What Is A Stamping Mold?

Stamping Mold can be defined as the process equipment used to exert pressure on a blank for it to go through steel transformation.

The blank can also undergo transformations that produces workpieces having definite properties, shapes and with fixed sizes.

Stamping is a method of pressure processing that utilizes a mold placed on a press to insert pressure on a metal surface causing deformation.

The result is the formation of the required design part.

What Are The Limitations Of Stamping Mold For Metals?

The major demerit of Stamping Mold is that tooling expenses are high hence not feasible for short-term and low-scale production.

Manufacturing and developing such equipment usually takes a long time to complete.

This means that any changes in the mold design will necessitate additional costs and modification challenges may arise.

How Does Progressive Stamping Mold Process Work?

Progressive Mold Stamping involves a variety of stamping stations each with its own unique function. The sheet metal or strip of metal steadily unrolls from the coil into the die press where each station performs its operation.

The operations include bending, punching, cutting (collectively stamping) with each station adding work from the previous station.

The end result is the complete required design part.

This type of process is recommended for parts that have a complex geometry hence the use of multiple stamping molds.

Secondary machining procedures are however required after processing to have the part entirely complete.

What Are The Different Classifications Of Stamping Molds According To Degree Of Process Combination?

The classifications are as follows:

a. Riveting Mold – this is a mold that makes use of an external force to have the parts involved overlap or join.

This is done in a specific designed manner so as to form a whole unit part.

Rivet molds

b. Punching Mold – this type of mold ensures separation of materials along an outline that is either open or closed.

punching mold

They perform processes like slitting, punching and cutting.

c. Forming Mold – this mold replicates the blank directly or the semi-finished workpiece based on the concave or convex mold shapes.

forming mold

Such molds include shaping molds, bulging molds, flanging molds and undulating molds.

d. Bending Mold – this mold is used for the deformation or bending a blank sheet metal or any other blanks.

Bending mold

 The bending or deformation occurs along a straight line creating a definite shape and angle.

e. Drawing Mold – this mold normally transforms the sheet blank into a hollow part that is open.

It can also alter the size and shape of the hollow part further.

What Are The Stamping Mold Maintenance Procedures?

Stamping Mold should undergo regular checks by the operator during and after production. Some of the maintenance procedures include:

i. All the sliding parts of the mold and its general assembly should well lubricated and grease applied regularly.

ii. The safety parts and all other mold parts should be subjected to regular inspection. The safety side pins, punching waste channels side guards and safety screws should all be inspected.

iii. After completion of each production cycle, the mold should be subjected to a comprehensive inspection.

iv. The mold should be thoroughly cleaned after every production.

v. All the waste gathered after production inside the mold should be removed and waste box emptied.

What Is The Basic Stamping Mold Process?

Stamping (also called pressing) using a mold includes placing a blank metal form or a flat sheet metal in a stamping press.

The mold, under pressure, then presses into the blank form or the metal sheet to produce a definite design shape.

The stamping mold process involves operations like embossing, flanging, punching, bending and blanking.

Before the part can be produced, it is first designed using the CAD/CAM software technology.

The designs are accurate and very precise to ensure adequate clearance and to achieve optimal part quality.

After establishing the part design and producing, operations such as grinding, machining and surface finishing can be used to complete the part.

What Are The Advantages of Stamping Molds?

The advantages of Stamping Molds are as follows:

Cost Efficient

Stamping molds work faster with very minimal labor and machine operation procedures.

It is considered one of the most cost-efficient processes used in metal forming with provision to produce large quantities of parts.

Simple Operation

Operating a stamping Mold requires very little effort and the skill range of the operator is not as high as other operations require.

Automation

Stamping molds can easily be integrated in automated subordinate procedures such as stamping and welding in stamp.

This improves efficiency and an increase in total parts produced.

Reduced wastage

Due to its consistency and accuracy, there is a significant reduction in the amount of sheet metal going to waste.

Automation also ensures that parts are stamped as close together as possible

Enhanced Accuracy

Using a stamping mold produces very detailed and composite parts with extreme accuracy.  Intricate shapes mostly do not need further machining after production.

What Are The Separate Parts Of Stamps Used In Stamping Mold?

Stamps contain a variety of separate parts that can be classified into several groups namely:

• Body Parts: they are the connection between the mold, the working parts and the machine tool. They include lower shank plates, columns and guide bushings.
• Structural Details: their serve as the connection between various parts connected to the body structures of the Stamping Mold.
• They include punch holders, matrix holders and all other available fasteners.
• Working Parts: these include parts involved in the creation of the final workpiece shape (molds with separate sections and punches). Loading chambers are also included in working parts.
• Removable Parts: they are made up of designs of ejectors and pullers which allow the manufactured part to be detached.

What Are The Various Stamping Mold Materials?

Stamping Mold is mostly made of various types of steel. They include:

Carbon Steel Tool

T8A and T10A are the most regularly used carbon steels in making Stamping Molds.

Their main advantage is that they cost very little and possess good processing performance.

Nevertheless, they have a large heat treatment deformation with very poor red hardness and hardenability.

carbon steel tool

They also have the disadvantage of a low bearing capacity.

