A wide range of surface processes are used in manufacturing to improve part surfaces. They can add material layers to a surface, remove undesired materials from a surface, reshape a surface, or modify the properties of a surface. In this article, we’ll go over different types of surface processes and technologies to learn which one is good for what application.
Many manufacturers have trouble grasping the difference between laser cleaning and plasma cleaning. After all, both are non-contact processes that do not require solvents or chemicals like chemical cleaning, and they are sought after to replace abrasive techniques like sandblasting and dry ice blasting.
Nowadays, parts and products are often subjected to harsh conditions that result in wear, erosion, abrasion, and corrosion. To prevent this from happening, they need protective coatings. While many coating deposition methods exist, thermal spray coating is one of the most popular, chosen for its speed and versatility.
Laser cleaning systems are making their way as great alternatives to traditional surface cleaning methods likes chemical cleaning and abrasive blasting. Manufacturers who need clean metal surfaces are increasingly looking at laser cleaning as an environmentally friendly, cost-effective solution that provides more consistent results.
Masking tapes have long been used to prevent specific areas from being spray coated or grit blasted. But did you know that lasers provide a faster and more reliable alternative that’s easier to automate?
There are now countless ways to blast a surface due to the variety of abrasive materials. But abrasive blasting systems come with important downsides. Most manufacturers are used to manage these downsides, but others are turning to alternatives like laser texturing—especially when precision is needed or when processing a large number of parts.
Whether you’re looking to remove phosphate coating, e-coating, powder coating, or epoxy, there is not a single method that works best for all applications. Laser cleaning, chemical stripping, abrasive blasting, burn-off ovens, induction heating, and other methods all come with different benefits and limitations.
The most common methods for e-coating removal include burn-off ovens, sandblasting, and chemical stripping. A more modern technology is laser cleaning. It is adopted by manufacturers who need speed and precision, as well as those who want to get rid of consumables.
Laser dust removal is the process of removing dust from a surface using laser ablation. Any types of dusts produced in work environments can be removed, such as metallic, plastic and organic dust. As the laser beam irradiates the surface, burnt off dust is vaporized and extracted using a dust extraction nozzle
