Process control of PE-RT pipe extrusion production

Process flow: granular raw material → drying → extruder heating → special die for PE-RT pipe → vacuum calibrating tank → cooling tank → printing → high-speed haul-off → chip free cutting machine → coiler → inspection of appearance and size → simple packaging → pressure test → packaging after passing......

What are the general structural parameters of the screw

The common screw diameter D is 45-150 mm. With the increase of screw diameter and processing capacity, the productivity of extruder is directly proportional to the square of screw diameter D.

What is plastic extruder equipment?

What is plastic extruder equipment? Plastic extruder is also a kind of extruder. According to the extruded materials, it can be divided into two categories: plastic extruder and rubber extruder. The types of plastics extruded by general plastic extruders include PVC, PP, PE and other materials. The ......

Cooling water tank for plastic pipe molding

There are many auxiliary machines used in plastic extruder to extrude pipes, among which the more important auxiliary machine is cooling water tank. The auxiliary machine we use in the extruder production line is a kind of plastic auxiliary machine often used for extrusion plastic pipe. We generally......

Development trend of precision plastic extruder

After more than 100 years of development, plastic extruders have been derived from the original single screw into twin-screw, multi screw, or even non screw and other models. The plastic extruder (main machine) can be matched with various plastic molding auxiliary machines such as pipe, film, holdin......

Measures to solve the unstable current of the main machine of plastic extruder

Reasons for the unstable current of the main machine of plastic extruder: (1) Uneven feeding. (2) The main motor bearing is damaged or poorly lubricated. (3) A section of heater fails and does not heat. (4) The screw adjusting pad is wrong, or the phase is wrong, and the components interfere.
