Deep Drawing Press Selection Guide for Shell ComponentsUpdate：2026-10-26     Hits：18

Deep-drawn shell components are everywhere: stainless steel cookware liners, EV battery housings, sensor cans, automotive shells, pressure vessels and electronic enclosures. Unlike simple blanking or bending, shell deep drawing demands stable, tunable force, controlled material flow and consistent blank holder pressure. A poorly matched press will create recurring defects — wrinkling, wall thinning, tearing, uneven shell walls and high scrap rates — even with well-made drawing dies.
At Goodsjack Hydraulic Machinery, we have spent over 27 years building presses for metal forming applications across the globe. This guide distills what we have learned about selecting a deep drawing press specifically for shell-type components—whether you are producing cookware, lighting housings, motor covers, or similar drawn parts.

The Three Selection Criteria That Actually Matter
1. Structure: Four-Column vs. Frame-Type
For shell components, the press structure determines how consistently the ram travels through the stroke. Any lateral deflection under load translates directly into uneven die clearance—and uneven wall thickness in the finished shell.
Four-column presses distribute load symmetrically across four guide pillars. Goodsjack’s four-column deep drawing models are specifically designed for “tableware, kitchenware, metal cover of electric motor, household appliances and lighting ware”—all shell-type products. The four-column configuration provides the rigidity needed when the blank holding force is applied simultaneously with the drawing force.
Frame-type presses offer excellent rigidity as well, but they are often better suited for shallower drawing or combined stamping operations. If your shell requires deep draws with significant material flow, the four-column deep drawing platform is the more direct match.

2. Blank Holding Control: The Difference Between Success and Scrap
In deep drawing, the blank holder does more than hold. It controls the rate at which material enters the die. Too little force, and the flange wrinkles. Too much, and the material cannot flow—causing it to tear at the punch nose.
This is where the specification of the blank holding cylinder matters as much as the main cylinder. Goodsjack’s DSFS series offers blank holding capacities that scale with the main tonnage: a 160-ton main cylinder pairs with a 60-ton blank holder, while a 350-ton main cylinder pairs with a 150-ton blank holder. The ratio is not arbitrary—it reflects the holding force required to keep the flange stable while the punch drives material into the cavity.
For shell components with demanding geometries, we also recommend presses equipped with multi-stage speed control on the drawing stroke. The DSFS series allows drawing speeds as low as 14–18 mm/s on larger models, giving the material time to flow rather than being forced.

3. Stroke and Open Height: Accommodating the Draw Depth
A hydraulic press can theoretically draw to a depth equal to its stroke length, because it delivers full tonnage at any point in the stroke and can move as slowly as the material requires. For shell components, this means the press stroke must exceed the draw depth with margin for loading, unloading, and die height.
Goodsjack’s DSFS models offer stroke lengths from 350 mm on smaller units up to 700 mm on the 600-ton model. The open height and working table dimensions must also be checked against your die set. A deep shell often requires a taller die assembly, and the press’s open height must accommodate both the die and the blank placement before the stroke begins.

A Practical Note on Tonnage
Many buyers default to “more tonnage is safer.” That instinct can lead to overspending and a press that is harder to control at the low end of its range.
For shell components, start with the material and wall thickness. A 2 mm stainless steel shell with a 200 mm diameter and moderate draw depth may require substantially more force than a similar aluminum component, because stainless steel work-hardens rapidly and resists flow. The press must have enough tonnage to complete the draw without stalling mid-stroke, but it must also be controllable at the slower speeds deep drawing demands.
Goodsjack’s application engineers routinely size presses from customer drawings and material specifications rather than from tonnage alone. The DKHS range from 50 to 800 tons covers the majority of shell applications in cookware, lighting, and appliance components, but the specific model should be confirmed against the actual forming force calculation.

What to Send Us for a Precise Recommendation
If you are evaluating a deep drawing press for shell production, the most useful information you can provide is:
• Shell drawing: outer diameter, total depth, and any flanges or stepped features
• Material grade and thickness: stainless steel, cold-rolled steel, aluminum, or copper
• Production requirement: strokes per minute or daily output target
• Die dimensions: if already designed, the shut height and die footprint
With these details, Goodsjack can confirm the appropriate DSFS model, blank holding capacity, and speed profile for your application. Our four-column deep drawing presses are built in-house with imported hydraulic components from Bosch-Rexroth and other European, American, and Japanese suppliers, and every machine is backed by ISO 9001:2015 and CE certification.
The right press for shell components is the one that controls material flow, not just force. Choose accordingly.
