How to weld plastic pipes with Plastic pipe welding machine?
The plastic pipe connection adopts butt welding, mainly using a set of Plastic pipe welding machine. The equipment is mainly composed of air compressor, air filter, power supply, voltage regulator and welding torch electrode.
The working principle of the plastic pipe welding machine: the air compressor runs, and the air with a certain pressure is passed through the filter to remove the oil and moisture (the oil is mainly mixed with some lubricating oil during the operation of the air compressor, and the moisture mainly comes from the air ), enter for multiple sets of torches
Air divider used. Connect the hose from the air distributor to the air inlet connector of the welding torch, and then connect the power cord through the voltage regulator to the wiring port of the resistance wire of the welding torch. The heat generated by the resistance wire will be heated by the air of the welding torch after being energized, and the heating temperature can be controlled by the voltage regulator.
When the temperature rises to about 250°C, the welded plastic nozzle will melt, and the welding can be carried out in the same way as the ordinary gas welding process. The electrode is made of the same plastic electrode as the base metal.
When laying pipelines in Pakistan, the above are the general construction steps.
Matters needing attention when welding plastic pipes
The pipe end with larger pipe diameter should be beveled.
The operator should adjust the compressed air pressure and the voltage of the pressure regulator according to the wall thickness of the pipe and control the air volume of the welding torch to achieve an optimal temperature and airflow speed to ensure the welding quality.
The diameter of the electrode should be selected according to the wall thickness of the pipe. During welding, two welds are used (i.e., one for the bottom and one for the cover), and the position of the weld joint is staggered. When the pipe diameter is small, one welding can be used. seams, but should be welded through.
The welding speed should be uniform, and the appearance of the welding seam should be beautiful and straight.
What does the plastic pipe welding machine mainly weld?
Can weld metal and plastic products
However, due to the different wavelengths of plastic laser welders and metal laser welders, the relative difficulty of plastic and metal welding is also quite high, and it is also affected by material properties;
It can also weld soft and hard PVC, high-density polyethylene, polypropylene, low-density polyethylene and other plastic products. However, not all plastics can be welded, and it is also affected by the thickness of the plastic, the light transmittance of the plastic, and the material properties of the plastic itself.
In the Pakistani market, there will be a larger market for multi-functional welding equipment.
Plastic pipe welding machine in Pakistan
Different Plastic pipe welding machines are required for different plastic pipe welding projects. We cannot generalize. The performance of the plastic welding machine in Pakistan depends on the price. If the performance is particularly high, it is necessary to have a certain ability to bear the price of the Plastic pipe welding machine. A good-quality plastic pipe welding machine can work stably and continuously sometimes under overload. Of course, we do not recommend doing this, as it will damage the life of the equipment over time.
Price of a Plastic pipe welding machine in Pakistan.
1. The price of ultrasonic plastic pipe welding machine
Plastic pipe welding machine converts 50/60 Hz current into 15, 20, 30 or 40 kHz electrical energy through an ultrasonic generator. The converted high-frequency electrical energy is converted into mechanical motion of the same frequency again by the transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded, where the vibration energy is converted into heat energy by friction, melting the plastic. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer/modulator/horn triplet, die and frame.
The price of an ultrasonic Plastic pipe welding machine in Pakistan is generally between $2,000 and $3,500.
2. The price of rotary friction plastic pipe welding machine
Rotary friction plastic pipe welding machines are generally used to weld two round thermoplastic workpieces. During welding, one workpiece is fixed on the bottom mold, and the other workpiece rotates on the surface of the fixed workpiece. Due to a certain pressure acting on the two workpieces, the heat generated by the friction between the workpieces can melt the contact surfaces of the two workpieces and form a forbidden and airtight bond. Among them, the positioning spin fusion is to rotate at the set time and stop at the set position instantly, becoming a permanent fusion
The price of a rotary friction plastic pipe welding machine in Pakistan is generally between $1,000 and $8,000. The specific price depends on the power and other related parameters of the equipment.
3. Price of hot plate Plastic pipe welding machine
Plastic pipe welding machines mainly weld plastic parts through a temperature-controlled heating plate. When welding, the heating plate is placed between two plastic parts, and when the workpiece is pressed against the heating plate, the plastic begins to melt. After a pre-set heating time has passed, the plastic on the surface of the workpiece will reach a certain degree of melting. At this time, the workpiece will be separated to both sides, the heating plate will be removed, and then the two workpieces will be merged together. When a certain welding time and After the welding depth, the entire welding process is completed.
The price of a hot plate plastic tube welding machine in Pakistan is generally between $3,000 and $4,000.
4. The price of laser plastic pipe welding machine
Plastic pipe welding machine is to make light/laser rays pass through one plastic part and irradiate the surface of another plastic part (that is, the welding surface); after fully absorbing the beam energy, the welding surface is heated and melted; An adjustable clamping force keeps it tightly together. Compared with other existing plastic welding processes, the advantage of the laser welding process is that the light/laser rays can heat and weld the entire welding surface at the same time, and the welding effect is more remarkable.
The price of a laser plastic welding machine in Pakistan is generally between $600 and $3,000.
5. The price of orbital vibration friction welding machine
Orbital vibration friction welding is a method of welding that utilizes frictional heat energy. During orbital vibration friction welding, the upper workpiece orbits at a constant speed - a circular motion in all directions. Movement can generate thermal energy that brings the welded part of the two plastic parts to the melting point. Once the plastic begins to melt, the movement stops and the welded parts of the two workpieces solidify and firmly join together. The small clamping force results in minimal deformation of the workpiece, and workpieces up to 10 inches in diameter can be welded with applied orbital vibration friction.
The price of an orbital vibration friction welding machine in Pakistan is generally $800 to $2500.
6. The price of linear vibration friction Plastic pipe welding machine
Plastic pipe welding machine uses the frictional heat energy generated on the contact surface of two workpieces to be welded to melt plastic through linear vibration friction welding. The thermal energy comes from the reciprocating movement of a workpiece on the other surface with a certain displacement or amplitude under a certain pressure. Once the desired degree of welding is achieved, the vibration will stop, while a certain amount of pressure will still be exerted on the two workpieces, allowing the just welded part to cool and solidify to form a tight bond.
The price of a Plastic pipe welding machine in Pakistan is about $500 to $2300.
The specific price of a plastic welding machine in Pakistan should still be consulted by our professional engineers. When you are choosing a plastic welding machine, if you use it yourself, you can recommend the specific model of the plastic pipe you are constructing to the plastic welding machine you want; if you are in the plastic welding machine business, you can recommend you to purchase in bulk Welding machine, give you the best purchase solution and competitive price.
