According to introducing, this technology uses warm-up and design of screw extruder unifinication, solder intensity is tall, sealed the effect is good. Be opposite especially broad welding line and ply is in the plastic products of 30 millimeter above, can solder figuration, intensity of welding line machinery is adjacent by solder matrix. Classics test, each index obtains the product completely Germany solders requirement of standard of normative DVS2209-1 technology, can rival with photograph of technology of German MUNSCL company, can satisfy domestic petrifaction to wait for the trade demand to large and anticorrosive equipment.
