Difference Between Multi-Slide & Progressive Die Stamping

Difference Between Multi-Slide & Progressive Die Stamping

In everyday life, machining and manufacturing processes in different industries often require the use of precision metal stampings made from slit coil steel, copper, brass, and other materials. Metal stamping presses can be used to manufacture these metal stampings. Depending on the need for metal stamping parts, you can choose the right metal stamping machine accordingly.We have provided the Difference Between Multi-Slide & Progressive Die Stamping below!

There are several different types of metal stamping presses. The first is the progressive die stamping press, which can process metal parts until they are made into finished components. This type of machine has an automatic filling system that performs operations such as punching, embossing, and bending to change the raw metal material and make the finished product.

A four-slide or multi-slide press is another type of metal stamping machine. It can make shapes and bends of varying difficulty. A large number of machined parts can be made from cut coils or wires using this machine.

Progressive Die Stamping Machine

In processing metal materials, a progressive die stamping tool moves in a vertical direction. In a progressive die stamping press, the slit coil metal passes through multiple stamping stations. Each station accomplishes a different process.

At the first station, the die cuts, bends, or opens the metal strip on a schedule. The workpiece is then transferred to the next station where the next stamping task is completed. This process continues until the final product is completed. Depending on the complexity of the final metalworking part, there may be only one step or there may be more.

Progressive Die Stamping

Advantages of Progressive Die Stamping

Progressive die stamping is superior to other stamping methods, such as four-slide or multi-slide tools, in many ways.

Short Setup Time

Setting up a progressive die stamping takes 38% less time than a multi-slide stamping. Because of this, manufacturers can produce smaller batches and have better control over production schedules to produce the products their customers want, when they want them. This also reduces the amount of work involved in part manufacturing.

Reliability

Progressive die stamping presses have very good reliability and very tight tolerances. They are able to manufacture large quantities of parts without compromising on standards.

High Precision

Since each station does a different job, progressive die stamping presses are very efficient and can manufacture large quantities of parts with high precision.

Universal Mold

Since the molding process is very simple, only vertical pressure is used. Therefore it is possible to change the METAL STAMPING FACTORY without having to make extensive modifications to the mold.

In most cases, if there is another press with the same bed size and tonnage, the tooling used on that bed size and tonnage can also be used on the other press.

Disadvantages of Progressive Die Stamping Presses

There are many benefits to using a progressive die stamping press to fabricate sheet metal, but there can be some disadvantages as well.

Cost

One of the biggest problems with this type of metal stamping machine is the high investment cost. Graduated die stamping dies can be very expensive, so metal stamping factories need to make sure that they can make enough money to cover the cost.

Time-consuming Project Switching

Graduated die-stamping presses can take a lot of time when you are switching between projects. This is because the settings need to be set up or changed for each job. As a result, it can be difficult to switch between jobs quickly.

More Waste

Progressive die stampers create waste. Throughout the process, the workpiece must move along the strip, thus wasting the material needed to keep the workpiece on the strip until the end of the process.

Although metal scrap can be recycled, this method may not be cost-effective when processing copper or brass.

Four-slide/multi-slide Presses

A four-slide or multi-slide stamping press is a process that uses several dies and tools to stamp parts from wire coil or slit coil feedstock. The dies are attached to slides placed next to each other and move horizontally in four directions (more directions for multi-slide stamping). This allows complex shapes to be produced.

When a four-slide machine is first started, a roll of metal is placed. The machine then stamps and shapes the metal through a set of manually moving cams. Once the stamping and shaping is complete, the part is removed from the press and moves on to the next step in the production process.

Four-slide/multi-slide Presses

Advantages of Four-Slide/Multi-Slide Stamping Presses

Four-slide and multi-slide stamping is superior to standard progressive die stamping in many ways.

Complex Parts Can be Manufactured

Four-slide presses work horizontally at right angles and can make complex or multi-part corners, even corners greater than 90°. Multiple folds, bends, cuts or punches can be made in a single step.

Burr Side Selection

You can choose whether the cutting burr is on the top or bottom of the strip because the pressure generated can come from any direction.

Less Waste

Four-slide and multi-slide tools save significant money by reducing scrap metal by an average of 31%. Thanks to this process, no test holes are required.

It has slotted billet holders that allow parts to be moved from one stage to the next without guides. In addition, obtaining raw materials of a specific size is simple.

Quick Adjustment

All molding processes are controlled by a camshaft, which means that molds can be changed quickly and precisely without having to be removed from the machine. Less time is spent in the tool room and during breaks.

Flexibility

By changing molds, the same machine can produce different parts. This saves a lot of time in processing different items of metal parts.

Faster and Cheaper

Four-slide stamping can produce up to 375 parts per minute, which is typically faster than progressive die stamping presses. This makes it ideal for mass production.

Disadvantages of Four-Slide/Multi-Slide Stamping Presses

Despite the obvious benefits of four-slide and multi-slide stamping, there are some problems.

Long Setup Times

Setting up a multi-slide press takes longer than setting up a progressive die press because they are more complex.

Limited Material

Due to the construction of four-slide and multi-slide stamping presses, they can only be used with thin, pliable metal strips. This means they cannot be used for all tasks. Progressive die stamping is often the best way to make larger parts.
