HDPE Pipe Welding Machine Technology Is Increasingly Widely Used


With the rapid development of the material industry, which is light weight, small friction, corrosion resistance, easy processing of plastic and its metal composite materials by the people's attention. Plastic products, has penetrated into the daily life of various fields, but also widely used in aviation, shipbuilding, automotive, electrical, packaging, toys, electronics, textiles and other industries. However, due to the injection molding process and other factors, in a considerable part of the shape of the complex plastic products can not be a single injection molding, which requires bonding, and the use of plastic bonding and heat treatment process is quite backward, not only inefficient, and bonding Agents also have a certain poison *, causing environmental pollution and labor protection and other issues. The traditional process of this technology can not be applied to the development of modern plastics industry needs, so a new plastic processing technology - HDPE Pipe Welding Machine with its efficient, high quality, beautiful, energy saving and other advantages * stand out. HDPE Pipe Welding Machine in the welding of plastic products, that is, do not fill any adhesive, filler or solvent, do not consume a lot of heat, with easy operation, welding speed, high welding strength, high production efficiency. As a result, ultrasonic welding technology has become increasingly widely used.

Во-первых, принцип работы аппарата для сварки труб HDPE

When the ultrasonic effect on the thermoplastic * plastic contact surface, will produce tens of thousands of times per second high-frequency vibration, this to achieve a certain amplitude of high-frequency vibration, through the welding pieces of ultrasonic energy to the welding area, That is, the intersection of two welding at the interface of large resistance, it will produce local high temperature. And because the plastic heat * poor, sometimes can not be distributed in time, gathered in the welding area, resulting in the rapid contact of the two plastic surface, with a certain pressure, to integrate into one. When the ultrasonic stops, let the pressure last for a few seconds to make it solidified, thus forming a solid molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of raw materials. HDPE Pipe Welding Machine depends on the quality of the transducer welding head amplitude, pressure and welding time and other three factors, welding time and welding head pressure can be adjusted, the amplitude determined by the transducer and horn. The three quantities have a suitable value with each other, the energy exceeds the appropriate value, the plastic melting amount is large, easy to deformation of welding; if the energy is small, it is not easy to solder, the pressure can not be increased. This optimum pressure is the product of the length of the welded part and the edge of the optimum pressure per 1mm.

Second, the HDPE Pipe Welding Machine method

1, welding ultrasonic vibration with the welding head will be ultrasonic conduction to the weld, due to the two welding parts at the large resistance, resulting in local high temperature, so that welding interface melting. Under a certain pressure, so that the two welding pieces to achieve beautiful, fast, strong welding effect.

2, заглубленные гайки или другой металл для вставки в пластиковые детали. Во-первых, ультразвуковая передача металла, высокоскоростная вибрация, так что металл непосредственно внедряется в литье пластмассы, в то время как пластика плавления, завершение завершения похоронен.

3, riveting method to metal and plastic or two different quality plastic joints together, you can use the ultrasonic riveting method, so that the weld is not brittle, beautiful, strong.

4, точечная сварка с использованием небольшой сварочной головки представляет собой двухточечную сварку двух больших пластиковых изделий или весь ряд зубоподобных сварочных головок непосредственно на двух пластиковых деталях, чтобы достичь эффекта точечной сварки.

5, forming the use of ultrasonic plastic parts instantly melt molding, when the plastic solidification can make metal or other materials, plastic solid.

6, удаление использования сварочной головки и основания специальной конструкции, когда пластиковая заготовка только что выстрелил, давление непосредственно на пластиковые ветви, через ультразвуковую проводимость для достижения эффекта резекции.
