Three coordinate detectors, dimensional image measuring, instruments, metallographic analyzer, ultrasonic flaw detector. element analyzer and many other basic test machines. Which can fully confirm the quality we offered
2、indeendenly develop the process ofkey products, and constanly improve and enance the old process to achieve the best product performanc.For example, wechanged the producion process for barrel liner and iner from siniening to spray welding. Which increased the produc senvice lile 3-5 times then normal produclis
① The liner alloy layer :old sintering process
② Characteristics and advantages of the newspraywelding process: the product is better in dense, thehardness can reach more than 56 degrees, the servicelife of the product is 3-5 times that of the sinteringprocess, low cost, less waste.
