Molded doors are made by softening 4–6 mm medium-density fiberboard (MDF), then laminating it with a layer of melamine-impregnated decorative furniture paper, and hot-pressing it into shape in a mold in one step under high temperature and pressure.
The functional features and performance indicators of general PVC molded doors are as follows:
Scratch Resistance
PVC: Poor
Melamine: Super scratch-resistant
Environmental Performance
PVC: Difficult to degrade
Melamine: Recognized as environmentally friendly in European countries
Cost
Relatively low; melamine doors are not more expensive than PVC doors
Decorative Effect
PVC: Average printing effect
Melamine paper: Superior printing effect to PVC
Production Efficiency
PVC: Complex processes
Melamine: One-step molding within 3 minutes
Equipment Investment
Engraving machine, vacuum laminating machine, press, boiler, molds
Customization
PVC: Freely engraved by computer
Melamine: Shape fixed only by molds
UV Resistance
PVC: Poor
Melamine decorative paper: Light resistance up to Level 6
Process Complexity
PVC: Many processes
Melamine: One-step molding, suitable for mass assembly-line production
Impact Strength
PVC: Remaining thickness after engraving is 3–4 mm
Melamine: Maintains original panel thickness, internal fiber structure uncut, excellent impact strength
Formaldehyde Emission
Combined formaldehyde content from the board and laminating adhesive is greatly reduced after high-temperature and high-pressure processing.
