4-Stage Deep Drawing Process

At Kailai, we utilize an advanced four-stage deep drawing process to manufacture complex metal components. By gradually shifting material stress across multiple operations, we eliminate the risk of structural failure or tearing caused by excessive single-stage deformation.

Stage 1: Initial Forming & Surface Matching

The process begins by forming the metal blank into an initial shallow shape. The critical requirement here is that the surface area of this preliminary piece precisely matches that of the final component. This strategic design ensures uniform material distribution across subsequent stages and prevents localized thinning.

Stage 2: Incremental Deep Drawing

Next, the component is drawn deeper in a controlled, progressive sequence. Building the depth step-by-step from the bottom up drastically reduces instantaneous material stress, effectively mitigating the risk of fracturing or cracking.

Stages 3 & 4: Precision Calibration & Finishing

The final two stages focus on structural refinement and detail finishing. These operations calibrate sidewall perpendicularity, optimize flange flatness, and correct micro-dimensional deviations.

Through this meticulous multi-stage approach, Kailai consistently delivers highly complex deep-drawn parts that meet rigorous precision and quality standards.
