Advantages of Plastic Injection Molding

Today, components of large products that we use today are made using a process called injection molding. How these products are done is through the use of mold cavities where molten materials are poured and solidified, and some examples of these products are ice trays, bottle caps, and bins.

Glass, metals and thermoplastics are the materials that can be used for injection molding. If we consider cost and recyclability, plastics rule over the other materials, and this will be discussed below.

Plastic is a low cost alternative to expensive metal and glass. Durable, rust-free and very tough despite its density, are the characteristics of plastic that makes it superior to others. In particular, thermoplastic allows manufacturers to produce very complex shapes at a much lower cost than other materials. Its pliability allows it to take o almost any shape but hardens when cooled. Plastic becomes brittle in very cold temperatures and this is why they put additives to prevent this. And when a product is finished, you can reheat it to form other shapes.

Imagine a world where all plastic products have to be created by hand. We will have products with bad shapes and are structurally weak. Injection molding helps to achieve design precision and maintain structural soundness. The process of injection molding has other benefits like the ones given below.

Minimizing or eliminating scrap is one of the benefits of using injection molding because the cavities can only contain the amount of plastic that is needed. You save money with this and you will have less problem with waste management.

If you have waste plastic then they can be used to form other important parts and components. Scrap plastic and virgin plastic are of the same quality. Therefore waste is minimized.

Injection molding labor cost is a lot lower than molding plastic by hand. Productivity is high with injection molding and it is faster to manufacture products.

If we speak of defects, plastic made with injection molding have very little or no defects. The common defects for this type of molded plastic includes burrs, an uneven layer, blisters when raised bits produce a rough and uneven surface, voids, empty spaces on the surface. Defaced products are remade.

People think of plastic as bad because it is non-biodegradable but it is highly recyclable like plants can use discarded and unused plastic parts.

With injection molding there is a shorter finishing time because the process always takes care of most of the work. The cost of labor and time is reduced further.

Molded plastic products are often the only solution where metal and glass cannot be used. Industries like automotive, oil, gas, and electronics use plastic on a regular basis.
