Injection molding is one of the most widely used processes in today’s plastics manufacturing industry. And with good reason: injection molding services are fast, flexible, and cost-effective for many diverse projects. The process also accommodates a high degree of customization and complexity in product design.

Still, it's important to point out that the initial tooling costs can be high – and the more complex the mold, the higher your tooling costs. That means it’s a generally more suitable process for large-scale manufacturing. However, there are some specialized low-volume/prototype molding processes we can employ to make it economical for smaller runs as well. And besides – the benefits of our injection molding services in terms of efficiency, precision, quality, and repeatability outweigh the initial setup costs for many diverse product applications.

Below, we give a rundown on the main benefits that injection molding offers when it comes to manufacturing custom, potentially complex plastic products.

The Main Advantages of Plastic Injection Molding vs. Competing Production Processes:

A High-Speed, High-Capacity Manufacturing Solution

Injection molding is a relatively high-speed production process. For high-volume runs, it’s often the most efficient and cost-effective way to produce large quantities of parts in a short amount of time. To put it into perspective, the typical cycle time for each injection molding cycle is usually measured in seconds.

Rapid Injection Molding (RIM) for Quick Turnaround

For your low-volume projects, the speed of the injection molding process equals shorter lead times and the quickest turnaround possible. It also means the potential to more easily scale up to higher capacity in the future. This is especially beneficial to prototyping projects which will later grow into full-scale production.

Rapid injection molding (RIM) is one of the most effective ways to achieve rapid turnaround after the tooling is built – ideal for on-demand products and just-in-time manufacturing.

Design Flexibility and Material Versatility

Injection molding is exceptionally effective at producing intricate and complex plastic shapes with uniform wall thickness. Achieving your custom product designs in a single cycle reduces the need for secondary operations and all of the complications that come with them. Features such as undercuts, ribs, and bosses can be easily incorporated into the design to simplify your overall production process and potentially reduce your cost per part.

Injection molding is also compatible with a broad range of different plastic materials. That means you have flexibility in terms of material selection based on the desired properties of the final product. Material versatility gives you more options for customizing the look, performance, and functionality of your products, as well as more options to meet your unique price targets. 

Extremely Efficient and Cost-Effective for the Right Products

While the cost of designing and manufacturing custom molds can be significant, the relatively low per-unit cost of injection molding quickly decreases as the production quantity increases. That’s why injection molding is particularly cost-effective for high-volume runs, which can easily offset the upfront tooling costs.

Injection molding is sometimes the most cost-effective manufacturing solution even for low-volume runs and certain prototyping projects. We can use special low-volume molds manufactured from aluminum or softer mold steels which are easier to machine and modify, which lowers your upfront costs. However, these materials do come with a shorter service life, which is why we typically opt for tougher tool steels in higher-volume projects.

A Relatively Sustainable Manufacturing Process for Custom Plastics

The injection molding process generates minimal waste, and the excess material can be recycled in many cases. Sprue, runners, and other scrap materials can be reground and reused, contributing to the overall sustainability of the process.

While plastic manufacturing isn’t typically associated with eco-friendliness, injection molding is one of the most efficient means of making many of the critical plastic products in modern life. That efficiency is especially important in the modern marketplace, which increasingly demands greener products and stricter sustainability initiatives.
