Comprehensive solutions for removing or removing paint from metal
Paint stripping. BRIO ultrasonic cleaning completely removes epoxy, polyester, water-based, polyurethane, and varnish paints. All of this is much faster and more efficient than traditional systems, without damaging or modifying the parts. It is also the best option for reconditioning parts for scrap, stripping frames, etc.
What does paint stripping involve?
Metal paint stripping is a process of removing layers of paint, rust, or other coatings from a metal surface. This procedure is performed to leave the metal clean and ready for a new coat of paint, welding, or other treatment. Depending on the type of metal and the paint to be removed, there are different stripping methods.
Stripping is crucial to ensure that the new layer of paint or coating adheres properly to the metal, improving the durability and appearance of the surface.
Specialists in aluminum and iron pickling
We are experts in industrialized processes for pickling iron and aluminum. We recover high-value parts such as alloy wheels or aluminum profiles in architecture, frames and other rejected parts.
Stripping of aluminum parts
Pickling aluminum parts presents some specific challenges due to the characteristics of the material and the nature of its surface. The main difficulties include:
Heat Sensitivity: Aluminum is a material that deforms easily at high temperatures. Thermal pickling or sandblasting methods can damage the aluminum surface or even alter its mechanical properties if temperatures or pressure are not properly controlled.
Aluminum’s reactivity with chemicals: Aluminum can react unpredictably with some chemicals, which can cause staining, corrosion, or the formation of an unwanted layer on the surface. Therefore, chemical strippers that are compatible with aluminum must be carefully chosen to avoid these problems.
Surface wear: Aluminum is a softer material than other metals such as steel, making it more susceptible to scratching and damage during mechanical stripping. The use of abrasive tools or sanding techniques must be done carefully to avoid damaging the surface.
Aluminum Oxide Film: Aluminum tends to form an oxide layer when exposed to air. This oxide is quite hard and tough, making the stripping process more difficult, especially if the layer is thick. Additionally, if not removed properly, it can interfere with the adhesion of the new layer of paint or coating.
Surface quality control: Aluminum pickling requires precise control to ensure that paint or contaminants are removed without affecting the metal’s surface quality. A poor pickling process can leave unwanted marks or textures that hinder subsequent treatment steps, such as painting or anodizing.
Therefore, it is important to select the appropriate stripping method for each situation, taking into account both the type of coating and the characteristics of the aluminum and the required precision.
Iron pickling
Pickling iron requires careful handling to avoid rust, damage, and other problems associated with the use of chemicals and abrasive tools.
Iron pickling presents challenges such as rapid oxidation of the metal after the process if not properly protected, the risk of damaging the surface with abrasive methods, the possibility of corrosion due to unneutralized chemical residues, and temperature control during thermal pickling to prevent deformation. Furthermore, it can be laborious and time-consuming, especially on large or complex parts, and requires caution when handling chemicals. Parts with irregular shapes or hard-to-reach areas also complicate the process.
