HD Press 3624 Vacuum Former Press


In Stock

The HD Press 3624 Vacuum Former Press - an innovation to membrane vacuum forming technology. The HD Press 3624 is made out of highly durable ABS plastic, ready for daily frequent use. It is the only kydex vacuum former press of its kind.

This model is our new Gen II design and replaces our previous acrylic vacuum press model the HD 300.  Over a year of engineering, design, and testing has resulted in this new series of Gen II HD vacuum formers. 

With the use of a heat-sink over the dual ported vacuum grid, the press can stand up to repeated, back to back, all day thermo-forming. Using ultra durable membrane secured to the top of the press by strong neodymium magnets, the HD Press has the easiest to replace membrane on the market.

The HD Press 3624 space conscious design has built in plumbing for a plug and play application. All you have to do is hook up your vacuum pump and get started. The HD 3624 is designed to have as little air volume as possible to apply a quick vacuum to a hot work piece. With these built in features and its ease of use, the HD Vacuum Press sets a new industry standard.

The HD vacuum press is a premium leak proof design with an ultra sleek look. Integrated is a vacuum release vent, and an easily removable lid. Unlike other standard materials used on traditional presses such as wood and PVC this Vacuum Former is crack resistant. You won't find quality like this elsewhere!

Industries used in - dental, aerospace, special effects, military, Holster Making, Knife Sheath Forming, Hobbyists, Cosplay, Costume Makers, Orthotics, small prototyping and many other types of thermoforming. Different materials thermoformed on the HD Press -  Kydex, Boltaron, ABS, HIPS, PETG, Wonderflex, Worbla, Styrene, Cork, Leather, Plastics, and other types of thermoformed & vacuum formed materials.

Ask a Question
  • What else do I need to buy to get started?

    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.

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

    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. Robinair 15800 VacuMaster 8-CFM Two-Stage Vacuum Pump. Robinair 15500 VacuMaster 5-CFM Two-Stage Vacuum Pump. Robinair 15310 VacuMaster 3 CFM Single Stage Pump. Be sure to check out our Automated Vacuum Control System for a fully automated streamlined solution.

  • Will this work for leather holster forming?

    Yes. Many of our users are leather forming with the HD Press.

  • How much vacuum is required to form kydex?

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

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

    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. Watch this video on how to do that - Click Here

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

    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

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

    Check the membrane for dirt and clean it with a damp sponge. A dirty membrane can effect the seal. 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.
