The service life of non-standard mold accessories is affected by many factors, some of which play a key role.
First, the choice of materials is crucial. Different materials have different mechanical properties, wear resistance, and corrosion resistance. For example, if a material with lower hardness is used to make accessories that are subjected to greater pressure and friction, its surface may wear faster, thus shortening the service life. If the corrosion resistance of the material is poor, it may rust when it comes into contact with some corrosive substances, resulting in a decrease in the performance of the accessories. The appropriate material should be determined according to the specific use environment and functional requirements of the accessories to ensure that it can maintain a good condition during the working process.
Machining accuracy is also an important influencing factor. If there is a deviation in the machining size of the accessories, it may lead to improper assembly and generate additional stress and friction during the operation of the mold. For example, inaccurate hole size may make the matching clearance between the shaft and the hole unreasonable, either too loose to cause shaking and increase wear; or too tight to make assembly difficult and generate greater stress concentration during operation. High-precision machining can ensure good fit between accessories, reduce unnecessary wear and energy loss, and thus extend service life.
The working conditions of the mold also have a great impact on the life of non-standard mold accessories. The working temperature, pressure and working frequency will affect the performance changes of accessories. In a high temperature environment, the strength of the material may be reduced, and frequent high pressure and high frequency use will accelerate the fatigue damage of accessories. For example, in some high-speed stamping dies, accessories need to withstand rapid impact and friction. If the working conditions are bad and no proper protective measures are taken, their life will be greatly shortened.
In addition, maintenance and care should not be ignored. Regular cleaning, lubrication and inspection can timely detect potential problems of accessories, such as tiny cracks or signs of wear on the surface. By dealing with these problems in a timely manner, the service life of accessories can be effectively extended. If maintenance is neglected, some minor problems may gradually develop into serious damage, eventually leading to premature failure of accessories. In summary, to extend the service life of non-standard mold accessories, it is necessary to comprehensively consider factors such as materials, processing accuracy, working conditions and maintenance.
