Progressing metal stamping is the process that is used to form metal and create customized parts of a wide range of shapes and sizes for almost every industry in the world. Progressive dies are generally used in projects where parts are required in high volumes and require an intricate level of customization. 

Progressive press tools are generally made of tool steel. This alloy can withstand high shock loading, maintain the required cutting-edge precision and endure high pressure that is applied through the process. 

Some of the most common metals that are fed into a progressive stamping press are:

1. Copper

2. Aluminium

3. Stainless steel

4. Brass 

5. Steel

Progressive Metal Stamping Process:

Progressive metal stamping requires several workstations, where each one facilitates one part of the production process. The metal sheet that is fed into the stamping press moves from one station to the next via a stock strip. The final product is then removed from the final station once the process is complete. 

There are several processes incorporated into the progressive metal stamping method, some of which are bending, coining, punching and embossing. Each of these techniques is aligned with the automatic metal feeding system of the press. 

A strip of metal is unrolled from the coil when it is drawn from the feeding system. This allows every station to complete its task in the process, resulting in a finished component. The material from which the part is separated at the end is known as the carrying web, which is moved to a scrap bin. Once the cutting process is complete, the carrying web is recycled and reused.

There is a unique task performed at every station through the progressive stamping process. Therefore, the progression of the metal strip must be extremely precise. The level of precision needs to be as much as a thousandth of an inch or smaller, which is often the requirement for intricate components and parts. 

Types of Precision Stamping:

There are two main stamping die types - a transfer die and a progressive die. Business enterprises account for several factors while choosing which of these dies they should use for their manufacturing process, which includes

- Nature and complexity of the components required

- Size of the component

- The part volume that is ultimately required

As mentioned before, progressive stamping is the right option for business projects that require large volumes of components, lower cost of production and a high level of efficiency. 

Factors to Ensure Quality Standards in Progressive Stamping:

Progressive dies are ideal for creating complex components. However, there are several factors to consider to ensure each component has the same specifications and turns out identical. Some of the key factors are:

- Blank boundary

- Blank position

- Stretch-web deformation

- Pilots

Additionally, also need to consider the interaction and timing of 

- Pads

- Upper and lower tools

- Carriers

Applications of Progressive Die Stamping:

Progressive stamping is a versatile process that has applications across almost every industry. Some of the industries where progressive stamping is most widely used are:

- Aerospace

- Appliances

- Automobiles

- Electronic devices and components

- Retail and office equipment

- Healthcare

Some of the most popular products that are made using progressive stamping are the lids with pull tabs on soda cans, brake callipers in cars, hooks, hinges and shelf angles that you see at home, and several intricate parts of electronic devices.

Benefits of Progressive Stamping:

Your business will see many tangible benefits of using progressive stamping. This includes:

1. Higher production speed: Progressive stamping uses a continuous feed system for the material. This saves time that would have been wasted on transferring parts from one station to another and reduces the per-component cycle time.

2. Faster setup: Compared to other modes of production, progressive die stamping has a lower setup time since it is a single piece of equipment.

3. Reduced scrap: The combination of multiple methods like punching, coining and bending brings down the amount of metal that is thrown away as scrap.

4. Higher repeatability: Hard tooling makes high-volume runs possible without degrading the dies. This ensures high-quality output.

5. Lower cost: Business owners who use a progressive stamping press save money on setup, production, material and turn-around-time. This becomes a significant amount of savings in the long run.

There are many benefits of opting for a progressive stamping press or tool. The incorporation of this method of production into your manufacturing infrastructure can optimize and maximize your output and profits.
