The Benefits of Deep Draw Stamping

Deep draw stamping is optimal for products that require water-tight or air-tightness, (there are no seams), significant strength, and minimal weight. Often, it is the most effective way to form products that have unconventional or difficult geometries. In terms of production logistics, deep draw stamping provides many benefits:

• Increased productivity

Draw speeds are limited only by the contact velocity required by the material. If multiple draws are required to produce the finished draw, they can be performed simultaneously in stations of a transfer or progressive die, optimizing cycle times. If you have large-volume needs and want to keep costs down, these rapid cycle times are an efficient way to go.

• Lower initial costs

Deep draw metal stamping provides cost-effective production of complex components with reduced material waste and enhanced efficiencies. Tooling costs are lower, typically requiring only one set of durable and renewable tool steel or carbide dies, minimizing the need for re-tooling.

• High Precision

The controlled deformation of metal sheets ensures consistent and accurate part dimensions, meeting the most stringent quality requirements.

• Exceptionally strong parts

Deep draw stamped parts are stronger and more durable due to cold-working, which improves mechanical properties and resistance to wear, corrosion, and fatigue. The process maintains an elongated and cohesive grain structure throughout the part, ensuring strength, while also increasing hardness and tensile strength.

• Metal diversity

A wide range of metals can be deep drawn, providing a number of manufacturing options. The most common metals include mild steel, stainless steel, aluminum, copper, and brass. A knowledgeable stamper should be able to offer assistance in choosing the best material or alloy for your application.

Types of Deep Drawing

Deep drawing comes in various types, each with its benefits and material suitability:
Conventional Deep Drawing: Involves pushing a flat metal sheet into a die cavity using a punch, forming the desired shape seamlessly.
Progressive Deep Drawing: Utilizes multiple dies to gradually form the part as the blank passes through different stations, suitable for complex shapes requiring various forming steps.
Tandem Deep Drawing: Similar to progressive but uses multiple blanks simultaneously, allowing for parallel production and increased output.
Reverse Deep Drawing: Also known as negative drawing, involves drawing a pre-formed shell or cup into a die to create deeper components with smaller openings, ideal for containers and housings.
Compound Deep Drawing: Simultaneously uses different dies and punches to create parts with intricate designs.
Hydroforming: Specialized method for creating deep-formed metal stampings, particularly useful for unconventional shapes found in structural and automotive applications.
