PVD (physical vapor deposition) coating is a type of Surface Treatment that is used to improve the performance of metal parts, by applying a thin layer of material onto the substrate through a vacuum chamber. This process provides a range of benefits, including increased hardness, improved wear resistance, and enhanced corrosion resistance.
PVD coatings are typically applied to metals such as stainless steel, titanium, and aluminum. They are particularly useful in applications where the substrate is subjected to high wear and tear, as the coatings help to reduce friction and limit the damage caused by abrasion. They are also used in the automotive industry to provide an aesthetic and functional finish to exterior parts.
PVD coatings can be tailored to meet specific application requirements, with a range of coating materials available, including titanium, chromium, and zirconium. These coatings can be deposited in a range of colors, such as black, gold, and silver, giving designers and manufacturers the flexibility to create parts with the desired appearance.
Another key benefit of PVD coating is its durability. The thin layer of coating can offer a long-lasting, high-performance finish, even in harsh or corrosive environments. This makes them particularly useful in outdoor applications, and in settings such as aerospace and medical devices, where reliability and durability are critical.
PVD coating is applied through a series of steps, including cleaning and pre-treatment of the substrate, coating material deposition, and post-treatment, such as polishing or annealing. The result is a thin, uniform layer of coating that provides a range of functional and aesthetic benefits.
In conclusion, PVD coating is a versatile and effective surface treatment for metal parts. It offers a range of benefits, including improved hardness, wear resistance, and corrosion resistance, as well as aesthetic options. By enhancing the performance and durability of metal parts, PVD coating plays an important role in improving the reliability and efficiency of a range of industries and applications.

There are many types of shot blasting equipment, and different types of equipment are suitable for different types of shot blasting workpieces and technical requirements. The selection of different shot blasting equipment according to the different workpieces is an important step to ensure that the workpiece cleaning effect achieves the corresponding surface roughness and cleanliness.
For the foundry industry, the determination of the shot blasting method and equipment should be specifically considered in conjunction with the material, hardness, shape and shot blasting technical requirements of the workpiece, as well as the production tools of the previous process.
When selecting specifically, you should first select equipment with high efficiency and low energy consumption. When the output is large, it is conceivable to select equipment without two or more sets of carriers to reduce the auxiliary time, increase the production efficiency and reduce the labor intensity of the workers.
The types of workpieces applicable to different types of shot blasting equipment in China are as follows:
1. Q34, Q37, Q75 series hook type shot blasting machine: It has a wide range of applications, especially for all kinds of thin-walled parts that are afraid of bumping or long parts. It is suitable for multi-variety and small-volume production, such as highway guardrails. , all kinds of pipe fittings valves, all kinds of gold welding parts, all kinds of cast iron steel castings and non-ferrous metal parts.
2. Q26, Q36, Q76, Q77 series trolley type shot blasting machine: suitable for cleaning or falling sand of all kinds of medium and large or heavy cast steel castings. The weight of the platform is between 5 and 75 tons. The spray is combined in a way.
3. Q35 series rotary shot blasting machine: suitable for cleaning or shot peening of small and medium-sized parts and flat parts in thin wall or easy to break.
4. Q38, Q48, Q58 series catenary type shot blasting machine: suitable for mass production of small and medium-sized castings, currently widely used in automobiles, tractors, diesel engines and valves.
5. Q31, Q33, Q61 series drum type shot blasting machine: suitable for large and medium-sized workshops to clean up less complex, not afraid of bumps, large output workpieces.
6. Q32, Q62 series crawler shot blasting machine: suitable for cleaning small and medium castings in single or batch production.
7. Q39, Q69 series roller pass type shot blasting machine: suitable for cleaning small and medium-sized batches or flat parts. At present, it is more used for shot blasting of steel plates and profiles including H-shaped steel.
8. QS212 (A) squirrel cage shot blasting machine: suitable for mass production of complex parts, such as engine cylinder heads, all kinds of gear shifting.
9. Robotic shot blasting machine: high production efficiency, good cleaning quality, high degree of automation, and cleaning of batch castings.
10. All kinds of special equipment: such as liquefied gas cylinder shot blasting machine, spring shot blasting machine, etc.
11. Combined shot blasting machine: hook type trolley combined shot blasting machine.
In summary, at present, the domestic shot blasting machine manufacturing industry is in a period of prosperous development, and its application fields are constantly expanding. The automation of the equipment is getting higher and higher, and the proportion of non-standard equipment suitable for the special requirements of users is increasing.
The rapid development of shot blasting technology will bring new vitality and vitality to China's basic equipment industry.
How to choose the right shot blasting equipment
The choice of cleaning equipment should be based on different shot blasting parts, and the appropriate shot blasting equipment should be selected.
