The injection molding machine has the ability to mold plastic products with complex appearance with metal inserts at one time. It is widely used in various fields such as national defense, automobile, transportation, building materials, packaging, agriculture, education and health. Today, let’s know more about injection molding machine.

The Main Types of Injection Molding Machine

According to the purpose of injection molding machine, it can be divided into many types, for example, injection molding machine for disposable spoon, injection molding machine for disposable knifeand so on. But according to the appearance, the injection molding machine can be divided into horizontal injection molding machine, vertical injection molding machine, angle injection molding machine and multi-mode turntable injection molding machine.

Horizontal injection molding machine:

This is the most common type. The clamping part and the injection part are on the same horizontal center line, and the mold is opened in the horizontal direction. Its characteristics are: short body, low center of gravity of the machine, stable installation; it is easy to realize fully automatic operation. At present, most of the injection molding machines on the market adopt this type.

Vertical injection molding machine:

Its clamping part and injection part are on the same vertical center line, and the mold is opened in the vertical direction. Therefore, its footprint is small. But the product is not easy to fall down automatically and must be removed by hand. Vertical injection molding machines are suitable for small injection molding machines.

Angle injection molding machine:

Its injection direction and mold interface are on the same surface, it is especially suitable for flat products. It covers an area smaller than a horizontal injection molding machine. This type of injection molding machine is suitable for small machines.

Multi-mode turntable injection molding machine:

It is a special injection molding machine with multi-station operation. Its characteristic is that the mold clamping device adopts a turntable structure, and the mold rotates around the shaft. This type of injection molding machine is particularly suitable for the production of large quantities of plastic products with a long cooling and setting time. However, due to the huge clamping system, this type of injection molding machine is widely used in plastic cups and other plastic products.

The Working Principle of Injection Molding Machine

The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw to inject the plasticized and molten plastic into the closed mold cavity, and obtain the product after solidification and shaping.

Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding-melting and plasticizing-pressure injection-mold filling and cooling-mold opening and picking. After taking out the plastic part, the mold is closed again for the next cycle.

Steps of using injection molding machine:

Step1: Understand the relevant information of the mold: it is best to obtain the design drawing of the mold and analyze it in detail

Step2: According to the different raw materials, do a moderate baking of the raw materials used.

Step3: Try to use the same raw materials as much as possible for mass production in the future.

Step4: Do not try the mold completely with inferior materials. If you have color requirements, you can arrange the color test together.

Nowadays, the injection molding machine is becoming more and more important in the injection molding production process. The development of automatic control technology has made the injection molding machine to be intelligent. Many industries are changing from labor-intensive to technology-intensive, and a large number of automated equipment is being produced. The use of injection molding machines can solve many problems such as high mobility of workers, short delivery times, and safety issues.

With the rapid development of the plastics industry today, injection molding machines occupies an important position in terms of quantity and variety.
