Heat press machines transfer designs onto garments using heat and pressure. They are widely used for vinyl transfers, sublimation printing, and specialty finishes like glitter or metallic. Clamshell presses are easy to use and great for beginners, while swing-away presses allow more workspace and even pressure ideal for thicker materials. Automatic heat presses are designed for high-volume production, reducing manual labor and increasing efficiency. Each type offers unique benefits depending on the project size and production needs.
