Pipe Reducing Machines

After filled MGO powder by filling machine to the heater elements, we need to reduce the pipes byreducing machine. There are so many pipe reducing machine in tubemachines, which kind of pipe reducing machines we need?

Generally speaking, we can find two styles of pipe reducing machines: that is pipe reducing machines for industrial, and pipe reducing machines for home appliances. The industrial pipe reducing machines minaly included swaging machine, double hammer hammer roll reducing machine and rolling mill. While home appliances pipe reducing machines included SG8A, SG8B, SG12A, SG12B.

Besides, we can also find different reduced shape machines, that is square/flat shape pipe reducing machine, and round pipe reducing machine. When we need to reduced square pipes or flat pipes, usually, we need to reduce the tubes into round shape, and then reduce to square / flat shape. To reduced the pipes into square or flat shape, it need to use SDG30 double hammer roll reducing machine. However, if need to reduce the pipes into round shape, it will depend on what styles of heaters and how many need to reduce. For example, if need to make cartridge heaters, then use DG30 swaging machine will be ok.

Further more, we can find SG8A, SG8B, SG12A,SG12 B for round tube reducing. What is the difference among these pipe reducing machines? Style A pipe reducing machine will works more quite than style B. While style B tube reducing machine can reduce biger sizes tubes than style A.

machines for heaters

With the development of electrical equipment widely used in home and industry, the demand of heater tubular - a main accessory among electrical appliances, also increase. To produce heater tubular, it not only require technology, but also heater equipment. What machinery need to produce heaters? Where can we buy machines for heaters? Which equipment will be suitable for heater tubular?Zhaoqing City Feihong Machinery & Electrical Co., Ltd has more than 20 years in heating machinery manufacturing. It is one of the leading heater equipment factory in China. Welcome to tubemachines.com for heater machines.

So, what machines need to produce heaters? Generally speaking, the heater equipment will depend on what kinds of heaters need to produce. According to different shapes of the heaters, we can find cartridge heatersand double head heater tubulars. Besides, if divided into the use, there are industrial heaters and civil heaterscan be found. Nowdays, Hot runner heater tubular and cartridge heaters are very hot in China.

Though the technology to produce heaters will be a little among different factories, so the machines may be a little different. However, below steps are main steps to produces heaters:

1. Cutting Pipe: cut the empty pipes into the length needed by tube cutting machine;

2. Coil the resistance wire: coil wind the resistance wire by winding machine, or on the magnesium bar, ceramic bar or mica sheet;

3. Fill Mgo Powder: put the resistance into the tube, then fill MGO powder by filling machine.

4. Reduce the pipe: shrink the pipes by pipe reducing machine, to make the MGO powder in higher density.

5. Cutting the end of the pipes: use small lathe to cut the end of the tubes.

6. Annealing the heaters: annealing the heaters by heat treatment equipment for later bending step.

7. Dig MGO powder: Dip the MGO powder at the mouth of the heaters.

8.Rod cutting: small punch to make electricity connecting ends of the two lead as long;

9. Inspection 1: high voltage meter, meter resistance, high-pressure tape detection tube, resistance value and size;

10. oven or electric oven temperature humidity discharging, small lathe for turning the head of the roll.

11. polishing machine to polish ends;

12 . inspection 2: check the polishing quality;

13. welding: welding pipe and casing argon arc welding machine (fasteners);

14: forming tubes: bend pipe by bending machine;

15. oven moisture exhaust, the insulating surface detect insulation performance;

16. polishing machine to polish the heaters

17. electric welding machine to weld.

18. sealing, moisture;

19. final inspection: high voltage meter.

Machines for Cartridge Heaters

What machines need to make cartridge heaters? Where can we buy cartridge heaters machines? Is there a heating machines factory for cartridge heaters in China? Zhaoqing Feihong is a leading heating machines factory in China. Welcome to contact us by email to may@zqfeihong.com for machines details. 

Many heaters factory ask us"what machines needed to produce cartridge heaters?" As a leading cartridge heaters machines factory in China, we would like to share our machines to make cartrdge heaters with you.

A cartridge heater is a tube-shaped, heavy-duty, industrial joule heating element (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density,based on its intended application.  Highly compacted they reach a surface watt density of up to 50 W/cm².

It may be used to heat any kind of substance or material, such as oil, air, or sugar. However, a common application are plastic pellets, which are melted in order to form molded plastic parts. An example of such a process is the "hot runner" process. Cartridge heaters resemble tubular heaters structurally but tend to have higher watt densities.

To make cartridge heaters, you mainly need below machines:

pipe cutting machine - cut the tubes according to the length needed

Welding machine - welding the heater tubes

DRS-23 PLC resistance coil winding machine - coil the resistance wire

MGO powder filling machine - fill MGO powder to the tube

DG30 sawging machine - reduce the tubes after filled MGO powder, to make the density higher

polishing machine - polish the tube, to make the heaters surface more slick.
