Please note: if you have an HD 200 press with plexiglass footing you will need to order membrane sold by the foot and cut it to fit. We no longer sell precut membrane for that size. (This only applies to a small number of our first presses from 2014).

Great Product

Super easy to work with. I’ve bought several of these over the years. They are very tough, each membrane lasts and last

HD 200 is awesome

Great product! Formed hundreds of holsters with HD200 and original membrane finally tore a little so I ordered a replacement. Super quick shipping. Prefect fit! Thanks HD!

Heavy duty high temp membrane.

The membrane arrived on time well packaged and intact. Upon opening it no defects were noted. I sprayed it with a food grade industrial silicone and installed it easily in the press. The cuts for the hinges were perfect. When molding it holds tight and gives fantastic detail to the kydex. A good product with zero issues.

The High Temp Membrane goes

The High Temp Membrane goes together with the HD200 Press. Being based in the UK I heard some horror stories about how the membranes tear, so I bought three. I am still on my first one and have formed a fair amount of holsters.

The HD industrial designs silicone

The HD industrial designs silicone membranes allow mic holster systems to press thousands of holsters before failure. These are of genius design. Very well worth the cost.

Great High-Temp Membrane

These membranes are the best for holding up to rigorous use. I would recommend them to anyone needing to make kydex style holsters. Thanks HD Industrial Design!

Q: How thick is the silicone membrane?

A: Our silicone is approximately 1/32" thick.


Q: What is the temperature rating?

A: It is rated over 400 degrees.


Q: Would I be able to use it in my heat press over my kydex?

A: It is rated over 400 degrees and should be fine for use on your heat press with kydex.


Q: Can I use a larger membrane than what comes with my HD Vacuum Press?

A: HD vacuum press membranes are not interchangeable between different models. HD Presses are only designed to function correctly with the size membrane made for that specific HD vacuum press model. Using a larger/looser membrane than intended will result in a bad vacuum seal, broken magnets and can potentially damage your press. We recommend selecting a larger HD Vacuum Press if you are running into issues with the size of your workspace or reaching the limits of the membrane. You may also need to revisit how you are forming to see if you can reduce any excess height of your molds.


Q: Does the temperature of the work area affect the membrane? Let's say if my work space is cold but heated up during times of production, would the membrane wear out faster if it's not always warm or would it be more susceptible to tearing?

A: Temperature shouldn't effect performance...unless you are operating in sub zero conditions, this shouldn't factor in to the longevity and pliability of your membrane.
