Introduction to blown film machine

1、 Machine adaptation range

① Specialized for teaching in higher vocational colleges

② Research on New Materials and Material Modification in Polymer Laboratories of Higher Education Institutions

③ Plastic additive manufacturing enterprises, used for testing their product performance experiments

④ Color masterbatch production enterprises, used for testing the color separation and plasticization properties of their products in experiments

⑤ Color masterbatch sales company, used for making color samples for its customers

⑥ Large scale blown film factory, specialized in board making

⑦ Functional masterbatch production enterprises, used for testing the performance of their product functional masterbatch experiments (such as conductive masterbatch)

2、 Machine function

1. Test the "color separation" and "plasticization" of blown film colorants through blown film method

2. Modification testing of blown film materials

3、 Equipment parameters

⑴ Technical parameters of the machine

Main motor power: 2.2 KW Traction motor: 90W

Fan: 0.25 kW winding torque motor: 3.5N. m

Heating power: 5KW Screw diameter: Φ 20mm

Screw length to diameter ratio: 1:28 Die size: 4

Machine size: 1600x1200x800mm

With pulleys, it can move freely!

⑵ Production parameters

Minimum thickness of blown film: 0.01mm (i.e. one wire)

Blown film for large width: Low pressure material (HDPE) 200mm

High pressure material (LDPE) 180mm

Linear material (LLDPE) 180mm

Machine applicable materials: HDP, LDPE, LLDPE blown film grade PP+masterbatch, filling masterbatch, plastic additives, functional masterbatch

Applicable materials

The application materials are: low, medium, and high-end materials. For example, calcium carbonate filling can reach 60%; The secondary material of the color masterbatch can be used up to 35%, which is a plasticizing enhanced type,

Mold head configuration

Adopting high-pressure structural die head, optimized flow channel design

ƒ Screw structure

The screw adopts a high-pressure, double resistance material section structure design, and the screw structural parameters are modeled after Taiwan. It is processed and manufactured by "Zhoushan Huaye" Screw "(ranked among the top three in the national screw processing industry)
