Spiral tubefomer
The spiral tubeformer is divided into molding type and steel strip type . The molding of corresponding size must be used for each size of spiral air pipe. For the steel strip type,adopt different specifications and lengths of steel strip, can process the corresponding size of air duct.
Spiral Tubeformer Aluminum Mold Type
Cutting method is roller cutting,no spark,no burr,no noise with smooth surface.Using three sets of forming wheels,the mold is aluminum alloy with fast forming speed, stable performance and fast mold changing High production efficiency. The air duct made of small air supply resistance, high strength and good sealing performance.



The module technique gives the customer the possibility to choose between a number of options, allowing him to create a machine a number of options, allowing him to create a machine for his specific needs. The frequency controlled main drive ensures a smooth acceleration and an almost noiseless operation. The outstanding patented flying slitter cuts the tubes to lengthwithout noise or hot sparks as known from the saws and provides smooth tube ends without deburring.
The design and options fulfill the needs in HVAC to produce in mild steel, galvanized steel, stainless steel or aluminum
The corrugation unit allows a reduction in material costs and makes the bigger diameter tubes more rigid.
