Selection of blasting equipment

1. Generally speaking, the blasting effect is mainly determined by the parts material and blasting abrasive. Depending on the material of the part, blasting materials can range from strong metal abrasives to soft resin abrasives, with dry blasting and liquid blasting also being important considerations.

2. The production efficiency determines the type of equipment:

According to the processing capacity, choose automatic sandblasting production line, semi-automatic sandblasting equipment, press-in sandblasting machine, and suction sandblasting machine.

3. The size of the workpiece determines the equipment specifications:

The size of the nacelle is selected according to the size of the workpiece, so that there is enough space for the processing work.

4. Compressed air requirements:

Determine the capacity of the air compressor according to the equipment specifications, and leave a 20% margin to protect the service life of the air compressor.

1. Function or purpose

1. Workpiece surface cleaning

It can be used as rust layer on metal, residual salt and oxide layer on the surface of heat-treated parts, oxide layer on the surface of rolling parts, oxide layer on the surface of forging parts, oxide layer on the surface of welding parts, molding sand and oxide layer on the surface of casting parts, The residual dirt and tiny burrs on the surface of the machined parts, the surface of the old parts, etc. are treated to remove the surface adhesion layer and reveal the true color of the substrate. The surface cleaning quality can reach Sa3 level.

2. Pretreatment of workpiece surface before coating

Can be used as a pre-treatment process for various electroplating, brushing, spraying and bonding processes to obtain active surfaces and improve adhesion between plating, coatings and bonding.

3. Change the physical and mechanical properties of the workpiece

It can change the surface stress state of the workpiece, improve the lubrication conditions of the mating parts, and reduce the noise during the movement of the coupling parts. Harden the surface of the workpiece and improve the wear resistance and fatigue strength of the parts.

4. Finishing of workpiece surface

The Ra value of the surface roughness of the workpiece can be changed. It can produce matt or diffusely reflective workpiece surface to achieve the purpose of finishing.

Second, the main parameters

Main parameters affecting sandblasting: abrasive type, abrasive particle size, abrasive liquid concentration, spray distance, spray angle, spray time, compressed air pressure, etc.

Three, environmental protection features

1. It greatly improves the pollution of dust to the environment and the harm to workers' health.

2. It can be directly installed on the production line, saving production area and facilitating workpiece turnover.

3. The working method is flexible, the process parameters are variable, and it can adapt to the finishing processing requirements of different materials and parts with different precision.

4. The abrasive is recycled during the working process, and the consumption is less
