The difference between a single layer heat press and a double layer heat press is:
1. Different structures: A single layer heat press machine has only one laminate, while a double layer heat press machine has two laminates.
2. The production efficiency is different: the double-layer heat press can heat press two parts at the same time, and the production efficiency is higher than that of the single-layer heat press.
3. Different scope of application: Double-layer heat press is suitable for mass production, while single-layer heat press is suitable for small batch production or trial production.
4. The prices are different: the price of a double-layer heat press is higher than that of a single-layer heat press.
5. Different floor space: Double-layer heat press occupies a larger area than single-layer heat press.
