What is Plastic Injection Molding?

Plastic injection, one of the plastic molding methods, is widely used in the modern manufacturing industry. With the plastic injection method, thermoplastic and thermoset plastic granules are melted and poured into the injection mold under high temperature and pressure. The plastic that cools in this mold takes the shape of the mold and plastic products of the desired design and size are obtained.

Plastic injection molding is used to produce parts in many sectors from automotive to toy industry. Plastic injection molding is very advantageous given its high productivity, suitability for reuse and easy production of complex parts. In this article, we will examine how plastic injection molding is done, what is the production process, what are its advantages and where it is used.

What is a Plastic Injection Molding Machine, What does it do?

What Is Plastic Injection Molding Like?

Plastic injection molding is a production process in which plastic materials are melted and shaped by injecting them into molds. Below you can examine the plastic injection molding production process in 5 steps.

1. Material Preparation: The plastic material to be used for plastic injection is determined and prepared. The plastic in granule form is melted by the injection molding machine.
2. Mold Design and Preparation: The mold is prepared according to the design of the plastic material to be produced. The cavities and details in the mold determine the shape of the injected plastic material.
3. Injection: Granulated plastic is put into the injection machine and the plastic is melted. The melted plastic material is injected into plastic molds with an injection pump.
4. Cooling: The injected plastic material is allowed to cool in the mold. At this point, the plastic part takes shape and forms its form.
5. Demolding: The cooled plastic part is removed from the mold. Depending on the area of use of the part, additional processes such as part cutting and cleaning are performed if necessary.

This is the answer to the question of how plastic injection molding works. In 5 steps, we have shared the plastic injection production process with you. Now let’s examine where plastic injection is used.

Plastic Injection Molds in Plastic Production Process

Plastic injection molds are the name given to the molds used in the plastic injection production process. With these molds, the shape of the plastic material to be produced is given. The melted plastic is poured into the injection molds and the actual design of the part to be produced emerges. The cavities and details in the mold determine the shape of the actual material.

With the right plastic injection mold, the cost of production is reduced and a highly efficient mass production is made. The most important step in the plastic injection production process is to design these molds accurately, precisely and millimetrically.

What Does Plastic Injection Molding Do and What Are Its Benefits?

Plastic injection molding is a production method in which plastic granules are melted and shaped by injecting them into injection molds. Here are the benefits of plastic injection molding;

1. Mass Production: It is one of the most efficient methods for mass and fast production. Many plastic parts are produced at the same time and the production process progresses quickly.
2. High Precision: The plastic injection molding process requires high precision. The plastic material injected into the molds is shaped according to the mold details and error-free parts are produced in accordance with the desired tolerances.
3. Various Design Options: The plastic injection molding method offers unlimited design options. Molds are designed specifically for the part to be produced and plastic parts in different geometric shapes are produced.
4. Low Cost: It is a lower cost production method compared to other production methods. High quantities of plastic parts can be produced at low costs in mass production.
5. Material Diversity: Different plastics can be processed with plastic injection molding. In this way, while plastic parts with different properties are produced, parts are also provided to many industries.

Considering all these reasons, plastic injection molding is a widely used production method in many industries. Now let’s see where plastic injection is used.

In which sectors is plastic injection used?

Plastic injection molds are widely used in many sectors where parts are produced. These sectors are as follows:

1. Automotive Industry: Plastic injection molding is frequently used for the interior and exterior parts of automobiles. For example, car bodies, seat parts, interior trim parts and headlights are produced with plastic injection molds.
2. Electronics Industry: Electronic devices are devices where plastic parts are used extensively. Case parts, connectors, buttons and covers are produced with plastic injection molds.
3. Medical Industry: Medical devices and equipment need sterile and durable plastic parts. Plastic injection molds play an important role in the production of parts used in the medical industry.
4. Packaging Industry: Plastic injection molds are used especially for food and beverage packaging. The most commonly produced products include bottles, closures, packaging boxes and bags.
5. Home Appliance Industry: Manufacturers of home appliances and white goods use plastic injection molds in their products. For example, products such as refrigerators, washing machines, ovens and microwave ovens contain plastic parts and are produced with plastic injection molds.
