Investment casting process typically includes the following steps:
Die Manufacturing: Utilizing advanced CAD/CAM facilities to create precise dies (patterns/tools).
Wax Pattern Production: Injecting wax into the dies to produce accurate wax patterns, which are then thoroughly inspected for dimensional accuracy.
Assembly: Attaching the wax patterns to a central wax runner system to form a tree or cluster.
Ceramic Shell Formation: Coating the wax assembly with multiple layers of ceramic material in a controlled environment to achieve the desired thickness and strength.
Shell Firing: Baking the ceramic molds at high temperatures to enhance their strength and prepare them for metal pouring.
Metal Pouring: Pouring molten metal into the preheated ceramic molds.
Cooling: Allowing the metal to solidify within the molds.
Shell Removal: Breaking away the ceramic shell to reveal the metal castings.
Finishing: Performing processes such as gate cutting, grinding, sandblasting, and deburring to achieve the final product specifications.
Heat Treatment: Applying heat treatment as per material specifications to achieve desired mechanical properties.
Inspection: Conducting thorough inspections, including visual and dimensional checks, to ensure quality standards are met.
Machining and Surface Treatment: Providing additional services like machining, passivation, electro-polishing, blackening, powder coating, shot blasting, or glass bead blasting as required.
