Prestressed spiral corrugated plastic pipe equipment Qingdao Cui 2000, after the company's technology continues to painstaking research, developed a new type of alternative products on the basis of prestressed plastic bellows on bamboo. The device contains several national patents. The device advantage; pipe, flat tube a machine operation. Low equipment investment costs, the production of bellows bellows than bamboo strong impact and so on. Compared with the same industry;. A production speed, twice the peer-class manufacturers. 2. Formulation of advanced technology, low cost, high quality. 3. Machine smooth operation, high reliability. And so on merit! ● All the equipment from SJ series single screw extruder extrusion die → → → vacuum spiral mold spray tank tractor → → → reverse sawing machine platform. ● comparison with plastic bellows equipment: prestressed plastic spiral prestressed corrugated plastic pipe ring stiffness S = 950N / m2 S = 800N / m2 minimum bend radius 0.9-1.5 meters (approximately 6-8 times the inside diameter or length of the shaft) 0.9-1.5 m (about 10-15 times the inside diameter or length of the shaft) outer wall smooth appearance, there is no parting line mold mold parting line of low cost, short changeover times, high efficiency, easy adjustment of the mold of high prices, changeover time long, adjust complex, requiring workers to operate a high level of connection can be used as a freshman specifications pipe fittings, screw connection, convenient, no fee tube, without adding any equipment must make joint injection molded parts, have to purchase the equipment or the Association to produce flat tube flat spiral tube mold technology parameters to be added: Host Model: SJ65 / 30, SJ70 / 33, SJ75 / 30, SJ80 / 30, SJ90 / 30, dies Specifications: φ40-φ150 (the largest producer diameter: φ230) Cooling: Traction speed: 0.5-3m / min pump power: 4kw pump power: 3kw Total power: 45kw unit weight 6500kg Dimensions (L × W × H): 20000 × 1200 × 1850
