8480.71.80.45 - Injection type

This HTS classification, 8480.71.80.45, specifically covers molds designed for the injection molding of rubber or plastics, excluding those identified as compression types. Injection molding is a process where molten material is injected into a mold cavity under high pressure, filling the void and solidifying into the desired shape. The molds within this category are precisely engineered to facilitate this high-pressure, high-volume manufacturing technique, forming intricate and detailed plastic or rubber articles.

Distinguishing this category from its sibling, 8480.71.80.60 (Compression type), is crucial. Compression molds are designed for a process where a pre-measured amount of material is placed into the mold cavity, which is then closed under heat and pressure, causing the material to flow and fill the cavity. In contrast, injection molds are built to withstand and direct the forceful flow of molten plastic or rubber from an injection unit directly into the mold cavity. Therefore, the design and engineering principles, particularly in terms of runner systems, gates, and venting, will differ significantly between injection and compression molds.

As this HTS code represents a leaf node within the classification structure, there are no further subcategories. The classification terminates at this level, implying that all molds specifically designed for the injection molding of rubber or plastics, that do not fall under any more granular criteria, will be assigned to this designation. The key determining factor for classification here is the intended use in the injection molding process.
