Concepts of Squeeze Casting
|
It is also called pressure
solidify.
This is high pressure forming
solidify manufacture which applies machinery high pressure
with oil pressure press into melting bath of mold frame
or into exact mold cavity which is separate way after the
late replenishment to reactor with pressure.
This applies high pressure
to the solidifying process that liquid metal is turning
its capacity from liquid to solid, so that controls the
defect of casting and makes high quality casting products
which are improved at resist pressure and strength.

The application of Squeeze Casting
|
1. The internal pressure parts
which need Gas or oil replenishment.
2. The parts that need high intensity (strength)
3. The parts that use FRM
4. The parts that use Insert

Properties and merit of Squeeze Casting
|
1. The remove ability
for gas bubble
2. Near-Net-Shape
: The minimum deduction of machining area (0.3~0.5mm)
3. The improvement of mechanical characteristic (pressure
and strength)
4. The high quality of fatigue strength and percussion strength
for functional parts
5. The ability of casting heating treatment
6. We can make molds that can be welded.
7. It has high adhering rate with other materials.(combination
or any alloy can be molded)
