In the vast field of industrial production, moulds play an important role. Among them, secondary moulds, as a special type of moulds, with their unique processes and functions, strongly support the fine processing of products. What is a secondary mould? What are its main characteristics and types? The following will be analysed in detail from four aspects.

Definition and function

As the name suggests, secondary moulds refer to moulds that are processed and deformed after the product has been moulded once. This type of mould is usually used in the processing and production of polymeric materials such as metals, plastics and rubber. Its main function is to fine-tune the shape, geometric dimensions, etc. of the product based on the initial moulding process to achieve higher product quality. By processing secondary moulds, the product can have a finer contour, higher dimensional accuracy and better surface quality.

Structural characteristics

The structure of the secondary mould is relatively complex, with high working performance and high production cost. This is mainly due to its precise design and manufacturing process. To meet the requirements of specific product processing and production, secondary moulds must go through strict material selection, design, processing and inspection. These links ensure the high precision, high strength and high wear resistance of the mould, thereby ensuring the processing quality and production efficiency of the product.

Common types

There are many kinds of secondary moulds, which can be divided into many types according to different processing methods and material properties. Among them, press secondary moulds are mainly used in forging production, and the material is plastically deformed in the mould by applying pressure; injection machine secondary moulds are widely used in plastic product processing, and the product is formed by injecting plastic melt into the mould and cooling and solidifying; extruder secondary moulds are mainly used in the processing and production of rubber products or plastic pipes, and continuous products are formed by extruding materials and passing them through the channels of the mould.

Technical features

In addition to the above design and type characteristics, secondary moulds also have some unique technical features. For example, it can improve production efficiency and reduce production costs through batch processing of moulds; it can ensure product quality and ensure the dimensional accuracy and surface quality of the product through the high precision and stability of the mould; in addition, secondary moulds can also meet the needs of product upgrading and replacement, and adapt to the processing requirements of new products by modifying the design of the mould.

In summary, as a high-precision production and processing tool, secondary moulds have wide application prospects in industrial production. Their definition, structural features, common types and technical characteristics together constitute their unique value and significance. By thoroughly understanding these aspects, we can better understand and apply secondary moulds and make greater contributions to the development of industrial production.
