The Investment Casting is an engineering method that
can make the most similar figure of targeted products, and as a result,
the whole production cost can be decreased.
Making Die for Wax pattern injection.
Design the locations of gate & feeder.
Injection type ; Automatic, semi-auto, & plastic Inj.
M/C.
Setting the injected wax patterns on the fixtures.
Assembly the patterns on drum.
The patterns are attached to the drum for making a set-up cluster.
The assembled mold is coated with a fine grain ceramic slurry
using a specially designed vacuum machine.
To insure a uniform coating, automatically lowered & rotated
into slurry.
Using a fluidized bed, multiple layers of refractory grain
stucco are added for reinforcement.
The molds are dried under controlled condition.
Autoclaving extracts the pattern wax.
Recovered materials are processed for reuse.
The mold is prefired & cured to exact casting temperature.
Preheated mold is placed in a special vacuum casting chamber.
Molten metal is cast into the mold using vacuum assist.
Using the Mechanical vibration process to removal the refractory.
Theses techniques depend on the state of clusters.
After cooling, the parts are cut from the cluster with cut-off
wheel.
Using the mechanical cut M/C, & plasma cut process.
The castings are grounded smooth for grinding the gate.
And then, Sand blasting the castings to clean the surface.
Correcting the bended castings with static Press M/C.
Using the fixture by each part.
Castings are sent to inspection after the gauge check
