Precision Stamping Techniques: Applications and Future Trends


Precision stamping technology is an evolution of standard stamping techniques.

It involves enhancing the guiding precision of the punch and die, reducing the clearance between the male and female molds, increasing reverse ejection pressure, and V-ring edge crimping pressure.

Under intense tridirectional compression stress, precision stamping is achieved and can be combined with other compound forming processes to produce precision stamping parts with higher dimensions and surface roughness than standard stamping.

With industries such as telecommunications, automotive, equipment, and consumer electronics undergoing transformations and upgrades like a spring harvest after rain, the demand for key components necessary for intelligent manufacturing, such as signal collection, connection, transmission, control, execution, motors, and electrical appliances, has dramatically increased.

As product quality becomes more precise and component size decreases, precision stamping technology has found extensive application and development.

Many businesses are utilizing precision stamping technology for small, high-precision, complex-structured precision parts, ensuring not only the shape, size precision, and consistency of the processed components, but also an improved response rate to customers, higher production efficiency, and overall business benefits.

Advantages of Precision Stamping Technology

Precision stamping technology, an indispensable advanced manufacturing technology in modern production, involves multiple high-tech fields such as precision press technology, high-precision stamping mold technology, material technology, high-performance die technology, mold material technology, and intelligent control technology.

It is highly valued by all industrial production sectors in the national economy. Currently, advanced manufacturing technology is the research and development focus worldwide, especially in our highly globalized economy.

Precision stamping technology holds a crucial position due to its distinct advantages compared to other manufacturing techniques.

High Quality Components

Precision stamping improves the guiding precision of the press and die, the manufacturing precision of the mold, and reduces the clearance between the male and female molds.

It greatly enhances the dimensional accuracy and surface roughness of the punched cross-section of components when combined with the lubrication and cooling provided by precision stamping oil, resulting in very high-quality processed components.

Excellent Consistency

Precision stamping molds use special mold materials and heat treatment processes, giving them high dimensional accuracy and a lifespan over ten times longer than standard stamping molds.

This results in high consistency in the dimensional accuracy, shape, and positional accuracy of the processed components, improving the interchangeability of components, reducing measurement selection during assembly, and ensuring product consistency.

High Production Efficiency

Compared to standard stamping, precision stamping improves the dimensional accuracy, shape, and positional accuracy of components, reducing subsequent precision processing procedures, saving processing time on other equipment, and reducing the number of times intermediate products are turned over.

It significantly shortens the manufacturing cycle of components and reduces capital occupation, greatly enhancing the overall economic benefits of the enterprise.

High-speed precision presses have been developed domestically and abroad for specific industries, producing parts with high precision, good surface quality, and long mold life.

High Degree of Automation

Precision stamping combines high-precision stamping mold technology with intelligent control technology and stamping automation technology, significantly reducing personnel dependency.

This not only improves working conditions and reduces costs but also ensures personnel safety during stamping production, changing the concept of stamping production.

Therefore, precision stamping and stamping automation have been widely used in various manufacturing fields such as electronics, communications, motors and electrical appliances, instrumentation, household appliances, automobiles, and military industries.

It is increasingly seen by many entrepreneurs as an important means to enhance enterprise core competitiveness.

Good Comprehensive Benefits

The precision stamping technology have excellent applications in real-world manufacturing. The products manufactured in bulk using high-speed precision stamping technology not only have high quality, good consistency, and high production efficiency, but also save manpower, reduce energy consumption, shorten manufacturing cycles, and reduce capital occupation under the push of stamping automation.

This enhances the economic benefits of enterprises and is increasingly accepted and recognized by them.

Over the past decade, with the widespread application of multi-station presses and multi-function stamping dies, especially in the automotive industry, multi-station presses have reduced the work that originally required several process equipment to be completed to one or two, optimizing the stamping process and reducing the number of stamping equipment.

Precision stamping technology has seen unprecedented development in the automotive industry.

For instance, the traditional two-time stamping process, due to the cold hardening caused by deep drawing, could not remove wrinkles.

After adopting precision deep drawing, not only can the generation of wrinkles be suppressed, but subsequent processes can be reduced, lowering the investment cost of equipment and material costs, and enhancing economic efficiency.
