Several important process parameters for PE Butt fusion welding machine
06 May 2021
Several important process parameters for PE Butt fusion welding machine ● Heating plate temperature refers to the surface temperature of the heating plate, generally measured with a surface thermometer. When measuring temperature, the influence of ambient temperature should be considered. (Except those already considered by the equipment) The temperature of the hot plate must not only ensure that the end surface of the pipe melts quickly, but also ensure that the welded pipe fittings do not degrade due to excessive temperature. ● Welding pressure The heating pressure is equivalent to the welding pressure. The function is to forcibly heat the pipe, remove the uneven part of the end of the pipe, so that all the end of the pipe is in contact with the heating plate, and the heat is evenly heated. To ● Crimping height Crimping height is used to measure the time that the heating pressure acts on the pipe section, that is, the degree of pressure and heating. To ● The heat absorption pressure ...
What are the advantages of automatic welding machines
25 Apr 2021
The automatic welding machine is now suitable for welding of stainless steel, gold, silver, alloy, steel, diamond and other materials, or welding of various materials. In use, we can see mobile phone batteries, sensors, medical equipment, and craft gifts. The emergence of this welding machine is used in industries such as clocks and watches, electronic components, sensors, precision machinery, and communications. The automatic welding machine mainly has the following characteristics: 1. It can realize spot welding, butt welding, stitch welding, sealing welding, etc. for thin-walled materials and precision parts. To 2. Because of the high laser power, the welding has a good aspect ratio, small deformation and fast welding speed. To 3. Good quality. This is obvious to all welders. It is flat, without porosity, and the welding material has strong toughness, which can be compared with the unmentioned material. To 4. Humanized design, LCD display, and button-based operation make it easier f...
Features and principles of automatic hot melt PE butt welding machine
20 Apr 2021
With the increasing application of PE pipes, the welding technology of PE pipes is attracting more and more attention. Pipe welding has been continuously improved. The important tool for pipe welding-hot melt PE butt welding machine has also experienced from manual to manual welding. Upgrade from semi-automatic to fully automatic. At present, there are mainly two types of hot-melt welding machines on the market, manual and hydraulic. The biggest drawback of these two hot-melt welding machines is that the welding quality is greatly affected by human factors. The quality of welding depends on the quality and quality of the operators. Experience, so welding cannot fundamentally guarantee welding quality. The biggest feature of the DHJA automatic hot melt welding machine is to minimize the influence of human factors on welding quality. It uses a computer to automatically and uninterruptedly monitor and control the time, pressure, temperature and other parameters of the entire welding proce...
Structural composition of plastic hot plate welding machine
12 Apr 2021
The plastic hot plate welding machine is composed of a pneumatic transmission part, a control part, an electrical part, a machine, a hot plate mold, and a mechanical device. 1. Pneumatic transmission part This part includes: filter, pressure reducing valve, lubricator, commutator, throttle valve, cylinder, etc. When the plastic hot plate welding machine is working, the stroke cylinder is first driven by an air compressor to drive the hot plate mold system to move up and down. The air pressure transmission is adjusted according to the welding plastic parts during the welding process of the hot plate welding machine. 2. Control part The control part is composed of PLC and temperature controller. The main functions are: One is to control the work of the pneumatic transmission system to open the gas circuit valve under timing control during welding. The cylinder pressurizes to lower the welding head and press the welded object with a certain pressure. After the welding is completed, the pr...
Types of Welders
06 Apr 2021
Welding machines are usually classified as constant current or constant voltage. A constant current machine varies its output voltage to maintain a steady current while a constant voltage machine fluctuates its output current to maintain a set voltage. These welding machines are generally used by professionals like welders. There are many types of welding machines available in the market which are used for different purposes like 3-Phase D.C. machines/ transformers and power packs, bench mounted spot/ projection welders, electronic controllers, integral transformer type spot welders, rocker arm spot welders, pedestal spot/projection welders, seam welders, special purpose welders/multi-spot welders, suspended spot welders and transformers, welding guns and many more. Rocker Arm Spot Welders is a very economic product and is used for general purpose fabrication needs of shops that handle M.S. boxes and sub-assemblies of size less than 1 m cube using sheets thinner than 2 mm. Air operated...
What is a hot melt hot plate welding machine
29 Mar 2021
What is a hot melt hot plate welding machine: The hot melt machine is widely used as a dedicated machine or used in conjunction with an automatic machine. It adopts a high-performance heater and a high-precision thermocouple, which can accurately control the heating temperature, and can stabilize and increase the processing efficiency. It is suitable for riveting, riveting, hot melt forming, hot melt cutting, metal screw embedding, LCD riveting forming between plastic and metal. Hot melt does not require very high product materials, and general plastics can basically be welded. After welding, the water and airtightness of the product can be guaranteed! The fastness can guarantee more than 80% of the body. Thermal melting is performed on the principle of electric heating. Its use is very wide. In addition to mobile phones, toys, computers, speakers, automobiles and other plastic industries, all products that need to be welded can be welded. The price is more favorable than ultrasonic, a...
