Benefits of Low Volume Injection Molding

One of the challenges of creating a new product is ensuring that you get it to market as quickly as possible so that your competitors don’t beat you to it. However, you still need to make sure that it looks good and works well, or you risk investing your time, money, and reputation on a faulty product that nobody wants. .Discerning manufacturers solve this conundrum, by creating prototypes of the product and relying on low volume injection molding machines to produce high-quality parts in small batches, so they can test and analyze the product throughout the design phase.

 Low volume injection molding is a form of rapid prototyping or rapid tooling. Here are some of the benefits that it offers:

What is low volume injection molding?

Low volume injection molding is a specialized manufacturing process tailored for producing a smaller quantity of parts, often used in the initial stages of product development, small-scale operations, or for customized, specific-use components. When we say “low volume,” we’re typically referring to production runs of a few dozen to several thousand parts, in contrast to high-volume injection molding which commonly involves the production of many thousands to millions of parts.

This approach is ideal for several scenarios: perhaps a company is in the prototype or testing phase and doesn’t require a large number of units, or there’s a need for a custom part not used in mass-scale products. Low volume injection molding is also a preferred strategy when managing the cost-effectiveness of producing a smaller number of units is critical, as it can be more economical than setting up large-scale production for a small run.

One main distinction between low volume and traditional, high-volume injection molding lies in the quantity of the output, but the differences also extend to factors like overall cost, time, and the specificity of applications. While high-volume production might be perfect for generic parts needed in large quantities, low-volume production shines in its flexibility and adaptability to specific, often more complex, design needs.

Design considerations for low-volume injection

When embarking on a low-volume injection molding project, several design considerations come to the forefront to ensure efficiency, cost-effectiveness, and high quality in the manufacturing process.

Wall Thickness: One of the primary considerations in low-volume injection molding is the wall thickness of the parts being produced. Uniform wall thickness is crucial because it ensures the even flow of plastic, minimizes defects, and improves the overall quality of the final product. It’s important to remember that too thick walls may lead to prolonged cooling times and potential deformities, while too thin walls might not be robust enough or may cause difficulties in the molding process.

Identical Parts: In low-volume injection molding, producing identical parts is often a priority, especially when creating components for critical applications where consistency is key. This requires precise control over the molding process, including consistent pressure, temperature, and cycle times, to ensure each part is as close to identical as possible.

Injection Mold Design: The design of the mold itself is a fundamental aspect. For low-volume production, the mold design doesn’t necessarily need to endure millions of cycles, but it still has to maintain precision and reliability. This often means that the mold design can be less complex and, therefore, more cost-effective, but still requires a high degree of engineering expertise to ensure the quality of each produced part.

These considerations are central to optimizing the manufacturing process in low-volume injection molding. They require a detailed understanding of both the design and production aspects, ensuring that even with smaller quantities, the highest standards are met without incurring unnecessary costs or extended timelines. This careful attention to design details not only enhances the quality of the final product but also allows for a more streamlined and efficient production process.
