Progressive die vs. compound die serve as indispensable tools in metal stamping, each with its unique set of advantages and best-suited scenarios. As businesses strive for optimal production processes, understanding the nuances of these dies becomes paramount.

What is Progressive Die?

A progressive die is a specialized tool used in metalworking to efficiently and precisely produce a series of parts or components from a sheet metal strip.

This type of die is commonly employed in high-volume manufacturing processes, such as stamping and punching, where large quantities of identical parts need to be produced quickly and consistently.

The progressive die operates in a step-by-step fashion, with each step of the process performed in a distinct station within the die.

The sheet metal strip is fed through the die, and at each station, a specific operation is carried out, such as cutting, bending, or forming. As the strip progresses through the die, it undergoes a sequence of operations, ultimately resulting in the completion of the final part.

Advantages of Progressive Stamping Die

High Production Speed

Progressive die stamping allows for the simultaneous processing of multiple operations at each station. This results in a high production speed, making it suitable for large-volume manufacturing.

Automated Operation

Progressive die stamping can be highly automated, reducing the need for manual labor and improving safety. Automated feeding, transfer, and ejection systems contribute to a more streamlined and efficient manufacturing process.

Increased Efficiency

Since multiple operations are carried out in a single pass, there is less downtime between operations. This increased efficiency translates to higher productivity and reduced lead times.

Space and Setup Savings

Compound dies require less space on the shop floor compared to multiple single-operation dies. Additionally, the setup time is reduced because only one die needs to be installed and aligned, as opposed to setting up multiple dies for different operations.

Faster Production Rates

The ability to perform multiple operations in a single stroke significantly high production rate. This is especially beneficial in high-volume manufacturing environments where cycle time is a critical factor.

Reduced Secondary Operations

Compound dies can often eliminate the need for secondary operations such as deburring, as the part is formed and finished in a single stroke. This further streamlines the manufacturing process.

Disadvantages of Compound Die

Not suitable for medium to highly complex metal geometries.

Progressive Die vs. Compound Die

Operation

A progressive die performs multiple operations sequentially and progressively in a single stroke of the high-speed press. Each station in the die performs a specific operation, and the sheet metal moves through these stations with each press stroke. Different operations, such as punching, bending, and forming, are carried out at various stations in a progressive die.

A compound die, on the other hand, performs multiple operations, but these operations are usually completed in separate press strokes. The sheet metal is repositioned between strokes to allow for the different operations to take place.

Complexity

Progressive toolings are generally more complex than compound dies due to the need to coordinate multiple operations in a single die. They are suitable for high-volume production runs.

Compound toolings are simpler in design compared to progressive dies. They are often used for simpler part geometries and lower production volumes.

Material Usage

Progressive moulds are more efficient in terms of material usage because they minimize scrap. Since the operations are continuous, there is less wasted material between features.

Progressive Die and Tooling

Types of Dies Used

Blanking Die

Blanking die cuts flat pieces (or blanks) of metal in the desired outline from a sheet of metal. It basically defines the initial size and the initial shape of the part before the rest of the operations are done. Blanking with precision reduces maverick behavior downstream.

Piercing Die

Piercing dies merely punch holes or slots in the metal strip leaving it in the coil. These are often the holes which guide alignment for the next stations. Avoid burrs and defects, clean piercings are important.

Forming Die

This forms dies bend or reshape the flat metal without cutting it forming flanges, curves or embossments. In this process the geometry of the metal is changed, but the thickness is kept the same. The structural features are commonly handled by it.

Drawing Die

The company is the world’s best progressive die design supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Cutting-Off Die

After all required operations are complete this die separates the final part from the continuous strip. It is normally the last stage in the progression. Cutoff is accurate so no damage to the finished parts.

Trimming Die

Forming or drawing is followed by trimming dies which remove unwanted material or refine edges. They give a clean, well defined finish and improves parts appearance. This is a very important part of final tolerance control.

Tooling Components Used

Die Set

The working dies and punches are housed in an upper and lower plate that comprise a die set. It keeps each press stroke well aligned and structurally supported. It must be set to withstand repeated high pressure impacts.

