The die casting part is a kind of simple or complex metal part dies casting. It is to cast aluminum, copper, zinc alloy, copper alloy, aluminum alloy, and other metals heated to liquid by a die casting machine to produce aluminum, copper, zinc alloy, copper alloy, aluminum alloy, and other metal parts with limited shape and size.
Generally, these kinds of parts do not need finishing after casting, so the cost is saved to a certain extent. Therefore, these aluminum, copper, zinc alloy, copper alloy, aluminum alloy, and other metal die-casting parts are widely used in automobiles, electric vehicles, instruments, electronics, communication, toy, furniture, bathroom, and other industries.
However, some aluminum, copper, zinc alloy, copper alloy, aluminum alloy, and other metal die casting parts have waterproof or sealing purposes, so the sealing test of die casting parts is needed.
For die casting parts with waterproof or sealing requirements, the sealing test of die casting parts mainly focuses on the leakage ports with leakage such as cracks, pores, vortex holes, shrinkage holes, shrinkage porosity, slag holes, and pinholes. The sealing test of die casting parts can be used to quickly detect the products that meet the requirements and avoid the overall unqualified products caused by unqualified die casting parts.
The airtightness and waterproof detection of die casting parts generally adopt dry compressed air, and the air-gas molecules are relatively small. With the precision sensor of the airtightness and waterproof testing machine, small leakage can also be detected.
Of course, the volume and shape of different die casting parts are different, so different tooling fixtures need to be customized for fixation or hole plugging, so that the sealing and waterproof test of die casting parts can be carried out.
