The main purpose of "Injection Technology and Injection Molding Machine" published by Chemical Industry Press is to make readers fully understand the structure and performance of injection molding machine, master the use method of injection molding machine and solve practical problems encountered in production. The book mainly introduces the injection principle of the injection molding machine, the structure of each part of the injection molding machine, the working principle of each system that constitutes the injection molding machine, installation, adjustment, use and maintenance. As a link closely related to injection molding machine, this book also introduces the basic technology of injection molding, the properties of raw materials, technological conditions and the basic knowledge of injection mold. This book can be used as a vocational training material.

The readers of this book are mainly the technicians and sales staff of manufacturers and scientific research units that produce and use injection molding machines. It is also suitable for teachers and students of colleges and universities in related industries to read. Based on more than ten years' maintenance experience and teaching experience of injection molding machines, the author systematically introduces the structure, principle and maintenance methods of mechanical transmission system, hydraulic transmission system and electrical control system of injection molding machines, and the adjustment methods of common injection molding machines, taking Zhenxiong, Haitian, Lijin, Zhende, Tejia and Heidelberg as examples. Compared with similar books, it has the following characteristics:

1. Explain thoroughly, easy to learn and understand. For example, when explaining the electronic control circuit of injection molding machine, the author divides the electronic circuit into independent circuit units such as proportional pressure and proportional flow electronic amplifier circuit, ordinary switch I/O interface circuit, dialing circuit and power supply circuit, and introduces the functions of main components in the circuit units, the detection methods and replacement standards of vulnerable components in detail. In addition, in order to let beginners and readers with poor foundation understand the whole book of injection molding machine maintenance, the author has set up another chapter to explain the basic knowledge of electronic circuit and oil circuit of injection molding machine maintenance respectively.

2. Pay attention to maintenance details, which is practical. For example, when explaining the mechanical structure of injection molding machine, the author focuses on the disassembly steps, assembly requirements and testing methods of mechanical parts, and is equipped with a large number of local enlarged drawings. When explaining the electrical circuit, the function of main components, the detection method and replacement standard of vulnerable components, and the judgment standard of whether the parts are damaged are emphatically introduced.

3. The system is comprehensive. This paper introduces the mechanical transmission, oil circuit and circuit of injection molding machine, analyzes the common faults of various mainstream models and their treatment methods, and collects the main circuit diagrams of various mainstream models for readers' reference.

Therefore, it can be used as a textbook or training material for beginners, and can also be used as a reference book for injection molding machine maintenance practitioners.
