Cast iron weights, 25 kilograms of cast iron weights, 20 kilograms of cast iron weights-how does the production defect come about
The management of casting sand for cast iron weights is very important. Cast iron weight castings are all made of sand. Many factories do not strictly manage the sand. Often the sand has poor air permeability and poor air permeability, resulting in cast iron weight castings. Prone to pores. In addition, the low strength of the molding sand causes the mold to break. Poor quality of cast iron weights is mostly caused by poor casting sand. Due to the limitation of the level of knowledge and production conditions in the production of cast iron weights, it is entirely possible for castings to have one or another defect. Whether the quality of the casting meets the requirements specified in the technical conditions can only be assessed through inspection. Cast iron inspection platform casting quality inspection is an operating process to inspect whether cast iron weights are qualified by visual inspection, measuring tools, meters or other means according to user requirements and drawing technical conditions and other relevant agreements. The quality inspection of castings is not only to find defects, but to further find out the reasons for the defects based on the judgment of the defects, and to formulate measures to prevent them. This prevents similar situations from appearing when the cast iron inspection platform castings are produced in the future, so as to meet user requirements. Qualified cast iron testing platform products should include three aspects: appearance quality, internal quality and use quality.