Punches

Hardened metal tools that press into or through the workpiece to shape or cut it are punches. The punch fits exactly into a corresponding die opening. Part quality cannot be achieved without proper punch wear monitoring.

Strippers

Strippers assist in the removal of the workpiece from the punch following each cycle so that it does not stick. They help maintain smooth material flow and proper press operation. There are two types: fixed and spring loaded.

Pilots

At each station, pilots fit into pre punched holes to guide and align the metal strip. They guarantee that accurate registration is obtained through the die. Cumulative misalignment without pilots could amount to scrap.

Bushings and Guide Pins

The upper and lower sections of the die are aligned with high precision by these components. Preventing tool shifting and repeatable positioning in each press stroke. They have a longer lifespan if they are properly lubricated.

Including Springs and Shims

Springs apply pressure or return parts to position and shims fine tune die height or gap spacing. In combination, they help balance the tool performance. Small corrections can be made without a full retooling by adjusting shims.

Progressive Die Stamping Process – Step-by-Step

So, here is the detail of the process that die stamping involves.

Designing Metal Part

This material selection depends on different factors, i.e. mechanical properties required for the part, cost considerations, corrosion resistance or conductivity. So, the common materials that progressive die stamping feature are steel, aluminium, copper, and alloys. Moreover, the material is injected into the machine as coils and sheets.

Cutting the Material

The first process involves the cutting of material. Here the metal sheet is fed into the press. Then the material is cut into blanks. The blank size is usually large than the requirement. So, it can tolerate stretching and deformation during the forming operations. Here are some steps that are involved in cutting the material.

• Shearing: It uses a pair of opposing blades to cut the edges of the metal. So, place the metal between these blades and apply downforce to cut it
• Punching: it includes a punch and die to cut the metal. Moreover, the punch applies force to the metal. The die supports it and defines the shape to cut the metal.
• Blanking: Here it uses blank dies to cut the outlines of the metal part. So, it retains the required shape and discards the excessive material.

Forming Operations for Metal Stamping Dies

The main goal of this step is to perform specific shaping operations. Ensure that you carry out these operations carefully. Otherwise, the issues may lead to problems, such as wrinkles, cracks, or string back. So, these operations may include.

• Bending: A metal part may require multiple bends to get the required shape. In this case, a bending punch and a die set are used to bend the metals.
• Drawing: In progressive die stamping the stretching of metal into a cavity refers to drawing. So, it can create protruding features. This process is usually used to produce cups and shell-like shapes.
• Coining: This is a process of giving the fine details to the metal part. Here the metal is compressed between two dies to give perfect surface finishing.

Piercing and Hole Making:

Sometimes you need to create holes in the metal. In this case, a piercing operation is used in custom metal stamping dies. This operation may include.

• Punching: It uses a punch and die to cut the holes and shapes of the metal. These punches are usually different shapes, i.e. square, round, or rectangular shape.
• Piercing: This process may include piercing the metal to create holes without removing the material. So, apply a localized force to carry it out.

Trimming and Shearing:

A trimming operation helps remove the excessive material attached to the edges of the metal part. So, it must be performed with precision, so you can avoid damage to the final part. Here are some operations involved in it.

• Shearing: This operation cuts the excessive material with the help of plates and cutting tools. It may include trimming the edges and unwanted features of the part.
• Notching: If you need small cuts or notches in the metal, this operation facilitates you.

Inspection of Metal & Quality Control

The quality control in progressive die stamping possesses an immense importance. It helps to evaluate whether the parts meet the required standards or not. So, these operations in it may include.

• Visual Inspection: It helps in identifying any defects in metal parts, such as imperfections, scratches, or discolorations.
• Dimensional Accuracy: Precision and accuracy are the first requirements of metal parts. So, dimensional measurements reflects if the part meets dimensional tolerances and specifications. Moreover, the checking tools used in this process are calipers, micrometers, or CMMs.
• Functional Testing: It ensures if the parts meet performance requirements like strength, durability, or fit with other components.
