II. Product Details (PRODUCT DETAILS)

1. Fine-Caliber Tungsten Steel Nozzle, Precision Surpassing Traditional Spray Guns

(1) Three Calibers Cover All Precision Scenarios

• 0.5mm Ultra-Precision Nozzle: Designed for model making, with atomized particles ≤20μm and spraying width ≤5cm. It can accurately outline 0.2mm-wide model lines (e.g., Gundam model textures), and the coating thickness can be controlled at 5-8μm without graininess;
• 0.8mm Regular Precision Nozzle: Suitable for electronic component touch-up (e.g., mobile phone middle frame paint chipping) and craft painting, with spraying width 8-10cm and coating thickness 10-12μm, balancing precision and efficiency;
• 1.0mm Small-Area Primer Nozzle: Ideal for low-viscosity primer on small workpieces (e.g., anti-rust primer for metal badges), avoiding blockage and meeting protection needs with one spray.

(2) Tungsten Steel Material + Mirror Inner Wall, Enhanced Durability

2. Small-Capacity Cup + Lightweight Design, Easier Operation

(1) 125mL Small Capacity, Eliminating Coating Waste

(2) 350g Lightweight, No Fatigue in Long-Term Use

3. Low-Pressure Environmental Protection + Wide Adaptation, No Scene Restrictions

(1) 43 PSi Low Pressure, Usable at Home

(2) Compatible with Multiple Air Sources + Coatings

• Air Source Adaptation: The G1/4" interface can be connected to household air compressors and rechargeable portable air compressors, meeting the needs of outdoor model spraying;
• Coating Compatibility: Compatible with model paint (nitrocellulose paint, water-based paint), electronic component-specific paint (insulating paint, conductive paint), and craft paint (acrylic paint). Only the nozzle needs to be replaced and the gun body cleaned, with no need to purchase additional dedicated equipment.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Precision Coloring in Model Studios (Core Scenario)

1. Preparation: Install the 0.5mm nozzle, pour 15mL of camouflage paint, adjust air pressure to 42 PSi, and test atomization (3cm narrow fan shape);
2. Spraying: Use masking paper to cover non-camouflage areas, keep the nozzle 10cm away from the model, move at 15cm/s to spot-spray along textures, and spray 3 colors step by step, taking 20 minutes;
3. Cleaning: Rinse the gun body with thinner after each color change to avoid mixing.
   Result: No blurring at camouflage edges, 8μm coating thickness, clear model details, 78% coating utilization rate (only 3mL wasted), and 5 times higher efficiency than brush coloring.

2. Mobile Phone Shell Touch-Up in Repair Shops (Scenario 2)

1. Pre-Treatment: Sand the chipped area with 2000-grit sandpaper, pour 5mL of touch-up paint, and adjust air pressure to 43 PSi;
2. Touch-Up: Cover other areas with masking film, apply 3 thin coats (5-minute interval between coats) with the nozzle 8cm away;
3. Finishing: Polish with 3000-grit sandpaper after the touch-up paint dries, and clean the gun body.
   Result: The color difference between the touched-up area and the original paint is ≤ΔE1.5 (invisible to the naked eye) with no graininess. Customer satisfaction reaches 98%, and touch-up time is reduced from 30 minutes to 10 minutes.

3. Coloring Resin Crafts for DIY Enthusiasts (Scenario 3)

1. Debugging: Install the 1.0mm nozzle, pour 10mL of enamel paint, and test atomization on a waste resin sheet;
2. Gradient Spraying: Move from the top to the bottom of the pendant, gradually reducing trigger pressure to achieve a gradient effect (darker top, lighter bottom) in 5 minutes;
3. Storage: Rinse the gun body with alcohol, disassemble the cup for storage.
   Result: Natural gradient transition, glossy coating, and successful operation for beginners, solving the pain point of "uneven manual coloring".

IV. Frequently Asked Questions (FAQ)

Q1: The nozzle is blocked (no paint sprays out). How to solve it?

1. If the coating is undiluted (viscosity ＞15s): Add a dedicated thinner (water for water-based paint) to adjust to 8-12s viscosity;
2. If residual paint is dry and hard: Unclog the nozzle with the included needle, then rinse 3 times with thinner;
3. If there are impurities: Filter the coating through a 200-mesh sieve before pouring into the cup.
   Prevention: Clean the gun within 10 minutes after each use, and thoroughly clean the 0.5mm nozzle with the needle.

Q2: The small cup requires frequent refueling, which is troublesome. Any optimization methods?

1. Batch preparation: Calculate the required amount in advance (e.g., 15mL per camouflage color for models), and pack 2-3 portions in small measuring cups. Refueling only takes ＜10 seconds by pouring pre-prepared paint;
2. Accessory expansion: Purchase a 125mL cup extension adapter (50mL/100mL) to increase the total capacity to 225mL, suitable for batch spraying (e.g., multiple resin pendants).

Q3: There is "overspray" when spraying with the 0.5mm nozzle. How to adjust?

1. Excessive air pressure (＞42 PSi): Turn the pressure regulating valve counterclockwise to 38-42 PSi until the spray pattern is compact without overspray;
2. Too far nozzle distance (＞12cm): Shorten to 8-10cm and move at a uniform speed of 15-20cm/s;
3. Too low coating viscosity (＜8s): Add a small amount of undiluted paint to increase viscosity.

Q4: Can a household rechargeable air compressor (0.1m³/min) be used?

1. Short-term use (＜10 minutes): Fully charge the battery and use the "30s spray + 10s pause" intermittent mode to avoid pressure drop;
2. Long-term/batch use: Replace with an air compressor of ≥0.15m³/min. Otherwise, the air pressure will drop below 38 PSi, leading to coarse atomization, and frequent start-stop of the compressor will shorten its service life.
