Progressive die stamping is widely used in electronic components and automobile manufacturing industries, which can realize multi-functional stamping operations in the same set of progressive die molds, such as cutting, stamping, punching, stretching and automatic feeding functions.
Progressive Die Stamping: Best for maintaining high-speed consistency. Achievable tolerances typically hover around ± 0.05 mm for critical features.
Deep drawing stamping services
relying on custom deep drawing services, metal sheets can be manufactured into thin-walled parts with cavity structures such as trapezoids, cones, spheres, rectangles, etc., keeping the wall thickness uniform, which is one of the very important sheet metal fabrication processes .
Deep Drawing: Focuses on wall thickness uniformity. We manage thinning ratios to ensure structural integrity, typically maintaining ± 0.12 mm on cup diameters.

An Overview for :
What is sheet metal stamping processing ？
Metal stamping is a cold forming manufacturing process. The metal plate is deformed or cut instantaneously by pressing the stamping die by the stamping equipment to produce custom metal stamping parts with different shapes.
Metal stamping technology has been widely used. A variety of stamping technologies can be used according to different parts design, but they all require the cooperation of rigid stamping dies and pressure to complete blanking, bending, stamping, Coining, embossing, deep drawing or Manufacturing processes such as scraping metal.
Custom metal stamping services are very suitable for low-cost high-volume manufacturing, high-efficiency manufacturing of tight tolerance parts with complex geometries, complex details, and key shape and surface features.
It is generally used in the initial stage of custom metal stamping projects. The metal sheet is cut into the part designed 2D shape using a mold to prevent excess materials from affecting the product shape in the subsequent process, and the blanking step can reduce burrs on the part. Risks brought by the stamping process.
It can also be used in the later stage of deep drawing to efficiently cut off excess material.
Bending using custom metal stamping dies is an important step for turning flat (blank) plates into three-dimensional parts, which can be bent and folded quickly and accurately. In the bending process, cracks are very easy to appear. It is necessary to pay great attention to the yield strength of the material and the direction of the internal structure of the material, and perform stamping and bending reasonably.
Use molds to create high-precision hole designs on metal plates in batches, with a minimum error of ±0.02mm and keep the material cut smooth.
In order to form the multi-curved surface of the material, we need to use deep drawing stamping to press the metal plate into the mold under pressure to quickly form irregular shapes such as multi-curved surfaces. In this process, the excess material will be used by the mold. Fix it first, and cooperate with lubricating oil to quickly deform the metal sheet.
Relying on strong pressure to press the mold on the material, the surface of the product is printed with complex patterns or text, usually the impression created by embossing to make the concave shape, which requires high hardness produced by the mold after heat treatment. Similar to the pattern on a coin.
Usually, the material is folded by 90° to become the flanging, which requires the material to have excellent yield strength, and the gap size after the folding should be set reasonably to prevent the material from cracking after the extreme stamping and flanging. It is generally used for metal such as tableware. The edges of the container prevent sharp materials from cutting the skin and causing injury.
Flanging is usually divided into several steps, firstly bending over 45°, and then flanging according to product design.
