EspañolMould manufacturing
Mould manufacturing in china has been greatly developed during the past 15 years. During these years, Chinese mould manufacturing has gathered a lot of experience and also improved the design mentalities.
Most of the Chinese mould manufacturers are in the shortage of management, quality mentality and machining process knowledge.this is the reason that why most of the mould manufacturing quality level in China can not be the same quality as Europe.
Mould manufacturing has 3 main points:
*Mould design ability and mould design mentality
*Machining process knowledges
*Quality controlling during the whole mould manufacturing proccessing
This is meaning that if based on the goodmould manufacturing equipments,moulds manufacturer need above mentioned 3 points to improve the mould manufacturing, otherwise, it is very difficult for all the Chinese mould manufacturers approach the same quality as European.
During the mould manufacturing, the 1st point is mould design, this is the 1st step. If the mould design was not correct or mistake, maybe this will cause all the efforts are useless. As because some of the mould design mistake will moulds scrapped, and some of the mistakes will increase a lot of make up jobs on the mould manufacturing, welding, structure changing…all these are hurting the moulds quality.
If the mould was perfectly designed while your machining quality can not arrive the mould cavities, cores or other components dimensions requirements, we also can not get a qualified mould. For example, CNC milling is precise, you can use a Taiwanese CNC milling machine to approach a tolerance with minu or plus 0.05mm. But if you can not use CNC milling machine well, you can never get such a tolerance during yourmould manufacturing, for example the tool wear will cuase the bigger tolerance, the steel block deforming will cuase the huge tolerance…For this reason,
we need the special controlling and treatment during the CNC milling, this we call it machining process… The CNC milling has special machining process, of course that EDM , wire cutting or lathing…all of them have their special processing.
The step by step quality controlling is most important during the whole mould manufacturing processing. As because one mistake will cause all the followed processing become wasted. The moulds manufacturer need to be sure that all the previous steps are correct. For this issue, we need be sure that none mistakes will be left to the next step.
