The GS-804 is an automatic heat press designed primarily for sublimation and heat transfer printing on T-shirts and other fabric garments, as well as sublimation blanks.
The upper and lower platen size is 13.8" x 16.5" (350 x 420 mm), which corresponds to an A3-capable printing area for larger designs.
The GS-804 is an automatic-grade machine with an auto-open feature, and it also supports manual mold operation for flexible use.
It supports 120V at 12.5A or 240V at 6.5A, with a power consumption of approximately 1500W. Make sure your outlet and circuit can handle the specified current.
Maximum temperature is 221°C (430°F). Per specifications, it reaches about 160°C in ~16 minutes and about 180°C in ~25 minutes—actual times depend on voltage and ambient conditions.
Pressure is adjustable on a scale from 1–9. Set pressure according to material thickness and type; perform test presses to determine the optimal setting for your substrate.
The GS-804 is intended for sublimation blanks and polyester or polyester-coated fabrics (best results on high polyester content). It is also suitable for DTF sheet transfers; for dark cotton garments you will need appropriately coated substrates or alternate transfer methods.
The GS-804 is offered in blank & gray, mint blue, and pink color options.
With the platen open the machine measures approximately 588 x 363 x 473 mm. Machine weight is about 32.6 kg and packed weight about 37 kg. Check your bench depth and clearance for the open platen before purchasing.
Standard packing dimensions are listed as approximately 680 x 460 x 550 mm and packed weight around 37 kg. Actual packaging may vary by shipper.
Yes — the product description notes suitability for DTF sheet printing users. Always follow your ink/film manufacturer's recommended time, temperature, and pressure settings and perform test prints first.
Unplug and cool the machine before cleaning. Wipe the platen with a soft, lint-free cloth; avoid abrasive cleaners and solvents. Periodically check electrical connections, the silicone pad, and moving parts; replace wear items as needed.
The GS-804 includes automatic open functionality to help prevent overheating of garments. Always use heat-resistant gloves, keep hands and flammable materials away from the platen, ensure adequate ventilation, and never leave the machine unattended while powered on.
Warranty terms and availability of replacement parts vary by seller and region. Contact your supplier or the manufacturer (Galaxy Press) for warranty details, authorized service, and spare parts information.
Cycle time depends on material, ink, and recommended settings. As a general guideline for polyester sublimation, many users press around 180–200°C (356–392°F) for 30–60 seconds, but you should follow ink/paper/substrate manufacturer instructions and run tests to determine optimal time and pressure for your setup.
