Advantages of Plastic Injection Molding

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.

The different kinds of materials that can be sued for injection molding are glass, metal, and thermoplastics. If we consider cost and recyclability, plastics rule over the other materials, and this will be discussed below.

As we know plastic is the low cost alternative to expensive metal and glass. Plastic is known for its durability, rust resistance, and toughness despite its being low in density. Producing complex shapes at a much lower cost than other materials is possible with thermoplastic. Taking on any shape is possible with thermoplastic because it is pliable and it hardens upon cooling. 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 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. Below are some of the other benefits of injection molding.

Since the molding cavities can only contain the amount of plastic that is needed, it minimizes or eliminates scraps. You save money with this and you will have less problem with waste management.

Scrap plastic can still be used for other important parts and components. The quality of this waste plastic is the same as with virgin plastic. Therefore waste is minimized.

Injection molding labor cost is a lot lower than molding plastic by hand. There is high productivity and the time taken to manufacture products is drastically cut down.

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. They remake products that are defaced.

Though plastic is known to many as non-biodegradable, it is highly recyclable and 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. It is on a regular basis that plastics are used in industries like automotive, oil, gas, and electronics.
