Coatings at Douce-Hydro<\/strong><\/h2><\/div>
<\/div><\/div>

At Douce-Hydro, surface treatment is based on a rigorous process that is entirely controlled in-house, guaranteeing the quality, durability and optimum performance of metal parts, particularly hydraulic cylinders, the company’s specialty. This autonomy enables meticulous quality control at every stage, reinforcing Douce-Hydro’s commitment to excellence and customer satisfaction. <\/p>\n

The company’s expertise is based on innovative surface treatment techniques, developed by its R&D department since the 1990s. These include Keradouce\u00ae, a nickel- and chrome-free coating that protects cylinder rods against corrosion and abrasion, and Lasertek\u00ae, a welded coating process that improves cylinder resistance in extreme conditions. This know-how guarantees solutions tailored to the specific features of each hydraulic cylinder, meeting the requirements of the most demanding industrial applications.<\/p>\n<\/div><\/div><\/div>

Cleaning and preparation<\/h3><\/div>

The first step involves careful cleaning of the parts to remove any traces of oil, grease or dirt. This step is crucial to ensure the adhesion of the coatings. <\/p>\n<\/div><\/div><\/div>

Stripping<\/h3><\/div>

Pickling removes oxides and other impurities from certain metals. It is a preparatory operation, prior to treatment. <\/p>\n<\/div><\/div><\/div>

Heat treatment application<\/h3><\/div>

Some metal parts benefit from heat treatment to improve their strength and durability. This process involves heating the part to controlled temperatures in order to modify its physical properties. <\/p>\n<\/div><\/div><\/div>

Coating application<\/h3><\/div>

Depending on requirements, various coatings can be applied, such as paint, zinc plating or anodizing, to improve resistance to corrosion and weathering.<\/p>\n<\/div><\/div><\/div>

Hardness<\/h3><\/div>

Our internal rod finishing processes provide the hardness needed to guarantee cylinder life in the face of abrasion problems.<\/p>\n<\/div><\/div><\/div>

Each of these stages is subject to rigorous quality controls to guarantee compliance with the very strict standards applied by Douce-Hydro. Visual inspections and strength tests are an integral part of this procedure. <\/p>\n<\/div><\/div><\/div><\/div><\/div>

Prevent corrosion and abrasion<\/strong><\/h2><\/div>
<\/p>\n

Each metal part can be subjected to different conditions of use. This premise leads Douce-Hydro to create customized surface treatments based on the customer’s specific needs: this tailor-made approach guarantees protection adapted to each application. <\/p>\n<\/div><\/div><\/div>
