Introduction Recently, the China Light Industry Top 100 Enterprises Summit Forum was held in Beijing. At the forum, Li Yuzhong, vice chairman of China National Light Industry Council, announced the “Announcement on Evaluation Results of China’s Top 50 Enterprises in the Equipment Manufacturing Industry of China’s Light Industry”. Fifty companies including Shanghai JWELL Machine Manufacturing

Suzhou JWELL is a high-tech manufacturer dedicated to the development and manufacturing of plastic pipe extrusion molding equipment. The factory covers an area of more than 400 acres. The company has a high-quality R&D team and an experienced team of mechanical and electrical commissioning engineers, as well as a mechanical processing base and a standardized

Time flies. On December 1st, the 30th Turkish International Plastics and Rubber Machinery Industry Exhibition Plaseurasia2021 opened at the Istanbul International Exhibition Center at the end of 2021. Affected by the epidemic, it has caused a big blow to international exchanges, especially for many companies planning to participate in overseas exhibitions. However, at this important

Plastic extrusion moulding, such as UPVC (Rigid Polyvinyl Chloride) profile or pipe product moulding, is mainly formed through the compounding of PVC resin and related additives, extrusion moulding, shaping, traction, and cutting. Among them, raw materials, formula equipment and operating processes are the main factors of plastic extrusion moulding, directly affecting the quality and output

During the production and operation of the plastic granulator, it must strictly implement according to the standards to extend its service life. How can the plastic granulator be used for a long time? Never use low-quality recycled materials with metal impurities or silt. Do not place metal objects that may fall near the feed inlet.

The extrusion process of PVC wood plastic is generally influenced by the factors of forming temperature, screw speed, metering feeding speed, traction speed, working pressure of extruder, exhaust gas, and vacuum cooling. However, the extrusion process is related to the formulation system, extruder structure and performance, product shape, mold design, product quality requirements, and public

Correct and reasonable use of PVC pipe extruder machine can give full play to the machine’s efficiency, maintain good working conditions, and extend the machine’s service life. The use of PVC pipe extruder machine includes a series of links such as machine installation, adjustment, test run, operation, maintenance and repair. Its use has the typical

1. Production Of Disposable Lunch Boxes With Degradable Materials 1. Fully biodegradable material lunch box: using PLA+PBS+biomass/minerals and other modified materials can produce a high temperature-resistant fully biodegradable material lunch box. There are two process methods: Two-step method: The raw materials are firstly filled with modified pellets, then extruded and thermoformed, using an ordinary single-screw

Preparatory steps before starting the sheet extrusion line Pre-dry the pellets of the extruded profile and further dry if necessary. Check whether the components, water, and air systems are in a standard, safe and reliable state. The parts that need lubrication should have sufficient lubricating oil. The running part should regularly fille with lubricating oil.

The principle of the bottle blowing machine The blowing process of the bottle blowing machine is divided into two parts. 1. Warm-up An infrared high-temperature lamp irradiates the preform to heat and soften the preform. To maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a particular

The density, hardness, and gloss of the plastic can be reduced or increased by appropriate methods to reduce or increase the plastic’s initial relative density, increase the hardness or increase the flexibility, and change the gloss to meet the needs of different applications. 1. How to reduce the density of plastic? Reducing plastic density refers

The extruder is an essential piece of equipment for plastic molding processing and pelletizing. The extruder’s everyday use can give full play to the machine’s efficiency and maintain an excellent working condition. It must carefully keep unremittingly to extend the service life of the appliance. The extruder’s primary failure is abnormal noise and abnormal vibration

During the pipe extrusion process, gas needs to vent from the melt. If these gases cannot discharge in time, defects such as pores, bubbles, and surface dullness may appear on the surface or inside the pipe products, seriously affecting the physical and mechanical properties, chemical properties, and electrical properties pipe. There are 1 to 2

A spinning machine is a machine that makes a fiber-forming polymer solution or melts from filaments. According to different fiber spinning methods, spinning machines are divided into three types: wet spinning machine, melt spinning machine, and dry spinning machine. Wet spinning machine Suitable for spinning viscose fiber, acrylic fiber, nylon, etc. The main feature is

In the plastic pipe production line, the operator’s unskilled technology and the machine operation will cause the plastic pipe to appear rough on the outer surface, jitter ring inside, uneven wall thickness, insufficient roundness and so on. Therefore, timely adjustment of plastic pipes’ production process and troubleshooting of the plastic pipe production line can improve
