Is it absurd to use proto molds and prototype injection moulding? As most designers know, plastic injection molding is best used for large quantities of production-quality (i.e., non-prototype) items. It’s possible that you’ve also heard that aluminum injection molds are meant for smaller volumes, steel injection molds for larger numbers, and both kinds of proto molds are too costly.

Aluminum vs. Steel MoldsThe choice of mold material is of paramount importance. While aluminum is the most cost-effective option, it may not deliver injection-molded parts with the tight tolerances required for precision applications. Steel molds, on the other hand, excel in achieving precise tolerances, with the capacity to machine to tolerances as tight as +/-0.001 inches, a marked contrast to aluminum’s typical +/-0.005 inches.

Their core business serves agricultural, industrial, and commercial sectors, producing durable water storage tanks, chemical storage containers, and custom-molded products.

Main Services: Provides plastic injection moulding, product design and development, and precision toolmaking services for medical, automotive, and consumer products.

While these categories aren’t the only way to classify prototypes, they provide a structured framework for the discussion of proto molds that follows.

Hardened steel is typically reserved for production molds, given its greater durability (i.e., more cycles) and the ability to achieve stringent tolerances. For applications demanding tight tolerances, such as in the medical or aerospace sectors, aluminum falls short.

Consider this scenario: molding one proof-of-concept prototype versus crafting 100 pre-production prototypes, both requiring a $10,000 tool. The per-part tooling cost for one proof-of-concept prototype is $10,000, while for 100 pre-production prototypes, it’s a significantly reduced $100—a substantial cost differential.

When your part design is still in its early stages, you might contemplate the use of more cost-effective commodity plastics, even if they do not possess the same mechanical properties as your intended production materials. As an illustration, consider PEEK, an engineering plastic frequently employed in medical devices. PEEK comes at a notably higher cost compared to other polymers and might involve a high minimum order quantity (MOQ) if your supplier does not purchase it in quantities substantial enough to secure a discount.

Master Unit Die (MUD) inserts, featuring a standard mold frame with customizable, removable inserts, provide a cost-effective alternative for initial tooling, potentially reducing costs by up to 66%. Despite the cost savings, MUD molds maintain the complexity often needed for proto molds designs, allowing for efficient modifications to the insert in response to design changes.

One advantage of injection molding is the adaptability in choosing various mold materials. For instance, the base of proto molds can be crafted from aluminum or soft/semi-hardened steel, while the inserts may be made of soft, semi-hardened, or hardened steel. Additionally, if your mold requires movable components like lifters, these elements can also be fashioned from steel.

ADDE is a premier Australian firm renowned for its excellence in plastic injection molding, especially in Australian mold injection.

For a works-like prototype, you may opt for a less expensive material, such as polyphenylsulfone (PPSU), which can be a suitable choice. However, it’s important to note that selecting a material other than PEEK might not offer a comprehensive assessment of your part’s moldability. Given that both PPSU and PEEK are available as 3D-printing filaments, you might explore the possibility of utilizing additive manufacturing instead. This approach not only reduces tooling costs but also grants you the flexibility to use your preferred plastic material. It seems straightforward, doesn’t it?

For many proof-of-concept and looks-like prototypes, the expenditure on an injection-molding tool may not be justified. Typically, in these early stages, designers only require a limited quantity of one or two parts. The cost of an injection mold, when divided among such a small production run, often makes it an impractical choice.

Additionally, the file formats used in 3D printing and plastic injection molding differ. 3D printing relies on STL files, which define objects as a triangle mesh, while injection molded parts are typically defined using CAD files that are parameter-driven. To utilize 3D printing files for injection molding, a conversion process is required to transform the mesh into a shape and then into a solid.

Should any of this resonate with you, it’s time to reconsider your production and prototyping alternatives as well as unlearn some of the advice you’ve been given. Injecting plastic is indeed a high-volume manufacturing method. However, it can also be used for low-volume production and prototyping at times. It’s not simply aluminum vs. steel when it comes to injection molds.

Proto molds or Prototype injection molding and production injection molding share the ability to utilize the same plastics. However, it’s crucial to be aware that certain abrasive materials, such as glass-filled nylon, can accelerate wear and tear on proto molds. This is primarily because proto molds are typically crafted from softer materials. Nonetheless, if your intention is to prototype 100 parts, the issue of wear becomes less critical compared to the wear and tear associated with a full-scale production run of 10,000 parts.

Tolerances, which refer to the allowable part-to-part variations, also differ between 3D printing and injection molding. Most additive manufacturing technologies have dimensional tolerances of at least 0.1 mm, resulting in greater deviations compared to injection molding. Moreover, injection molding typically involves two types of tolerances: commercial and fine.

One crucial aspect to remember is that 3D printing and injection molding have different design rules, including minimum wall thickness. Walls that are too thick, too thin, or non-uniform can often lead to failures in production injection molding. To avoid such issues, proto molds and prototype injection molding is recommended as it allows you to identify potential production challenges and make necessary adjustments.
