die tooling life refers to the total number of parts that can be processed by cemented carbide die tooling under the premise of ensuring the quality of product parts. It includes the service life after repeated grinding of the working surface and replacement of wearing parts, which refers to the natural life of the die tooling under the condition of no accident, that is, the life of the die tooling = the one-time life of the working surface x the number of grinding times x The number of replacements of wearing parts. The planned life of the die tooling is the total number of times the die tooling is produced, which is clearly defined in the die tooling planning stage. die tooling life is related to die tooling type and structure. It is a comprehensive reflection of cemented carbide die tooling data skills, die tooling planning and manufacturing skills, die tooling heat treatment skills, and die tooling maintenance level.
die tooling failure and cemented carbide die tooling factory damage. die tooling failure means that the die tooling is damaged and cannot be corrected and continues to produce qualified parts. die tooling damage refers to the size change or micro-cracks of the die tooling in the process of use, but the die tooling can continue to produce qualified parts. die tooling failure and die tooling damage are completely different concepts. Broadly speaking, die tooling failure means that a set of die tooling can no longer be used. In actual production, it mainly means that the die tooling cannot be corrected and reused. If the die tooling is damaged, it can be used continuously.
Different die tooling types, different products produced, and different ways of failure. For example, the forging die will fail due to the forging dimension does not meet the requirements or the forging die breaks, and the plastic die tooling that produces plastic parts with a bright surface will fail due to the increased surface roughness of the die tooling. Both cold and hot die tooling may be worn out due to wear. Invalidate. The basic failure modes of the die tooling include wear, fracture and cracking, fatigue and deformation, corrosion and so on.

Advantages of cemented carbide die tooling in practice:
Advantage 1: The friction coefficient is reduced, the surface hardness of the processing force is reduced, and the life of the die tooling is greatly extended to avoid the product fuzzing and strain, and the production quality is improved, eliminating the trouble of unloading, polishing and reloading the die tooling, and the forward power
Strength 2: In the process of die tooling application, early failure often occurs. The factors of failure are generally wear, corrosion, fusion, adhesion and so on. The problem is not only to delay the consumption cycle, but also to greatly increase the cost of consumption, and then affect the competitiveness of enterprises. To this end, the industry has successively introduced different treatment solutions, and the titanium-plated surface treatment technology is a favorite solution, which can most effectively deal with the above-mentioned problems. PVD coating technology can be widely used in all kinds of things, die tooling, mechanical parts, medical devices, etc. that cause failure due to wear, seizure, corrosion, adhesion, and fusion. In the meantime, failed products caused by wear (such as: blanking, cold heading, powder die toolinging, etc.) can have a lifespan of more than 5-8 times after coating; product or die tooling strain problems caused by seizure (such as: drawing die , Drawing dies, flanging dies, etc.), which can be basically processed after coating.
Strength 3: The microstructure of the TICN coating of fine and nano-particles has high toughness, high hardness, high oxidation resistance, and can end the extremely lubricated surface of frictionless chip removal, and then makes the excellent performance of the workpiece to be fully displayed. Compared with TIN coating treatment, the surface brightness is better, the friction coefficient is small, the hardness is high, and the oxidation resistance is strong.
Strength 4: For different die tooling (powder metallurgy die tooling, stamping die tooling, forming die tooling, drawing die tooling, forging die tooling and injection die tooling, etc.) and the selected coating process of the parts, the hardness, wear resistance, and resistance of the surface can be significantly improved Corrosion, heat resistance and smoothness, etc.; and can be easily removed, greatly improving the quality of die tooling and parts (such as surface roughness and accuracy, etc.) and service life, so that it can effectively play the potential of the product.
