Professional manufacturers share you how to improve the life of plastic extruder screw

Screw is one of the core parts of the plastic extruder equipment. When we use extruder normally, the life of screw can sometimes restrict the service life of the equipment. So we need to know how to improve the life of the screw in the extruder.

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Since its establishment Fangli has been developed based on user’s demands. Through continuous improvement, independent R&D on the core technology and digestion & absorption of advanced technology and other means, we have developed PVC pipe extrusion line, PP-R pipe extrusion line, PE water supply / gas pipe extrusion line, which was recommended by the Chinese Ministry of Construction to replace imported products. We have gained the title of “First-class Brand in Zhejiang Province”.

The regular maintenance of plastic extruder equipment in daily use can make the equipment life longer. The simple maintenance contents are as follows:

I. To ensure that the driving parts can steadily provide power to the screw, the basic thing is to clean the relevant parts of the extruder. For example: lubricate the moving parts of the extruder, clean the iron filings or other impurities from the internal gear of the reducer after running, regularly replace the lubricating oil of the reducer, and record the equipment maintenance and wear.

II. Generally, when the customer uses the extruder after a certain period of time, we must carry out a comprehensive inspection of the equipment, and check the tightness of all the bolts. If the thread parts are damaged, they should be replaced immediately to prevent the equipment from failure during normal use, and relevant records should be made at the same time.

III. During normal use, regularly check the electrical instrument data, and do not overload the extruder equipment.

IV. If the power is suddenly cut off or the normal shutdown happens in production, when the conditions permit, we must reheat each section of the barrel to the specified temperature before starting again, and keep the material in the barrel heated uniformly for a certain period of time before starting.

We hope the above methods prepared for you on how to improve the life of the extruder screw can help you. If you have more needs, welcome to contact us, we will provide you with professional technical guidance and equipment procurement suggestions.
