Ever since engineering-grade plastics surfaced in the 1950s, several parts and components previously made from metal have been replaced with injection-molded plastic parts.
The primary reason for this transformation in the part manufacturing process is the reduced cost.
Most industries agree that by turning to plastic parts they save 20-50% of the total production costs. This is impressive, considering the fact that plastic also has some of the characteristics of a metal. It is durable, reliable, and can be molded into any shape. Despite this, many industries resist switching from metal to plastic.
But these reasons point out why they should convert to plastic parts by contacting a custom plastic parts manufacturer:
Plastic is flexible and offers better design. So, it makes sense why plastic molding engineers love the freedom offered by plastic molded parts.
Engineers and plastic injection molding product designers can test different plastic types during the designing phase, allowing for stronger performance outcomes and predictive design changes. Plus, they can mold plastic into complex shapes and geometries with ease using the latest technology and equipment to achieve their desired shape.
Plastic is also lightweight, which results in weight reduction and improved structural limit. Combine these design features, and you will have a durable, aesthetically pleasing, and lightweight part for your applications.
Compared to metal parts, plastic injection molding products are 50% lighter and offer performance characteristics that metal parts can’t. They weigh less and can be molded into reduced size and thickness, which is a considerable benefit for facilities with limited space.
Plastic molded products are also durable and reliable. So much so that today’s plastic parts are often compared with metal parts when it comes to withstanding a substantial amount of stress.
Unlike metal parts, modern plastic molded products do not rust and offer high resistance to impact and heat, which is impressive.
When it comes to manufacturing, plastic injection molding provides a faster and more consistent manufacturing process, including uniform production, decreased part defects, increased customer satisfaction, and reduced warranty claims. They also offer the flexibility of combining two different parts into one single part. This eliminates the need for welding, fasteners, and bolts, which is the case with metal-fabricated parts.
Plastic injection molded products don’t require coating or painting to keep corrosion or mold and mildew away. However, metal parts demand regular maintenance to be in good condition.
Even though industries relied on metal parts for centuries, they need to realize that now they have a better alternative to metal, which is not only reliable and durable but also cheaper than metal and performs its job pretty well. And that is engineering-grade plastic.
