SPI Mold Classification for Injection Molds
We fabricate custom injection molds strictly aligned with SPI (Society of the Plastics Industry) classification standards, scaling from rapid prototype tools to ultra-durable production molds. Our engineering team assists you in selecting the ideal mold class based on target production volumes, material specifications, and anticipated tool longevity.
| 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. |
Selecting the Ideal Tooling Solution
Selecting the optimal mold configuration depends closely on your projected production volumes, geometrical complexity, material properties, and capital budget. Essential criteria to assess include anticipated tool life measured in total shot cycles, strictness of dimensional tolerances, unit economics at scale, and total lead time from final design sign-off to initial sample delivery.
Below is an executive comparison of leading mold categories to help you determine the precise engineering fit for your program.
◉ Plastic injection molds engineered for high-volume thermoplastic components requiring exceptional dimensional repeatability and surface fidelity.
◉Die casting dies optimized for non-ferrous metal alloys, ensuring superior structural integrity and smooth surface finishes.
◉ Advanced metal injection molding (MIM) tooling tailored to bridge the gap for intricate, near-net-shape components forged from stainless steels and high-performance alloys.
◉Investment casting pattern tooling that lowers initial setup barriers for complex metallic parts of moderate geometric intricacy.
◉Extrusion dies built for continuous manufacturing runs across both aluminum structural profiles and thermoplastic shapes.
Injection Mold Making Process
Crafting high-performance custom molds demands rigorous technical expertise, precision machining, and strict quality control. While every tooling project features unique design criteria, a standard manufacturing lifecycle typically encompasses the following structured phases:
DFM
Upon project confirmation and data receipt, our engineering team performs an immediate feasibility evaluation to optimize parting lines, gate positioning, draft angles, and wall thickness uniformity.
Mold design and mold flow analysis
Utilizing state-of-the-art predictive simulation software, we model thermoplastic behavior, melt fronts, and thermal distribution within the cavity to refine runner layouts and prevent potential structural defects prior to cutting steel.
CNC machining and EDM
Core and cavity components are manufactured using high-speed multi-axis milling, electrical discharge machining (EDM), and wire cutting, leveraging premium tool steels, aluminum alloys, or engineered polymers specified for the project.
T1 sample
Following initial tooling assembly, we conduct first-article sampling (T1 trials) to validate critical dimensions, mechanical assembly fits, and surface finish aesthetics against your exact engineering drawings.
Improvement if necessary
Based on rigorous CMM inspection reports and T1 trial feedback, our master toolmakers fine-tune, texture, and polish mold components to achieve ultimate dimensional accuracy.
Commence production and shipping
Once final specifications and quality sign-offs are secured, the completed tooling undergoes rigorous trial verification and secure export packaging before dispatching to your facility.
