CMIPC and JFMI Launch Riser Hammer

30/07/2015

China Machinery Industrial Products Co., Ltd. (hereafter referred as CMIPC) and JFMI earnestly implemented the plan for doubling export output and successfully developed the riser hammer, which is a state-of-the-art product and the first result achieved under the SINOMACH plan for doubling export output, filling up the gaps of China in this field. After one year of development and trial, the product has passed the test run and made its debut at Shanghai Casting Expo, attracting high attention from the sector.

The product is mainly designed to remove casting riser of large casting part. In the foundry industry, especially when it involves large casting, the removal of casting riser has been a headache for China's foundry plants. The traditional gas-cutting method not only oxidizes large quantities of materials, but also does harm to casting part, especially, Hadfield steel tends to destruct metallographic structure and cause cracks. The method of manual hammering only applies to small casting riser, and it has extremely low efficiency and requires high labor intensity. Powered by compressed air, the riser hammer has a special energy storage structure that is capable of releasing the stored compressed air quickly, in this way it obtains tremendous impact energy in only a moment, thereby removing casting riser of heavy casting efficiently and significantly reducing patch weld caused by inappropriate removal of riser and scrap. The wide application of the product will play a positive role in increasing the competitiveness of the casting products of China.
