Since the introduction of engineering-grade resins and Plastic Injection Parts in the 1950s, many parts previously made of metal have been replaced by injection molded parts. On average, companies report overall savings of 25-50% by converting to plastic parts, but some manufacturers have refused to make changes.

When product manufacturers do not consider using plastic instead of metal, it is likely because they do not understand the complex qualities that plastic can provide. Others simply appreciate the predictability of using the same materials used in the initial design of the part, rather than considering plastic materials that will match or exceed the performance properties of current materials.

As a production material, plastic blends can be customized to meet specific environmental, structural, and operational requirements. Proper design and material selection can produce plastic parts that are superior to metals. In addition, the addition of stiffeners (such as ribs and gussets) that can be molded directly into plastic will increase strength and durability and reduce production time.

When additives are mixed directly into plastic, they can enhance specific properties and create highly customized materials. These additives improve plastic properties in areas such as impact and tensile strength, friction, scratch resistance and flame resistance. Additives make plastic lighter, safer, can be used in food distribution and medical supplies, and are more environmentally friendly.

Whether you are currently considering a transition or the uncertainty of the metal market is looking for viable options, there are many advantages to converting metal parts to plastic.
