Advantages of Plastic Injection Molding

Today, components of large products that we use today are made using a process called injection molding. 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. In the discussion below, we will look at plastics which is the best materials among others in terms of cost and recyclability.

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. 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. Plastic becomes brittle in very cold temperatures and this is why they put additives to prevent this. If you want to form other shapes from a finished product, you can just simply reheat it.

If you have to make plastic products by hand, what could be the result? We would be left with misshapen and structurally weak objects that wouldn’t last a day. 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. You save money with this and you will have less problem with waste management.

If you have waste plastic then they can be used to form other important parts and components. Scrap plastic and virgin plastic are of the same quality. 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.

If we speak of defects, plastic made with injection molding 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.

Though plastic is known to many as non-biodegradable, it is highly recyclable and plants can use discarded and unused plastic parts.

With injection molding there is a shorter finishing time because the process always takes care of most of the work. It reduces further the cost of labor and time.

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.
