Injection molding is a manufacturing process used to produce prototypes and real products. It is reliable and efficient because it allows for the production of complex product parts with higher quality and throughput. The injection molding process depends heavily on the design and materials used in better production. In this article, Injection molding machine Coil Slitting Linewill discuss the characteristics of aluminum injection molding.


What is it?

Aluminum injection molding is an innovative technology based on injection molding for the production of parts (prototypes/real products) using aluminum molds. It is the perfect alternative to steel injection molding for additive manufacturing and is widely used in automotive, aerospace and industrial processes.
Aluminum injection molding is ideal because it guarantees easy production of complex products with a minimum number of parts. In addition, it guarantees stable products with consistent structure, high precision and smooth surfaces.

Advantages

- Cost

Aluminum injection molds are less expensive than the steel used to make them. The overall value of the mold and return on investment depends heavily on how the mold is used. However, if all other factors are equal, the initial tooling investment for aluminum will be less.


- Fast

Aluminum injection molding ensures a faster path to product production. Steel injection molding can take several months from the design of the mold to the realization of the final product. However, aluminum injection molding takes only a few days to create the mold, prototype and manufacture the final product.


- Suitable for small batches

For low volume production of parts, aluminum injection molds offer better value. This is due to their reliability in providing lower upfront costs and producing thousands of reliable parts.


- Better products

One of the biggest causes of part defects, such as dents, voids and burn marks, is uneven heating and cooling. The excellent heat dissipation properties of aluminum injection molds provide an advantage by allowing the mold to heat and cool quickly and evenly, thereby reducing the number of defective parts and defective products.


- Easy to retrofit

Aluminum injection molds are made of softer materials and are designed to be separable and straightforward. This feature makes it easy to repair and modify aluminum injection molds in the event of an error.

Disadvantages

- Limited Surface Finishes

Compared to steel molds, aluminum plastic injection molds offer a limited surface finish due to their low density. The high density of steel allows for a variety of textures and custom finishes to be selected by adding steel inserts.


- Flash Part

Flashover is excess material that forms on the mold due to worn cavities that no longer fit tightly. After thousands of production cycles, aluminum plastic injection molds can wear and fail, resulting in product overflow.


- Fewer Products

Aluminum injection molds cannot withstand the high temperatures and pressures associated with the injection molding process for extended periods of time. As a result, they are not suitable for long-term and high-volume part production.


- Complexity

Due to the impact of molded parts on the mold, engineers cannot improve aluminum mold designs without the need for modifications. However, steel molds can be toughened by heat treatment to handle different densities of developed materials.
