We manufacture screw and kneading segments for co-rotating twin screw extruders ranging from 20 mm to 200 mm and over. Our manufacturing specializes in segmented screws for twin screw extruders and is optimized for flexible order handling.
After several years of researching, we developed the new material BLM6 (Cobalt Alloy 6). It has a hardness of HRC40-45 and possesses the same corrosion resistance as HC276 materials, whereas HC276 only has a hardness of HRC22-26.
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.
"In twin-screw extrusion, screw elements are not just consumable parts—they are the heart of your production line's profitability. Over my 26 years in the metallurgy and extrusion industry, I've seen factories lose millions due to frequent downtime caused by incorrect material selection. That’s why we developed BLM6 (Cobalt Alloy 6). By upgrading from traditional sintering to our advanced spray welding process, we help our global partners extend the lifespan of their wear parts by 3 to 5 times. We don't just supply parts; we engineer reliability."

Our customized conveying, kneading, and mixing elements are engineered to handle the most demanding materials across various industrial sectors:
A: Yes. We utilize high-precision 3D scanning and CNC machining to manufacture 100% compatible replacement parts for almost all major co-rotating twin-screw extruder brands globally.
A: Standard HC276 offers excellent corrosion resistance but suffers from low hardness (HRC22-26), leading to rapid mechanical wear. Our independently developed BLM6 matches the corrosion resistance of HC276 but significantly boosts hardness to HRC40-45, making it the ultimate solution for wear-and-corrosion applications.
A: Unlike traditional sintering which can leave micro-porosities, our advanced spray welding creates a highly dense alloy layer. This allows the hardness to exceed 56 HRC, increasing the continuous working life of the elements by 3 to 5 times compared to ordinary market alternatives.
