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. Below we will look at plastics and how this material is the best in terms of cost and recyclability.

The best and low cost alternative to metal, which is expensive, and glass, is plastic. 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. 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. These products can come out misshapen and structurally weak objects. With injection molding design precision is achieved, and structural soundness is maintained. 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. You can compare the quality of this waste plastic to virgin plastic. Therefore waste is minimized.

The cost of labor for using injection plastic is not as high the cost for molding plastic by hand. There is high productivity and the time taken to manufacture products is drastically cut down.

Injection molded plastics usually have very little or no defects. 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. They remake products that are defaced.

Despite its bad reputation as being non-biodegradable, plastics are highly recyclable and plants often use discarded and unused plastic parts.

Since almost everything in the work is done in the injection molding, then the finishing time is shorter. It reduces further the cost of labor and time.

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.
