PPR Pipes Production Line Plastic Tube Pipe Making Machine Plastic Extrusion Machine Energy Saving Extruder

Product Introduction

PP-R drinking water pipe system is a new type of product commonly used in developed countries in the world today. It uses homogeneous welding technology in cold and hot water transportation projects. Its comprehensive technical performance and economic indicators are far superior to other similar products, especially its excellent hygienic performance. The whole process from production and use to disposal can meet extremely high hygienic and environmental protection requirements. The product has the advantages of heat resistance, pressure resistance, heat preservation and energy saving, long service life and economy.

Equipment Composition and Characteristics

The PPR pipe production line produced by our company has advantages such as unique structure, high degree of automation, convenient operation, stable and reliable continuous production. The PPR pipe products produced by this line have the advantages of heat resistance, pressure resistance, heat preservation, energy saving, long service life and economy. This product has become a good material for home improvement water pipe renovation.

PPR Pipe Production Process

Raw material + color masterbatch → mixing →vacuum feeding → raw material drying → single-screw extruder → color line extruder → screw type mold → sizing sleeve → spray vacuum calibrating box → spray cooling water tank → jet printer → Caterpillar tractor → finished product testing and packaging.

Problems Encountered in the Production Process of PPR Pipes and Possible Reasons

1. The inner wall of the tube is uneven:

The temperature of the screw is too high.

The screw speed is too fast.

2. There are bubbles on the inner wall of the tube:

The material is damp.

3. Uneven wall thickness:

The die and mandrel are not aligned.

The temperature of the machine head is uneven.

Traction is unstable.

Compressed air is unstable.

4. Pipe bending:

The wall thickness of the pipe is uneven.

The temperature around the machine head is uneven.

The cooling groove of the machine head and the traction cutting center are not aligned.

The holes at both ends of the cooling groove are not concentric.

5. The product is brittle:

The degree of plasticization of the fuselage is not enough.

The screw speed is too fast.

Head temperature is too low.

Resin viscosity is too high.

6. The longitudinal or transverse shrinkage of the pipe is large:

The radial difference between the sizing sleeve and the inner diameter of the die is large (transverse).

High traction speed (longitudinal).

7. Sudden slow discharge:

The temperature of the feeding section of the screw is high.

Water has entered the fuselage.

The melt pressure of the machine head is small.
