Advantages of Plastic Injection Molding

Injection molding is useful in making components of large products that we use today. 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.

The different kinds of materials that can be sued for injection molding are glass, metal, and thermoplastics. Below we will look at plastics and how this material is the best in terms of cost and recyclability.

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. There is a need to put additives so that the plastic will not be so brittle especially when exposed to very cold temperatures. 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. The process of injection molding has other benefits like the ones given below.

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. With this you get to save money on plastic, and you don’t have much waste as to worry about waste management.

Scrap plastic can still be used for other important parts and components. You can compare the quality of this waste plastic to virgin plastic. There is a great minimization of waste.

Injection molding labor cost is a lot lower than molding plastic by hand. There is high productivity with injection molding and it produces products at a much faster rate.

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. If the product is defaced then they are remade.

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. Plastic is used by industries like automotive, oil, gas, and electronics on a regular basis.
