Changshu smoothly da plastic products factory talk about PP plastic sheet under the heat welding method

Most of the PP plastic sheet can be used in a hot air welding. To get the best strength of weld, the electrode material must be the same as the base material. Typical hot air temperature is 350 degrees. Semi crystalline material typical hot air temperature is above the melting point of 80 degrees to 100 degrees. The movement of the welding tool speed usually is 0. 1 to 0. 3m/min。 Welding torch in the form of a pendulum move along axis of joint to obtain good results. The Angle between the electrode and welding parts should be close to 90 & deg; 。 A typical gas velocity range of 16 & ndash; — 60 litres per minute. Changshu well below da plastic products factory talk about PP plastic sheet under the heat welding method.



PP plastic plate heat welding method: using the hot gas may be air, or nitrogen and other inert gases ( Used for oxidation degradation of sensitive materials) 。 Gas and parts must be dry and free of dirt and grease. Parts edge should be chamfer before welding, or two parts form the corner. Two parts are within the fixture clamping, ensure the correct position. Hot gas welding is usually manual operation. Welders one hand welding tools, another hand to press the electrode into welding seam area. It is clear that the weld quality is very dependent on welding techniques. Using negative or roller modified welding tools, by increasing the control of the welding pressure, can improve the speed and quality of welding. ！
