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.

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.

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. 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. In order to reduce brittleness when plastic is exposed to very cold temperatures, additives are added. Reheating the finished product will allow you to change the form of its shape.

Imagine if all plastic products in the world were handmade. These products can come out misshapen and structurally weak objects. Injection molding ensures precision in design and soundness in structure. The process of injection molding has other benefits like the ones given below.

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. You can compare the quality of this waste plastic to virgin plastic. Waste is minimized or almost eliminated.

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. The common defects for this type of molded plastic includes burrs, an uneven layer, blisters when raised bits produce a rough and uneven surface, voids, 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.

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

If metal and glass cannot be used in certain applications they use molded plastic products. Industries like automotive, oil, gas, and electronics use plastic on a regular basis.
