Deep Draw Stamping: The Ultimate FAQ Guide
What is Deep Draw Stamping?
Deep draw stamping is a metal processing method used to create open hollow parts from flat or hollow material by using a deep drawing die under the pressure of a press. Cylindrical deep-drawn aluminum cans are a common application of this technique.
What are the Types of Deep Drawing Processing?
Deep draw metal stamping manufacturers generally divide the process into four parts: Drawing Processing, Redrawing Processing, Reverse Drawing Processing, and Thinning & Drawing processing.
??The drawing process involves using a plate device and the stamping force of a punch to pull part or all of the flat plate into the cavity of the concave mold to form a container with a bottom.
??Redrawing processing is necessary to increase the depth of the forming container.
??Reverse drawing processing involves turning the drawn workpiece from the previous process inside out, with the inner part becoming the outer part, and the outer diameter becoming smaller.
??Thinning and drawing processing is where a punch squeezes the formed container into a concave model cavity slightly smaller than the outer diameter of the container, so that the outer diameter of the container with the bottom becomes smaller.
What is the Deep Drawing Process?
The deep draw stamping process can be divided into three stages:
1??local deformation?stage,
2??main deformation?stage,
3??pushing?stage.
What are the Main Factors that Affect the Deep Drawing Coefficient?
The main factors that affect the deep drawing coefficient include:
1)?mechanical properties of materials,
2)?relative thickness of the material,
3)?number of times of deep drawing,
4)?deep drawing method,
5)?radius of convex and concave die fillet,
6)?smoothness of the drawing surface, the lubrication condition, and the drawing speed such as clearance.

What Materials Are Used?in Deep Drawing?Parts?
Deep drawing parts are made from a variety of materials, including:
??low carbon steel,
??stainless steel,
??aluminum alloy,
??copper alloy,
??titanium.
The raw materials used have different drawing characteristics that affect the elongation rate of the product, as well as the ratio of the diameter of the blank to the diameter of the stamping die.
What Factors Affecting the Quality of Deep Draw Sheet Metal Parts?
There are many factors affecting the quality of deep-drawn sheet metal components, including the shape and size of the part not meeting requirements, parts having cracks and wrinkles, and obvious contour changes. Wrinkling and cracking are the main obstacles to the smooth process of deep drawing.
Commonly Used Drawn Metal Parts
Deep drawing manufacturers commonly produce deep-drawn boxes, deep-drawn enclosures, and other parts using deep-drawn stampings. These parts are used in various industries, including
1)?Battery cases,
2)?Button batteries,
3)?Pacemaker shells,
4)?Connector shields,
5)?Sensor housings,
6)?Power battery explosion-proof valves,
7)?TWS earphone cases,
8)?Hearing aids.
