What is Metal Stamping and its Benefits

Metal stamping is a manufacturing process that converts metal sheets into different shapes. The process is complex and it includes several metal forms and techniques. The techniques include blanking, punching, bending, and piercing just to name a few.

Many US companies offer these stamping services for industrial size pieces and tools. They also produce large quantities of complex parts. The stamping process is considered the best and cost-effective when it comes to large quantity manufacturing needs. For manufacturers who need these types of stampings, they look for Durability, low cost, and fast timing.

Stamping which is also known as pressing is when you use a flat sheet of metal which will be either a coil or blank form in a stamping press. Before the material can be done stamping professionals use design tools through engineering technology. These designs have to be precise to ensure each shape is properly measured to get the best results. The designing tools are usually 3-D models and can contain hundreds of parts which is what makes the process very complex.

There are four types of metal stamping which include, progressive die stamping, four-slide, and deep draw. All of these stampings are unique and highly used. These designs are usually featured in numerous workstations and possess unique functions.

Progressive die stamping

Progressive die stamping is when strip metal is fitted through a progressive stamping press. The strip carefully unrolls from a coil into a die press. Each tool in the station uses a different cut, punch, or bend. Due to the complexity of this stamp press manufacturers may have to continuously change the tool because each tool is performing one action required for that part. Progressive die stamping is considered the most common use because it has a fast turnaround, shorter run length, and lower labor costs.

Deep draw stamping

The deep draw is when you pull a sheet of blank metal into the die via a punch. This is the way it is formed into a shape. This method is considered deep drawing and is when the depth of the drawn part exceeds its diameter. This type of Stamping is ideal for components that need several series of diameters. This is also a cost-effective stamping and is also an alternative to the turning process which would use more raw material.

Four slide Stamping

Four slide stamping also known as multi-slide has horizontal alignment and four different slides. There are four tools that are used at the same time to shape the piece. In this process, manufacturers can create intricate cuts and complex beams that develop into even more complex parts. This type of technique is best for versatile parts and more flexibility.

Short-run stamping

Short-run stamping may be best for prototypes and small projects. The reason being is that it requires minimum tool expenses. After the blank is created, manufacturers combine custom tools and die inserts to bend, punch, or drill the part. This stamping technique is more cost-efficient due to the absence of a tool cost and has a swift turnaround. Since it is a custom forming operation and smaller run size, there is a higher per piece charge.

Lastly, metal stamping is for industrial parts. The technique includes blanking, punching, bending, and piercing. There are four types of these stamping which include deep draw stamping, four-slide stamping, progressive die stamping, and short-run stamping. All of these are very cost-efficient and make tools and parts quickly. Although, there is a quick turnaround the process is very complex. These stamping techniques are great for creating large quantities of parts.

Marking or engraving? This is the dilemma: Three criteria to avoid making the wrong decision

Published

Laser engraving

In the previous article, we explained the fundamental differences between laser marking and laser engraving, which are often wrongly confused. In marking, the laser melts the material through heat and modifies its shape to imprint a permanent code or mark.

Laser engraving, on the other hand, vaporizes the material. The laser beam penetrates deeper into the surface and removes the upper layers by sublimating them, or rather through a direct transition from solid to a gaseous state. This is because the laser hits localized areas with a high intensity of energy and therefore heat.

But how do I choose whether to mark or to engrave?

Now that we understand the difference between the two processes, let’s now define what are the main parameters that lead us to choose one over the other:

1 Marking resistance

Laser engraving penetrates the surface more deeply and is recommended for all those components that are at risk of wear due to the environmental conditions in which they will be set, or that are subjected to post-marking process surface treatments such as sandblasting, shot peening, e-coating or heat treatments

2 Speed

Marking is a process that takes less time than engraving, precisely because it penetrates the surface of the material less deeply. If the component is not subjected to a particular stress, such as with home appliances, electronic, promotional, and jewelry components, marking also guarantees speed mixed with the permanence of the result.

3 The material and its compatibility

As already explained, while marking dissolves the material by modifying its roughness, engraving sublimates the material by creating grooves. To do this, the laser must be powerful enough to vaporize the material in a few milliseconds and the material to be marked must have an adequate sublimation temperature, so deep engraving is not always possible.

When laser engraving occurs, it is important that the laser marker is equipped with a suitable exhaust system. LASIT has designed its exhaust fan, specifically designed to maximize the level of protection of both the environment and the laser itself.

Now that we have a more precise picture of the parameters that lead us to recommend one rather than the other process, it is time to find out about the 10 guidelines for choosing a good laser marker.

What are the steps involved in Lanyard design?

printing of lanyards Singapore

Lanyards are not a modern invention. It was invented in France right back in the 18th century for the soldiers to tie the weapons on to a chord so tight that they can use it often. The design, technique of production, and purpose of the lanyard have undergone a drastic change over the years. These are some of the steps involved in Lanyard design.

The printing of lanyards Singapore follows these steps to design a lanyard.

Step 1: Use a proper tool to design 

There is a lot of software available in the market using which you can design some of the best designs for a lanyard. Hire a designer and get it done.

Step 2: Choose the right production process 

You might think that all the production process is the same. But this is not the scenario. Certain production techniques may work for certain items and certainly don’t.

To understand which would work for what, you need to have an understanding of the processes.

Screen Printing  

Screen Printing is a process originated in China back in the 6th century and later it spread to Japan. This process involves pouring ink on a mesh screen which has the logo of your company impregnated on it and the lanyard fabric is placed underneath the mesh and thus, the logo gets created.

Also, you can place the lanyard fabrics which are cut to the desired size, and then you can place the mesh on top of it. The width of the mesh should be the same size as the width of the lanyard fabric.

The paint on top of the mesh is scraped off so that the paint gets stuck to the fabric in a much better fashion.

You can place a silicone sheet on top of the lanyard fabric and then provide some heat on top of the sheet so that the image gets stuck.

Dye Sublimation 

While Screen Printing just involves printing the image on top of the fabric, the dye-sublimation method incorporates a process where the dye is impregnated into the lanyard fabric and the color stays longer.

The design is coded on to the sublimation machine and the heat transfer paper is placed in such a manner that the reverse image gets printed on the sheet of paper. This sheet of paper now transfers the images on it to the lanyard fabric. A high temperature is required to complete this process.

There are other post-production processes like cutting the lanyard fabric to its length. Analyzing the quality of the finished product etc.

These are some of the steps involved in Lanyard design. These techniques are tested from time to time and have shown better output due to the efficient processes involved in it.