High-speed Steel

This type of steel contains the highest hardness with a good compressive strength and wear resistance compared to other steels.

W18Cr4V and W6Mo5 Cr5MoV with little tungsten content are the commonly used high -speed steels in Stamping Molds.

high speed steel

To improve its distribution of carbide, high-speed steel has to be forged.

i. High-Carbon High-Chromium Tool Steel

The most regularly used steel of this caliber Cr12, Cr12Mo1V1 and Cr12MoV.

Some of their properties include a high resistance to wear, good hardenability and with very minimal heat treatment deformation.

However, the have a very serious carbide segregation with forging and upsetting done repeatedly.

high carbon high chromium tool steel

This is to improve its performance and lower the carbides unevenness.

High-Carbon Medium-Chromium Tool Steel

The Tools steels used for this type in Stamping Mold include Cr4W2MoV, Cr5MoV and Cr6WV. With little eutectic carbides and lower chromium content, their carbide distribution is uniform.

Their heat treatment deformation is small with good dimensional stability and exceptional hardenability.

high carbon medium chromium tool steel

 In comparison to high-chromium high-carbon steel, it has improved performance.

 Base Steel

Base steel is formed by addition of small quantities of new elements to high-speed steel’s basic composition.

The carbon content is then appropriately decreased or increased to increase the steel performance.

base steel

Besides having the high-speed steel characteristics, their fatigue strength is better and their toughness is improved.

They have a lower material cost compared to other steel.

Why Is The Mold In Precision Stamping Mold Without Cavities?

The cavities are not present in a Precision Stamping Mold because they might restrict the process of removing the piece.

Undercuts in precision stamping, undercuts (90° angles or more) are usually avoided because from the mold, they create the indivisible printed element.

Is There Any Assistive Technology Used With Stamping Mold?

Recent developments in technology has given rise to new mechanical design technology in the manufacturing industry.

Computer-aided Design (CAD) and Computer-Aided Manufacturing (CAM) are the major technologies that are used with Stamping Mold.

The CAD/CAM technology is a high-efficiency high-tech system that provides an operational supplementary tool in the form of a software.

This enables technicians and machine operators to control production of parts using computers.

Mold CAD/CAM shortens the mold design significantly and reduces the manufacturing cycle and product cost.

Its precision and accuracy ensures the quality of parts produced is very high and greatly improved.

What Are The Precautions When Using A Stamping Mold?

It is very crucial that a gap be established between the die and the puncture.

The gap relies on the type of material used (soft or hard) and the thickness of the metal sheets or plates.

Large gaps tend to cause burrs which normally damage the operators while small gaps bring about cracks that affect subsequent operations.

The smaller the sheet metal or plate thickness, the smaller the gap should be and vice versa.

What Is The Process of Single-Action Stamping Mold Installation?

• The worktable guide rails are first cleaned off debris before being opened to prevent interference with the main column during operation.
• The ejector rod is then installed ensuring that its length is consistent.
• The stamping Mold is then lifted on the work table and aligned to the center of the press.
• The upper and bottom surfaces of the Mold are then cleaned before placing it.

After placement, the alignment of the Mold should match with the presses T-Groove for effective installation.

• The mold installation height is then adjusted to the Mold storage height +10cm.
• The Mold is then cleaned and well lubricated with the moving parts thoroughly greased.
• The Mold Assembly height is then finely adjusted.
• Testing can then be done on a single sheet metal to ascertain operation ability.

What Are The Common Separating Processes Used In Stamping Mold?

The Stamping Mold most common separation processes include:

• Trimming
• Blanking
• Parting
• Cutting
• Piercing
• Shaving
• Lancing

What Are The Demerits Of Stamping Molds?

Stamping Molds have the following disadvantages:

High Tooling Costs

The stamping mold requires constant tooling maintenance and is costly when mold changes are required.

Creating different custom molds and changing also increase the tooling and maintenance cost.

Unsuitable for Small-Scale Production

Rapid prototyping and small scale production are not feasible using stamping Molds due to high operational costs.

The designing, tooling and the eventual set-up consume a lot of time for small scale production.

What Is The Importance Of Stamping Molds In Metal Stamping?

The metal Stamping Mold has turned out to be an essential add-on that plays a very crucial role in the metal forming processes.

For the mold to serve its purpose of exerting pressure, it has to be together with the stamping metal plates.

The molding of the metal is generated based on each individual design requirement presented.

The metal stamping mold has become very common in modern everyday applications and it requires very minimal maintenance.

metal stamping

Its lifespan is very long hence eliminating the need if regular replacement over short periods of time. It also decreases the cost of production based on that.

What Are The Factors To Consider When Choosing A Stamping Mold?

There are some essential considerations needed while choosing a stamping mold for a project. They include:

• Design – if an existing part of the project is available, it is better to share it with the stamping mold designer.

However, specifications and sketches for complex designs should be given to the designer to come up with an appropriate stamping mold.

• Material – the metal material to be stamped defines the type of material that will be used to make the stamping mold.

Factors like thickness, size and material characteristics are some of the factors that will determine the material.

• Cost – stamping mold is normally made of various types of steel each with its unique characteristics and material traits.

Their process vary hence the price will depend on the project budget or quality of parts required.
