1. A brief introduction to the history and current situation of the injection molding machine.

More than 50 years ago, the first injection molding machine, a screw-type plastic injection molding machine, came out. The first injection molding machine was mainly a small and medium injection machine with a clamping force of 1,000 to 5,000 kN and an injection volume of 50 to 2 kg. In the 1970s and 1980s, the injection molding machine industry advanced rapidly, and a large number of large injection molding machines were put into production. Looking at the current situation of the injection molding machine industry, the penetration rate of injection molding machines in the plastic machinery industry has reached more than eighty to ninety percent, and the output and sales of injection molding machines are being refurbished every year.

Chinese injection molding machines have been produced since the 1960s, and have continuously introduced foreign advanced technology and production management experience. Chinese injection molding machines are of high quality and low price, with a wide variety of products, and have received extensive attention and praise in the international and domestic markets. Ningbo in Zhejiang, Dongguan in Guangdong, and Zhongshan have become world-renowned injection molding machine production and processing bases.

2. What is the use of the vertical injection molding machine?

Zhongyang injection molding machine is mainly used in the processing and molding of thermoplastic plastics. Injection molding machines are widely used in the production and manufacturing of medicine, food, construction, automobiles, household appliances, national defense, packaging, agriculture, culture, education and hygiene.

Three, the structure of the injection molding machine

General injection molding machine is divided into four parts; hydraulic system, injection device, clamping device, electrical control system

Fourth, the operation points of vertical injection molding machine

1. The nozzle advances to the corresponding position → injects the plastic material into the barrel → maintains pressure.

2. Raw material shaping→reverse shrinking to consolidate the whole shape→nozzle retreat→cooling→forming→mould opening→ejection→closing.

A warm reminder from Zhongyang Machinery Editor: To be proficient in operating an injection molding machine, you must master certain related knowledge and operating techniques, such as electrical control cabinet operating techniques and hydraulic system operating knowledge. It is also necessary to master certain physics knowledge, such as pressure, speed, current, and voltage will be involved in the operation of the injection molding machine.

5. Prospects for the development of injection molding machines

Nowadays, there are more and more domestic manufacturers of R&D and production of injection molding machines, and the types of injection molding machines have changed from a single form to diversification. As environmental pollution intensifies, the concept of sustainable development has become more and more popular, and new energy-saving and environmentally friendly injection molding machines continue to emerge. Chinese injection molding machines are in the transition stage from low-end products to mid-to-high-end products in the international market. Therefore, in this In the critical period, all injection molding machine manufacturers cannot relax. Only by constantly mastering advanced technology, carrying out product reform and innovation, and strengthening the management of the enterprise, is the kingly way of the long-term development of the enterprise.
