Advantages of Plastic Injection Molding

Injection molding is useful in making components of large products that we use today. Ice trays, bottle caps, and bins are just some of the products that are made from injection molding which uses mold cavities where molten material is poured and solidified.

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. Plastic is durable, rust-free and very tough considering that it is low in density. 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. In order to reduce brittleness when plastic is exposed to very cold temperatures, additives are added. If you want to form other shapes from a finished product, you can just simply reheat it.

Imagine a world where all plastic products have to be created by hand. These products can come out misshapen and structurally weak objects. Injection molding ensures precision in design and soundness in structure. 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. With this you get to save money on plastic, and you don’t have much waste as to worry about 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. Sometimes there are defects in the resulting plastic product with the common defects being burrs, uneven layers, blisters, voids, and empty spaces on the surface. Defaced products are remade.

Despite its bad reputation as being non-biodegradable, plastics are highly recyclable and plants often 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.

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