The Development of Stamping Moulds
Stamping moulds are special tools used for processing plastic material and metal materials. Their development originated from ancient metalworking processes such as moulding, casting and forging. The earliest stamping moulds were used in the Byzantine Empire between the 5th and 7th centuries. Since then, numerous changes and improvements have been made over time to make stamping moulds more efficient and effective for use.
The introduction of metalworking technologies during the Industrial Revolution gave a major boost to the development of stamping moulds. These technologies enabled the mass production of stamped metal parts by using automated machines, which made manufacturing and assembly processes much faster and more efficient.
Today, the use and application of stamping moulds have grown exponentially in various industries, especially in the automotive industry. Automotive manufacturers have increasingly turned to stamping moulds to produce their parts, due to the cost-effectiveness and accuracy of the resulting stamped parts.
The process of producing stamping moulds involves making moulds in a variety of shapes and sizes and using intricate internal thinning processes to create the desired stamped product. The process of “drawing” the product creates a unique shape, which can be used to produce parts with complex grooves, ribs, flanges and other features.
Generally, a common stamping mould consists of two parts – the upper die and the lower die. The upper die is used to hold the shape of the mould and contains the shape, ridges and grooves that need to be stamped into the part or product. The lower die is kept in a stationary position and provides a flat surface against which the part is pressed to achieve the desired shape.
In order to ensure efficient stamping and accurate repeatability, most moulds are made from hardened and tempered tool steel, which is highly resistant to wear and tear in production environments.
Stamping moulds also have a secondary function in die-casting, wherein molten metal is poured into a wooden or metal cavity to form a variety of shapes and sizes. Die-casting is a method that is used to create intricate details and shapes in the finished product.
The production of stamping moulds has become much more affordable and widespread in recent times due to the advancements in CNC (Computer Numerical Control) technology and CAD (Computer Aided Design) software. This has enabled the development of highly sophisticated 3D-shaped moulds that can be used to create intricate parts and shapes in the automotive, aerospace and electronics industries, ensuring accuracy and precision with every stamp.
As the demand for stamping moulds grows, so too do the advancements in the tool-making technologies used to create them. Almost any design can be achieved with the right tools and technologies, ensuring that the process of producing stamping moulds remains cost-effective, efficient and accurate.
Stamping Moulds in English and Chinese
Stamping moulds (冲压模具) are special tools used for making a variety of shapes and sizes in plastic material and metal materials. These moulds are primarily used in industries such as automotive, aerospace and electronics, due to their accuracy, cost-effectiveness and repeatability. Stamping moulds generally consist of two parts – the upper die (上模) and the lower die (下模). The upper die contains the shape, ridges and grooves to be stamped into the part or product, while the lower die provides a flat surface against which the part is pressed for a more accurate shape. The process of producing stamping moulds involves making moulds in a variety of shapes and sizes and using intricate internal thinning processes to create the desired stamped product. This process has become much more affordable and widespread in recent times due to the advancements in CNC (计算机数控) technology and CAD (计算机辅助设计) software.
