Casting machine quality appraisal

casting machine is a professional equipment used to melt metal materials and pour them into molds to create the required products. Casting machines usually consist of multiple parts such as furnaces, molds, pouring systems, molds and processing devices.
Through the action of a casting machine, metal can be formed into the desired product in precise shapes and sizes. Casting machines can produce many different types of parts and products, covering many fields such as automotive and mechanical parts, construction and metallurgical materials, industrial and daily necessities.
In casting machine quality appraisal cases, Zhongke Testing can provide casting machine quality appraisal services.

According to the direction of the rotation axis of the mold, centrifugal casting machines are divided into three types: horizontal, vertical and inclined.
horizontal centrifugal casting machine is mainly used for pouring various tubular castings, such as gray cast iron ductile iron water pipes and gas pipes, with a minimum pipe diameter of 75 mm and a maximum of 3000 mm. In addition, it can cast large-diameter copper rollers for paper machines, various carbon steel, alloy steel pipes, and double-layer steel rollers that require different compositions in the inner and outer layers.
vertical centrifugal casting machine is mainly used to produce various ring castings and smaller non-circular castings.
metal mold gravity casting machines are divided into two categories, namely tilting gravity casting machines and fixed gravity casting machines. The tilting gravity casting machine can realize tilting casting of molds, which can effectively improve the inherent quality of castings. It is especially suitable for gravity casting of complex castings such as intake manifolds.

A dispute arose between a metal materials company and a metallurgical construction company over whether the iron casting machine equipment met quality standards, so they appealed to the court.
Our company was entrusted by the court to undertake the quality analysis of the "cast iron machine" involved in this case.
appraisal analysis results: The
quality analysis expert group discussed and comprehensively technical analyzed the relevant information, on-site investigation and inspection, and inspection and testing data of the "cast iron machine" involved in the case, and made the following quality analysis opinions:
The longitudinal centerline of the active and driven sprocket shafts of the "cast iron machine" involved in the case is deviated by 123mm, which does not meet the requirements of relevant standards.
