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.
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 known for its durability, rust resistance, and toughness despite its being low in density. 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. Reheating the finished product will allow you to change the form of its shape.
Imagine a world where all plastic products have to be created by hand. We would be left with misshapen and structurally weak objects that wouldn’t last a day. 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.
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 benefit on money savings and lesser problems with 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. 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.
If we speak of defects, plastic made with injection molding have very little or no defects. Burrs, uneven layers, blisters, voids, and empty spaces on the surface are the common defects of this type of molded plastic. 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.
The injection molding process takes care of most of the work which makes the finishing time 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.
