Pipe Welding & Cutting Machines

What is Plastic Welding and What is Plastic Welding Used for?

Pipe welding machines & cutting machines are necessary for metal pipe procedure. The pipe cutting machine can cut plastic pipe fittings into different angles according to the needs of customers. The cutting angle is up to 67 degrees, using the Swedish saw blade and limited switch for safety. They are usually used for the production of Bends, Tees, Cross, Y welding fittings, and other fabrications. Pipe welding machines are suitable for HDPE/PP pipes and fittings, with high-quality aluminum casting without compromising strength and performance, high quality design provides for welding on the work site and at the factory.

What Plastic is Used for the Welding Machine for Plastic Pipes?

The plastic pipe welding machine is used to weld pipes made from PE, PP, and PVDF and can not be used to weld material without the description here, otherwise, the machine may be damaged or some accident may be resulted.


PE Material

Polyethylene is a thermoplastic resin prepared by polymerization of ethylene. In the industrial field, it also includes the copolymer of ethylene and some types of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low-temperature resistance, and good chemical stability, it can also withstand the erosion of most acids and bases. Polyethylene is insoluble in general solvents at room temperature, and it has low water absorption and excellent electrical insulation.


PP Material

Polypropylene is a polymer formed by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. Its melting point is 189 ℃ and the temperature range is -30mm 140 ℃. It is widely used in the production of fiber products such as clothing, blankets, medical devices, automobiles, chemical containers, etc., as well as food and drug packaging.


PVDF Material

PVDF, also known as fluoroplastic, is a kind of high-crystallization, high-performance geothermal plastic, and is suitable for a wide range of temperatures, and provides full security for high-temperature applications. Because of its good anti-ultraviolet properties, even if installed outdoors, ultraviolet radiation does not affect its life and material properties at all.


How to Use Plastic Pipe Welding Machine?

  1. Before welding, you should first check if the material, diameter, and wall thickness are in the required conditions. Secondly, check if there are scratches or fissures on the surface of pipes/fittings.

  2. Clean the inside and outside surfaces of pipe ends that are to be welded.

  3. Place the pipes/fittings in inserts of the frame. The pipe out of the basic framework should be supported by the same central axial of clamps. Fasten the screws of clamps to fix the pipes/fittings.

  4. Test the drag pressure: open the pressure regulation valve completely, lock the swing check valve tightly and then push forward the direction valve meanwhile adjusting the pressure regulation valve.

  5. Open the pressure regulation valve completely, lock the swing check valve tightly and then push forward the direction valve meanwhile adjust the pressure regulation valve to set the system pressure equal to drag pressure and add butting pressure.

  6. Separate the pipes/fittings end after turning the swing check valve in an anti-clockwise direction to relieve the pressure to the lowest.

  7. Close the pipes/fitting ends and check their alignment of them. The maximal misalignment should not exceed 10% of the wall thickness, and it could be improved by loosening or tightening the screws of clamps.

  8. Clear the dust or slit on the surface of the heating plate, and put the heating plate between the pipe ends after it reaches the required temperature. Close the pipes/fittings end.

  9. Turn the swing check valve anti-clockwise to reduce the pressure (not more than drag pressure) and turn the swing check valve in a clockwise direction to the end. Press the button “T2”.

  10. Open the frame and take out the heating plate and close two melting ends as quickly as possible.

  11. Keep the bar of direction valve in the close position for 2~3 minutes, put the bar of direction valve in the middle position, and press the button (“T5”) to count the cooling time until it is over.


Difference Between Plastic Welding And Fusion Welding

Plastic welding refers to the connection method that the contact surfaces of two plastic parts are fused at the same time by heating so that they are combined into a whole. Only applicable to thermoplastic connections. Welding rods can be used or not used during welding. When using the welding rod, the end face of the end to be welded shall be made into a fixed shape (such as U-shaped, X-shaped, etc.) joint, and the molten body of the welding rod drips into the joint, and the two welded parts are connected as a whole; When the welding rod is not used, the welding surface shall be heated and melted, and then the vertical pressure shall be applied to the welded surface until it is tightly fused.


The so-called fusion welding refers to the melting of the welded joint under the action of high temperature during the welding process. Since the welded parts are closely attached together, under the action of temperature field, gravity, etc., without pressure, the molten liquid melted by the two workpieces will mix. After the temperature decreases, the molten part condenses, and the two workpieces are firmly welded together to complete the welding method.
