Key Parts of pp hollow sheet extrusion line factory

1. Extruder

Specially designed extruder screw and advanced temperature control system retain the plastic properties of the polycarbonate resin while ensuring extrusion efficiency. High energy efficiency is a major benefit of this PC sheet extruder. The extruder motor consumes 20% less power than an equivalent motor made by our competitors.

2. Extrusion Die

High quality alloy extrusion die lip and choker bar provides uniform pressure drop from die inlet to die lip. Precisely machined die assures good quality of finished extruded sheet.

3. Vacuum Calibration Table

The thermal convection system of the calibration table features an intersection arrangement which ensures the hot PC resin flow is effectively cooled and the final extrudate achieves the desired shape and accurate dimensions. As far as the shape forming process is concerned, our multiwall sheet extrusion machinery allows rapid shape formation through sizing and cooling without the need of cold water. It helps save energy and improves efficiency.

4. Dry Vacuum Calibrator

The vacuum calibrator consists of 2 independent sub-systems, which are equipped with many close-loop vacuum channels.

5. Electrical Control System

Programmable logic control (PLC) ensures precise extrusion process parameters and optimized operation features.

FAQ 1: How long can the PP plastic hollow sheet production line be used?

The price of a PP plastic hollow sheet production line ranges from tens of thousands to millions, so for such expensive equipment, its service life naturally becomes the focus of attention.

Everyone knows that the longer the service life of a production line, the more revenue it can bring, but how long does its service life really last? Normally, the service life of a PP plastic hollow sheet production line is about 15-30 years, and the specific service life is directly related to the quality of the equipment itself and everyone's usage habits.

The equipment quality of the PP plastic hollow sheet production line is the basis for determining the length of its service life. Some manufacturers use components with poor quality during equipment production, which often leads to malfunctions and seriously affects the service life of the entire production line.

The usage habits of the production line include maintenance, reasonable operation, reasonable adjustment of production processes, regular replacement of vulnerable parts, etc. If everyone can do these points well in the use of the production line, it can also extend the service life of the production line and generate more profits.

FAQ 2: What is the scrap rate of PP plastic hollow sheet production line?

To understand the scrap rate of PP plastic hollow sheet production line, first we need to know the calculation method of scrap rate and the factors that affect it.

The calculation method of scrap rate is that the quantity of scrap per unit time ÷ total output=scrap rate

There are three main factors that affect the scrap rate: first, raw materials; second, the proficiency of the operator; and third, the performance of the equipment.

We won't introduce the raw materials because each customer may use different raw materials, which can only be explored by everyone themselves.

The more skilled the operator is at turning on the equipment, the smoother it can be turned on and put into normal production. Moreover, the waste rate of the PP plastic hollow sheet production line mainly occurs during the startup process, and once the startup is successful, there is basically no waste generated afterwards.

With over 30 years of research and production experience, our PP plastic hollow sheet production line is easy to start and operate. Compared with peers, our equipment has more stable performance and a lower possibility of failure during normal operation.

At present, customers have reported that the scrap rate of our products generally does not exceed 0.2%, which has a significant advantage in competition among peers and can also bring more economic benefits to customers.
