The deep drawing of thermoplastics
Polymer Engineering & Science, 1977AbstractThe theory of deep drawing, which has been developed for metals, is examined critically for thermoplastics. Two special characteristics of thermoplastics, the strong orientation hardening after initial yielding and the ease of crack formation and growth, are shown to vitiate the usual correlation between the drawability of the sheet and the low

On the acting pressure in laser deep drawing
Production Engineering, 2008Through the continuing trend of miniaturization new cost efficient and fast methods for processing of small parts are required. In this paper a non-mechanical process for the forming process of micro deep drawing is presented. This new pulsed laser based deep drawing process utilizes an initiated plasma shock wave at the target, which forms the sheet ...

Deep Drawing Height Analysis of Rectangular Cup Drawing
Volume 3: Design and Manufacturing, Parts A and B, 2010The deep drawing process is widely used in industry because it allows the production of parts with reduced weight and good mechanical properties. However, the deep drawing process of non-cylindrical shapes still relies on experimental and trial and error methods, leading to high costs and long development times.

The term metal forming refers to a group of manufacturing methods by which the given shape of a workpiece (a solid body) is converted to another shape without change in the mass or composition of the material of the workpiece. In this paper, the basics of a deep drawing process for the production of a thick plate steam boiler end caps are shown.

A Review on Deep Drawing Process
International Journal of Emerging Research in Management and Technology, 2018Deep Drawing (DD) process is the one in which a punch forces a flat sheet metal blank into a die cavity. DD can also be described as the process which involves conversion of flat thin sheet metal blanks into parts of desired shape. Little work is available in the applications of DD processes at elevated temperatures which is going to be a very ...

A method for estimating the limiting drawing ratio in deep-drawing
International Journal of Production Research, 1974The new method of estimating the Limiting Drawing Ratio (L.D.R.) in deep-drawing makes use of oversize blanks with standard diameters. Experimental results indicate that the bulge depth at fracture, to blank diameter curves for oversize blanks can be expressed by a particular type of an exponential expression. To evaluate the parameters in the equation,

Hydrodynamic lubrication of deep drawing
2020An isoviscous steady hydrodynamic lubrication model for a deep drawing process is developed. Equations to calculate lubricant film thickness, radial, and drawing stresses are presented. The die inlet film thickness is related to the properties of the lubricant and the sheet metal, the tooling geometry and the operating conditions.

This research work presents recent results on the formability of paper-based materials. Different kinds of commercial paperboard samples were evaluated using a laboratory 2D - formability tester, and a 3D deep-drawing equipment. It was found that the appearance of the formed shapes and the performance of paperboard in the forming process have a ...
