Thermopatch HS-21-SQR Manual Heat Seal Press for Labels and Patches
Square format heat seal press
The Thermopatch HS-21-SQR is a compact and portable manual heat seal press designed for applying labels, patches, transfers, and emblems to textiles. Ideal for dry cleaners, commercial laundries, hotels, uniform services, and garment marking operations processing small and medium-sized batches, the HS-21-SQR features two press platens for quick application of heat seal labels. With accelerated warm-up time of less than one minute and full digital control via graphical display, this energy-efficient heat seal machine requires no compressed air and operates at under 70 decibels. The 120 x 120 mm sealing plates provide versatile application capability with temperature control from 50 to 225°C and adjustable timer from 0 to 240 seconds. Weighing just 16 kg, the HS-21-SQR is supplied in South Africa by Unicorp for professional garment identification and marking applications.


Compact heat seal press with digital control for fast label application
The Thermopatch HS-21-SQR offers the latest heat sealing technology in a compact and portable design suitable for operations with limited floor space. The two press platens allow quick application of heat seal labels, patches, transfers, and emblems to garments and textiles. The graphical display provides clear indication of current press status including real-time temperature and heat seal time, ensuring operators can monitor the sealing process accurately. Accelerated warming brings the sealing plates to operating temperature in less than one minute, reducing idle time and improving productivity. The energy-saving sleep mode automatically reduces power consumption during periods of inactivity, lowering operating costs. Operating without compressed air eliminates the need for air compressor systems, simplifying installation and reducing facility requirements. The quiet operation at under 70 decibels makes the HS-21-SQR suitable for use in customer-facing environments such as hotel laundries and dry cleaning reception areas.
