Aluminum die casting is a high-pressure metal forming process used to create complex, near-net-shaped parts from molten aluminum alloy. The process injects aluminum alloy under extreme pressure into a custom steel mold located inside an automated machine. The aluminum die casting process provides a cost-effective, efficient way to produce durable, precision parts that meet the demanding requirements of today's high-performance, high-temperature, and corrosion-prone environments.

Aluminum die casting stands out for its ability to efficiently produce highly complex shapes with tight tolerances that other processes like extrusion and machining struggle to achieve. This makes it ideal for manufacturing intricate components such as automotive transmissions and engine blocks. Additionally, it offers the flexibility to create parts with either textured or smooth surfaces and is capable of handling a wide range of part sizes, from very small to large components.
Our aluminum die casting standards ensure exceptional quality through the use of high-purity aluminum alloys, precise dimensional accuracy, and smooth, defect-free surfaces. Each casting is designed to meet strict mechanical property requirements, including strength, hardness, and elongation, verified through rigorous testing and quality control. The die casting process is meticulously controlled, from melt temperature to cooling rate, while comprehensive inspections using X-ray, ultrasonic, and visual techniques guarantee compliance with the highest quality standards.

Aluminum die casting is a manufacturing process that utilizes reusable steel molds (dies) to create geometrically complex metal parts. Molten aluminum alloy, prepared in a furnace, is injected under high pressure into the dies. This rapid injection ensures the metal fills intricate details. The aluminum then rapidly cools and solidifies within the mold, taking its precise shape. The resulting parts are near-net-shaped, potentially requiring minimal post-processing steps.

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 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 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 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
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 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 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 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, 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.)
