8480.71.80.60 - Compression type

This classification covers molds specifically designed for compression molding of rubber or plastics. Compression molding is a process where a pre-measured amount of material is placed into a heated mold cavity, and the mold is closed under pressure, forcing the material to take the shape of the cavity. These molds are essential components in the manufacturing of a wide array of plastic and rubber articles, ranging from automotive parts and gaskets to consumer goods and electronic components. The key defining characteristic is the mold's design and function to accommodate the compression molding technique.

Distinguishing this category from its sibling, 8480.71.80.45 (Injection type), is crucial. Injection type molds are designed for the injection molding process, where molten plastic or rubber is injected under high pressure into a closed mold cavity. The primary difference lies in the mold's construction and the operational method of the molding process it supports. Compression molds are typically simpler in design, relying on the direct application of pressure to the material within the cavity, whereas injection molds are engineered to withstand and channel high-pressure flow of molten material.

As a leaf node, this classification represents the most specific level for molds used in compression molding of rubber or plastics. Therefore, further subdivision does not exist within this specific HTS code. Classification at this level is determined by the confirmed use of the mold for the compression molding process, differentiating it from molds designed for other plastic or rubber forming techniques. Practical considerations for classification include the mold's cavity design, runner system (or lack thereof), and the overall mechanical structure that facilitates the closing action and pressure application characteristic of compression molding.
