The production volume has a direct impact on the die’s service life and cost. For large-scale production, the die needs to withstand higher working intensities and more frequent use. Therefore, it is necessary to select more wear-resistant and durable materials and processes to ensure that the die can endure long-term production demands while reasonably controlling costs to achieve maximum economic benefits.

II. Carefully Selecting Suitable Materials

The performance and quality of a tungsten carbide die largely depend on the selected materials, which is like choosing high-quality saddles for a fine horse. When customizing a tungsten carbide die, it is necessary to carefully select materials from three aspects: material composition, quality, and cost.

Material composition is the key factor determining the properties of tungsten carbide. Tungsten carbide materials are usually composed of elements such as tungsten, cobalt, and carbon, and different compositions endow the materials with different characteristics. For example, materials with a high tungsten content have higher hardness and wear resistance, making them suitable for manufacturing dies with extremely high wear resistance requirements. Increasing the cobalt content appropriately can improve the material’s toughness and impact resistance, enabling the die to withstand larger impact forces without damage. Therefore, it is essential to precisely select the appropriate material composition according to actual requirements to ensure that the die has sufficient hardness, strength, and wear resistance.

Material quality is the cornerstone for ensuring die performance and service life. High-quality tungsten carbide materials should have a uniform organizational structure, good purity, and stable performance. It is advisable to choose reputable and reliable tungsten carbide material suppliers, strictly control the material procurement process, and conduct rigorous testing on the purchased materials to ensure that their quality meets requirements and prevent die failures and product defects caused by material quality issues.

Material cost is an important factor that cannot be overlooked when customizing dies. While ensuring the die’s performance and quality, it is necessary to comprehensively consider material costs. By reasonably selecting materials and optimizing designs, material costs can be reduced, thereby lowering the overall customization cost and enhancing the product’s market competitiveness.

III. Scientifically Designing Die Structures

The design of a die structure is like drawing a precise blueprint, playing a decisive role in the die’s performance and service life. When customizing a tungsten carbide die, it is necessary to scientifically design the die structure from three aspects: structural stability, processing convenience, and maintenance convenience.

Structural stability is the foundation for the reliable operation of the die. The die structure should be designed to be stable and reliable, capable of withstanding various forces and vibrations during the production process, ensuring that no deformation or cracking occurs during long-term use. For example, adopting reasonable reinforcing rib designs and optimizing the structural layout can enhance the overall stiffness and strength of the die and improve its resistance to deformation.

Processing convenience is the key to improving production efficiency. The die structure should be easy to process and assemble, minimizing processing difficulties and time. When designing the die structure, it is necessary to fully consider the characteristics of the processing technology and the processing capabilities of the equipment, reasonably determine the die’s dimensional accuracy and geometric tolerances, and avoid overly complex structures and excessively high precision requirements that are difficult to process. At the same time, it is essential to ensure that the die’s assembly accuracy meets requirements by optimizing the assembly process and using advanced assembly tools, ensuring the consistency of product quality.

Maintenance convenience is an important guarantee for extending the die’s service life. Dies are inevitably subject to wear or damage during use, so it is necessary to design a reasonable maintenance structure to facilitate the maintenance and replacement of die components. For example, adopting a modular design, dividing the die into multiple independent modules, allows for the replacement of a faulty module without disassembling and repairing the entire die, greatly shortening the maintenance time and reducing maintenance costs.

IV. Reasonably Considering Processing Technologies and Equipment

Processing technologies and equipment are powerful tools for creating high-quality tungsten carbide dies, having a direct impact on the die’s processing quality and efficiency. When customizing a tungsten carbide die, it is necessary to reasonably select processing technologies and equipment according to the die’s complexity and precision requirements.

The selection of processing technologies should precisely match the die’s requirements. For dies with extremely high precision requirements, high-precision processing technologies such as electrical discharge machining (EDM) and laser processing can be used. EDM can machine complex cavities and holes with high precision, especially suitable for processing hard materials such as cemented carbide. Laser processing has the advantages of fast processing speed, high precision, and a small heat-affected zone, enabling micro-processing and precision cutting. For dies with simple structures, traditional cutting processing technologies such as turning, milling, and grinding can be used. These technologies are mature and reliable, with relatively low processing costs.

The performance and precision of processing equipment are the keys to ensuring die processing quality. It is advisable to choose processing equipment with stable performance and high precision, such as high-precision CNC machining centers, EDM machines, and laser processing machines. These equipment are equipped with advanced control systems and precise transmission systems, enabling high-precision processing and complex surface processing. At the same time, it is necessary to regularly maintain and service the equipment to ensure its stable and reliable performance, preventing processing quality degradation and production delays caused by equipment failures.

V. Strictly Controlling Quality and Conducting Comprehensive Inspections

Quality control and inspection are the solid lines of defense for ensuring the quality of tungsten carbide dies, throughout the entire die customization process. When customizing a tungsten carbide die, it is necessary to establish a comprehensive quality control system and conduct thorough inspections on the die.

Raw material inspection is the first line of defense in quality control. Conduct rigorous inspections on the purchased tungsten carbide raw materials, checking whether their chemical composition, physical properties, and metallographic structure meet requirements. Through testing methods such as spectral analysis, hardness testing, and metallographic inspection, ensure that the raw material quality is reliable, laying a solid foundation for high-quality die manufacturing.

In-process control is the core link for ensuring die quality. Strictly control each processing step during the processing process, formulate detailed processing technology procedures and quality control standards, and monitor and adjust processing parameters, tool wear, and processing dimensions in real-time. By using online inspection technologies and quality traceability systems, promptly identify and solve problems that arise during processing, ensuring that processing accuracy and quality meet requirements.

Finished product inspection is the final barrier before the die is put into use. Conduct comprehensive inspections on the processed dies, including dimensional accuracy, shape accuracy, positional accuracy, and surface quality. Use high-precision inspection equipment such as coordinate measuring machines, projectors, and roughness testers to accurately measure and evaluate various indicators of the die. Only dies that pass strict inspections can be put into use, ensuring that the die can meet actual production requirements.
