Advantages of injection molding:

1. Injection molding provides complex part design

Injection molding can handle highly complex parts, provide consistency, and provide the ability to manufacture millions of nearly identical parts. The effectiveness of high-volume injection molding and the maximization of part accuracy and quality means that key design elements are considered.

Part design must maximize the efficiency inherent in high-volume molding. With the ideal design, parts can be manufactured in high quality without sacrificing complexity.

2. Injection molding can improve production efficiency and speed

There are several good reasons why this is the most common and effective form of molding. First, compared to other methods, the injection molding process is faster, and the high production yield makes it more efficient.

The speed depends on the complexity and size of the mold, but it is only about 15-120 seconds between each molding cycle. Due to the shorter cycles between cycles, more injection molded parts can be produced in a given production time.

3. Injection molding strength is greater

Over the years, the strength and durability of plastics have improved significantly. Modern lightweight thermoplastics can withstand even the harshest environments as well as metal parts and, in some cases, even exceed metal.

In addition, more than 25,000 engineered materials are available for complex injection molding applications. High-performance plastic blends and hybrids can also be manufactured to meet specific part requirements and characteristics, such as high tensile strength.

4. Injection molding is flexible in terms of color and material

The plastic injection molding process provides flexibility. This flexibility can be seen in the characteristics of the plastics used, as well as the ability of the original equipment manufacturer to customize the color selection to meet the requirements of a particular project. The benefit of plastic injection molding is that it gives Oems freedom of design choice, especially when compared to metals. Many materials can be used.

The molding process can obtain the desired color by adjusting plastics, additives and biocompatibility, resulting in transparent parts or a variety of colors. However, when a product often requires multiple colors, this can be achieved by encapsulation molding.

5. Injection molding can reduce waste

Compared with traditional manufacturing processes, plastic injection molding processes produce very little post-production waste. Any waste plastic usually comes from sprue and runner. However, any unused or discarded plastic can be re-ground and recycled for future use.

6. Low labor cost of injection molding

The labor costs of injection molding operations are relatively low compared to other types of molding processes. The ability to produce high-level parts at high productivity helps reduce manufacturing costs through their efficiency and effectiveness.

Molding equipment often comes with automatic pouring, automated process tools to keep operations simple and mass production carried out with minimal supervision.

7. Injection molding offers a variety of surfaces

Most injection molded parts have a smooth surface finish that is close to the desired final appearance. However, the sleek look is not suitable for all applications. Depending on the physical and chemical properties of the plastic material used, the surface finish created by the plastic injection molding manufacturing process does not require a secondary operation. The process offers flexibility in surface treatment, from matte surfaces and unique textures to sculpting.

8. Injection molding to create lightweight products

While they are most prevalent in the automotive industry, Oems use lightweight plastic injection molding products in many industries. Using plastic parts helps to reduce weight compared to using metal parts. Today, high-strength, lightweight thermoplastics can replace metal parts with little difference in strength or durability, just in weight.

9. Injection molding can use many types of plastics

Complex part designs often require components made of different materials. While this may seem simple, safely combining plastics can be very complicated. In any case, by guaranteeing compatibility, the plastic expertise of the mold project engineer reduces the risk of defects, injuries and warranty claims.

10. Injection molding has consistency

Producing high-volume but complex plastic parts requires a consistent, repeatable process to achieve a design with tight tolerances. The injection molding production process helps ensure consistent quality, as the same mold is continuously used for each part and is backed by the continuous improvement practices of the injection molding machine, which incorporate current leading technology.

11. Injection molding can create precision products

Properly maintained modern high-speed injection mould equipment allows the mass production of precision moulded plastic parts. This molding process is optimal for the production of plastic parts such as connectors and gears that require high precision production, with tolerances up to +/-0.0002 inches.

12. Injection molding shortens product development time

The different skill sets of injection mold engineers can help Oems achieve shorter product development times. Doing so ensures faster production cycles and brings defect-free parts to market faster, which is a decisive competitive advantage for manufacturers.
