Coating the surface with powder is achieved by the use of a compressed electrostatic charge or air technique. When the powder is applied to the surface, it is heated until the powder will reach its melting point. The heating process will cause the powder to flow over the surface thus creating a uniform coating which is very resistant to damage. Protective coating systems have many benefits to offer to product end users.
Choosing the best coating provider
When looking for the best protective coating systems provider, you have to consider several factors. Ensure that the company utilizes the highest form or standard of modern coating technologies when coating hot steel work or cold steel work, tungsten carbides as well as high speed steel. Good companies coat their products with absolute uniformity ensuring the repeatability of the coating performance as well as its quality.
- Cutting. The use of hard coatings will reduce the crater wear and the abrasive wear on different tools for conventional dry, high speed and wet machining. With the use of sophisticated technology, smooth coatings are ensured which helps reduce the friction in between the tool and chip.
- Punching. Placing coating on products increase the life of the product because friction is reduced as well as material transfer on molds, dies and punches.
- Forming. In the different forming techniques like molding, coining, extrusion, deep-drawing and bending, the use of hard coatings will reduce the groove wear, friction as well as the built up edges. You need not repolish the functional surfaces in most cases.
- Injection molding. In the process of plastic forming, the homogeneous hard coating found on the mold cavity increases the productivity by ejection of the final form and lowering the degree wear. Protective coating will change the roughness as well as the surface structure of the molds. This process will alter the release property of the molds and will consequently shorten its cycle times. For those surfaces that are mirror-like, it is recommended that repolishing be done. Most coating methods are done “line-of sight” which follows that there are certain limitations when the coating is applied to deep slots and holes.
