In China's plastic machinery market, plastic extruder, as an important processing equipment, plays a pivotal role in the processing of products such as packing belts, plates, films, pellets, and profiles. The development of extruder processing technology has always been the focus and focus of the development of the plastic processing industry. For a long time, the development of its processing technology has directly affected the development of the plastic processing industry.
Eighty years ago, an exciting event happened in the plastics machinery industry-the first twin-screw extruder capable of producing polymers and processing them was born! Now eighty years have passed, twin-screw extrusion The machine has been widely used in PVC pipe, food industry, pharmaceutical industry and many other fields. After years of experience accumulation and research, the twin-screw extruder has been constantly innovating on its development path, bringing a double experience of vision and technology again and again.

Extruder is one of the types of plastic machinery. It is the most common machine in the modified plastics industry and is widely used in polymer processing and other production and processing fields. Extruder can be divided into single-screw extruder and twin-screw extruder. The working principles and application fields of the two are different, and both have advantages and disadvantages. [ Details ]
In recent years, China's plastic machinery industry has developed rapidly, and its success is obvious to all. However, if we delve into China's plastics machinery industry, we can see that China's plastics machinery manufacturing field accounts for a large portion of the mechanization field, the popularity of automated production is high, and the proportion of digital and intelligent production workshops lags behind automated workshops. Some professionals pointed out that the intelligentization of plastic processing workshop equipment in China must implement information, digital and Internet technologies, and truly equip plastic machine equipment with an "intelligent brain."

How to clean and change the color and material of the plastic extruder correctly?
Burning or roasting to remove the plastic fixed on the screw is the most common and effective method for plastic processing units, but the acetylene flame must never be used to clean the screw.
Structure and application of plastic machinery reciprocating single screw mixing extruder
Reciprocating single screw mixing extruder is one of the common plastic machinery equipment. In the processing of any polymer, it imparts certain processing characteristics to the polymer or gives the product specific use properties. It is often necessary to blend different polymers or mix polymers with various auxiliaries and pigments. Overcome some of the gel particles or unmelted resin that may be produced between molecules.

10 Principles of Extruder for Granulating Old Plastic Must Read!
The working mechanism of the screw extruder is to rely on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and uniformly mixed and formed through a die. Do you know the principles of plastic extrusion mentioned below?
Impact of Extruder Filter Screen on Products
During the extrusion process of the extruder, the molten material is conveyed to the mold through a filter screen. The filter screen allows the material to be filtered and can improve the mixing effect of the material. However, the filter screen can also cause fluctuations in the process, which can cause back pressure and the temperature of the molten material to rise and sometimes decrease.
How should the screw extruder be maintained?
The screw extruder maintenance process is generally divided into daily maintenance and regular maintenance: daily maintenance is a routine routine work, does not take up equipment operation hours, and is usually completed during startup. The focus is on cleaning the machine, lubricating all moving parts, tightening loose threaded parts, checking and adjusting the motor, controlling instruments, working parts and pipelines in a timely manner. Periodic maintenance is generally performed after the extruder is continuously operated for 2500-5000h. The machine needs to be disassembled to inspect, measure, and identify the wear of the main parts, replace parts that have reached the prescribed wear limit, and repair damaged parts.
ZE BASIC 62 twin screw extruder directly doubles bioplastics capacity
Techno's newly installed production line is the ZE BASIC 62 twin screw extruder with a maximum output rate of 800 kg / h. This extruder will double Techno's production capacity every year.
Extruder development trends and prospects
After more than 100 years of development, the plastic extruder has been derived from the original single screw, such as twin screw, multi-screw, and even no screw. The plastic extruder (host) can be used with various plastic molding auxiliary machines such as pipes, films, holding materials, monofilaments, flat filaments, packing belts, extruded nets, plates (sheets), profiles, pellets, and cable coatings. Match and form various plastic extrusion molding production lines to produce various plastic products.
What should I pay attention to when buying an extruder?
The widespread application of plastic products has promoted the rapid development of the plastics machine industry, and the extruder has an important position in the plastics machine industry. The extruder can be divided into single screw, twin screw and multi-screw extruder according to the number of screws. How to choose a satisfactory extruder and what needs to be paid attention to when purchasing an extruder have been a difficult problem for some users. Let's take a look at what needs to be paid attention to when choosing an extruder.
