Preform Manufacturing Machine

Modern Injection molding machine has the characteristics of complex products, less processing and more plastic types. In the rise of the plastic industry today, the development of ZOWEITE® Preform Manufacturing Machine is very rapid. The special Preform Manufacturing Machine developed by ZOWIETE is equipped with a special screw, with the characteristics of stable high speed plasticity, suitable for mineral water PET preform, beverage PET preform, oil pot PET preform etc.

What are the characteristics of the Preform Manufacturing Machine?

● Using PET special screw, the melting speed and injection volume were significantly and improved, the plastic stability and acid value were reduced, the bottle billet shrinkage rate was effectively improved, and the light transmittance was high;

● Variable pump control system is 20%-30% higher over conventional machine tools, and servo control system is 30%-50% higher than conventional machine tools;

● Increase the pressure on the top and the top trip to meet the top requirements;

● Preform Manufacturing Machine locking parts fully enclosed metal plate structure, meeting the requirements of hygiene and temperature control;

● Preform Manufacturing Machine has a heat flow channel control interface;

● Choosing and matching a synchronous pressure protection system can increase the capacity by 15%-25%;

● Independent Preform Manufacturing Machine ensures smooth operation, accurate and fast positioning, effectively protects the mold and meets the requirements of mechanical hand taking;

● Plastic and injection independent mechanism is designed to synchronize plasticity and injection to ensure the application of large injection volume and shorten the production cycle.

What should the PET preform need to pay attention to when making the injection molding?

● Before the Preform Manufacturing Machine , the material can be dry for three of four hours to prevent the moisture in the PET preform from exceeding the limit of affecting the quality of the product.

●ZOWEITE®  Preform Manufacturing Machine template and mold need to be separated by heat insulation plate, injection molding should have enough exhaust to prevent rupture problems.

● The melt glue temperature of the Preform Manufacturing Machine is controlled at 270-295℃. The injection molding can be measured by the air injection method.

● The back pressure of Preform Manufacturing Machine shall be less than 100bar to prevent wear during bottle injection.
