside and outside of the product and the middle part of the water tank, three parts of the gap are accurately machined according to the specification.

七、Sandblasting treatment is to use sandblasting equipment to remove rust on the body and matrix parts of the product to become bright.
八、Printing anti-counterfeiting codes is to use laser jet coding equipment and pneumatic coding equipment to print the combination of numbers and letters in a specific position, each code is an identify can trace the product by this code.

九、Painting process is painting different color according to the hardness chromatographic table to prevent from rust and continent to selection.

十、Rust prevention is the part of product base screw and inner diameter without painting should be sprayed with anti-rust oil

十一﹑Labelling the products accordingly, package and put in storage.
