A.S.E.(XIAMEN) Manufacturing Co., LTD.

Ding Feng Spiral Technology Co. Ltd. (Short for “DFS”) is a joint venture co-founded by Advanced Spiral Technology Pty Ltd. (Short for “AST”) in Australia and A.S.E Manufacturing Co. Ltd. in China. This is an expansion of AST’s oversea business which will mainly focus on providing professional screw conveyor design service and sectional screw flight forming solutions.
AST was founded in ***7. Their co-founders Greg Bloxham and Scott Kelf took their fathers’ partnership named Scott Osmond Spiral, which had been making screw conveyors and other material handling equipment since ***0, to another level. Their material handling equipment company called Bulknet had been supplying  Australian market since late *0s. The years of experience in forming sectional screw flights and conveyors led to the R&D for a better system which we called TruHelix® that has been widely introduced to conveyor manufacturers, digging equipment manufacturers, water recycling equipment manufactures and etc. all around the world. This advanced technology has obtained patents in many countries including US and China.
Why this system is a game changer The traditional sectional flight forming process is either pulling or fixed die forming. They require a large number of dies to cover the various pitch, thickness and material. The handling and maintenance of the dies are time consuming and costly. For some particular shape of flights such as canting, it’s almost impossible for most of the manufacturers to make. The TruHelix® system not only can produce tapered ID&OD flights, canting flights but also can produce multi-step changing flights which can suit a complicated shaped inner shaft. Our system can produce flights from **0mm to ***0mm. The maximum thickness can go up to *0mm for carbon steel and *2mm for Abrasive Resistant steel. We tried to make one ***0mm diameter flight in *0mm thickness carbon steel. The forming took about 2mins. The whole process started from loading the flight blank into the machine, forming and final testing was less than 5mins.
