2.Glass beads Picture





 

Glass bead blasting is essentially applying fine glass beads of various sizes at varying degrees of pressure. Smaller glass spheres result in a smoother surface while larger spheres produce a more textured finish.

4.Glass beads Applications

Glass beads do not remove any of the base metal or imbed the surface. It will produce a better, more uniform finish while also adding sheen or brightness to the part.
It has a variety of applications, including:
• Finishing: Can be used on a wide range of materials, including metals, glass, plastic and rubber. 
• Cleaning: Without causing a dimensional surface change, glass bead blasting removes/cleans foreign substances.
• Deburring: In order to assemble and operate parts, corners and edges may need to be deburred. Glass bead blasting can remove burrs and feathered edges while ensuring no base metal from the surface is removed.
• Peening: Peening extends the life of metal parts by combating stress cracks and corrosion. 

5.quality control

A.raw materials
All raw materials are qualified products with product testing reports. 

B. molding 
In the production process, molding is the key of product quality . On the furnace temperature control, the number of units and raw materials scattered uniformity, the introduction of wind and other equipment in strict accordance with the operating procedures.

C.annealing
annealing is the necessary way to improve the strength of the product, the temperature is critical. We strictly according to set temperature, the annealing speed can not be fast, nor slow, to ensure the timeliness of the annealing process.

D.test 
We use advanced detection equipment, to control the step quality , substandard products can not be stored. 
All the product reach international standard , like European EN1423 and 1424, the United States AASHTO M247, the British BS6088, Japan JIS R3301, South Korea KS L2521 and other requirements.
