出版 日 03.10.2024

In the world of manufacturing, precision is not just a goal - it's a necessity. As a leader in the manufacture of precision dies, you know that the quality of your products depends on the accuracy of your measurements. But do you use the latest developments in precise MEASUREMENT to stay ahead of the competition? Discover how the latest measurement technology can transform your quality assurance processes and give you the competitive edge you need.

Increase the quality of your precision dies with the right measuring technology

What exactly is a precision die?

Imagine a tool so precise that it can shape metal into intricate components. And these components can then be used in all industries from automotive to medical devices. Such a tool is called a precision die. The simpler term "punch" is also often used. These dies are essential for various forming processes such as punching, pressing, bending and deep drawing. They play a crucial role in the production of metal components for industries such as

  • Automotive industry
  • Plastics
  • Electric
  • Textiles
  • Medical technology

Every year, the complexity and quality requirements for these parts increase, meaning that high-quality, intelligent tooling is the key to maintaining competitiveness. Precision die measurement is one of Bruker Alicona's core competences. Here you get some additional insights. 

The crucial role of precision die measurement

Accurate measurements are the backbone of quality assurance in the production of precision dies. Here's why:

  • Precise measurements help to minimize material waste, resulting in considerable cost savings.
  • By guaranteeing exact dimensions, manufacturers can reduce the amount of raw material required.
  • Precise measurements rationalize the production process and enable shorter throughput times.
  • Consistent measurements ensure that each part meets the required specifications, reducing the risk of errors.
  • The ultimate goal is to achieve maximum precision to ensure that every component fits perfectly and functions as intended.

What is actually being measured here?

Various aspects of the production of molds and dies are measured to ensure quality:

stamp precision die measurement
  • The dimensions are checked to ensure that each part corresponds exactly to the specifications.
  • The surface is inspected for any imperfections that could affect the performance of the tool.
  • The material properties are verified to ensure that the materials used comply with the required standards.

Tailor-made solutions for different stamp measurement requirements

In the world of precision die manufacturing, different companies have different needs. Some companies focus on the production of end products and often have their own tool shop, while others specialize in the supply of tools or individual manufacturing processes. There are also hybrid models that combine both approaches, i.e. manufacturing end products and supplying tools to other companies. Understanding these different needs is critical to providing the right measurement solutions that increase efficiency, ensure quality and drive success, which is Bruker Alicona's goal.

It gets even more complex: Why precise measurement of progressive dies is essential

Progressive dies combine the technically different processes of stamping and forming technology. In order to guarantee the quality of the component, the tool must work precisely and all production steps must be perfectly coordinated. Precise bending angles, punching depths, tight tolerances and high repeat accuracy are required. Component geometries are becoming increasingly complex, and processes need to be faster, more energy-efficient and more economical.

A punching tool or progressive die has a highly complex structure consisting of various tool plates, plate inserts, dies and punches or embossing and bending tools. The workpiece is transported from stage to stage by the carrier belt and separated from the belt in the last stage. High stroke rates and short set-up times can keep unit costs low. The stroke rates of progressive dies are 45 to 55 strokes per minute for simple and flat parts.

The art of manufacturing precision molds

The shaping geometry is the most critical area of a die and is manufactured with the greatest possible precision. Maintaining the basic shape accuracy and position in relation to the mounting surfaces is critical. Punches can be mounted in a variety of ways, including geometric clamping, bolted connections, form-fit fasteners and quick-change systems. Reference surfaces are essential as they serve as fixing points or references for the production of fixing points.

Smooth replacement of punches with consistent component quality is essential. High demands on dimensional accuracy, shaping and surface quality must be met. Consistent quality across multiple injection molding machines is required. Tolerances <10µm require high machine accuracy and expertise.

How to rock the precise measurement of your dies 

Bruker Alicona uses Advanced Focus-Variation and Vertical Focus Probing technologies for data acquisition. These methods enable highly accurate measurements on a variety of surfaces, even highly polished or reflective ones pose no challenge. The user interface for these solutions is MetMaX metrology software, which breaks the measurement process down to just a few clicks. Using your CAD files, which may even already contain PMI, the measurement strategy can be generated automatically, taking into account the deviation of the surface from the shape, the reference points and the offset data of the production machine.

Data acquisition includes a complete scan of the forming geometry and a partial measurement of the lateral surfaces using these advanced techniques. With the Advanced Focus-Variation, complex shapes and shiny surfaces, which are often found on punches, can be measured with little effort.

The real advantages of such a measurement

The high-precision measurement offers several advantages.

  • Early detection of dimensional inaccuracies prevents faulty production
  • It supports process optimization through the correct interpretation of influencing factors.
  • It is proof of the quality of the end product, as the stamp is decisive for the shape.
  • It reduces waste by ensuring the exact geometry of the die.
  • Ensures an indisputable representation of the production chain of the end product.

Conclusion: Why precise tool measurement is your key to success

In the competitive world of precision toolmaking, quality assurance is the key to success. By using advanced 3D optical measurement techniques, manufacturers can ensure the highest levels of precision and quality in their products.
