INVESTMENT CASTING

SEYBERT CASTINGS UTILIZES A CUSTOM INVESTMENT CASTING PROCESS. IT IS WELL SUITED FOR SMALL, INTRICATE ZINC ALLOY AND ALUMINUM ALLOY CASTINGS, AS WELL AS MEDIUM SIZED PARTS. IDEAL QUANTITIES RANGE FROM 1 TO THOUSANDS OF PARTS.

AS WITH ANY TRADITIONAL INVESTMENT CASTING PROCESS, BURNOUT PATTERNS ARE USED. OUR BURNOUT PATTERN BUILDING PROCESSES CAN BE SUMMARIZED INTO TWO GENERAL CATEGORIES.

WAX MOLDING - SEYBERT MOLDS WAX PATTERNS IN RUBBER TOOLING OR ALUMINUM TOOLING.

RAPID PROTOTYPE BURNOUT PATTERNS - PRODUCED FROM HIGHLY TOLERANCED WAX AND THERMOPLASTIC RAPID PROTOTYPE BURNOUT PATTERNS ON 3D PRINTERS DIRECTLY FROM 3D FILES.

 

EACH OF THE BURNOUT PATTERN TYPES HAVE ADVANTAGES AND DISADVANTAGES THAT NEED TO BE CONSIDERED. OUR CUSTOMERS RELY ON US TO DETERMINE AND EXPLAIN TO THEM OUR RECOMMENDED PATTERN AND MOLD BUILDING TECHNOLOGY FOR THEIR APPLICATION.
