Precision Machining and Processing of Die Components
Die components or mold accessories refer to the parts or components of the mold tooling, It can also refer to the replaced components for maintenance of tooling after damage.Precision molds are generally composed of many parts, which can be divided into two categories: process parts and structural parts. The quality of process parts directly affect the mold tooling life. Most of the process in the current precision mold accessories are finished by many manufacturing process.
Precision machining process is related to the life of precision die and molding products.During the precision die parts processing stage, in addition to the selection of precision wire cutting, sinker E.D.M and other technological techniques, the other method is the precision grinding after in semi-finishing and heat treatment. So in the process of precision grinding stage, many technical parameters such as deformation, internal stress, shape service and scale precision need to be controlled.
In the actual production practice, the operation will face more difficulty.Following the decades years of precision machining experience,We start from mold finishing process by controlling each precision die components manufacturing. we can adapt the processing according to different mold components, material, shapes and different technical requirements.
After the optimize the processing process, we can achieve better processing function and economy ,it is the key for most precision die components processing enterprises. The processing process of precision machining components is generally as follows: rough machining – half finishing machining – (quenching, quenching and tempering) – precision grinding – electrical machining – fitter dressing – assembly processing
