What is the difference of Silicone Hydraulic Mould and Silicone Injection Mould ?
Hydraulic Mould injection molding
In the hydraulic molding process, the mixed silicone is filled into an open mold. For a core and
cavity mold, the cavityside is usually filled with excess material. Once filled, the two halves are then
uniformly compressed under hot platens. After a certain amount of curing time, the two halves are
either manually or mechanically opened. The final part is removed after excess material is detached.
In the injection molding process, the A and B component materials are mixed from the mixing unit,
and immediately travel through the cool barrel. The mixed material is then injected in a hot closed
mold. After the curing and mold-open phase, the final part is removed from the mold.
The main different include below:
A. The mould material is different.
Injection mould material is expensive than silicone Hydraulic mould material.
B. Different structure design and Product forming method
C. Different Silicone material
Hydraulic Mould product is made of Solid silicone.
Injection Mould product is made of Liquid food grade silicone.
