Product Name

✅ Hand Push Diaphragm Pump Cold Paint Road Marking Machine

✅ Ambient Temperature Cold Spray Line Construction Equipment | Direct Factory Supply

Product Overview

✅ This cold spray marking machine is professional road line equipment built with high-pressure airless spraying technology.

✅ Its high-pressure diaphragm pump delivers up to 25MPa pressure, pushing marking paint through the spray gun onto pavement at high speed. The coating bonds tightly with the road base to form even, compact, high-adhesion traffic lines.

✅ Compared with brush coating and air spraying, airless high-pressure lines have fewer bubbles, stronger adhesion and superior wear resistance. It fits municipal roads, highways, parking lots and all kinds of traffic marking projects.

Core Features

✅ High-pressure airless spraying

⭐ Max working pressure reaches 25MPa to boost line adhesion and construction quality.

✅ Dense uniform marking film

⭐ Smooth compact coating without bubbles, hard to peel off pavement.

✅ High construction efficiency

⭐ Marking speed ranges 3–5km/h, perfect for large-area road projects.

⭐ Stable running performanceWide inflatable rubber wheels plus independent shock-absorbing chassis reduce shaking for straighter lines.

✅ Anti-clog nozzle structureRotary hard-edge column nozzle greatly lowers blockage frequency.

✅ Flexible dual-operation spray gunHandheld or fixed mounting modes adapt to diverse construction situations.

Application Range

✅ Municipal road marking jobs

✅ Highway traffic line construction

✅ Parking space layout marking

✅ Underground garage pavement lines

✅ Factory park traffic sign marking

✅ Residential community road line projects

FAQ

Q1: What is high-pressure airless marking machine?

✅ It uses a high-pressure pump to extrude paint directly onto pavement without compressed air, creating denser lines with stronger bonding force.

Q2: Which marking paints match this machine?

✅ Designed exclusively for ambient-temperature cold spray road marking coatings.

Q3: Can spraying width be adjusted?

✅ Adjustable from 8cm up to 45cm freely.

Q4: Does it support reflective glass bead construction?

✅ Yes, an extra bead spreader kit is available for installation.

Q5: What construction projects suit this machine?

✅ Widely used on municipal roads, highways, parking lots, industrial parks and more traffic marking sites.
