Overview
A crystalline carrier layer on the metal before forming
KİMSOL zinc phosphate baths form a porous, crystalline conversion layer on the metal surface. This layer holds the drawing soap (Kimkal) and prevents metal-to-die contact during drawing and cold forming, reducing friction and wear.
Consistent coating weight
Uniform, repeatable forming through controlled g/m².
Long die life
Cuts metal-to-die contact and reduces die wear.
Excellent soap pickup
The porous structure keeps the drawing soap on the surface.

Benefits
Measurable process gains
Longer die life
Cutting metal-to-die contact reduces wear and lowers the frequency of die changes.
Lower chemical consumption
A stable bath and the right coating weight mean less consumption per unit.
Consistent coating and surface
Batch-to-batch repeatable quality; uniform forming and low scrap.
Line efficiency
Fewer stoppages and less rework; safe operation at high drawing speeds.
Frequently Asked Questions
Common questions
What does zinc phosphate coating do?
Zinc phosphate coating forms a porous, crystalline conversion layer on the metal surface. This layer holds the drawing soap and creates the carrier surface it needs; by preventing metal-to-die contact during drawing and cold forming, it reduces friction, wear and die-life loss.
What coating weight should KİMSOL give?
The typical range for zinc phosphate coatings is 3–15 g/m². The right value depends on the material, the reduction ratio and the next forming step: heavy deformation calls for the upper band, while light drawing and jobs where surface appearance is critical use the lower band.
Which metals is it used on?
KİMSOL zinc phosphate coating is suitable for carbon steel and low-alloy steel. The surface must be free of scale, rust and oil, which is why degreasing and rinsing steps are essential before phosphating.
Is KİMSOL zinc phosphate or manganese phosphate?
The KİMSOL series is zinc phosphate based. It is the type used in wire/tube drawing, cold forging and paint pretreatment, with a crystal structure suited to soap pickup and forming. Zinc phosphate is the preferred type for cold forming lines.
