Custom Progressive Die Development & Production, Optimizing Material Yield & Reducing Piece Cost
1．Progressive Die Stamping Quick Detail
We specialize in processing progressive die stamping parts with forming characteristics such as stretching and flanging. Through reasonable station arrangement and die structure design, we can reliably manufacture stretched cups with uniform depth, clearly defined flanged edges, and high-precision hole groups on a continuous production line. This process is particularly suitable for housing and cover parts that require good appearance and certain structural strength, and has wide applications in fields such as new energy batteries and communication chassis.
2. Progressive Die Stamping Product Description
For parts that require both functionality and aesthetics, progressive die stamping offers a highly efficient solution. We focus not only on the final dimensions of the parts but also on material flow control during the forming process to avoid defects such as cracking and wrinkling. For products such as electrode connectors for new energy batteries, shielding covers or heat sinks for communication equipment, we optimize the design of the drawstring ribs, control the blank holder force, and arrange the annealing between processes to ensure perfect part shape and surface quality while maintaining high production efficiency.
3． Progressive Die Stamping Product Features & Advantage
|
Feature |
Advantage to You |
|
Stable Drawing within Progressive Dies |
By setting up multi-station progressive drawing in the progressive die, the material thinning rate can be effectively controlled, and drawn parts with uniform depth can be produced stably, avoiding the risk of breakage caused by a single deep drawing. |
|
High-Precision Flanging & Hole Position Assurance |
After forming, precision punching and flanging are performed at the post-forming station to ensure the positional accuracy of the holes relative to the formed contour, thus meeting the assembly and sealing requirements of shell-type parts. |
|
Surface Quality Control for Appearance Parts |
From material selection to mold cavity polishing and cleaning control during the production process, multiple dimensions ensure that the surface of the parts is free of scratches and indentations, providing a perfect substrate for subsequent anodizing and other treatments. |
|
Integrated Realization of Heat Dissipation & Shielding Functions |
Dense arrays of heat dissipation fins or electromagnetic shielding finger springs can be molded onto parts in one step, improving product functionality and reducing subsequent assembly. |
|
Lightweight-Oriented Material Solutions |
Proficient in using lightweight materials like aluminum alloy for progressive stamping and forming, helping your products achieve weight reduction goals while ensuring strength. |
