I’m very satisfi ed


with my long-term print advertising program in MCDP—it’s the only advertising I do. It gives me great visibility and name recognition, both with existing customers and with new ones. And the steady fl ow of new business it brings in easily justifi es the investment.

Many of the principles of inspecting fl asks on automatic horizontal green sand molding lines can be applied to maintaining manual molding lines using fl asks, as well.


casting quality: pattern engagement, pattern strip-off/ disengagement, strike-off, roll-over, drag set-on to pallet car (when applicable), drag positioning for core- setting, sprue drilling (when applicable), mold closing, mold clamping (when applicable), cope flask weight set-on (when applicable) and flask cleaning station.


• Gather only data critical for making a good mold and casting, such as surfaces used in pattern set-on and sur- faces used in mold closing. This data will be different for each metalcasting facility.


• Check flask components on a regular basis. Gaging and recording data for pins, bushings, bumpers, hooks and other parts is a critical part of controlling casting scrap attributed to worn flasks. Component life correlates directly to flask life and serviceability. Worn flasks consume hardware, (e.g. pins and bushings), at a higher rate than flasks maintained within dimensional specification.

At left, inspectors check the interior fl ask wall length with a quick gage and level. For checking fl ask height and parallelism, a go-gage is used, at right. Inner wall length, height and parallelism are just some of the mea- surements that should be checked during fl ask inspection. Checking fl asks on a regular basis is important to assure a quality casting.
