The type of abrasive media used in a Vapormatt wet-blast system is determined by the effect or finish you want to achieve. Typically, for example, our customers use glass beads for a satin polished finished, or an aluminium oxide for matt. Dependent on the application, you can also use special abrasive media, such as ceramic, plastics and stainless steel shot.
One of the main strengths of wet blasting over other finishing processes is the degree of control it gives you. That control comes as a result of the many different elements you can adjust individually…
With many industries increasing the requirements for quality and process monitoring, wet blasting offers in-depth control to its users. With some of the largest numbers of available parameters among mechanical surface treatments, it becomes possible to measure and control almost every variable in the process. With Vapormatt wet blasting machines, users can create optimum conditions that are then maintained in order to improve the reliability of the process and increase the quality of the products being treated.
The ability to work with additives, such as degreasing agents or inhibitors, can improve the usefulness of wet blasting machines by combining process steps. The water eliminates the heat that can damage delicate surfaces, any static build up and the embedment of blast media in soft surfaces. It also increases the media flow over the work pieces, which improves the uniformity of the process to give more homogenous finishes. The improved finishes are critical in industries were consistency is key for the manufacturing process and downstream applications such as bonding or coating.
Wet blasting changes the surface profile and can, for example, produce a highly clean and reactive surface for coating. It can also remove burrs, machining notches, heat marks and heat scale. Other processes include the strengthening and hardening of surfaces by reducing tensile stresses and accurately honing cutting tool edges, allowing bandsaw blades to run at full speed from new and lengthening their life for example. Unlike dry-blasting, very fine abrasives can be used for those processes that require extra precision. All processes are carried out whilst simultaneously cleaning and degreasing.
Adding water to the process contains and controls the abrasive, meaning the workspace is cleaner and safer, lowering the time and money needed for cleaning due to a lack of dust. Unlike dry-blasting, certain applications can be done in-line, in a contained environment, helping to save space and improve productivity. The lack of dust also prevents re-contamination, a particular benefit for electrical components, and eliminates the risk of dust explosion.
With many industries increasing the requirements for quality and process monitoring, wet blasting offers in-depth control to its users. With the most controllable parameters for any mechanical surface treatment, it becomes possible to measure and control almost every variable in the process. With Vapormatt wet blasting machines, users can create optimum conditions that are then maintained, improving the reliability of the process and increasing the quality of the products being treated.
By adding water to the process, it gives users more control of the abrasive impact on the work pieces. Adjusting both water and air pressure can also reduce the abrasive media consumption, and by having the abrasive cushioned in water, it increases the life of critical wear items such as hoses and nozzles. And, because everything is controlled, you can automate and work in line. Lowering costs for replacement parts and increasing productivity.
All aspects of the process are environmentally friendly, making wet blasting an attractive alternative to many surface treatments. The use of water improves the operator environment by eliminating any dust or the need for large and expensive filtration systems. No harsh chemicals are required and the waste routes are easy to manage with inert materials used in the media and separation systems supplied to reduce the amount of waste from the process.
