ISO 9001 precision stainless steel aluminium investment casting

With the development of mechanical and electrical product parts in the direction of thin-walled, complex, and lightweight, aluminum alloy precision casting technology has received great attention. The dimensional accuracy and surface quality of castings produced by investment precision casting are higher than other casting methods. Wide application prospects. However, it has many shortcomings such as many process parameters and mutual influence, long generation cycle, thin casting wall, and high scrap rate of complex curved surfaces.

Our method for stress cracking of stainless steel investment castings includes the following steps: Step 1: Open a new gate: Open a transition arc on both sides of the original gate to form a new gate; Step 2: Open gate stress Groove: Cut a section of arc groove near the stress concentration part of the new inner gate; Step 3: Group tree: When grouping the tree, the new inner gate is bonded to the center of the casting beam structure, and there is a transition arc on the side and the beam structure Connected, and the other side is bonded with the riser. Step 4: Shell making: The shell is made of silica sol paint when making the shell, and the number of shell layers is 78; Step 5: Pouring: Pouring in an intermediate frequency furnace during pouring. This method The contact cross-sectional area of ​​the new inner gate and the casting beam structure is unchanged, which can ensure the feeding of the casting beam structure. The bottom injection gating system scheme is adopted, and the reasonable casting parameters are used to ensure that the castings with no shrinkage cavity and porosity defects are obtained .
