Rotational molding and injection molding process of PE gas pipe: PE gas pipe is widely used in life now and has a wide range of applications. The rotomolding and injection molding process of PE gas pipe is the use of this processing method. The material is generally pulverized into powder, which is melted and flowed in the heat; The wear resistance of the pipe is 4 times that of the steel pipe. In the field of mud transportation, compared with steel pipes, HDPE pipes have wear resistance, which means that HDPE pipes have longer service life and economy; rotomolding uses two types of PE: general-purpose and cross-linkable. The product has high impact and small warpage, and its melt index range is generally 3-8. Higher MI grades are generally not suitable because they do not have the impact and environmental stress crack resistance desired for rotomoulded products. HDPE has countless applications ranging from reusable thin wall beverage cups to 5-gsl cans that consume 1/5 of the HDPE produced domestically. Injection molding grades generally have a melt index of 5 to 10, with lower fluidity grades with toughness and higher fluidity grades with processability.
