Vacuum Casting Mold,Vacuum Casting Service
The complex mold is to use the original sample plate to make a silicone mold under
vacuum condition, and to pour the PU material under vacuum, thereby cloning the
same copy of the original plate, which is higher in temperature resistance and
hardness than the original plate.
If the customer asks to do a few sets or dozens of sets, it is suitable to use
this method, which greatly reduces the cost. The product model of vacuum multi-
module has a certain proportion of shrinkage. The cost of vacuum replicating
product model is generally lower than that of CNC. That is, the price of CNC
processing multiple sets of samples is lower than the price of vacuum-module after
CNC machining 1 set (right) Except when there are special requirements for the
sample material produced by the complex mold);
The composite materials are: ordinary PU: brittle, tough; transparent PU: good raw
materials, but the price is the most expensive; rubber-like PU; 8400 soft rubber.

The technique of vacuum complex molding can be used for two purposes:
1. Produce small batches of product samples;
2. Change the material; the template carved from gypsum sludge can be changed by
the complex mold to the PU or POLY material which is easy to be processed later,
or the ABS material can be changed to a material with special requirements (such
as: requiring transparent, high temperature resistance) , high strength, or rubber
properties, etc.).
