Advantages of Plastic Injection Molding

Today, components of large products that we use today are made using a process called injection molding. 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. If we consider cost and recyclability, plastics rule over the other materials, and this will be discussed below.

The best and low cost alternative to metal, which is expensive, and glass, is plastic. Durable, rust-free and very tough despite its density, are the characteristics of plastic that makes it superior to others. If you use thermoplastic, it is possible to produce complex shapes at a much lower cost than any other material. Because it is pliable it can take on any shape and when it is cooled, the shape hardens. 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.

If you have to make plastic products by hand, what could be the result? We will have products with bad shapes and are structurally weak. Injection molding ensures precision in design and soundness in structure. Below are some of the other benefits of injection molding.

Since the molding cavities can only contain the amount of plastic that is needed, it minimizes or eliminates scraps. With this you get to save money on plastic, and you don’t have much waste as to worry about waste management.

If you have waste plastic then they can be used to form other important parts and components. The quality of this waste plastic is the same as with 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.

There are little or no defects with injection molded plastics. Burrs, uneven layers, blisters, voids, and empty spaces on the surface are the common defects of this type of molded plastic. 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. It reduces further the cost of labor and time.

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