Progressive molds belong to hardware molds, and their processing technology is directly related to the life of the product. After years of development, its processing technology has become increasingly mature. Today, the editor has summarized several common finishing methods for you. Let’s take a look. Bar.

1. Manual grinding and polishing

This is a relatively traditional processing method, which relies entirely on the operator's technology and experience. The production is time-consuming and slow in efficiency. If the fundraising shows that there are some complex joints or curved surfaces, it will be difficult to process.

2. Mechanical finishing (grinding)

Today's more common grinding equipment includes internal and external cylindrical grinders, surface grinders, etc. In order to ensure high product accuracy, it is necessary to select a suitable grinder according to the specifications and size of the progressive die. For example, you can choose an internal and external cylindrical grinder for arc surfaces. For the plate type, you can choose a surface grinder.

3. Mechanical finishing (CNC milling machine)

This is a CNC automated processing method. It not only has good processing accuracy but is also fast in efficient. It has become one of the main methods of finishing machining of progressive dies today.

To further elaborate on the finishing methods for progressive molds and progressive dies, let's delve into additional techniques and considerations that are crucial in the manufacturing process.

4. Electrical Discharge Machining (EDM)

Electrical Discharge Machining (EDM) is another precise finishing method commonly used in the manufacturing of progressive molds. This method uses electrical discharges to erode material from the workpiece, enabling the creation of intricate shapes and fine details that are difficult to achieve with traditional machining. EDM is particularly useful for hard materials and complex geometries, ensuring high precision and ideal surface finish. However, it is essential to carefully control the process parameters to avoid surface damage and ensure dimensional accuracy.

5. Laser Cutting and Polishing

Laser cutting and polishing are modern techniques that provide high accuracy and a fine surface finish for progressive dies. Laser cutting uses a focused laser beam to cut materials with precision, making it suitable for detailed and intricate designs. Laser polishing, on the other hand, employs laser technology to smooth and refine the surface of the mold. This method offers advantages such as less material waste, high repeatability, and the ability to process hard-to-reach areas. However, it requires advanced equipment and expertise to achieve good results.

6. Surface Treatment and Coating

Surface treatment and coating are essential steps in enhancing the durability and performance of progressive molds. Treatments such as nitriding, carburizing, and cryogenic processing can increase the hardness and wear resistance of the mold surface. Additionally, applying coatings like TiN (titanium nitride) or DLC (diamond-like carbon) can further enhance the mold's resistance to wear, corrosion, and friction. These treatments and coatings extend the life of the progressive dies and improve their performance in high-volume production.

7. Quality Inspection and Control

Quality inspection and control are critical to ensuring the precision and reliability of progressive molds and progressive dies. Advanced inspection techniques, such as coordinate measuring machines (CMM), optical measurement systems, and laser scanners, are used to verify the dimensional accuracy and surface quality of the finished components. Regular inspection and quality control help detect any deviations or defects early, allowing for timely corrections and ensuring consistent product quality.

8. Maintenance and Reconditioning

Proper maintenance and reconditioning of progressive molds are vital for sustaining their performance and extending their service life. Regular cleaning, lubrication, and inspection of the molds help prevent wear and damage. Additionally, reconditioning processes such as re-grinding, re-polishing, and re-coating can restore the molds to their original specifications, reducing downtime and production costs. Implementing a scheduled maintenance program ensures that the progressive dies remain in good condition and continue to deliver high-quality results.

In summary, the finishing methods for progressive molds and progressive dies have evolved significantly, offering a range of techniques to achieve high precision and durability. From traditional manual grinding and polishing to advanced CNC milling, EDM, and laser processing, each method has its advantages and applications. Additionally, surface treatments, quality control, and regular maintenance play crucial roles in enhancing the performance and longevity of the molds. By mastering these finishing methods, manufacturers can produce reliable and efficient progressive dies, meeting the demanding requirements of modern industrial applications.
