Application Methods – Detailed Instructions

Method 1: Electric Branding Iron Holder (Recommended for Consistency)

Equipment Needed:

• Hot stamping machine (like ZHENGFEI WT-90XTS, EC-17, EC-27)
• Branding iron with threaded shank
• Temperature controller

Setup:

1. Install branding iron in machine’s mold holder
2. Set temperature based on material:
   • Softwoods (pine, basswood): 280-320°C
   • Hardwoods (oak, walnut, maple): 320-380°C
   • Leather (veg-tan): 180-220°C
   • Cork/Bamboo: 250-300°C
3. Wait 3-5 minutes for brass head to reach temperature
4. Test on scrap material first

Advantages:

• Consistent temperature (±5°C)
• Repeatable results for production runs
• Hands-free heating (work on positioning while heating)
• Safety (no open flames)
• Pressure control via machine lever

Technique:

• Position material on worktable
• Lower heated branding iron onto surface
• Apply steady pressure via machine lever
• Hold for 5-15 seconds (varies by material & depth desired):
  • Light mark: 5-8 seconds
  • Medium brand: 8-12 seconds
  • Deep/dark brand: 12-18 seconds
• Lift straight up (no dragging)

Method 2: Open Flame Heating (Traditional/Portable)

Equipment Needed:

• Propane torch or camping stove
• Branding iron with wooden handle
• Heat-resistant gloves
• Fire extinguisher nearby

Heating Process:

1. Light torch or stove (medium flame, not full blast)
2. Hold brass head 5-10cm above flame (not in direct contact)
3. Rotate branding iron continuously (prevents hotspots)
4. Heat for 2-5 minutes depending on head size:
   • Small (30mm): 2-3 minutes
   • Medium (50mm): 3-4 minutes
   • Large (70mm): 4-5 minutes
5. Temperature Test:
   • Spit test: Small water droplet should sizzle and evaporate within 1-2 seconds
   • Touch test: Approach bare wood – should lightly smoke when 2-3cm away
   • Target temp: 300-400°C for wood

Safety Precautions:

• Never heat wooden handle – keep at least 5cm from flame
• Use heat-resistant gloves (leather welding gloves ideal)
• Work in well-ventilated area (wood smoke)
• Keep flammable materials away
• Have water or extinguisher ready

Branding Technique:

1. Remove iron from heat
2. Work quickly (brass cools fast – you have ~20-30 seconds)
3. Position on workpiece (pre-marked if possible)
4. Press firmly and evenly (50-100N force)
5. Hold steady for 8-15 seconds:
   • You’ll smell wood burning (normal)
   • Light smoke is expected
   • Brass will slightly sink into softwood
6. Lift straight up
7. Immediate re-heat required for next branding (brass cools to <200°C in 60 seconds)

Advantages:

• Portable (no electricity needed)
• Traditional aesthetic/technique
• Works on large items that don’t fit on machine
• Outdoor use possible

Disadvantages:

• Inconsistent temperature (varies brand-to-brand)
• Requires practice to master
• Safety hazards (open flame, hot metal)
• Slower for production runs

Method 3: Induction Heating (Modern/Professional)

Equipment:

• Portable induction heater (like mini-ductor)
• Branding iron with ferrous metal content (brass with steel insert, or pure steel head)

Process:

• Place induction coil around brass head
• Heat for 30-60 seconds (depends on wattage)
• Temperature feedback via IR thermometer
• Very fast, very consistent

Note: Standard brass heads heat slowly with induction (brass is non-ferrous). Works best with steel-core custom heads.

Method 4: Wood Stove/Fireplace (Rustic/Large-Scale)

For Traditional Craftspeople:

• Place branding iron in wood stove embers
• Heat for 10-15 minutes
• Check temperature with water droplet test
• Suitable for large branding heads (conserves fuel)
• Very traditional method used historically

Caution: Difficult to control temperature precisely – risk of overheating brass (turns purple/blue, loses temper)

Material-Specific Branding Guidelines

Wood Branding

Temperature & Time by Wood Type:

Wood Preparation:

• Sand smooth (220-320 grit minimum)
• Remove dust with tack cloth
• Avoid oily woods (teak, rosewood) unless degreased
• Moisture content: 8-12% ideal (too wet = steam bubbles, too dry = scorching)

Pressure Guidelines:

• Softwoods: Light-medium pressure (brass sinks in slightly)
• Hardwoods: Firm pressure (brass should not sink in)
• Plywood/MDF: Medium pressure, shorter time (glue can cause uneven branding)

Leather Branding

Temperature Range: 160-220°C (much cooler than wood!)

By Leather Type:

• Vegetable-tanned (tooling leather): 180-200°C, 3-5 sec

  • Creates darkest, clearest imprint
  • Depth: 0.5-1mm
  • Can add water/moisture before branding for deeper impression

• Chrome-tanned (garment leather): 160-180°C, 2-4 sec

  • Lower temp to avoid melting finish
  • Shallow impression (0.2-0.5mm)
  • Test on hidden area first

• Suede/Nubuck: 140-160°C, 2-3 sec

  • Very delicate – easy to scorch
  • Matts down nap rather than burning

• Full-grain oiled leather: 170-190°C, 3-5 sec

  • May need degreasing first
  • Oil can cause uneven branding

Leather Preparation:

• Wipe clean with damp cloth
• For veg-tan: Can dampen slightly for deeper brand
• Avoid heavily finished/coated leathers (brand won’t show well)

Pressure:

• Light-medium pressure only
• Leather is soft – too much pressure creates indentation beyond brand area

Cork Branding

• Temperature: 250-280°C
• Dwell Time: 6-10 seconds
• Depth: 0.5-1mm (cork compresses easily)
• Notes: Cork is very forgiving – brands easily with good contrast

Bamboo Branding

• Temperature: 300-330°C
• Dwell Time: 10-15 seconds
• Notes: Similar to hardwood, burns to dark brown/black
