We know the raw materials and mandrel composition of the winding forming technology of the spiral winding machine, and then we will learn about the core mold material and the third element in the future: spiral wound pipe machine winding molding technology winding machine. This component is also very important.


Here is the content list:

Mandrel material

Winding machine



Mandrel material

There are two types of spiral wound pipe machine mandrel materials: melting and soluble materials and assembled materials. Melting and soluble materials refer to paraffin, water-soluble polyvinyl alcohol molding sand, low melting point metals, etc. These materials can be made into hollow or solid core molds with the spiral wound pipe machine winding casting method. After spiral wound pipe machine winding products are wound, they can be wound from the opening. Pass hot water or high-pressure steam into the place to dissolve and melt, and then flow out from the product. The outflow of the solution is reused after cooling. Commonly used spiral wound pipe machines for assembled mandrels are aluminum, steel, sandwich structure, wood, and plaster. In addition, there are lining spiral wound pipe machine materials. The lining material is a component of the product and will not be taken out of the product after curing. The function of the lining material is mainly anti-corrosion and sealing. Of course, a spiral wound pipe machine can also play the role of a core mold. The outflow of the solution is reused after cooling. Rubber, plastic, stainless steel and aluminum alloy, etc.


Winding machine

The winding machine is the main equipment to realize the winding forming process of the spiral wound pipe machine. The requirements for the winding machine are: ①It can realize the winding rule of the spiral wound pipe machine winding product design and the accuracy of the yarn arrangement; ②The spiral wound pipe machine is easy to operate; ③Spiral wound Pipe machine winding production efficiency is high; ④Spiral wound pipe machine winding equipment is low in cost.


The spiral wound pipe machine is mainly composed of two parts: core die drive and wire winding nozzle drive. To eliminate the fiber loosening when the winding nozzle of the spiral wound pipe machine moves in the reverse direction, keep the tension stable and arrange the yarn tape accurately in the head or the tapered spiral wound pipe machine to achieve a small winding angle (0°~15 °) Winding, the spiral wound pipe machine is designed with a transverse feed (extending arm) mechanism perpendicular to the mandrel direction. To prevent the yarn from rotating when the winding nozzle of the spiral wound pipe machine moves in the reverse direction, the extension arm is equipped with a mechanism that can turn the winding nozzle of the spiral wound pipe machine.
