Deep Draw & Deep Drawing
Deep Drawing / Deep Draw is the process of forming a part from metal sheet stock, commonly referred to as a blank, around a punch as it is drawn through a die. The edges of the metal blank are restrained by a “blank holder" or a sleeve in the case of a redraw.
Since the state of the art does not allow us to go as deep as we might need to go in one draw operation we can institute a redraw, whereby we reduce the diameter and increase the height of a previously drawn shell.
There are many shapes that can be made through deep drawing / deep draw such as cups, pans, cylinders, domes & hemispheres, as well as irregular shaped products.
The terms Hydroform / Hydroforming and Deep Draw / Deep Drawing are many times used interchangeably, with Hydroform / Hydroforming now being the industry "buzz word" for metal forming. Both process offer their own unique advantages to metal forming. The following are some design considerations (criteria) that are taken into account when determining the process to be used for a specific part.
Metal Forming and Manufacturing Capabilities
Our capabilities include deep drawing in diameter ranging from 1/2 inch to 24 inch, depth up to 24 inches, & blank size up to 48 inches. Hydro forming up to 15 inches diameter, 10 inches depth, & blank diameter up to 21 inches.
Deep Draw / Deep Drawing Considerations
- Common shapes for Hydroform / Hydroforming parts are domes and concave/convex/dished surfaces, whereas Deep Drawn / Deep Draw shapes are more commonly cans, boxes, and bottles, as well as irregular shaped products.
- Hydroforming / Hydroform can attain up to a 60% reduction on a metal blank, where Deep Drawing / Deep Draw only a 43% reduction. However, multiple draws are not possible on a hydroform / Hydroforming part, whereas numerous re-draws can be performed on a deep drawn part to attain a desired depth.
- Tooling for a Hydroform / Hydroforming part is typically less expensive than for a Deep Drawn / Deep Drawing part, since only a punch and ring are required. Deep Drawing / Deep Draw requires a punch, die and blank holder. If the part is conducive to hydroforming and relatively small quantities are desired, hydroforming / Hydroform provides a cost effective solution to forming the part.
Quality System (Conforms to MIL-I-45208)
With our MIL-Grade Quality System 
, our commercial customers enjoy the same critical quality control standards that have allowed us to deliver Defense Department contracted product for many years. Amalco employs the latest technologies in its QC inspection processes, and maintains its own QC Manual focused on a goal of "Zero Defects on All Products Produced".
Deep Drawn Aluminum Boxes & Covers
Aluminum boxes and covers manufactured to your specifications, including custom designs, sizes, and configurations. We maintain stock tooling to manufacture hundreds of typical sizes and configurations of rectangular aluminum boxes, enclosures, and covers.
Use our convenient Aluminum Boxes and Covers Buyer's Guide to specify and order your aluminum parts by outside width, outside length, maximum overall height, inside corner radius, inside bottom radius, thickness, and cover fitting requirements. Government certifications on specifications are available upon request where applicable.
Deep Drawn Cans
Deep drawing is used to produce seamless metal enclosures such as cans, boxes, and bottles, as well as irregular shaped products. Deep drawing requires tooling, including a punch, die, and blank holder. A punch is pressed against a material blank and the material is drawn through the die to form the desired shape.
Deep drawing can achieve up to 43% reduction on a metal blank, and multiple successive deep draws can be used to achieve part size or shape requirements. A variety of metals can be deep drawn, including aluminum, stainless steel, aluminized steel, cold rolled steel, brass, bronze, cupro nickel, nickel, and titanium.
Use our convenient Aluminum Cans Buyer's Guide to specify and order your aluminum parts by outside diameter, maximum overall height, inside radius, annd blank thickness requirements.
ARINC Cans - Square Aluminum Enclosures for Aircraft Electronic Instrumentation
ARINC (Aeronautical Radio, Incorporated) was chartered by the US Government (Federal Radio Commission, now Federal Communications Commission) to coordinate non-governmental radio communications. ARINC developed standards for interchangeable trays and boxes used to enclose standard line-replaceable units (like radios) in aircraft (known as ARINC electronics enclosures, or ARIN cans). ARINC square avionics instrumentation mounts are designed to be light weight, and to enable the rapid exchange of on board electronics components without complex fasteners, connectors, or the need for special tools or test equipment.
Amalco delivers aluminum deep drawn aircraft instrument cases and electronics enclosures in both standard and special (custom) designs and sizes, meeting dimensional requirements for ARINC Specification Number 408A . The deep drawn process ensures exact tolerances, meeting ARINC requirements and your specifications.
Amalco provides complete in-house facilities for fabrication of ARINC cans to your specifications, made from 0.050" thick 3003-0 Aluminum (6061 optional). Piercing, attachments, and other secondary operations are performed in-house, saving you paperwork and procurement processing time (single authorization) while ensuring strict quality control from raw material through finished product. Brazed assemblies, dip-brazing and finishing (including alodine or anodize and paint) are also performed in-house at Amalco's Mountainside, New Jersey facility. Contact Amalco for your ARINC cans and mounts.
Use our convenient ARINC Brochure to specify and order your aluminum parts by alloy and reference number.

Why do we choose Amalco?
“Amalco offers a 'one-stop shop'. In the past our combustion cones were shipped back and forth between several subcontractors to have them perform different production steps. Amalco performs each of these operations at one facility; thereby, reducing our cone supplier base from three to one. Now, we coordinate inventory and communications with only one cone supplier, which saves us invaluable time and resources.”
