Treatment of Handsome Steel Model Frames in the Mold Base Industry

In the mold base industry, the treatment of handsome steel model frames plays a crucial role in ensuring the quality and performance of molds. The treatment process involves several stages that aim to enhance the strength, durability, and versatility of the steel model frames. This article provides an overview of the treatment techniques used in the industry.

1. Cleaning and Degreasing

The treatment process begins with the cleaning and degreasing of the steel model frames. This step is essential to remove any dirt, oil, or contaminants that may be present on the surface. Ultrasonic cleaning or chemical cleaning methods are commonly employed to achieve thorough cleaning, ensuring a clean and pure surface for subsequent treatment processes.

2. Preheating

Preheating is typically performed to reduce the risk of thermal stress during the subsequent treatment processes. By slowly raising the temperature of the steel model frames, any internal stresses are effectively minimized, ensuring dimensional stability and preventing distortion or cracking.

3. Quenching

Quenching involves rapidly cooling the steel model frames from a high temperature, typically above the critical point, to room temperature. This process is performed to achieve desirable material properties such as high hardness and improved strength. Water, oil, or polymer solutions are commonly employed as quenching media, depending on the specific requirements of the steel model frames.

4. Tempering

Tempering is a heat treatment process that follows quenching and is used to reduce the brittleness of the steel model frames. It involves reheating the quenched steel to a specific temperature and then gradually cooling it. Tempering helps to improve toughness and ductility, making the frames less prone to cracking or fracturing.

5. Surface Hardening

Surface hardening techniques are employed to improve the wear resistance and surface hardness of the steel model frames. Common techniques include carburizing, nitriding, and induction hardening. These methods introduce carbon or nitrogen into the surface, forming a hard and wear-resistant layer while maintaining the overall toughness of the frames.

6. Shot Blasting

Shot blasting is a surface treatment process that involves propelling abrasive materials at high speed to clean, deburr, or roughen the steel model frames. This process helps to improve the surface finish and remove any leftover impurities, ensuring a smooth and uniform appearance.

7. Precision Machining

Precision machining is often performed to achieve the final dimensions and tolerances required for the steel model frames. This process involves the use of advanced machining techniques such as milling, turning, grinding, and drilling. Precision machining ensures the accuracy and functionality of the frames in the mold base.

Conclusion

In summary, the treatment of handsome steel model frames in the mold base industry involves various processes to enhance their strength, durability, and performance. Cleaning and degreasing, preheating, quenching, tempering, surface hardening, shot blasting, and precision machining are essential steps that contribute to the overall quality of the frames. Through these treatments, the steel model frames are prepared to withstand the demanding requirements of mold production, ensuring optimal performance and longevity.
