The main production process of aluminum die casting
Nov 20, 2024
The main production process of aluminum die casting includes the following steps:
Mold design: First, design the mold according to the product requirements. The mold design should ensure that the shape and size of the casting meet the industrial standards, and the design should be complete and the structure should be simple to ensure the accuracy of the casting.
Mold making: After the mold design is completed, mold making is carried out according to the design drawing. The mold making process requires strict process requirements to ensure the accuracy and stability of the mold.
Equip the mold and adjust the parameters: Install the prepared mold on the specific casting equipment, and adjust the parameters of the equipment to ensure the accuracy of the aluminum alloy parts during the casting process.
Aluminum alloy material preparation: Prepare aluminum alloy materials that meet the requirements, commonly used are ADC12, A380, etc.
Aluminum liquid injection: Pre-melt the aluminum alloy material and inject it into the mold. Before injection, precise measurement and temperature control and other steps are required to ensure the casting quality.
Mold cooling: The aluminum liquid in the mold is quickly cooled and formed in a short time. The cooling time and temperature are important factors affecting the quality of the workpiece.
Demolding of aluminum alloy parts: After the mold is cooled, the mold is opened and the die-cast aluminum alloy parts are taken out of the mold.
Surface treatment: After the aluminum alloy parts are taken out, a series of surface treatments such as trimming, finishing, painting or spraying are required to meet the appearance and surface quality requirements of the parts.
Inspection: The aluminum alloy die castings are inspected, including dimensional accuracy, appearance quality and defects, etc. After the inspection, it can be determined whether the aluminum alloy die castings are qualified.
The advantages of aluminum die casting include:
High precision of parts: During the aluminum alloy die casting process, the mold can be swung in an open and mobile manner, so that the aluminum alloy liquid is evenly distributed in the mold, reducing the percentage shrinkage of the casting, thereby obtaining high-precision aluminum alloy parts.
High production efficiency: Aluminum alloy die casting can use multi-cavity molds, which can cast multiple aluminum alloy parts at a time, improve production efficiency, and reduce material waste.
Good surface quality: Aluminum alloy die casting can obtain high-quality surfaces without post-processing. High material utilization rate: Aluminum alloy die-casting process can efficiently utilize materials and reduce waste.
