What is stamping used for?

Metal stamping is a manufacturing process used to transform flat metal plates into specific shapes. This is a complex process that can involve a variety of metal forming techniques - blanking, stamping, bending and punching, etc.

 

We will learn stamping from the following points:

 

What is a good stamping

Basic stamping knowledge

Types of metal stamping and what they used for

 

1. What is a good stamping

 

Thousands of companies in the United States offer metal stamping services, providing components for industries in the automotive, aerospace, medical and other markets such as the latch. As the global market develops, the need to produce large numbers of complex parts quickly is increasing.

 

Metal stamping is a fast and cost-effective solution to meet this mass manufacturing requirement. Manufacturers of metal parts that need to be stamped for a project usually look for three important qualities:

 

Durable

Low Price

Fast Turnaround Time

 

The following guide describes best practices and formulas commonly used in metal stamping design processes and includes tips for incorporating cost-cutting factors into parts.

 

2. Basic stamping knowledge

 

Stamping (also known as pressing) involves placing a sheet metal in roll or blank form into a punch machine. In a press, the surface of the tool and die forms the metal into the desired shape. Stamping include punching, blanking, bending, stamping, embossing, and flagging, that used to shape metals.

 

Before forming the material, the stamping professional must design the die through CAD/CAM engineering techniques. These designs must be as accurate as possible to ensure that appropriate clearances are maintained for each punch and elbow, thus ensuring optimal part quality. A single tool 3D model can contain hundreds of parts, so the design process is often complex and time consuming.

 

Once the tool design is determined, the manufacturer can complete its production using a variety of machining, grinding, wire cutting, and discharge machining (EDM) and other manufacturing services.

 

3. Types of metal stamping and what they used for

 

There are three main types of metal stamping techniques: progressive, four-slip, and deep stamping.

 

Progressive stamping

 

Progressive stamping has multiple stations, each station has a unique function.

 

First, strip metal is fed into a progressive stamping. The strip is steadily unrolled from the coil into the die press, where a different cut, punch, or bend is performed at each station in the die. The actions of each subsequent site add to the work of the previous site, thus completing part of the work.

 

The manufacturer may have to change tools repeatedly on a single press or occupy multiple presses, each of which performs the action required for a complete part. Even when multiple presses are used, secondary machining services are often required to actually complete the part. Therefore, progressive die stamping is an ideal solution for metal parts with complex geometry, which can meet:

 

Faster Turnaround

Lower Cost

Shorter Run

Higher Repeatability

 

Fourslide stamping

 

Fourslide (or multiple slides) stamping involves horizontal alignment and four different slides. This process allows complex cutting and bending to be performed to develop the most complex parts.

 

Compare the fourslide stamping and traditional stamping, there are some advantages for fourslide stamping which include:

 

Suitable for more complex parts

Design changes are more flexible

 

As the name fourslide stamping has four slides, that means you can use up to four different tools to achieve multiple bends simultaneously. As the material enters the four chutes, each shaft equipped with the tool bends it in rapid succession.

 

Deep stamping

 

Deep stamping involves pulling a sheet metal blank into a die through a punch to give it shape. When the depth of the drawing part exceeds its diameter, the method is called "deep drawing". This type of molding is ideal for creating parts that require a series of multiple diameters and is a cost-effective alternative to the turning process, which typically requires more raw materials. Common applications and products made by deep drawing include:

 

Auto parts

Aircraft parts

Electronic relay

Cutlery and cooking utensils
