CHEEK TRANSFER PRESS TECHNOLOGY
Over 60 years of experience in precision deep draw stamping.
A transfer press typically forms components that have a cupped shape. A typical cup-shaped part manufactured using a transfer press has a length-to-diameter ratio of 1:1 or greater. During transfer press stamping, we feed a coil sheet material into a press and create a blank by cutting the material from a coil strip.
This blank is then punched to create the first cup. Typical blank diameter to cup diameter reduction is 40%. Mechanical fingers transfer the cups to one or more subsequent draw stations where diameter reductions continue at an approximately 20% rate, creating the rough final shape. Finally, we transfer the part to additional stations to establish critical diameters and lengths, steps, features and forms.
Additional stations can customize features such as side piercing, bottom piercing, beading, bulging, coining, curling, extruding, ironing / wall thinning, necking, notching, rib forming, stamping, marking, threading and others.
Cheek Engineering has developed its own line of transfer presses, with a modular die and punch setup, allowing great flexibility in the press setup. The modular concept allows to interchange single steps of the stamping process, which results in very cost efficient tooling and parts variant creations. Producing parts in a transfer press enables greater length-to-diameter ratios and often utilizes less material, making your parts more cost effective.
Cheek Engineerings' different transfer presses with tonnage ranging from 80 to 150 tons, which enables us to match your part to the ideal transfer press based on initial blank size and part length.
We also can customize part production according to the number of stations required to deep draw the part, tonnage required, press speed (strokes per minute) and auxiliary equipment capabilities.
