The Leap Forward Development of Plastic Machinery Small Internal Mixer Industry

December 19, 2023

In the process of producing tube films, the traditional machine structures used for preparing melt, such as small internal mixers and screw extruders, have undergone fundamental changes (first of all, the geometric dimensions of the screws and the working surface of the barrel), using new filters, machine heads, thin film heat treatment, and traction devices. The improvement of the production process and equipment can increase the productivity of the production line by 0.5-1.0 times, and the difference in film thickness can be reduced by 50%.
In current machine manufacturing, the principle of combination is widely used in the construction of equipment, which means that each main mechanism in the process flow can independently complete the maximum possible function. This can not only improve the uniformity of equipment, but also timely and quickly modernize local production lines, and create favorable prerequisites for replacing outdated devices and mechanisms. For example, using a multi-stage screw with shear and mixing elements, as well as a barrel with inner grooves, can increase the productivity of the extruder by 0.5-1.0 times, while maintaining the necessary melt temperature and improving its uniformity (homogeneity).

Similarly, it also solves the modernization problems of the forming machine head, filter, traction device, and coiling device. In this case, equipment units such as motor drive with control system, heating automation system, outer cover and structural components (elevated, mixer, press machine base, etc.) are actually not changed.

Dongguan Zhenggong Electromechanical Equipment Technology Co., Ltd. was founded in 1988 in Dongguan, Guangdong. Its main products Small open mill, Small internal mixer, Small tablet press, small vulcanization machine, Small extruder, and various customized laboratory mixer rubber and plastic mechanical equipment. Established the Taiwan Joint Venture Business License in 2009, after more than 30 years of research and development and creation. It has been located in Houjie Town, Dongguan City, Chinese Mainland Province, mainland China.
