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'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 ...

What is 'Catch hook and thin-wall' of plastic mold products?

What is 'Catch hook and thin-wall' of  plastic mold products ?​ 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe.  Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall What is the big problem about thin wall? The binding point is particularly easy to press and brittle, Then could't pass the test. It will be difficult to assemble in the next step, The product will be uneven filling, shrink, and easy broken.

Useful Tips for Custom Titanium Manufacturing

  JY Machinery offers high-quality precision and cost-effective CNC machining services for   custom titanium parts   to enhance manufacturing efficiency. Custom Titanium alloy manufacturing is mainly used for the production of aircraft engine compressor components, followed by the structural parts of rockets, missiles and high-speed aircraft, and related medical accessories. The density of titanium alloy is generally about 4.51g/cm3, which is only 60% of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structural materials, and parts with high unit strength, good rigidity and light weight can be produced. The aircraft's engine components, skeleton, skin, fasteners and landing gear all use titanium alloys. The Reasons Why Titanium Is Hard to Machine If you want t...
