For copper products, the following types of sandblasting machines can be considered:

A, suction dry sandblasting machine

principle of operation

The compressed air flows in the spray gun at a high speed to form a negative pressure, and the abrasive is sucked into the spray gun from the sand tank by the ejector action, and then the abrasive is sprayed on the surface of the copper piece at a high speed by the compressed air, so as to achieve the purposes of cleaning, derusting, descaling and the like.

Features and applicable scenarios

Simple structure, relatively low price and convenient operation and maintenance.

Suitable for surface treatment of small copper parts, such as copper handicrafts and small hardware accessories. It is suitable for copper parts with small batch and not particularly high requirements for surface treatment.

Second, the press-in dry sandblasting machine

principle of operation

Using compressed air as power, the pressure is established in the pressure tank by compressed air, and the abrasive is pressed into the spray gun, and then sprayed on the surface of copper at high speed.

Features and applicable scenarios

The sandblasting efficiency is high, and the abrasive conveying is stable, which can be applied to large copper parts or mass production.

It can handle copper parts with various shapes and sizes, and is suitable for copper parts with high surface requirements and need to quickly remove a large amount of oxide scale or corrosion, such as large copper castings and copper pipelines.

Third, the liquid sandblasting machine

principle of operation

With the grinding liquid pump and compressed air as the power, grinding liquid (mixed liquid of water and abrasive) is sprayed on the surface of copper parts at high speed through a spray gun.

Features and applicable scenarios

Compared with dry sandblasting machine, liquid sandblasting machine produces less dust, which is more friendly to the environment. At the same time, it can reduce the impact of abrasive on the surface of copper parts and reduce the surface roughness. It is suitable for copper parts with high surface quality requirements.

It can be used for surface treatment of precision copper parts, such as electronic components and copper instrument parts, and can effectively remove tiny flaws and dirt without causing excessive damage to copper parts.

Four, automatic sandblasting machine

principle of operation

The movement of the spray gun and the sandblasting process are controlled by the automatic control system, which can realize the automatic sandblasting treatment of copper parts.

Features and applicable scenarios

High production efficiency, stable sandblasting effect and good consistency. It can greatly reduce manual operation and labor intensity.

Suitable for mass production of copper parts with regular shapes, such as copper fins and copper standard parts. Customized design can be carried out according to the specific shape and size of copper parts to ensure the uniformity and comprehensiveness of sandblasting effect.
