Silicon sol precision casting itself has a small size and does not require high precision, so tin bismuth aluminum frames can be considered as molds. The weight of tin bismuth molds is relatively heavy because they contain bismuth, but for producing complex molds, the production time is short, saving machine costs.

Silica sol precision casting is suitable for casting various types and alloys. When using this technology to produce castings, the dimensional accuracy and surface quality are higher than other casting methods. Casting methods are difficult to cast complex, difficult to handle, and heat-resistant castings. If we want to produce products with simple shapes and small sizes, we can choose profiles or use cast steel to process products with high dimensional accuracy.

We need friends who use silica sol precision casting processing, mainly for the above applications. We should pay more attention to the processing of these applications.

Welding operations that cannot be carried out on stainless steel precision aluminum castings

There are many industrial occasions that require stainless steel precision aluminum castings, but some products do not meet the requirements, so welding operations are not allowed. If operated consistently, it will only lead to quality problems. In order to avoid serious problems, it is necessary to fully understand the situation where stainless steel precision aluminum castings cannot be welded, so as to select processing techniques with targeted measures.

Users have high precision requirements for stainless steel precision aluminum castings, and welding cannot be carried out without meeting the requirements. For example, some places are clearly specified in the drawings and cannot be welded. There is another situation, which is that stainless steel precision aluminum castings themselves have quality problems that cannot be welded, including leakage during casting pressure testing; There are porous pores on the surface, which cannot guarantee the quality of the castings after welding.

In addition, if a certain position has already been welded, welding cannot be carried out anymore, which will affect the quality of stainless steel precision aluminum castings and even affect their effectiveness. Remember these requirements and handle them carefully.
