Introduction of injection molding machine

Introduction of injection molding machine

What is an injection molding machine?   It is the thermoplastic or thermosetting material using plastic molding mold to make plastic products of various shapes of the main molding equipment. Divided into vertica l, horizontal, full electric. The injection molding machine heats the plastic and applies high pressure to the molten plastic, causing it to shoot out and fill the mold cavity. History of injection molding machine. The injection molding machine was invented in the United States in 1872 and has a history of 130 years, but the screw injection molding machine has been developed in the past 50 years and become the most commonly used injection molding machine in the industry today. At present in the engineering plastics industry, 80% of the use of injection molding. The

The general structure of injection molding machine

First, the structure of the injection molding machine Injection molding machine is usually composed of injection system, closing system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system and so on. 1. Injection system Injection system function: injection system is one of the most important parts of injection molding machine, generally have plunger type, screw type, screw preplastic plunger injection type 3 main forms. At present the most widely used screw type. Its function is that, in a cycle of the plastic injection machine, a certain amount of plastic can be heated in a specified time after plasticizing, under a certain pressure and speed, the molten plastic is injected into the mold cavity through the screw. After injection, the molten material injected

Classification of injection molding machines

Injection molding machine is the use of plastic molding mold thermosetting plastic or polyurethane elastomer into various shapes of plastic products and equipment. Another name is injection molding machine or injection molding machine. Many processing plants called die cutting machine, injection parts called beer parts. It is a key molding machine and equipment for making thermosetting plastics or thermosetting plastic materials into plastic products of various shapes using plastic molding molds. According to the classification method of injection molding machine and mold locking equipment, it can be divided into column, vertical and vertical. Injection molding machine   Classification of large injection molding machine: There are three types, depending on the type of mold locking element and injection element: horizontal, vertical, and angular. (1) Horizontal injection molding machine: Horizontal

Influencing factors of plastic injection molding process

1. Shrinkage rate Forms and calculations of thermoplastic molding shrinkage As mentioned above, the factors affecting thermoplastic molding shrinkage are as follows: 1.1 Thermoplastics In the molding process, due to the volume change from crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors, thermoplastics have a larger shrinkage rate, wide shrinkage range and obvious directivity compared with thermosetting plastics. In addition, the shrinkage rate after forming, annealing or humidification treatment is generally larger than thermosetting plastics. 1.2 Characteristics of plastic parts During molding, the molten material contacts the surface of the cavity and the outer layer is cooled immediately to form a low-density solid shell. Due to the poor thermal conductivity of plastic, the inner layer of plastic parts

Do you know how to reduce the power consumption of injection molding machine to improve its own work efficiency?

How to reduce the power consumption of injection molding machines to improve their own work efficiency?   Usually, injection molding machines will have the problem of high electricity consumption, and because of what reasons? For the traditional injection molding machine, how to expand the space of energy saving?       The energy consumption of the machine is mainly reflected in the following parts: (1) Electric energy consumption of hydraulic system oil pump; (2) The power consumption of the heater; (3) Power consumption of circulating cooling water pump. The power consumption of hydraulic oil pump accounts for more than 80% of the total power consumption of injection molding machine.                So, what are the energy-saving transformation methods of injection molding machine?

How to choose a chiller?

Home drinking water is a rigid and long-term development of the big market. Household drinking water can be divided into plain boiled water, water purifier filtered water and packaged water. At present, the sales volume of packaged water is only 15.5% of the total drinking water volume, and the development space is broad. The quality of tap water and long-term trends determine the home packaged water space. Through the comparative analysis of Chinese and American tap water systems, it is expected that it is difficult to further improve the overall quality of Chinese tap water terminal, ana lod the domestic drinking water market will remain prosperous for ng time. The water purifier market has entered a bottleneck period, while the 100 billion level barreled water market is still growing

How to Control the Injection Pressure of Injection Molding

All movements in the injection molding process, whether hydraulic or electric, generate injection pressure. Appropriate control of the required injection molding pressure produces a great product with good quality. The injection pressure regulation and metering system is on the hydraulic injection molding machine, and all movements are performed by the oil circuit responsible for the following operations: 1. Screw rotation in the plasticizing stage. 2. Slider feeder (the nozzle is close to the nozzle bushing). 3. Axial movement of the injection screw during injection and pressure holding. 4. Close the base material on the injection rod until the toggle rod is fully extended or the piston mold clamping stroke is completed. 5. Start the ejection table of the assembly ejector to eject the components. On full electric injection
