What are the advantages of plastic injection molding? How does an injection molding machine work?
Plastic is an essential item for daily life, business, and various industries, such as household appliances, packaging, electrical appliances, toys, automotive components, medical equipment, agricultural tools, construction equipment, electronic equipment, etc. Many factories or companies therefore produce plastic to meet the large demand for plastic. There are many methods for shaping plastic, such as injection molding, blow molding, extrusion molding, and compression molding, with the most popular method being plastic injection. In this article, Idda Machine Tools Co., Ltd., the importer of plastic injection molding machines, will take you to learn about plastic injection and injection molding machines.
Plastic injection molding
Plastic injection molding is suitable for mass production of products, especially complete products such as bottle caps, food containers, automotive parts, office supplies, household items, toys, etc.
Advantages of plastic molding by plastic injection molding
- Manufacturers can design the parts to be formed in the desired way, both in appearance and shape.
- Suitable for producing finished products.
- Able to produce a large number of pieces in a short period of time (mass production)
- It is an automated process, resulting in savings in labor costs. The plastic injection molding process is almost entirely performed by machinery, with only minimal human intervention required for setup and control.
- Quality control is possible. The quality of the workpieces is consistent.
- Can be used to shape detailed or complex workpieces.
- There are few leftover parts.
The Injection Molding Machine is the most important tool in a plastic injection molding plant. Its function is to melt plastic pellets or powder into a liquid, which is then transported to a mold for injection molding to produce various plastic parts or products.
Main components of an injection molding machine
Plastic injection molding machine (Injection Molding Machine) consists of 3 important parts:
- The base supports the working process of the plastic injection machine.
- Clamping Unit
- Injection Unit This article focuses on the injection unit, which is the most essential part of the injection machine.
The injection unit’s key functions begin with drawing raw materials, which are plastic in pellet or powder form, into the injection cylinder and sending them through various processes. The plastic is then melted to the quantity required by the operator or factory before being pressed into the mold. The mold temperature is then lowered until the liquid plastic solidifies. The mold is then opened and the finished product is removed. The mold is then closed to prepare for the next injection.
Components of the plastic injection part in the plastic injection machine include:
- The hopper is a large cone-shaped container used to hold plastic pellets or powder, as well as other materials required for plastic molding, for feeding into the injection molding machine.
- The injector and screw are fixed cylinders, one side connected to the hopper and the other to the nozzle tip. The injector has a heater to control the temperature for the melt. Inside the cylinder, there is a coarse threaded screw that controls the movement of the plastic, increasing the pressure to make the molten plastic flow into the mold.
- The nozzle is the connection between the plastic barrel and the mold, transporting the molten plastic into the mold.
The drive motor allows the screw to move, injecting plastic into the mold. The motor can be either an electric or hydraulic motor. - The Hydraulic Clamp Unit, which may be called simply the clamp, has functions related to the mold, including opening and closing the mold cover, warming up the mold to prepare it for plastic injection, and then reducing the mold temperature to allow the workpiece to harden.
- The central control unit is used to control the operation of various devices in the plastic injection machine, such as controlling the power supply device, pressure control device, timer device, etc.
