requirement? If not, you could look at using External Gas Molding ( EGM)
, where nitrogen gas is applied in the form of a pressure cushion over
the whole ( or part) of the surface area. This can have the effect of
distributing a packing pressure evenly across the whole plastic part and
compensating for material shrinkage with gas. It can also reduce the
injection molding cycle time, reduce material and reduce the clamp force
requirement ( possibly machine size too) . Finally, EGM can produce
excellent sink- free surface quality on the ' A' side and greatly
increase design freedom as far as ribs and bosses are concerned - you
can introduce injection mold ribs where they would otherwise be
unacceptable and is possible to reduce wall thickness of the part and/
or increase wall: rib thickness ratio to 1: 1. Adjusting an existing
plastic injection mold for EGM can be a difficult, if you have a number
of moving parts in the injection mold.

- Business Description: Our company is situated in Central Europe. There are many costumers that
are asking for our offers for plastic injection mold details that they
use to buy from China. The reasons are the higher prices and quantity
China policy, higher tech & Quality production. Side effect, Higher Costing. Actually, it is common process of every industrial country. However, the growing of China is much faster than others.
I worked with a Chinese injection mold shop importing their tools to Japanese transplant companies here in the USA. They offered three levels of tooling: Japanese (similar to American, Canadian and German), then Korean, finally Chinese. They had facilities or partners in those countries so they could control the manufacturing process thus the quality.
