Here's Why Most Industries Prefer Metal Parts to Plastic Parts
Plastic parts are being used more in industries because they are cheaper to produce at a large scale and are high quality. Plastic is very versatile, and can be molded into various shapes and forms. It is continuously being re-engineered to make it lighter and efficient for various uses.
Plastic Injection Molding
Plastic injection molding is the most commonly used method in the mass manufacturing process of plastic. It requires the use of an injection molding machine whereby the plastic is melted in the machine and then put into a mold where it solidifies with time.
Plastic Parts Vs. Metal Parts
Various industries require plastic parts for manufacturing, for example; Automobile, Construction, Textiles, Medical, Aerospace, and Food & Beverage, and they prefer plastic parts over metal parts because of the following reasons:

- Plastic is lighter than metal and cheaper to use in manufacturing because the denser the material, the more the installation and logistics costs.
- The use of plastics is also less labor-intensive and does not take up a lot of production time, therefore saving on time and energy costs.
- Due to various additions to plastic formulations like carbon fiber and glass fiber, the plastic part's strength to weight ratio is just as good as metal. Their strength to stiffness ratio is higher than most metals meaning that plastic parts are durable and not likely to deform.
- Metal is harder to work with and shape as compared to plastic. Thermoplastics allow flexibility in design options as compared to manufacturing parts using metal.
