5 Major Advantages of Plastic Injection Molding

As far as versatility is concerned, plastic injection molding is one of the best production methods. The reason is that it offers a lot of advantages over other traditional methods of injection molding. This method is simple, reliable and more efficient. That’s the reason most manufacturers use it to make parts. In this article, we are going to discuss the 5 primary advantages of using plastic molding.

1. Complex Geometry and Detailed Features

We know that molding involves extremely high pressure. So, this high pressure allows manufacturers to add a lot of details to the components. Aside from this, the extreme pressure helps make complex shapes. Other methods can also help achieve the purpose but the cost and complications will be too high.

2. High Efficiency

After the designing of the molds, the molding process becomes quite quick, unlike other molding methods. Actually, plastic injection molding doesn’t take much time. Moreover, it allows the making of a lot more parts in a short period of time.

That’s the reason this method is a lot more efficient. Usually, these parts are more consistent as far as quality is concerned. However, it won’t be easy to make changes to the colors.

3. Enhanced Strength

As far as plastic injection molding is concerned, fillers can also be added. They can cut down on the plastic density during the molding process. Plus, they can help add more strength to the components. Plastic molding can help make parts that can meet the strength needs of a specific application.

As a matter of fact, enhanced strength is one of the main advantages of this process that appeals to most manufacturers.

4. The use of Multiple Types of Plastic

Another main advantage of this technique is that it allows the use of the different types of plastic at the same time. And one way of doing so is to use co-injection molding. So, manufacturers are not limited to only certain types of plastic anymore.

5. Automation for Cost-Reduction

Since this process is automatic, it’s possible to save a lot of money. Most of the process is done by robotics and machines. These machines are controlled by only one operator. As a result, the cost of manufacturing comes down significantly.

Apart from this, the overall manufacturing cost comes down. So, the price tag is also lower, which makes it possible for even an average buyer to place their order. Automation also allows for accurate and precise injection molds. Both CAM and CAD enable close tolerance while the molds are made.

The Bottom Line

To cut a long story short, plastic injection molding helps make parts that don’t require a lot of post-production work. In fact, parts are complete from all aspects once they have been taken out of the molds.

Nowadays, this process is quite common as it’s eco-friendly. The scrap plastic is collected for reuse. Therefore, there is almost no waste left behind. So, this was a description of some of the most common advantages of plastic injection molding.
