ISO 9001 AND 14001 CERTIFICATES
We rigorously comply with all quality and environmental standards. The company´s management policy is at your disposal.
WE HAVE SPECIAL 8m x 0,50m x 1,30m TANKS FOR ALL TYPES OF METAL PARTS
DEGREASE
Degreasing treatment is necessary to remove oil and grease residues from previous manufacturing processes. Good degreasing avoids the carry-over of oils and greases to subsequent treatment stages. We use chemical, cathodic and electrolytic-anodic types of degreasing.
PICKLING
Pickling is the process that removes any impurities or surface finishes that the part may have, such as stains, rust or other impurities, in order to activate the surface of the parts for subsequent zinc plating.
ZINC ACID
Acid zinc baths are used in markets where corrosion protection requirements are not so high and a high level of brightness is a priority. Furthermore, these baths allow the zinc plating of materials that are difficult to treat, such as cast iron, malleable iron and carbonitrided iron.
ZINC NICKEL ACID
The highly efficient Acid Zinc Nickel coating has exceptional corrosion protection and is highly resistant to high temperatures. It has corrosion resistance equal or superior to that of acid zinc, increasing hardness and wear resistance.
TYPES OF PASSIVATION
We offer the following treatments to add colour to the pieces and protect them against oxidation.
BLACK PASSIVATED
We offer information on how to achieve the desired results when coating zinc-nickel parts with a black passivate.
BLACK PASSIVATED
We offer information on how to achieve the desired results when coating zinc-nickel parts with a black passivate.
TRANSPARENT PASSIVATED
A transparent passivate that operates under mild conditions, it allows for minimal alloy loss during passivation.
IRIDESCENT TRIVALENT PASSIVATED
Passivate with a reddish-blue iridescent layer.
SEALING
Final treatment with special seals to extend the anti-corrosion time and complete the passivation process.
