Clarifying Elements to the Deep Draw Design Process – The Draw Ratio When it comes to tool design, the most important formula is The Draw Ratio, also known as Limiting Draw Ratio (LDR). The formula is: LDR = D / d D = blank diameter d = cup ID or punch diameter This ratio shows […]
Commonly Asked Questions about Cylindrical Applications What are stainless steel spools? A spool is a fabricated length of tubing with clamp fittings, or flanges at both ends. A couple popular names are cylinders, extensions, tubes, spools, rings, or cylinders. These pieces are classified as spools when the flanges are on both ends. What is a

What is Seam Welding? Seam welding is the process of joining two similar or different materials together, at the seam, by electronic current and pressure. The gap creates an electrical resistance between the materials, which causes them to heat up at the seam. This process is most common with metals, because they conduct electricity easily,

The Process of Forming Deep-Drawn Metal Stamped Aluminum Parts Aluminum is a very formable material, making it the perfect candidate to be deep drawn, stamped, or hydroformed. The deep draw metal stamping processes is a cold-forming process, meaning the material’s grain structure undergoes changes at room temperature, as the blank forms and stretches into its
