The difference between precision metal stamping molds and plastic processing molds
04-21 / 2023

What is the difference between precision metal stamping molds and plastic processing molds? Many people may not be able to distinguish and believe that precision metal stamping molds are made of hardware, while plastic processing molds are made of plastic. Today, the editor of a hardware stamping manufacturer will explain the difference between hardware stamping molds and plastic processing molds.

The difference between precision hardware stamping molds and plastic processing molds:


1. Precision metal stamping molds are specialized tools used in industrial production to produce parts or products of the desired shape from metal materials using various presses and specialized tools installed on the presses. These specialized tools are collectively referred to as metal stamping molds, and the processed products are called metal stamping parts.


2. Plastic processing molds are a combination of plastic molds used for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding. It mainly includes a concave mold with a variable cavity composed of a concave mold composite substrate, a concave mold component, and a concave mold composite card, and a convex mold with a variable core composed of a convex mold composite substrate, a convex mold component, a convex mold composite card, a cavity cutting component, and a side cutting composite plate. Coordinate changes in mold convex, concave, and auxiliary forming systems. Can process series of plastic parts of different shapes and sizes.


3. The fundamental difference between them is that precision metal stamping molds produce hardware products, while plastic molds produce plastic products, and the structure of the molds is also different. Plastic molds have a cooling system, while hardware molds do not. The molding principle of the product is also different. Plastic molds are formed by cooling after injection molding, while hardware molds are formed by cold pressing of standard thickness steel plates.


4. From the perspective of the functions of molds, hardware molds are mass production tools for metal products. The materials used are generally iron, copper, or aluminum, while plastic molds are used for plastic products, and the raw materials used are also plastic materials.
