The Reasons to Use Plastic Injection Molding

Plastic injection molding is extremely versatile method of producing parts and products. It is one of the preferred methods for manufacturing parts because it has multiple advantages over other methods of plastic molding. Not only is plastic injection molding simpler and more reliable, it is also extremely efficient. You should have no doubts about using this method to manufacture parts.

In this article, we identify 5 specific reasons to use plastic injection molding for your parts manufacturing needs.

MPP Corp. is a leading plastic injection molding manufacturer specializing in production and prototype molds.

Reason #1: Plastic Injection Molding is Cost Effective

Furthermore, with reduced labor force the overall cost of manufacturing the parts is reduced and this cost saving can easily be passed on to the customer. Focusing on Design for Manufacturability (DFM) and other detailed processes during the design phase significantly reduces the number of problems sometimes encountered with moldability, minimizing the need for expensive tooling changes, downtime, and other production delays.

Plastic injection molding is an automated process. A majority of the injection molding process is performed by machines and robotics which a sole operator can control and manage. Automation helps to reduce manufacturing costs, as the overheads are significantly reduced.

Reason #2: Plastic Injection Molding is Versatile

Injection molding can handle extremely complex parts. complex and intricate shapes can easily be designed and manufactured which otherwise would have been too complicated and expensive to manufacture. The strength and durability of plastics has greatly increased over the years, and today’s lightweight thermoplastics can withstand even the harshest environments on par with — or better than — metal parts. Injection molding gives you freedom in design choices, especially when compared to metal.

Reason #3: Plastic Injection Molding is Efficient

Once the injection molds have been designed to the customer’s specifications and the presses pre-programmed, the actual molding process is very quick compared to other methods of molding. Plastic injection molding allows more parts to be manufactured from a single mold.

Reason #4: Plastic Injection Molding is Customizable

The advances in polymers over the years have contributed to the development of a large selection of resins from which to choose. Plastics can be colored using various coloring systems, each of which offers its own unique properties.

Reason #5: Plastic Injection Molding is Repeatable, Predictable and Consistent

High-output production of complex plastic parts requires a consistent, repeatable process to achieve designs with tight tolerances. Injection molding helps ensure a consistent quality by repeatedly using the same mold for each part, backed by an injection molder’s continuous improvement practices that incorporate current leading-edge technologies.
