This machine is much better than the brand I was using before. The working area is huge and operation simple. The ease of use with the magnets for the membrane is genius. We had the product exactly when they said we would and we immediately got to work. I thought I was gonna hate the idea of custom drilling holes in the board but it turns out....? I didn’t!! Should have gone with HD Industrial first!!!

The best vacuum former on the market

We have never had an issue with the vacuum former. We use it on our production runs of 100 or more molds at a time. Would highly recommend to any new or established company wanting to upgrade their production methods.

Fits my needs

As expected, when I took delivery and set it up, this fit my needs perfectly. This is by far the best designed vacuum former I have seen to date.

First Rate

Looks and feels like first-rate equipment. The quality that one achieve with this press is likely near the best available for membrane-based vacuum forming. Hero Holsters is proud to be using HD Industrial equipment in our recent production expansion, and will be back for more as need dictates.

Great Design

After working with their smaller vacuum press we knew we had to add this to our line. Great design and works perfect. Thank you guys.

Very Nice

The unit works very well. I was able to form up a sheath for a machete no problem. handles large objects quite easily, and multiple forms at one time if desired.

Q: What else do I need to buy to get started?

A: All neccesary fittings and tubing are included with each press. All you will need to purchase separately is a Vacuum Pump. If you plan to plumb directly to your vacuum pump we recommend adding a Check Valve to prolong the life of your pump. The Automated Vacuum Control System includes one in the kit. We also recommend getting an Extra Membrane for a backup.


Q: What CFM vacuum pump do I need to operate the HD Press?

A: All HD Vacuum Presses will work with any 3-CFM pump. We recommend the following pumps. Based on what you are pressing you will have to decide which will work best for you. 8-CFM Two-Stage Vacuum Pump. 5-CFM Two-Stage Vacuum Pump. 3 CFM Single Stage Pump. Be sure to check out our Automated Vacuum Control System for a fully automated streamlined solution.


Q: My HD Press won't hold vacuum when I close the valve. How can I troubleshoot and fix this?

A: Check the membrane for dirt and clean it with a damp sponge. A dirty membrane can effect the seal. Check for holes in your silicone membrane. If you have formed anything with sharp edges that were not properly covered the silicone membrane can be punctured. Take the heat sink off the press, wet your thumb and place it over the port and pull a vacuum. This will narrow down where the leak is. If the vacuum holds with your thumb over the port, then you can rule out the plumbing. If it doesn't, then the leak will be somewhere between the port and your pump. Check all the plumbing connections to make sure they are securely seating in the fitting. If you can't find the source after this, please contact us for help.


Q: How much vacuum is required to form kydex? 

A: Most of the time all you will need for Kydex to form for knife shealths and gun holsters is around 27inHG.


Q: Will this work for leather holster forming?

A: Yes. Many of our users are doing leather holster forming with the HD Press.


Q: The vacuum pump fitting doesn't match the easy connect NPT parts supplied. How do I make it work?

A: You will have to remove the flared fitting that your vacuum pump comes with standard and replace it with the 1/2" or 3/8" easy connect fitting supplied with your press depending on model. Most vacuum pumps are ACME threaded which is a little different than NPT. Once you remove the standard fitting it will rethread to work with the NPT included.

Q: I am looking for a vacuum former to make scale airplanes models, would this machine work for me? How does this machine heat up the material to be formed?

A: Our vacuum presses do not have built in heaters. You have to heat your material externally and then transfer it to the press to be molded. There are many different ways to heat materials depending on the type and thickness. Heat press, flash dryer, oven, toaster oven, etc.

Q: Do you recommend the Robinair 15310 for this press or is a larger compressor required?

A: Any 3CFM or higher pump will work. The 15310 is a great pump and works well with both sizes and particularly the 2424 model. Take a look at this blog post on choosing a vacuum pump - vacuum pump selection
