Deep Draw Process, Features & Specs
Multiple Complex Steps
in One Machine
Deep drawing is a cost effective, high-quality method of fabricating metal components. It can replace other more costly forms of stamping, machining, tubing and casting, which require multi-process machining and increased material utilization. The deep drawing process saves you time and money through the efficient use of material and the ability to perform multiple, complex steps in one machine and in one process.
From Flat Blank to
Finished Product
The deep drawing process forms metal into complex shapes not possible with other forms of stamping. The process is accomplished by a transfer press, in which each station operates independently from the others. The first operation in a transfer press creates a flat blank, which is carried through as many as twelve or more operations, depending on the complexity of the part. The blank diameter is formed into the completed part through a series of draws, piercings, clippings, imprintings, and attachments to form threads or beads, depending on the part specifications. The blank is reduced through a series of draws in the multi-station press in order to facilitate its form, avoid material deformation, and end in a finished part meeting all the print specifications.
A Precision, Streamlined Solution to
Your Complex Specifications
The unique ability of the deep draw process to complete part production in one machine provides the answer to some of your most complex design specifications. Let us help you find solutions to your design needs by offering these production capabilities:
♦ Rolled threads
♦ Side wall piercings and lancings
♦ Dimensioned dimples and spherical shapes
♦ Fold overs, angled edges and chamfers
♦ Tabs, straight or bent in the side, bottom, or top
♦ Formed grooves
♦ Beads: round, square or shaped
♦ Smooth finishes
♦ Embossed markings: weekly and daily dates, patent numbers and logos
Technical Specifications of Deep Drawn Metal Parts
We continually expand our deep draw material selection based on our customers’ needs. All materials utilized must possess the chemical and mechanical properties that facilitate deep drawing and forming.
We work with various carbon and stainless steels, brass, copper, aluminum and specialty pre-plated steels. Each of these materials has different properties that require a “fine-tuning” of the deep drawn process to avoid irregularities and to achieve the proper geometry of the finished part.
We consistently work with tolerance of .001 or less, which provides a deep draw forming consistency and less dimensional variation. All materials are cold rolled sheet, rerolled to the required gage and slit to the required width. A common reference to deep draw-capable material is “DDQ” or deep draw quality.
The PMP technical team of engineers and tool makers have the experience and expertise to customize the deep drawn transfer press settings, which includes pressure, press speeds, clearances and tool lubrication based on the material’s characteristics.
Our Engineering team will work closely with you to create the part that matches your exact specifications. Contact us for a quote or book a meeting today!
