Simple Machining Of Large Complex Molds

- Aug 17, 2018-

In order to obtain the highest possible surface quality during large mold machining, we need to select the right machine and configure the necessary tools. Only in this way can we reduce the EDM's subsequent processing time and the manual grinding time of the fitter. With the rapid development of the automotive industry, the demand for various large and high decorative molds for automobiles is growing rapidly.


Under the outdated machining technology, the machine feed rate is slow, the operator needs to perform multiple debugging and clamping on the workpiece, and it takes several hours of manual polishing, so the processing cycle is very long. Therefore, more advanced processing techniques must be sought to make the processing of large molds as easy as machining small molds.


The main problems in large mold machining:

Huge size and weight

When machining large molds, how to deal with their own huge size and weight is a major challenge for machining companies. The processing of large molds often requires a large amount of labor, special equipment and multiple debugging and clamping, and the processing accuracy is also affected by many potential factors and is not easy to guarantee.


Acquisition cost problem

The biggest cost directly related to the machining and production of various large-scale molds is the purchase cost of the machine tool. Machine tools capable of producing large molds are quite expensive, especially in complex process arrangements where multiple machines are required to complete the entire process from mold roughing to finishing. Such early high input costs are also the biggest obstacle for many companies to enter this market. From this, we can see that if the roughing and finishing of large molds can be realized on a suitable machine tool, even if it is only necessary to debug the clamping, many problems will be solved and the machining accuracy can be guaranteed.
