Improve Technology - Powder coating - new machine

  We Comfy don't stop our steps to provide better quality.

  We buy "shot blasting machine", and install it today.

  Btw, thanks for machine factory help us so much.

  This machine will help table quality so much.

  1. Iron pipe internal will be almost not rust.

  2. The powder coating will be very strong on the frame, not easy to drop down.

  3. We almost will not use Phosphating water, proud to protect the environment.

  Shot blasting machine, the use of high-speed projectiles thrown Blasting cleaning or strengthen the casting surface of the casting equipment. Shot function while casting off the sand ﹑ addition to core and cleanup.

  Shot by shot blasting machine Shot speed thrown down the grit material impact on the kind of surface treatment technology. Compared to other surface treatment technology, it is faster, more efficient, and on the part of the reservation after the casting process or punching.

  1930s American companies in the world made the first shot blasting machine. China s shot peening equipment production began in the 1950s, mainly imitation of the former Soviet technology.

  Shot blasting machine can also be used to remove burrs, scale, and rust that may affect the integrity of the object parts, appearance, or definition. The blasting machine can also be a part of the surface of the coating for the removal of surface contaminants, and to increase adhesion of the coating to provide a surface profile of the workpiece to achieve the purpose of strengthening.

  Blasting machine shot blasting machine is different in that it is used to reduce the fatigue life of components of different surface stress increases, increasing the strength of the part, or to prevent fretting.

  Surface cleaning

  The blasting device first used in foundry industry steel cast iron surface sticky sand and oxide removal.

  Almost all steel castings, gray castings, malleable iron fittings, ductile iron, etc. should be shot blasting. This is not only to remove the surface oxide and sticky casting sand, casting quality is also indispensable before the test preparation step, such as large gas turbine casing during the NDT throw must be strict before blasting, in order to ensure the testing results in reliability. In general, the production of castings, cast blasting is found casting surface defects such as skin pores, slag hole and sticky sand, cold shuts, peeling and other essential means of technology. Non-ferrous metal castings, such as aluminum alloy, copper alloy surface cleaning, in addition to descaling and found the casting surface defects, but also the main purpose is to throw shot to clear the die casting burrs and obtain a sense of the surface quality decor obtain comprehensive results. Metallurgical steel production, cast steel blasting or pickling is guaranteed to obtain high productivity in mass production and the use of mechanical or chemical combination to the skin A process phosphorus. Silicon steel sheet, stainless steel sheet, and other steel plates, with the production, in the cold rolling step process, must be carried out blasting or pickling after annealing treatment to ensure the cold-rolled steel sheet surface roughness and thickness accuracy.

  Work to strengthen

  According to modern metal strength theory, increasing the dislocation density within the metal is to improve the strength of the main direction of the metal. The practice has proved that the metal shot blasting is to increase the dislocation structure effective process method. Which for some metals can not be hardened through the phase change ( such as martensitic hardening, etc.) or implemented on the basis of the phase transformation hardening and requires further strengthening of the workpiece, the more a very important significance. Aviation, aerospace industry, automotive, tractor and other parts required lightweight, but increasingly high-reliability requirements, the important measure is the use of technology to improve member throwing shot peening strength and fatigue strength.
