1. Plastic mold is a combined plastic mold used for compression molding, extrusion molding, injection molding, blow molding and low-plastic molding, and changes in mold convex, concave mold and auxiliary molding systems. It can process a series of Plastic Parts of different shapes and sizes.
2. Hardware molds are parts or products that use various presses and special tools installed on the presses in industrial production to process metal materials according to the shape of the finished product through pressure. This special tool is collectively called hardware molds.
3. From the function of the mold, the metal mold is a mass production tool for metal products. The materials used are generally iron, copper or aluminum. The plastic mold is made of plastic products, and the raw materials used are also plastic raw materials.
4. The most essential difference between the metal mold and the plastic mold is that the structure of the mold is different. The plastic mold has a cooling system, but the metal mold does not. The molding principle of the product is also different. The plastic mold is formed by cooling after injection molding, and the metal mold is stamped and formed with a standard thickness of steel plate.
5. Both metal molds and plastic molds are made of steel. Stamping metal molds generally use cold-worked steel. If it is a die-casting mold, hot-worked steel is required. Plastic molds are generally hot-worked steel. Including metal die-casting mold) without gating system and cooling system, it can be understood as follows: plastic mold processing is to flow liquid plastic into the cavity for cooling and molding in a sealed space,Metal stamping dies have the following advantages.
Due to the use of mold processing, it is possible to obtain metal stamping parts with thin walls, light weight, good rigidity, high surface quality and complex shapes that other processing methods cannot or are difficult to manufacture. The dimensional accuracy of the stamping parts is guaranteed by the mold, which has the same characteristics, so the quality is stable and the interchangeability is good. For ordinary presses, dozens of pieces can be produced per minute, while high-speed presses can produce hundreds of thousands of pieces per minute. So it is an efficient processing method.
Plastic processing molds have the following advantages The high tolerance of plastic molds is repeatable, the labor cost is low, a wide range of materials can be used, the waste loss is relatively small compared to metal stamping, and the plastic mold does not need to continue to improve the part after molding.
With the continuous improvement of the functions, properties and quality of plastic products in modern society, in order to meet the relevant requirements of the society for plastic molds, higher production results are required, and this is undoubtedly inseparable from the foundational role of design work. The relevant designers need to realize the perfection and improvement of the design work through practical investigation, standardized design, and the use of new technologies, so as to lay a guarantee for high-quality plastic molds and produce products that meet the needs of the times.
