The application range of sandblasting treatment

Sandblasting is the process of cleaning and roughening the substrate surface by the impact of high-speed sand flow. Use compressed air as the power to form a high-speed jet beam to spray the blasting material (copper ore, quartz sand, corundum, iron sand, Hainan sand) at high speed on the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece surface changes.
(1) Workpiece coating and sandblasting before workpiece bonding can remove all dirt such as rust on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (the so-called rough surface). By changing the abrasives with different particle sizes, the roughness of different degrees is achieved, which greatly improves the binding force of the workpiece with coatings and plating materials. Or make the adhesive bond more firm and better quality.
(2) The rough surface of the casting, the cleaning and polishing of the workpiece after heat treatment can clean all the dirt (such as oxide scale, oil and other residues) on the surface of the casting and forging, and the workpiece after heat treatment, and polish the surface of the workpiece to improve the smoothness of the workpiece. The workpiece is exposed to a uniform metallic nature, which makes the appearance of the workpiece more beautiful and beautiful.
(3) The burr cleaning and surface beautification of machined parts can clean the tiny burrs on the surface of the workpiece and make the surface of the workpiece more flat, eliminating the harm of burrs and improving the grade of the workpiece. And sandblasting can make small rounded corners at the interface of the workpiece surface, making the workpiece more beautiful and more precise.
(4) Improve the mechanical properties of parts. After sand blasting, mechanical parts can produce uniform and fine uneven surfaces on the surface of the parts, so that the lubricant can be stored, thereby improving the lubrication conditions, reducing noise and increasing the service life of the machine.
(5) Gloss effect for some special-purpose workpieces, sand blasting can achieve different reflection or matte at will. Such as stainless steel workpieces, plastics polishing, jade polishing, wooden furniture surface matte, pattern on the surface of frosted glass, and the surface of the cloth and so on.

What is Guide Pin ?

  1.Definition of guide pin The  guide pin  is a guide element used in the mold in combination with the components to ensure that the mold moves and guides the mold stroke with precise positioning. They are generally cylindrical with shoulders and usually have oil grooves. 2.The material of the guide pin The material of the  guide pin  is generally selected from bearing steel, hot work die steel, easy car iron, etc., and the use of bearing steel SUJ2 is larger, which greatly enhances the durability and interchangeability of the guide post in terms of guiding performance. The guide post and components constitute the outer guide post component and the inner guide post component, which have a beautiful metallic luster. Heat treatment of guide post: HRC58-62; surface roughness of guide post: Ra0.8, Ra1.6. 3.Center hole of guide pin The roundness of the  guide pin  is very demanding. The central hole is mainly used to grind the outer diameter with a cylindr...

What's the properties of POM?

  Polyformaldehyde (POM) thermoplastic crystalline polymer. Known as "Super Steel" or "Sai Steel", The English abbreviation is POM. Generally, polymers obtained by formaldehyde polymerization have a low degree of polymerization and are easily thermally depolymerized. It can be used as a raw material for organic chemicals and synthetic resins, and as a fumigant for drugs. 1.General property POM  is a hard, dense material with a smooth surface and gloss, light yellow or white, thin-walled partly translucent. Combustion characteristics are easy to burn, and continue to burn after leaving the ignition source. The flame is yellow at the upper end and blue at the lower end. Melting dripping occurs and has a strong pungent formaldehyde smell and fishy smell. POM is white powder, usually opaque, good coloring, specific gravity 1.41-1.43 g/cm3, molding shrinkage 1.2-3.0%, molding temperature 170-200℃, drying conditions 80-90℃ for 2 hours. POM's long-term heat resistance ...

Precision CNC Milling Service: What Factors Affect CNC Machining Cost?

  How to save CNC milling costs? Why some custom  CNC milling services  are expensive? Firstly, we may need to know the cost factors for CNC milling services. 1)Stock Material As with any type of manufacturing, Stock material is the most basic cost. Some materials are more difficult to process than others, and some materials are more expensive as raw materials. The processing speed of some materials is much slower than others, even with the advancement of modern tools and mechanical technology. Some materials can wear out the expensive consumable cutting tools used more quickly, and can vary from one tool that makes hundreds or even thousands of parts to one part consuming multiple tools.Therefore, the material selection of your components can be a huge cost factor. 2)The Specification of  CNC Machining Parts The size and overall geometry of the parts are of course important factors in the quotation of machining operations. Obviously, the larger the physical part, th...
