Is a used stamping press better than buying one new? You may be surprised by how the pros outweigh the cons of buying a used stamping press. Particularly when it comes to saving money.
But how do you make sure you buy a stamping press that is still good quality? Start with this complete stamping press checklist.
Types of Stamping Press
Before we dive into aspects to be aware of before purchasing a used stamping press, let’s cover the three common types of stamping presses.
The mechanical presses have a motor connected to a mechanical flywheel. They have punches from 5mm to 500mm in size depending on the press you purchase. These tend to be faster than hydraulic presses.
They also come in a large range of sizes. The mechanical presses are used for creating shallower and simpler parts. They are best used for large production runs of progressive and transfer stamping.
These presses range in size from 20 to 6,000 tons. They offer a range of strokes per minute between 20 to 1,500.
The hydraulic presses use pressurized hydraulic fluid. This applies pressure to the metal or other materials with an advanced amount of control and consistency. They offer more adjustability when it comes to stroke and speed capabilities.
Hydraulic presses range in size from 20 to 10,000 tons. They come with stroke sizes from 10mm to 800mm. They are used for smaller production runs than the mechanical. They provide the most flexibility because of the adjustable stroke length and ability to control pressure.
This is typically the most expensive of all three presses due to their precision and speed.
The mechanical servo presses differ in that they use high capacity motors rather than flywheels. These are used when more complicated stampings are needed at a higher speed than the hydraulic press.
You can precisely program and control the stroke, motion, and slide position of these presses along with the speed. You can power the mechanical servo by a link-assisted drive system or a direct drive system.
Outline Your Needs
Before buying a stamping press, you should first find out what your shop’s priorities and needs are. Create a master list of everything your press is needed for on a routine basis.
Don’t be afraid to be highly detailed in your daily processes. Whether it’s punching, blanking, embossing, coining, bending, or flanging, make sure your machine is ready. Since this is a big purchase for your business, you want to make sure it will cover all your basis.
Get a Warranty
When looking for the right used stamping press for your business, the first thing you should look for is a warranty that will last for many months or more. This ensures that you’re protected if the used stamping press should happen to break or not work properly.
Before purchasing a stamping press, it’s important to look into the company selling the presses. Find out if they have a good reputation by looking into some company reviews. Some questionable businesses may sell poor quality items.
Be sure they have a good standing with their company and provide some testimonials on their website.
Versatility is Key
When choosing a press, it’s best to find one that will accomplish a variety of tasks that are needed for your shop. This means you can get more done by using fewer machines.
If you can find a stamping press that has many features you will need, it can save you the hassle of having to purchase another press later on.
When purchasing a used stamping press from a business, you can tell right away from their professionalism if they are a legitimate company. For example, look into the quality of their website and if they offer contact information. You should also check out their social media pages to see if they are active and responsive.
Are they Registered?
You should only be a used stamping press from a registered company. This ensures that the items are not stolen. This could be a very dangerous situation to get into if you purchase stolen items from a company that is not registered. Even if you were unaware they were stolen.
Even though you may be purchasing a used stamping press, it’s still worth finding one that is relatively new. That’s because a lot of the latest presses offer technology that allows you to complete the job faster and more effectively.
You may even be able to program your press using an electronic control panel. This allows you to increase your output speed without having to do it mechanically. It also ensures quality repeatability for each stamped piece.
Test for Accuracy
Before making a purchase you should test the machine for precision. You want your end results to be of high quality so be sure the used machine delivers. Plus, the more adjustability on the machine, the better.
Having an electrical discharge machining (EDM) and computer-aided design (CAC) programs will contribute to accuracy.
Research Part Replacement
You don’t want to invest in a machine that you can’t find replacement parts easily. This could result in unnecessary downtime. Newer machines make finding parts easier. Plus, they take up less space in your shop which is another way to increase efficiency and functionality.
Find the Right Used Stamping Press for You
No matter what your business, a used stamping press can save you money when you need to replace or purchase a machine. There are a lot of aspects to consider when purchasing a stamping press but with the right preparation, you can find one to suit your needs.
