Curing Station Setup and Maintenance Workflow

Conveyor Dryer (Inline Curing)

• Garments pass under heated IR lamps or circulating hot air
• Temperature range: 200–400°F
• Dwell time: Adjustable via conveyor speed (typically 60–120 seconds)
• Best for: Pretreatment, screen print flash curing, water-based ink curing
• Cost: $2,000–8,000 for entry-level; $8,000–20,000+ for industrial

Heat Press (Batch Curing)

• Heated platen applies fixed pressure to garment for set duration
• Temperature range: 250–450°F
• Dwell time: Fixed via timer (30–180 seconds)
• Best for: Final DTG curing, specialty ink curing, sublimation
• Cost: $500–3,000 for commercial; $3,000–10,000+ for high-volume

Spot Cooler or Fan

• Accelerates cooling between production runs
• Reduces idle time and increases throughput
• Essential for shops running high-volume production

Conveyor Dryer Calibration

1. Place infrared thermometer probe on garment bed under heating element.
2. Set dryer to target temperature (e.g., 320°F for pretreatment).
3. Allow 15–20 minutes warm-up time for stable reading.
4. Check temperature at entry, middle, and exit zones.
5. Adjust heating element controls if zones vary > 10°F.
6. Record calibration date and results.

Heat Press Calibration

1. Place IR thermometer on heat press platen.
2. Close press without garment; allow 10 minutes warm-up.
3. Set press to target temperature.
4. Verify actual temperature matches display (often ±20°F error).
5. If error > 20°F, contact manufacturer for element replacement.
6. Test with a garment sample and visual inspection.

Conveyor Dryer

• Warm-up: 15–20 minutes before production
• Conveyor Speed: Slower = higher dwell time = more curing. Typical range 2–6 feet per minute. Adjust in 0.5 FPM increments.
• Spacing: Leave 2–3 inches between garments to allow airflow.
• Garment Loading: Load garments flat, not wrinkled or bunched.
• Monitoring: Check temperature hourly with IR thermometer; log readings.

Heat Press

• Warm-up: 10–15 minutes before production
• Pressure Setting: Full pressure is standard (usually 2–3 tons clamping force). Reduce only for delicate fabrics.
• Dwell Time: Use timer; don't estimate by feel. Start at recipe (e.g., 60 seconds at 320°F) and adjust based on results.
• Cooling: Open press between garments to allow slight cooling; prevents heat buildup.
• Safety: Never force press closed; if resistance is high, check garment positioning.

Daily

• Visually inspect heating elements for dust or debris
• Check temperature accuracy with IR thermometer
• Clean garment bed or platen with soft cloth
• Empty garment baskets; organize workflow

Weekly

• Vacuum dust from conveyor dryer intake and exhaust
• Wipe heat press platen with damp cloth; dry thoroughly
• Check conveyor belt tension (should not slip under load)
• Test emergency stop button

Monthly

• Deep clean heating elements (use compressed air, never water)
• Calibrate thermostats against reference thermometer
• Check electrical connections for loose wires
• Lubricate conveyor belt bearings (if applicable)

Quarterly

• Replace air filters in conveyor dryer
• Inspect heating elements for cracks or discoloration
• Test temperature uniformity across entire heated area
• Check for thermostat drift and recalibrate if needed

Temperature Won't Hold Steady: Thermostat calibration drift. Recalibrate or replace thermostat.

Hot Spots or Cold Zones: Uneven heating element coverage. Check for debris blocking airflow; clean or replace heating element.

Conveyor Not Moving: Belt tension too tight or bearing seized. Adjust tension or lubricate bearing.

Garments Under-Cured: Dwell time too short, temperature too low, or incorrect chemical ratios. Increase dwell time 10–15 seconds or raise temperature 10°F.

Garments Over-Cured (Yellow/Brown): Temperature too high. Reduce by 10–15°F and test again.
