Double-Head Coating Machine

The dual-head coating machine applies liquid materials onto a substrate surface synchronously or alternately through two independent coating heads, utilizing blades or rollers to control the coating thickness. It is used in laboratories to simulate printing and coating processes, and to test properties such as coating adhesion and hiding power. It is suitable for parallel comparative testing of materials such as ink paper and plastic films.
Selection
When selecting, consider the compatibility between the substrate thickness range and the coating width, ensuring the coating thickness adjustment accuracy meets testing standards. Choose between blade coating or roller coating based on the sample viscosity, with heating functionality for coatings requiring baking. The equipment material should be resistant to solvent corrosion, and operational stability affects coating uniformity.
