Plastic injection molding machine is a specialized machine used in the injection molding technology line. Plastic injection molding machine adapts well to a variety of products and has a high production capacity. So, it is widely used in the production of plastic products.

So how is the structure of the plastic injection machine? What types of plastic injection molding machines are commonly used? Please read the information below.

Structure of horizontal plastic injection machine

The plastic injection molding machine composes of 2 components responsible for different jobs. The mold clamping part and the plastic injection part are important.

In addition, the mold clamp section divides into a fixed mold clamp part and a movable mold clamp part. In particular, the fixed mold clamp uses to hold the fixed mold part and the mold positions accurately. Thanks to the positioning ring on the mold and the positioning hole on the machine.

The movable mold clamp is used to clamp the movable mold half

This part has the effect of parallel translation in the opening and closing direction of the mold. It performs the closing and opening of the mold in the plastic injection molding machine.

The movable mold also arranges to help impact the battery ejection plate to push the product out.

Moreover, the plastic injection part is the part used to convert the material from solid to liquid by temperature. It pushes the molten plastic into the mold by pushing pressure through the screw and nozzle system.

In addition to the two main parts above, the plastic injection machine structure also has a cooling system (making the machine).

Popular types of plastic injection molding machine

There are many ways to classify plastic injection machines. Based on the structure of plastic injection machine divided into types:

Horizontal injection molding machine

This injection molding machine is the most common type, characterized by the mold part and the nozzles located on the center axis horizontally. The mold opens in the horizontal direction. Moreover, horizontal plastic injection molding machine takes up a lot of space in width.

Vertical presses

In addition, in principle of operation, horizontal presses and vertical presses are the same, but they differ in the layout of components and details. The vertical press has the mold unit and the nozzle located on the center axis vertically, and the mold opens in the vertical direction. Plastic injection molding machine takes up a lot of space in height.

Inclined injection molding machine

The structure of the inclined injection molding machine consists of the mold and the nozzles that are not located on the central axis, but form an eccentric angle. Moreover, plastic injection direction and interface are on the same mold surface.

Rotary injection molding machine

In addition, special structure consisting of many molds characterize by rotating clamping structure. The molds arrange around the rotating shaft.

In factories and enterprises producing plastic products in our country, most of them use two types of plastic injection machines: horizontal and vertical presses.

The benefits of using a plastic injection molding machine

Moreover, using plastic injection molding machine brings outstanding advantages:

  • Plastic injection machine is capable of molding hard plastic, flexible plastic, thermosetting plastic, …
  • It has automatic plastic injection cycle, high working productivity, saving time and labor
  • Plastic injection products meet quality standards, are accurate in size, design and have high aesthetics.
  • Lower production costs compared to other plastic production methods.

Professional plastic processing

The rapid development of the plastic industry requires manufacturing enterprises to equip modern plastic injection molding machine to enhance the quality of plastic injection processing.

In addition, injection molding is the process of using machinery and equipment to inject molten plastic into a network of forming systems called molds. Moreover, after the plastic changes from the liquid state to the solid state, we open the mold and get the product in the desired shape.

What is plastic injection mold?

Plastic injection mold is a homogenous system made up of many components for the purpose of shaping the molten plastic into the desired product after hardening.

What is the injection molding cycle?

The injection molding cycle is the process that starts from the moment the molten plastic puts into the mold cavity through the channel system in the plastic injection molding machine. Moreover, it solidifies the plastic by cooling solutions so that the mold completely opens.

Finally, the process ends with closing the mold to start repeating the process.

Plastic injection mold construction

Plastic injection mold is divided into 2 parts;

Fixed part (Male); this part is the part that does not move during the whole injection molding process. This part fastens to the wall of the machine to fix the plastic injection molding machine and connects to the plastic injection nozzle system of the plastic injection molding machine to bring the molten plastic into the mold cavity through the nozzle and channel system.

Movable part (Male mold); This part is the part that has the function of closing the mold to press the product and opening the mold to get the product.

Moreover, the movable part will fasten to the wall of the mobile machine of the injection molding machine and connects to the mold liner system to push the product out through the push pin system designed in the mold.

Injection molding aims to reshape a raw material

Plastic: As it is a super versatile process, it also allows the reuse of recyclable raw materials, thus giving the material a new destination.

There are different types of plastic injection molding machine to create plastic design parts, including some methods do together to create a single product. An example of this is the manufacture of bottles. While the bottle body made by blow molding.

Moreover, the cap made by injection molding, while the thread at the top of the neck comes from a process called injection and blow molding.

Each of these manufacturing processes is capable of creating a certain pattern and making products of the highest quality.

The main types of molding are:

  • insert molding,
  • thermoplastic,
  • over molding,
  • cold chamber molding,
  • hot runner molding,
  • 3D printing.

When polymers go through the molding process in plastic injection molding machine, they become molded parts. It is a real modification in the structure of the plastic, which passes through cylinders and mixers until it becomes a homogeneous mass.
