Have you ever wondered why plastic products come in a variety of forms? The reason why is technology. Like in other industries, advancement in technology enables manufacturers to attain much in their line of production. This article focuses on addressing some of the techniques involved in this industry; structural foam moulding and plastic injection moulding.

Quick Overview of these Techniques

Although there are more techniques employed in the industry, we'll focus on only two. With structural foam moulding, you will get products with thicker walls that are distortion-free. On the other hand, plastic injection moulding gives strong and durable products. Here's an in-depth look at these techniques in specificity.

Structural Foam Moulding

Structural foam moulding entails blowing a chemical agent into plastic granules and activating it when heated to a melting point.

The foam injected, keeps on enlarging as long as the synthetic has not solidified. As a result, there is an equal distribution of force inside the product. This results in less tension on the end product.

Benefits of Structural Foam Moulding

  1. It lowers the risk of malformation
  2. It provides an option of having thicker walls
  3. One can further opt for walls with varying thickness
  4. Freedom of choosing your design

Plastic Injection Moulding

Plastic injection moulding works for various plastic products and varying components as well as residence or shaped items.

This technique involves the use of immense pressure to inject molten plastic granules into a production mould. When it cools down, the manufacturers remove the plastic which assumes the shape of the mould.

Below are some benefits of synthetic injection moulding

1. Detailed Features with Complex Shapes

You can also add many details to a design due to the extensive high pressure used in this technique. It is also possible to design and produce complex shapes because of this process's high pressure.

2. Efficiency

The moment they design injection moulds per the client's requirements, the preparation of the press starts, the entire process is fast. From a simple mold, they can manufacture several parts. Since the production flow is high, this method is more productive and cost-friendly.

3. Improved Product Strength

Using this technique, one can incorporate fillers in the injection mold. With the filler, you lower the parts' density while increasing their strength after the moulding process. When in need of a firm and long-lasting part, this might be a good option.

4. Use of Various Plastics at Once

With the use of co-injection, you can use varying plastics together.

5. Automated Manufacturing

To a great extent, machines help with synthetic injection moulding. As a result, a company saves on labor costs hence cheaper production costs. Customers can benefit directly from this. The automation further ensures that it makes accurate and precise moulds.

Which Method Works Best?

A quick look at the benefits of each of the methods discussed will enable you to identify a preference. However, to a large extent, it all depends on what you want to achieve. Different companies use these technologies. You only need to evaluate them to identify who to work with.
