Question
I am currently searching for a machine to laminate vinyl onto various substrates, including MDF and gypsum. I was looking at the Harlan equipment, but I am confused about what I really need... Hot press, cold press, HPL...? We are launching a new product soon and this is really holding us up.

From contributor M:
A vacuum press with heaters works the best for vinyl. It becomes soft and compliant and works well with the adhesive. All the air will be sucked out with a good vacuum press. The equipment we manufacture is prefect for what you want to do.
As for the discussion about thermofoil doors and positive pressure, up until April of this year I had been working for an adhesive company selling into the 3D thermofoil components industry. Our tech support calls went through the roof anytime someone installed a vacuum only machine. Anyone trying to do thermofoil doors on melamine backed material will have to pre-drill holes through the melamine in order to even get halfway decent definition. If not, you'll be using a heat gun after the parts come out of the press to try to get the vinyl to collapse into the profile. The problem is the glue has already started to cure so you never really know if you have any bond in the profile.
Don't believe me? Then go to Miami, FL where you can see a few dozen of these machines in operation. You'll likely see the heat gun pulled out at every installation you stop at. Then ask to peel the vinyl back from one of the doors and notice the bond, or lack of bond, in the profiles.
Vinyl coated doors were becoming popular in the early 1990’s and membrane presses like the one in this string started to pop up and some are very nice. If a customer was to go in business making doors to sell, or required a high volume, or wanted to make wood veneer raised panel doors, then a press with top pressure, a membrane press, is the way to go. However, the making and selling of doors is a very saturated market, you can buy them cheaper than you can make them.
The Multi Vacuum press is for small- to mid-sized shops who want to make their own custom components, like for schools or apartments or even custom kitchens. Making your doors with melamine on the back side is the way to go. If you have a really deep detail, then drill your hinge holes first - you need them anyway. And there are adhesives just for vacuum pressing as well as pre-applied adhesives. I promise everyone that no heat gun will be needed.
If you're only making 50 parts a day, what on earth are you doing making your own parts? You're never going to get familiar enough with the process (effects of temperature changes, different materials, profiles, etc.) to be any good with it. Hey, just buy from one of those vacuum former operators selling for $3.00 ft2. But, make sure you buy one more part than you need and rip it to see if I'm telling you the truth.
