Inovatec Machinery“The ultimate water blasting machine manufacturer at your disposal. ”

The concept of water blasting or hydro blasting is not very old in the mass finishing industry. It’s one of a kind blasting equipment that uses the power of water to clean and deburr the surface of the product. It’s a revolutionary new method that changed the world of mass finishing for good.

A water blasting machine is commonly used to clean aerospace parts, weapons, automobiles, optics, electronics, and virtually any other industrial parts. Even industries that require high precision such as the watch industry, jewelry industry, etc. can also benefit from a hydro blasting machine.

A wet blasting machine utilizes the power of compressed air to force the water out at a very high speed to clean and deburr parts. Inside the spray gun, the water gets accelerated with help from compressed air and shoots out through a nozzle.

A water blasting machine simply uses water to operate. There is a pump inside the machine that generates the power to accelerate the water. The water then comes out at a greater force which in return cleans the surface of the parts, also known as hydro cleaning.

16. What is the application of the wet blasting process?

16.1  Clean the rough surface of precision castings

Wet blasting is used to clean the scale and residual on the surface of precision castings, especially for the cleaning and polishing of precision parts. It is the most economical and effective process for such operations.

At the same time, it can play a polishing role and improve the surface finish of castings. For example aero-engine turbine blades, surgical instruments, jewelry, etc. The use of water blasting to clean the die-casting parts can expose the parts to the same metallic color and make them more beautiful.

If the liquid shot peening effect is better, the surface hardness and corrosion resistance of the parts such as various instrument shells, frames, jewelry, etc. can also be improved. For sand casting aluminum, copper, and other metals, the use of liquid blasting can also achieve a higher surface quality thus saving many intermediate process links.

16.2 Remove oxide scale

The oxide scale and residual salt after heat treatment can be removed by wet blasting machine. This process can also improve the surface finish of many parts, especially like the complicated shapes of molds and liquid blasting of precision parts.

For example, the liquid blasting off the file after heat treatment will not only damage its edge but also increase its service life.

16.3 Removal of micro burrs on machined workpieces

Although burrs are usually small, they can be very harmful. Even a little burr is not allowed in cases like textile machinery parts, hydraulic components, and the precise aerospace industry. Besides, medical instruments, parts, castings on dental restorations, etc., use hydro blasting to remove burrs.

Both the efficiency and quality are of high grades here. It can make the corners of two surfaces appear as small rounded corners (this is required by many mechanical parts).

16.4 Clean up dirt and rust

Various molds such as forging molds, stamping molds, rubber molds, tire molds, plastic compression molds, glass product molds, etc. will be contaminated with mold release agents and other dirt or burn marks after using for a certain period.

At the same time, it can decrease the mold’s service life.

The use of liquid wet blasting on food molds can meet their medical sterilization requirements and improve the pressure resistance of ceramic components in the electronics industry

This technology of refurbishing old mechanical parts and automotive spare parts can make them look as good as new.

16.5 Prepare for other surface treatment processes

The liquid wet blasting pretreatment is used before plating the parts.

The plating layer has a strong binding force, especially for hard chrome plating like engine piston ring, textile machine wire roller plated pear surface chrome, etc.

For paint parts and sprayed parts, the use of liquid hydro blasting before spraying can enhance the bonding force of the coating

The use of wet blasting for bonding parts has good quality and higher strength.

16.6 Improve the performance of mechanical parts

After the mechanical parts are blasted with a liquid, the sprayed surface has microscopic uniform pits in addition to improving the 0.5-1 level finish on the original basis. These pits can maintain the storage of lubricating oil and improve the lubrication conditions, thus extending the parts.

Increase the service life while reducing the noise of mechanical operation for gears, crankshafts, textile machinery, sewing machinery, etc.

After mechanical parts are blasted with a liquid, especially after liquid shot blasting, the fatigue strength and corrosion resistance of the parts can be significantly improved. For instance: springs, turbine blades, etc.

After the liquid blasting of mechanical parts and castings, small surface defects are easily exposed, which is helpful for the inspection and detection of cracks.
