PETG SPECIAL

Features

  • HMI Touch Screen, Incorporating with PLC system (Optional Siemens/B&R Control) for easy maintenance.
  • Blowing Unit/ Die Head movement for changing mold easily, as option.
  • Built with safety devices to provide maximum protection for the machine operator.
  • High plasticizing capacity extrusion screw is designed to handle material variations.
  • Plasticizing screw and barrel is precision machined from special nitrogen treated steel.
  • Water cooling technology controls feed zone temperature.
  • Chiller circulated hydraulically controlled blow-pin.
  • When requiring both functions in a single machine, purchase the machine for PETG application and

order the additional parts (screw and die head ) for conversion to PE application.

Features & Application

Polyethylene terephthalate glycol, commonly known as PETG or PET-G, is a thermoplastic polyester that provides

significant chemical resistance, durability, and excellent formability for manufacturing.

PETG is strong and cost-effective when compared to either acrylic or polycarbonate. Its unique characteristics make it

preferable for impact-resistant glazing and high strength display units. Suitable for digital printing, PETG lends itself to product materials, displays, and signage.

In general, PETG is a food-safe plastic that’s commonly used for food containers and bottles for liquid beverages. Like acrylic and

many other thermoplastics, PETG is fully recyclable.

PETG is both thermoformable and vacuum-formable, and can tolerate a tremendous amount of pressure without cracking. Although

PETG is naturally clear, it takes color easily during processing. It can be injection molded into a variety of shapes, or extruded into sheets.

PETG’s damage resistance is far higher than that of acrylic, to the point that it rivals the impact resistance of polycarbonate. However, PETG

fabricates easily, making it an easy material for both practitioners and professional fabricators.

Thermoforming– PETG does not require drying prior to forming and has rapid thermoforming cycle times. It is brake formable up to 0.080″ thickness.

Impact Resistance– PETG is less brittle than acrylic, and is a lower cost alternative to polycarbonate.

Chemical Resistance– PETG offers superior chemical resistance when compared with many other transparent plastics.

Base on all these characters of PETG plastic material, we developed this special blow molding machine only for PETG material.mostly, the application

are cosmetic jars or bottles or containers. as far as now, we are the No.1 on this PETG extrusion blow molding machine. see the bottles made by our extrusion blow machine:
