Why is injection molding case studies Better?

Injection moulding has a number of advantages. It minimises moulding costs and is a highly repeatable way of producing plastic or elastomeric parts with high precision. Once set up, it can manufacture a large volume of parts per hour, from a wide range of different plastics plus other materials such as liquid silicone rubber.

However, like any manufacturing process, it does have some disadvantages, and if these prove significant to the success of your project, then you may be better off exploring alternative manufacturing technologies such as 3D printing or CNC machining.

In this blog, we will take you through the main advantages of Injection Moulding and explore when it may be better for you to consider an alternative production method.

1. Plastic Injection Molding Provides Complex Part Design

Injection molding can handle highly complex parts, provides uniformity, and offers the ability to make millions of virtually identical parts. The effectiveness of high-volume injection molding and maximization of precision and quality of parts means taking key design elements into account. 

The part design must be created to maximize the efficiency inherent in high-volume molding. With the ideal design, parts can be made with quality without sacrificing complexity. 

2. Plastic Injection Molding Provides High Efficiency and Fast Production

There are a few good reasons that this is the most common and most efficient form of molding. First, the injection molding process is rapid compared to other methods, and the high production output rate makes it even more effective.

The speed is subject to the complexity and size of the mold, but only about 15-120 seconds pass between each molding cycle. With the short period between cycles, more injection molded parts can be produced in a given production time.

3. Plastic Injection Molding Provides Enhanced Strength

The strength and durability of plastics have significantly increased over the years. Modern lightweight thermoplastics can endure even the harshest environments on par with metal parts and, in some cases, may surpass metal. 

In addition, there are more than 25,000 engineered materials that can be used for complex injection-molded applications. High-performance plastic blends and hybrids can also be created to meet particular part requirements and characteristics, such as high tensile strength.

4. Plastic Injection Molding Provides Flexibility in Color and Material

The plastic injection molding process provides flexibility. This flexibility can be in such things as the properties of the plastic being used or in the ability for OEMs to make custom color choices to meet specific project requirements. The benefit of plastic injection molding is the freedom in design choices that it affords to OEMs, especially when compared to metal. Many materials can be used. 

The molding process can create clear parts or various colors by aligning plastics, additives, and biocompatibility to achieve the wanted coloration. However, when multiple colors are often needed in one product, this can be accomplished using overmolding.
