Introduction to Control Methods for Wax Mold Size in Precision Casting

Precision casting is a casting technology with high precision and quality requirements, suitable for producing various precision parts, such as components in aviation, aerospace, automotive, medical and other fields. The wax mold casting technology is a commonly used wax mold precision casting process, which uses melted wax molds to make castings in molds. The control of wax mold size in precision casting is an important link to ensure casting accuracy.

1、 Preparation of wax molds

The preparation of wax molds is an important step in precision casting. When preparing wax molds, it is necessary to accurately control the size of the wax molds to meet the accuracy requirements of the castings. When preparing wax molds, it is necessary to control the shrinkage rate of the wax mold to avoid excessive size deviation between the wax mold and the casting, which affects the accuracy of the casting.

2、 Mould manufacturing

The manufacturing of molds is another important aspect that affects the size of wax molds. When manufacturing molds, it is necessary to strictly control the dimensional accuracy of the molds to ensure the consistency of wax mold dimensions. When manufacturing molds, high-precision processing equipment and processes are required to ensure the dimensional accuracy of the molds.

3、 Wax mold injection molding

Wax mold injection molding is the final step and a very important step in the preparation of wax molds. In wax mold injection molding, it is necessary to control parameters such as temperature, pressure, and speed to ensure dimensional consistency of the wax mold. During wax mold injection molding, it is necessary to control parameters such as pressure, temperature, plasticization time, and injection speed to ensure that the dimensions prepared by the wax mold meet the design requirements.

4、 Wax mold immersion coating

Wax mold immersion coating is the final step before preparing castings and also a key link to ensure casting accuracy. When applying wax molds, it is necessary to control the concentration, temperature, immersion time and other parameters of the coating to ensure the uniformity and appearance quality of the coating.

In summary, the key to controlling the size of wax molds in precision casting is to control the parameters of all links, in order to ensure that the size of wax molds can meet the design requirements. At the same time, it is necessary to strictly follow the manufacturing process specifications, strengthen on-site management, ensure the quality of each process, and thereby improve the production efficiency and quality level of the entire precision casting.
