AL-500LL-50S which is the latest AL series model developed by Aoki. AL series has achieved innovative molding cycle time efficiency, and the product has been upgraded on the basis of the original widely used machine SBIII-250LL-50S. AL series can meet the diversified demands of the market in the near future, and a more suitable plasticizing device is combined to meet the needs of the products. It is characterized by high added value: high speed mold release, high plasticization, flexibility. High Speed Mold Release Is a forming method in Which Directional Blow Molding Theory And Bottle Preform Thickness Determine The Molding Cycle Time, Which Can Shorten The Injection Molding And Cooling Time As Much As Possible And Increase The Production By Leaps And Bounds. High Plasticization Is molded at low temperature to achieve high plasticizability, reduce the resin temperature when molding bottle preform, shorten the cooling time of injection molding, and achieve a better state of molten resin in the state of low speed rotation by improving melting and mixing properties. It is helpful to improve the formability of many kinds of molding materials. Flexibility Standard can be equipped with screw diameter φ 72 "(injection capacity is 661.6cm ³/ shot) or diameter φ 78" (injection capacity is 776.5cm ³/ shot) large capacity screw, even small specific gravity pp, hdpe and ultra-thick-walled containers can limit the number of mold cavities without the limit of injection capacity. It is obvious especially in the industries such as sports water bottles made of tritan/pp and the ultra-thick-walled cosmetic containers with glass texture such as petg/pcta/pctg.
