APG HAS MANY PROJECTS THAT INVOLVE NEW PLASTIC PARTS AND WE ALWAYS STRUGGLE WITH JUSTIFYING CONVENTIONAL TOOLING FOR INJECTION MOLDING BECAUSE OUR VOLUMES ARE LOW FOR 2-3 YEARS WHILE WE TRY TO "SEED" THE MARKET.

 

LET ME CLARIFY THE VOLUMES; I AM TALKING ABOUT MAYBE 2000 PARTS PER YEAR AND SOMETIMES MUCH LESS.

 

WE TYPICALLY USE THE SLA PROCESS TO VERIFY THE DESIGN AND THEN MAKE RUBBER MOLDS TO CAST POLYURETHANE PARTS FOR THE FIRST 10 OR SO PROTOTYPES FOR OUR CSUTOMERS TO EVALUATE. WE USE THE CAST POLYURETHANE PARTS FOR ANY SUBSEQUENT PROTOTYPES UP TO MAYBE 50. WHEN WE NEED MORE THAN THIS VOLUME THE CASTING PROCESS BREAKS DONE BECAUSE OF THE LONG PROCESSING TIME FOR THE CASTING PROCESS. USUALLY 2 PARTS PER DAY UNLESS WE HAVE MULTIPLE RUBBER MOLDS THEN WE CAN MAKE 4 PARTS PER DAY. THIS IS NOT ADEQUATE WHEN WE NEED A FEW HUNDRED PARTS IN A SHORT TIME.

 

DOES ANYONE HAVE SIMILAR PROBLEMS AND HOW DO THEY SOLVE THEM?

 

WE HAVE HAD PARTS QUOTED FROM QUICKPARTS AND OTHER ONLINE SUPPLIERS BUT WE ARE NOT SEEING MUCH COST SAVINGS OVER CONVENTIONAL INJECTION MOLD TOOLING. HELP!!!!
