5 Benefits of Using Plastic Injection Molding

Plastic injection molding is a highly flexible option to manufacture a wide range of parts. It is appreciated for a variety of reasons, such as its extreme efficiency, great reliability, option to reuse and its ease of use. Let’s take a look at a few of the benefits of using plastic injection molding:

Complex designs

The plastic is subject to high pressure, which is very effective at creating the unique and complex designs. The extra pressure helps to simplify the process of introducing fine detail to any part, as well as making it possible to create the most intricate and complex shapes. Other molding processes that don’t rely on high pressure to mold parts will have a lot of difficulty in creating the most precise parts.

Fast production

Once the initial injection molding is created, the process to make the individual parts is very fast and effective. The fast production means it is one of the most efficient and cost-effective methods for creating the plastic parts. Also, the option to use a single mold means it is easier to produce a lot more parts than other manufacturing methods.

Improved strength

This molding process makes it very easy to inject special types of fillings into the plastic to increase the all-round strength. The extra filler will lower the plastic density at the time of manufacturing, but is very helpful for improving the strength of the item of plastic being molded. This is certain to benefit in industries where it is necessary to have the very strong and durable parts. Also, this is a feature that isn’t offered by offer molding methods.

Using multiple plastic types

The flexible manufacturing process gives the option to use multiple plastic types simultaneously throughout the manufacturing process. This process is called co-injection molding. It is a further option to improve strength and helps to minimize any differences that may be present in the particular type of plastic.

Automated manufacturing

The automated nature of plastic injection molding helps to cut down on manufacturing costs. Once the mold is designed and created, the actual manufacturing process is completed by robotics and machines. However, there is a single operator to manage and control the process. An automated system is very effective at cutting costs. A major reduction relates to the small workforce to operate the machinery. Also, the automation of the mold production using computer aided manufacturing (CAM) or computer aided design (CAD) increases the ability to create the accurate molds.
