Cold Chamber Die Casting Surface Finishes

The ultimate stage in precision die casting is post-processing and finishing, which involves applying various techniques to eliminate surface defects, enhance mechanical or chemical properties, and improve the cosmetic appearance of cast parts. We offer you a variety of high-quality finish options to match your final product. All our finishes are ROHS and REACH compliant.

Polishing

Polishing

Polishing

Polishing refers to the processing method that uses mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification and processing of the workpiece surface using polishing tools and abrasive particles or other polishing media.

Electroplating

Electroplating

Electroplating

Electroplating is the process of depositing metal or alloy on the surface of the workpiece by electrolysis to form a uniform, dense and well-bonded metal layer, which is called electroplating. Simple understanding is the change or combination of physical and chemical.

Baking paint

Baking paint

Baking paint

Baking paint is a spray paint production process. The method is to polish the die casting parts to a certain degree of roughness and spray several layers of paint on the substrate, and then bake and set at high temperature. At present, this process has higher requirements for paint and better color rendering. It is mainly divided into two categories: low-temperature baking paint and high-temperature baking paint. The temperature of low-temperature baking paint is between 140°C and 180°C, and the temperature of high-temperature baking paint is between 280°C and 400°C. Depending on the paint, whether to perform low-temperature paint or low-temperature paint is selected. High temperature paint.

Powder coating

Powder coating

Powder coating

The powder coating is sprayed onto the surface of the die casting with a powder spraying equipment. Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the die casting to form a powder coating. After high temperature baking and leveling curing, the powder coating becomes the final coating of different types of powder coatings; the texture can be adjusted to various effects, such as smooth surface, sand texture, foaming, etc.

Passivation

Passivation

Passivation

Passivation is a process in which a metal is treated in a nitrite, nitrate, chromate or dichromate solution to form a chromate passivation film on the metal surface. It is often used as a post-treatment for zinc and cadmium coatings to improve the corrosion resistance of the coating; the protection of non-ferrous metals; and the adhesion of the paint film, etc.

Sandblasting

Sandblasting

Sandblasting

Sandblasting is to use compressed air as the power to form a high-speed jet beam, and spray abrasives (steel grit, brown corundum, glass beads, emery, etc.) at high speed to the surface of the die casting to be treated, so that the appearance of the outer surface of the die casting changes. Due to the impact and cutting effect of the sand on the surface of the die casting, the surface of the die casting can obtain a certain cleanliness and different roughness, so that the mechanical properties of the surface of the die casting can be improved, thus improving the fatigue of the die casting. It increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also beneficial to the flow and decoration of the coating.

Anodizing

Anodizing

Anodizing

Anodizing is a surface treatment process that uses electrochemistry to form a layer of Al2O3 (aluminum oxide) film on the surface of aluminum and aluminum alloy. Through anodic oxidation, the surface state and performance of the material can be changed, thus improving corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface.

Cataphoresis

Cataphoresis

Cataphoresis

Cataphoresis, also called electrophoresis deposition(cationic electrophoresis), is a surface treatment that consists of electrochemically depositing an epoxy-type coating on a metal part (steel, cast iron, aluminium, magnesium, etc.)
