Custom Metal Stamping in a Transfer Press
Trans-Matic has 110 different transfer presses with tonnage ranging from 5-600 tons. This range 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), machine energy and auxiliary equipment capabilities. Producing parts in a transfer press enables greater length-to-diameter ratios and often utilizes less material, making your parts more cost effective.
Trans-Matic offers deep drawn metal stampings utilizing state of the art transfer press technology to maximize efficiency. We match each deep drawn component with the ideal manufacturing process to give our customers the highest quality parts at the lowest cost.

About Transfer Press 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 pushed, or transferred, to the next station to create the 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 leak testing. For more information on additional in-press stations, read about our deep drawing process.
Transfer Presses vs. Progressive Die Presses
One of the key differences between creating metal stampings on a transfer press versus a progressive die press is the creation of the blank (relieving the material from the coil strip). Progressive die presses are mainly used for stampings where the length to diameter ratio is low and part side features are not required.
In general, a progressive die press serves well for bending, cutting and piercing. Due to the relieving of the material, a transfer press will allow the material to flow between the punch and die, thus allowing for greater length to diameter ratios.
A transfer press allows more flexibility, making it a better option for parts that require special features. Finally, in most cases, a transfer press utilizes less material than a progressive die press because a carry web is not required to produce the part.
Transfer Press Types
Transfer presses come in several forms from renowned press builders such as Aida, Chin Fong, Komatsu, Manzoni Minster, Osawa, Platarg, Seyi, and US Baird, among others.
Trans-Matic uses two main types of transfer press: ICOP, or individually cam operated plunger presses, and solid bed “die set” style presses. The motion of an ICOP transfer press is much the same as that of a gasoline engine. A rotating shaft with cam lobes drives the movement of each press station individually. A die set transfer press has a solid flat surface that creates the press motion and activates all press stations at the same time.
These transfer presses also come in various sizes with various capabilities. At Trans-Matic, we understand the critical process of matching the right press to the part for production. Trans-Matic has a wide range of transfer press capabilities that allow us to match the optimum press to your part.
