Further Development of The Casting Mould, Hot Runner Technology
Ten years ago, precision casting mold generally
for 5 microns, is now up to 2-3 microns, 1 μm precision casting
mold forthcoming soon. With the improvement of component
miniaturization and precision requirement, some casting mould
machining precision requirement within 1 μm, which requires the
development of super finishing.
An increasingly large casting mold.
On the one hand is due to the increasingly large parts with
casting mold forming, on the other hand is due to the high
productivity requirements of a touch more cavity (some hundreds
of cavity has amounted to a touch now).
Expand the application of hot runner technology
Due to the hot runner technology of casting mould can improve
production efficiency and quality of parts, and can greatly save
parts of raw materials. Therefore, by the rapid development of
hot runner technology applications in foreign countries, many of
the plastic casting mold factory production, more than 50% of
the casting mould with hot runner technology, even more than
80%, the effect is very obvious. Hot runner at home have also
been used in the production, some enterprise utilization rate
reached 20% ~ 30%.
Modern casting mould with the traditional casting mould is
different, it is not only the shape and structure is complex,
and the technical requirements higher, with the traditional
casting mould manufacturing methods obviously difficult to
manufacture, must use modern science and technology development,
USES the advanced manufacturing technology, to achieve technical
requirements. The current development characteristics of the
whole industrial production is the product varieties, updated
quickly, the market competition is intense. In order to adapt to
the market of casting mould making short delivery time, high
precision, low cost, the urgent request of casting molds will
have the following development trends.
