Powder Coating
Surface treatment is performed in-house, from shot blasting to the final coat of paint. Much of what Lalmek Hydraulics manufactures is used in harsh environments, and in such cases, durability depends just as much on the pretreatment as on the paint itself.
Shot blasting as a pretreatment
We blast the components with steel shot propelled at high speed. The result is a clean, slightly rough surface that provides the best possible adhesion for the powder coating—it is the pretreatment that determines how long the surface will last. The method is also environmentally friendly, since the steel shot is reused and no chemicals are needed. We can blast components up to 5,500 × 1,200 × 350 mm.
Coating and Curing
After blasting, the component is coated with electrostatic powder paint, which is cured at high temperature in a curing oven. This provides excellent corrosion protection and a uniform finish, and—compared to many other surface treatment methods—offers advantages in terms of cost-effectiveness, durability, and environmental impact.
