SPI Mold Classification for Injection Molds
We build custom molds according to SPI standards, ranging from rapid prototype tooling to high-volume production. Our engineers help you select the ideal class based on your volume, material, and target tool life.
| SPI Mold Classification | Expected Tool Life | Investment | Application |
| Class 101 Mold | 1,000,000+ | Highest | Mass production (e.g., automotive, appliances) |
| Class 102 Mold | 1,000,000 | High | Consumer goods, industrial parts |
| Class 103 Mold | 500,000 | Moderate | Electronics, medical devices |
| Class 104 Mold | 100,000 | Low to Moderate | Low-volume manufacturing, prototyping |
| Class 105 Mold | 500 | Low-cost | Rapid prototyping, short-run production |
Materials Used for Custom Mold Making
| Material Name | Material Composition and Detailed Description |
| Aluminum | 2024/7075/6061 alloys, excellent machinability & thermal conductivity. Suitable for low to medium volume production (up to 50k cycles). Lighter weight enables faster production cycles. |
| Plastic | Nylon (wear-resistant), ABS (low-cost), Polypropylene (chemical-resistant). Ideal for rapid prototyping or short-run testing. |
| Tool Steel | H13 (die casting), S7 (impact-resistant), D2 (high-wear stamping). For high-volume production (500k+ cycles) with precision. |
| Stainless Steel | 410/420 grades offer corrosion resistance. Essential for medical/food-grade molds requiring polished surfaces. |
How to Choose the Right Mold
Choosing the right mold type depends on your production volume, part complexity, material, and budget. Key factors to evaluate include expected mold life in shot count, tolerance requirements, unit cost at your target volume, and lead time from design to first article.
Below is a quick comparison of the most common mold categories to help you identify the best fit for your project.
◉ Plastic injection molds are ideal for high-volume thermoplastic parts with tight dimensional repeatability.
◉ Die casting molds suit non-ferrous metal components requiring excellent surface finish and structural integrity.
◉ Metal injection molding bridges the gap for small, complex stainless steel or alloy parts that need near-net-shape accuracy.
◉ Investment casting molds offer a lower tooling cost entry point for metal parts with moderate complexity.
◉ Extrusion dies serve continuous-profile applications in both aluminum and plastic.
Injection Mold Making Process
Mold making is a complex process that requires a high level of skill and experience. Although each case is different, a typical order for a set of molds may go something like this:
DFM
As soon as the customer confirms the order of molds, we will start to do an initial analysis of the parts to get an idea of the part line, gate positions, etc.
Mold design and mold flow analysis
The second step involves the use of predictive modeling software which allows us to see how the molten material will behave when it enters the mold, allowing for further improvements to the design.
CNC machining and EDM
We make the first molds using high-quality machining equipment, with the plastic, steel, aluminum, etc. chosen by the customer.
T1 sample
With the newly made molds, we make a T1 sample to have a clear vision of how the customer’s final molded parts will turn out.
Improvement if necessary
Based on our analysis of the T1 sample, we review the mold design and make any adjustments needed.
Commence production and shipping
We manufacture the molds in accordance with the final specifications before shipping them to the customer.

Learn about some related issues from here
Why use casting instead of a more accessible process like CNC machining?
Metal casting can be used to make very large parts with high tensile strength and complex parts with undercuts. Sometimes there is no alternative.
How long does a mold last?
A well-made, fully harden steel mold may be used for up to a million shots or injections, depending on the mold shape and injection material. Aluminum molds are less durable, which is good for short-run production with tight schedule.
What factors affect mold making lead time?
Lead time varies based on mold complexity, material selection, and current production schedules. Simple prototype molds can be delivered in as few as ten business days, while complex multi-cavity production molds may require several weeks. We provide estimated timelines with every DFM report.
