The future development direction of foam granulator

At present, recycled foam particles have been applied in textiles, automobiles, food and beverage packaging, and consumer electronics. This has also driven the development of the foam granulator industry to move forward steadily. However, there is still a shortage of technology in the foam granulator industry in China, and the exploration and development of new technology roads is still very long.

The road to domestic technology shortage is long and difficult

However, due to the shortage of domestic production technology, the production process is inferior to foreign products. Therefore, the domestic foam granulator production line still has a certain gap with respect to foreign countries. There are still many shortcomings in domestic products, and the number of imported plastic machinery is also growing rapidly. Therefore, the development of the domestic foam granulator production line is long and difficult.

The 21st century is a century of environmental protection. Environmental issues are becoming more and more important. Resources and energy are more tense. In order to meet the requirements of the new era, foam granulators must be adhered to in order to meet the increasing demands of the market for packaging quality and quantity. Point of departure.

With the continuous development of new materials, new products and new processes of foam granulators, more and more foam granulator production lines are developing towards multi-functional and multi-environmental development, and continue to expand into other application fields. In order to have a wider range of applications, foam granulators must have better production performance and research and development capabilities, and higher quality production processes to meet the needs of the waste recycling industry.

The next four development directions

Efficient and multi-functional: The efficiency of plastic machinery is mainly reflected in high output, low energy consumption and low manufacturing cost. In terms of functions, screw extruders have been used not only for extrusion molding and mixing of polymer materials, but also for applications such as food, feed, electrodes, explosives, building materials, packaging, pulp, and ceramics. In addition, the "one-step extrusion process" in which the kneading granulation and the extrusion molding process are combined into one is also worthy of attention.

Large-scale and precision: The realization of large-scale plastic machinery and equipment can reduce production costs, which is more obvious in large-scale twin-screw foam granulators, blown film units, and pipe extrusion units. The precision can improve the gold content of the product. For example, multi-layer co-extruded composite film needs precision extrusion, and as an important means to achieve precision extrusion, the melt gear pump must be intensively developed and researched.

Modularization and specialization: modular production can adapt to the special requirements of different users, shorten the development cycle of new products, and strive for a larger market share; and specialized production can arrange the various system module components of extrusion molding equipment to be fixed-point production or even Global sourcing is very beneficial to ensure the quality of the entire period, reduce costs and accelerate capital turnover.

Intelligent and networked: Foam granulators in developed countries have adopted modern electronic and computer control technologies, process parameters such as melt pressure and temperature, body temperature, main screw and feed screw for the entire extrusion process. The parameters such as the rotational speed, the feeding amount, the ratio of various raw materials, the current and voltage of the motor are detected online, and the closed-loop control of the microcomputer is adopted. Some companies have adopted online remote monitoring, diagnosis and control to network control the extrusion molding line. This is extremely advantageous for ensuring the stability of the process conditions and improving the accuracy of the product.

HDPE ROUND BALES NET WRAP is fast becoming an attractive alternative to twine for the wrapping of  round  hay bales. This soft white netting has the following advantages when compared to twine: Using of netting dramatically improves productivity because it takes less time to wrap a bale. You will be able to reduce time by more than 50 %. Netting helps you to make better and well - shaped bales which are easier to move and store.
Our net wrap is suitable for all crops (hay, straw, silage) under all weather conditions and enhances water shedding ability.
