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. The process uses mold cavities into which materials in molten state are poured and solidified to from useful things like ice trays, bottle caps, bins, and other things.

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.

The best and low cost alternative to metal, which is expensive, and glass, is plastic. Plastic is known for its durability, rust resistance, and toughness despite its being low in density. In particular, thermoplastic allows manufacturers to produce very complex shapes at a much lower cost than other materials. Because it is pliable it can take on any shape and when it is cooled, the shape hardens. Plastic becomes brittle in very cold temperatures and this is why they put additives to prevent this. Reheating the finished product will allow you to change the form of its shape.

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. Below are some of the other benefits of injection molding.

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.

Other parts and components can be made from waste plastic. Scrap plastic and virgin plastic are of the same quality. Waste is minimized or almost eliminated.

The cost of labor for using injection plastic is not as high the cost for 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.

Since almost everything in the work is done in the injection molding, then the finishing time is shorter. Labor cost and time is further reduced.

The only solution where metal and glass cannot be used in certain applications is the use of plastic injection molded products. Plastic is used by industries like automotive, oil, gas, and electronics on a regular basis.
