We enhance the quality of surfaces by removing water-soluble oils, shielding them against corrosion, and preparing your parts for downstream coating processes.
Advanced cleaning for contaminant-free surfaces
- Independent 5-stage line for the chemical preparation of metal surfaces.
- Selective activation of stages according to project requirements.
- Iron phosphate application as a conversion base to improve adhesion.
- Integration of a corrosion inhibitor for temporary protection prior to coating.
Our processes protect metal parts against corrosion
The line operates as an automated conveyor tunnel and integrates the following stages:
- Alkaline degreasing to remove water-soluble oils and light residues.
- Intermediate rinse.
- Iron phosphating to generate a conversion layer.
- Final rinse.
- Corrosion inhibitor application when required by the project.
The system is designed to prepare metal surfaces before coating or as a standalone service when the client only requires cleaning and phosphating.
Heavy or non-soluble contaminants must be removed beforehand using external methods, subject to technical evaluation.
A dedicated line for cleaning and pretreatment
The degreasing and phosphating line operates through a 5-stage system designed for the chemical preparation of metal surfaces.
The process integrates alkaline degreasing to remove water-soluble oils, intermediate rinses, iron phosphate application as a conversion layer, and — when the project requires it — a corrosion inhibitor for temporary protection before coating.
Continuous conveyor-belt process with spray pretreatment and drying oven
Depending on the part’s downstream use, the following process combinations can be selected:
- Degreasing and drying the part.
- Degreasing, phosphating, and drying of the part (for parts undergoing a downstream coating process within a short window — maximum 2 days).
- Degreasing, phosphating, application of a corrosion inhibitor, and drying of the part (when the part will remain in storage for several days before being coated).
- Degreasing, application of a corrosion inhibitor, and drying of the part (when the part must be clean for a downstream manufacturing process and corrosion protection is required).
The corrosion inhibitor provides temporary protection during indoor storage, lasting up to 30 days under controlled storage conditions.
Maximum part dimensions:
- Length: 1.00 m
- Width: 1.20 m
- Height: 0.30 m
- Maximum weight of 40 kg per part.

Frequently Asked Questions
Service is a fundamental part of our work. Please don’t hesitate to contact us with any questions about our solutions.
-
What type of phosphating do you use on this line?
This line operates with iron phosphate when required, helping to improve adhesion of the final coating.
-
What process controls do you implement to ensure pretreatment quality?
We monitor critical parameters such as chemical concentration, pH, temperature, and exposure times, through documented controls and periodic records that ensure treatment stability.
-
Can degreasing and phosphating be offered as a standalone service?
Yes. The process can operate as an independent service when the client requires parts that are clean and prepared for their own coating system.
-
What types of contaminants does the process remove?
The system is designed to remove water-soluble oils and light residues compatible with alkaline treatment. Heavy or incompatible contaminants must be removed beforehand using external methods.
-
Is it compatible with different substrate types?
The process is designed for metal components compatible with iron phosphate. Feasibility is validated based on the substrate type and surface condition of each project.
