MAGNESIUM Molding Flasks
MAGNESIUM SPREADLOCK FLASKS
Spreadlock Flasks are constructed of magnesium. By using this metal, our standard Flask is designed for heavy duty work and is comparable in weight to a medium weight flask constructed from aluminum. Magnesium is well suited for Flask construction as it is one-third lighter in weight, and at the same time, approximately twice the tensile strength of aluminum.
Opening corners are operated with hardened cams with an aluminum lever. Replaceable rubber inserts seal the corner gaps, thus preventing sand from lodging in the corners.
Male and female stops are inserted above and below the cams, giving added strength to open corners and thereby allowing the Flask to maintain perfect alignment indefinitely.
All Fremont Flasks are available in three models
MAGNESIUM “1/2 A” LIGHT-WEIGHT FLASK
DESCRIPTION
The lightest version of the Fremont Flask Company’s iconic Spreadlock flask, the “1/2 A” has solved many problems where weight has become a conscious factor in molding. It features 1″ flanges with overall lighter construction. We have done this without sacrificing the strength of the flask. All custom specifications and options remain the same to ensure continuity.

MAGNESIUM “A” Standard-WEIGHT FLASK
DESCRIPTION
The standard Model “A” Fremont Flask is designed for all types of machine production jobs and can also be handled on a bench.
One of the outstanding features of these Flasks is the 1” Round Groovelock Pin and guide which is standard equipment. However, Flasks can be furnished with any other type of pin and guide which a customer may prefer. The method used to attach the Groovelock Pin to the drag, guarantees perfect alignment indefinitely, under normal working conditions. The only maintenance on this type of pin and guide is an occasional adjustment of the guide to take up any slack caused by wear.
All Spreadlock Flasks are jig and fixture drilled and machined. End or side castings are easily replaced. Particular attention is called to the sturdy construction of our tight corners. These corners are assembled by inserting three No. 42 dowel sleeves through which 5/16” cap screws are inserted.
