Guide to Plastic injection Molding and Its Benefits

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. In the discussion below, we will look at plastics which is the best materials among others in terms of cost and recyclability.

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. Taking on any shape is possible with thermoplastic because it is pliable and it hardens upon cooling. There is a need to put additives so that the plastic will not be so brittle especially when exposed to very cold temperatures. Reheating the finished product will allow you to change the form of its shape.

Imagine if all plastic products in the world were handmade. We will have products with bad shapes and are structurally weak. With injection molding design precision is achieved, and structural soundness is maintained. Here are some of the advantages of this invaluable process.

If molds are used the amount of scrap is reduced or eliminated because the cavities are shaped to contain only the amount of plastic that is needed. You save money with this and you will have less problem with waste management.

Other parts and components can be made from waste plastic. You can compare the quality of this waste plastic to virgin plastic. Waste is minimized or almost eliminated.

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.

There are little or no defects with injection molded plastics. Burrs, uneven layers, blisters, voids, and empty spaces on the surface are the common defects of this type of molded plastic. If the product is defaced then they 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.

The injection molding process takes care of most of the work which makes the finishing time shorter. Labor cost and time is further reduced.

If metal and glass cannot be used in certain applications they use molded plastic products. Plastic is used by industries like automotive, oil, gas, and electronics on a regular basis.
