What is the scope of the project?

Determining the scope of your project is perhaps the most vital step in identifying the appropriate tooling method. If you are developing parts for pre-production, aluminum tooling is typically the best choice. This approach is favored when the project's requirements necessitate the use of end production-grade injection mold materials. Aluminum tooling is cost-effective and offers quick turnaround times. If specific material requirements are not critical, consider alternative methods such as RTV Molding or 3D Printing.

For production parts, it's essential to evaluate factors like annual usage estimates (EAUs) and the anticipated duration of the project.

How does part size affect tooling?

The dimensions of the part are crucial when selecting tooling. Larger components generally require standalone tools, whereas smaller parts can often utilize more economical alternatives. Insert tools are especially advantageous for smaller items. By using an insert tool, which fits into a standard base unit on the injection press, you can significantly reduce costs. For instance, if your part is a small housing measuring 3" x 2" x 1/2", instead of creating a full standalone tool, an insert tool made of aluminum or steel would suffice. This method minimizes waste and is economically efficient for producing smaller components, with insert sizes ranging from 5" x 5" to 11" x 14".

How does part volume affect tooling?

Part volume plays a significant role in tooling choices, especially when production requirements increase. Typically, a single cavity tool is sufficient for lower production volumes, such as a few hundred to a few thousand parts annually. However, as demand rises, it becomes advantageous to implement multiple cavities in the tool to enhance efficiency and reduce costs per part. When project longevity or volume forecasts are uncertain, starting with single cavity tools is advisable, with the option of transitioning to multi-cavity setups later. Although multi-cavity tools require a higher initial investment, they can greatly decrease the piece price as production scales.

Does part material affect tooling?

Indeed, the type of part material has a direct impact on tooling decisions. Materials such as Polypropylene, which are mild on molds, can extend tool lifespan significantly. Conversely, more abrasive materials like Glass Filled Nylon can accelerate tool wear and reduce longevity. This is a critical consideration, especially for projects with life cycles of 8,000 to 12,000 pieces when choosing between aluminum or steel tooling.

Does part geometry affect tooling?

Absolutely, part geometry is assessed meticulously during the quoting process. Features such as undercuts, cores, and the required surface finishes (e.g., grained, polished, or textured) all influence tooling choices.

What is the life expectancy of a tool?

Aluminum tools typically last between 2,000 to 10,000 parts, depending on factors such as the aluminum grade, part material, and geometry. In contrast, steel tools can endure for 100,000 parts or more based on similar variables, but may require refurbishment after extended use.

What is the timeline to build a tool?

The timeline for tool construction varies, but generally, aluminum tools take between 4-6 weeks for small parts and 6-10 weeks for larger ones. For steel tools, expect timelines of around 6-8 weeks for smaller parts and 8-12 weeks for larger counterparts.

What is the cost difference for Injection Mold Tooling?

While costs can vary widely based on specific project requirements, steel tools typically range from 20-30% higher in cost than aluminum tools.
