Surface & Chemical Processing

.Ist das alles die gleiche seite?

Suppliers in this category provide surface treatment and chemical processing services, such as pickling, passivation, degreasing, and chemical surface preparation, that prepare or finish metal and other components before coating, assembly, or use. They serve manufacturers needing these processes as a service or in-house equipment.

    What Surface & Chemical Processing suppliers provide

    Suppliers in this category perform or supply equipment for surface treatment and chemical processing steps such as pickling, passivation, degreasing, phosphating, and other chemical surface preparation processes. These steps prepare metal and other components for coating, welding, assembly, or direct use by removing contaminants, scale, or oxide layers, or by forming a protective conversion layer. Core competence lies in matching the chemical process to the substrate and the following process step, such as ensuring a surface is correctly prepared for the coating system specified downstream. In the pre-selection phase, compare which substrates and process types each supplier handles, and whether they offer processing as a contract service or supply the chemicals and equipment for in-house use.

    Relevant standards

    Surface preparation before coating is commonly specified against ISO 8501, which defines visual cleanliness grades, while resulting coating systems are referenced against ISO 12944. Supplier quality management is typically certified to ISO 9001, and environmental management to ISO 14001.

    Frequently asked questions

    What is the purpose of chemical surface processing?
    Processes such as pickling, passivation, and degreasing remove contaminants, oxide layers, or scale from a surface, or form a protective conversion layer, preparing the component for coating, welding, or direct use.
