Prevention of Porosity in Silica Sol Precision Casting and Pouring Temperature

The development of silica sol precision casting in China has been relatively late. The product requires a relatively high precision process during the manufacturing process. Silica sol precision casting needs to further strengthen the product process in theory and practice. Correct understanding, and constantly supplement their basic professional knowledge.

Silica sol precision casting has enriched its practical experience. During the operation process, the entire precision casting production process will be straightened out to cast more powerful quality products. During the filling operation, the foam model needs to be decomposed by liquefaction. It will cause a lot of small molecule gas and foam ash.

These substances are harmful to people to a certain extent. In daily work, operators must strictly follow their operation manuals. Whether it is actual operation or auxiliary protection items, they must be carried out as required. During the operation process, you need to be proficient in the steps of the operation process.

Compared with some complex thin-walled castings, silica sol precision casting can reasonably and effectively improve the air permeability of the modeling shell of its precision castings during the operation process. When possible, vent holes can be set at the highest point. The pouring system is reasonably set up in this way to prevent pouring gas.

Silica sol precision casting should properly increase its pouring temperature during the operation process, reduce the distance between the ladle nozzle and the pouring cup as much as possible, and reduce the pouring speed reasonably and effectively, so that the molten metal can be filled smoothly.

The mold shell of silica sol precision casting must be fully baked, and the temperature must be high enough during the operation process, so as to ensure that the precision casting shell is fully baked, so that the product's gas-producing substances are fully eliminated, and the completely baked mold shell is white Or light gray, there should be no dark spots.

As a professional precision casting factory, with a professional technical team and reliable production capacity, Dongying Shengyu Metal Products Co., Ltd. warmly welcomes people from all walks of life to come to discuss cooperation.
