Phosphate coating and degreasing

Phosphate coating (otherwise also Parkerising or Bonderising) is a chemical surface treatment of a metal component. Together with degreasing, it serves to improve the adhesion for the next coating.

What is phosphate coating and degreasing?

An insoluble, electrically non-conductive layer with a thickness of approx. 2 µm is formed on the steel product during phosphate coating. It protects products against corrosion and improves paint adhesion. Phosphate coating reduces friction during cold forming of steel parts. We usually use iron and zinc phosphate for phosphate coating. Phosphate coating and degreasing takes place at a temperature of approximately 60 °C.


We provide pre-treatment of parts on the MCL 800/OS carousel degreasing machine from SUMMA Šumperk. Its main advantage is degreasing, phosphate coating and subsequent rinsing and drying in one technological cycle. We degrease products after machining, before painting, surface treatment and heat treatment in a chamber automatic vacuum device from EMO, type VAIOCS1, equipped with a Siemens control system.

Why phosphate coating and degreasing?

Phosphate coating is a particularly important pre-treatment for a product surface. We cannot be without it, not only when painting.

Thanks to phosphate coating:

  • friction is reduced during forming
  • paint adhesion and lubricant is increased
  • corrosion protection and electrical insulation are created

Our services

Technical preparation of production

Technical preparation of production (TPP) means detailed technological procedures and activities preceding the production of the ordered component.

Metal cutting

Cutting means machining of a metal workpiece using a machine tool. Metal chips are formed during cutting.

Chipless technologies

Chipless machining methods do not use material removal by mechanical work. Unlike cutting, they produce virtually no chips.


Painting is the final stage of metal surface treatment. In our modern paint shop, we provide powder and wet coating on delivered components.

Electrical equipment production and assembly

We do not focus exclusively on metalworking. We also offer these services for our customers so that they have no need to go elsewhere in terms of electrical equipment production and assembly.

Cutting tools and assembly jigs production

We can produce special cutting tools for sheet metal processing on hydraulic or manual presses. All we need is drawings.
