Tinyard Enterprise Co.,Limited is one of the top level China injection molding machine manufacturers and suppliers,Website:http://www.tinyardmachine.com, welcome to wholesale injection molding machine from our factory.Introduction: To judge the PET preform's quality has some particular foundations, including blowing result, transparent degree, weight & dimension precision, Acetaldehyde (AA) levels, and so on. Part of them relate to the preform design, auxiliary equipment deploying and mold machining process, while, injection molding machine is also a very important factor. High injection capacity, large screw L/D ratio, powerful pump & heating capacity, low screw rotation speed, large ejection stroke are all required on injection molding machine for quality PET preform production. Aiming at PET preform injection's special requirement, Smargon Plastic has developed SMP series High-speed PET Preform Injection Molding Machine, which have combined superior PET injection performance, exceptional cost-effectiveness and application flexibility. With such machine, you can get perfect PET plastization result, low AA level of preform, and high output capacity with long time using life.Complete preform production line:Technology Parameters:ModelDH-180DH-228DH-280Screw Diameter55mm65mm75mmScrew L/D Ratio21:121:121:1Theoretical Shot Weight596g945g1228gInjection Pressure1584kg/m21454kg/m21572kg/m2Clamping force180tons228tons280tonsInjection Rate186cbm/s262cbm/s310cbm/sScrew Speed175rpm187rpm167rpmScrew Stroke260mm350mm410mmHeating Control Zone on Barrel4+14+15+1Opening Stroke452mm482mm550mmMold Thickness Range190-460mm210-510mm260-570mmEjection Stroke220mm250mm280mmTotal Power consumption31.4kw40.5kw52kwHeating Capacity13kw18.5kw22kwMachine Weight4.9tons6.5tons9.3tonsMachine dimension5.5 ×1.3×2.06.2 ×1.4×2.17.2 ×1.6 ×2.2
