manual cold chamber die casting working process

Описание: The manual cold chamber die casting process usually produces die casting parts with insert parts or casting parts with special structures. In the manual casting operation process, some processes can reach automatic working, such as pouring molten metal into the cold chamber, lubricating the mold, etc. Worker sets insert parts to mold cavities and manually pick up the die casting parts from mold processes.
It involves the following manual working steps:
1. Die Preparation:
The die, which is a metal mold, is prepared for the casting process. This includes cleaning and lubricating the die to ensure smooth operation.
Injection of Molten Metal:
In the cold chamber die casting process, the molten metal, often aluminum or other alloys with higher melting points, is kept in a separate furnace. The metal is ladled into a shot chamber and then manually or automatically injected into the cold die.
2. Solidification:
The injected molten metal rapidly cools and solidifies within the die cavity, taking the shape of the mold. This process requires careful monitoring to ensure the desired quality and structure of the final product.
3. Ejection of the Casting:
Once the metal has solidified, the die is opened, and the casting is ejected manually or using an ejection mechanism. This step requires precision to avoid damaging the casting or the die.
4. Trimming and Finishing:
The castings may undergo additional manual processes such as trimming, removing excess material, and finishing to achieve the final desired shape and surface quality.
5. Quality Inspection:
Each casting is inspected manually to check for any defects, such as porosity, surface irregularities, or dimensional inaccuracies. Quality control is crucial in ensuring the integrity of the final product.
6. Reassembly of the Die:
The die is cleaned, and its components are reassembled for the next casting cycle. This step may involve some manual adjustments and maintenance to ensure the die's longevity and performance.
Throughout these steps, skilled workers play a vital role in the cold chamber die casting process to achieve high-quality and precise metal castings.
