Regarding the engraving and welding of polypropylene sheet, the sheet is placed on the engraving machine, and the shape required by the customer is drawn by the software. After importing the special software for the engraving machine, with the cooperation of the software and the engraving machine, the cutter head of the engraving machine starts to cut in the order of the drawings, leaving the useful parts, which is the so-called polypropylene plate engraving.

Welding refers to the cut sheet, which needs to be formed into a box, heated to 180 degrees Celsius with a special hot air welding gun, and two polypropylene sheets are uniformly welded together with PP covered electrodes at high temperature, which plays a fixed role and has high strength. After soldering, there will be no leakage.

Polypropylene sheet, also known as polypropylene sheet, is formed by extrusion of polypropylene resin. Acid and alkali resistance, non-toxic, good physical and mechanical properties, polypropylene sheet processing is inseparable from PP coated electrode, and PP coated electrode is also called polypropylene plastic coated electrode, which needs to be heated with a special PP hot melt welding gun to 150- 180 ℃ to weld polypropylene plastic.
Polypropylene sheet
pp electrode is a long and thin plastic strip with parallel lines, commonly used as double-stranded and single-stranded. PP electrodes are used in various industries such as plastic welding, plastic chemical corrosion protection, plastic container welding, plastic pipe and plastic pipe fitting welding and electroplating equipment manufacturing. The product characteristics of pp welding rod are acid resistance, alkali resistance, non-corrosion and non-toxicity.

Another welding equipment is the pp welding torch. PP welding torches are conventionally used hand-held welding torches and extrusion welding torches, and different welding torches are used according to different welding requirements. For example, ordinary PP air duct welding can use hand-held welding torch, no matter which welding torch is used, PP electrode is used.

During welding, according to the different purposes to be achieved, there are generally three angles between the electrode and the weld (that is, the direction of movement of the electrode): obtuse angle, right angle, and acute angle. The seam is firm, and the front channel is generally used;

There are generally two welding methods: sheet and pipe, neither of which is easy to weld. Welding of polypropylene sheets requires chamfering before welding. Welding of pp pipes, such as welding pp pipes to flanges, also requires attention to speed and stability.
