The stamping press is a century-old method of production that has been around since the dawn of humankind. The stamping press has been used to make all kinds of tools and weapons for ages, and even in this era, it is still a reliable production method for metal sheets or tough plastics.
Hundreds of years of development have made the stamping press a diverse field, with different types of stamping presses and dies for different projects. In order to design the perfect stamping press production line, you will need to know which type of stamping press and dies that go well with your products.
What is a Stamping Press?
The stamping press is a production method mostly used for sheet metals, but also for some tough plastic materials as well. In this process, engineers will pass metal sheets through the stamping press machine, which is made of presses and dies. The dies are arranged in such a way that resemble the finished products. When the metal sheets go through the machine, pressure from above, or even below, will be applied to the sheets, bending them to a shape resembling the dies. The metal sheets will then go through other stamping press stations until they become finished products.
Why Choose Stamping Press?
Stamping press is an age-old method, so most people understand how it works. This means that it will be quite easy for you to find workers and engineers who work in this field, making it possible for you to expand your workshop rapidly.
Another thing to consider is that the stamping press is a reliable way to work with metals. Even though injection molding can work with some metal materials, it is most effective when used with thermoplastics and resins. Thus, if your business deals with mostly metal materials, a stamping press is a good choice.
Different Types of Stamping Presses
As stamping press becomes more and more advanced, the types of stamping presses you can choose from have also expanded as well. Each stamping press comes with its own set of benefits.
Hydraulic Presses
Hydraulic presses are perhaps the most popular of all presses. Using liquid pressure (usually from oil), hydraulic presses apply very strong pressure to the baseplate that pushes downward, bending and distorting the metal sheets. Hydraulic presses are extremely powerful and capable of crushing even diamonds, so they are used for the toughest materials and tasks like forging or deep drawing.
Pneumatic Presses
Pneumatic presses use air or gas pressure instead of liquid pressure to apply force, so it does not have the powerful punches that hydraulic presses possess. However, they work very quickly and are capable of completing lightweight tasks such as punching and embossing with ease, so they are still very capable assets you could have.
Mechanical Presses
True to their namesake, mechanical presses use mechanical contraptions to power the pressure on the metal sheets. The driving force behind these presses are flywheels, which accumulate energy through rotations. When they have accumulated enough energy, the flywheels discharge it into the ram, which brings down pressure to the metal sheets.
Mechanical presses are highly efficient and accurate. It does not require much manual labor, and the operator can control the speed as well as the force applied fairly easily.
Servo Presses
Servo presses are a bit of a mix between mechanical presses and hydraulic presses. They use servomotors to power the hydraulic presses, which automate the process and speed it up considerably. As a result, servo presses come with both the speed of mechanical presses and the power of hydraulic presses.
Different Types of Dies
After you have settled on your type of stamping press, it’s time to take the dies into consideration. Different types of dies will be useful in different situations, so it’s important to know which one fits your project the most.
Progressive Stamping Dies
This is the classic type of dies that most factories would use. In this type of dies, the metal sheets will go through one stamping press after another until they look like the finished products. You have to set up multiple stamping stations for this kind of dies, but there is much less risk of mass defects.
Transfer Stamping Dies
Transfer stamping dies is pretty much similar to progressive stamping dies. However, instead of cutting out the parts at the end station, in transfer stamping dies, the parts will be cut out before the sheet metals go into the first station.
Single-Station Stamping Dies
Stamping press can also be done in just one station, but this is generally reserved for simple parts with not much complexity. This type of die is ideal for blanking and piercing.
Combination Stamping Dies
This type of stamping dies is the most complex single-station stamping die out there. It combines multiple machines and tools to accomplish difficult tasks such as blanking, piercing, forming, and bending. It takes a lot of investment and skills to handle these stamping dies.
Plastic Injection Mold
Stamping press is the method of choice for metal sheets and tough materials, but injection molding is still one of the most viable choices for manufacturers who wish to take on high-volume orders. Before you start an injection molding production line, you will have to take into account the plastic injection mold design. One single defect from the mold will lead to mass defects down the line. For this reason, please contact us at KuiXing Shanghai to find the best plastic molds or tools to get started.
Conclusion
There is a huge variety of stamping presses and dies, from hydraulic presses to servo presses and combination stamping dies. As the technical specifications and the purposes of these stamping press types differ greatly, you should always conduct a thorough analysis to make sure that you can find the perfect type of stamping press or dies for your business.
