PVC protection for the corner moldings, door edges, hard corner of the window construction of a new specially designed building materials. Is to protect the interior angle of yin and specially developed a new type of corner protection products, widely used in construction, decoration corner when enhancement and protection of the Company's production of PVC extrusion equipment moldings yin and mature technology, high degree of integration, automate the entire production process, easy to operate. In terms of raw material formulation, production equipment manufacturing, operation and training to provide comprehensive technical support to farmers passengers. Yield up: 100-150KG / H PVC moldings yin and extrusion equipment composition and characteristics of a high-speed mixer 2, 51 conical twin-screw extruder Host: host using high-precision hardened gear reducer, screw barrel high-strength alloy nitride (38CrMoALA) or high-strength alloy twin screw and long service life. Host AC variable frequency drive controller, no oil, low noise; precision screw feeders, belt out stirrer hopper, feed stable uniform choice of smart thermostat temperature controller, temperature control accuracy of ± 1 ℃; 3, Mold: One out of two molds, one can out of two, high yield, stable product size 4, shaping table: three-dimensional adjustment setting table, the length of four meters, electrically adjustable front and rear, 5.5KW two vacuum pumps, 3KW pumps one, true air Road 20 Road X2 = 40 road, cooling water: 20 Road X2 = 40 channels 5, duplex crawler tractor: duplex tractor, two separate traction motor drive belt, with a two molds can be adjusted independently (both frequency control) two product line speed, operation and PVC moldings yin and yang is more reasonable and stable molding process, improve product yield. 6, automatic continuous punching machine: The punching machine can be completed online continuously punching, punching accurate size, blurted less dander, security is good. 7, automatic cutting machine: pneumatic punching, alloy blades, automatic meter device, cutting length is adjustable, and is equipped with automatic feeding rack, without human splice.
