China Plastic Injection Molding Companies

China plastic injection molding companies now are facing the heavy pressure, it is because of the currency exchange rate, inflation and heavy competitive of domestic China injection molding company. Below is the detail reason for the heavy pressure of China plastic injection molding company

The currency exchange rate of RMB: USD from 10 years ago 9.5 to now 6.3-6.5, this reduced Mold manufacturer China Companies profit become less & less.
The inflation caused the Mold manufacturer China Companies to need to pay more material cost such as mould steel and other material. Also need to pay a much higher salary, from 2009 to 2011, the general salary has been 40% increased, and not increase more every year
There are more than 10000 big or small china plastic injection molding companies, most of them the tooling ranges are the same. For this reason, when need any purchase order, they competed with each other by the mould price, seldom of china plastic injection molding companies are competitive by quality. This is caused the price goes down and down. Also because the international economic situation is not so good, most of the mould investors, they cut the mould price until the red line price.

Mold Manufacturer China

Due to the above points, we are thinking that how could mold manufacturer China companies survival for a longer time while not like most of the European mould makers. As we know 30 years ago, many people went to German, Italy, or Portugal to order moulds, 20 years ago, people visit China Taiwan area to order the moulds, from 10 years ago, people come to Chinese mainland mould makers to custom molds. Now China plastic injection molding companies are thinking how long time it will last for people ordering moulds from China? It is a serious question, really, we are facing some pressure.

Are there any new ways for China injection molding companies?
Is there any new technologies for mould making can be innovated by Mold Manufacturer China Company?
Is there will be any revolutionary for plastic molding technologies?

I think nothing is impossible, for example, if we can use new technology to melt the good quality steel, then use the + pole for core and – pole for the cavity to make the cavities and cores by the very fast and precise way. By these technologies plus some high tech steel treatment way, Chinese mould maker can make a mould within 2 or 3 days. That is really a funny thing.
