Jinan Linqing Foundry Technique Co., Ltd is a high-tech company consisted of senior technical staff with rich experience who come from the production line, scientific research and institutions of higher education. Over the years, our company devotes ourselves to the research and development, and the application and popularization of the complete set of core making equipments. Currently we have obtained 8 national invention patents and applied on our products such as sand mixer, core shooting machine, gas generator and sand handing similar The Linqing series robot core making center developed and researched by our company has been successfully adopted in the DI pipe industry of China and oversea market. It achieves clean production with the advantage of saving workforce. The workmanship yield rate of raw materials almost reaches 100%. The specific character of this system is it has fundamentally achieved the high precision control to the whole core making process. It is stated from:

The temperature of the raw material, the proportioning, the dosing amount at every turn, the time of shooting sand and air exhausting, the air blowing pressure, amine gassing amount and gasification temperature, the mold opening and core taking, coating paint and the sand core storage. All of this process is controlled by the PLC.

This system eliminates a series of uncontrollable problems existing in the whole core making process currently, which achieves the operation based on the best technical process. The actual productivity is 3-4 times of the currently adopted equipments. At the same time, it can save 90% of the workforce, reduce 98% of waste exhaust and 50% of gas exhaust, decrease 50% of energy consumption, and save 10% of resin consumption and 50% of amine consumption. Therefore, it fundamentally achieves the modern civilisation production which has the characteristics of high productivity, energy saving, low consumption and low exhaust.
