OSD-108A 220V Medium Gear Pump Hot Melt Adhesive Machine

1. High Melting Capacity Without Three-Phase Power

The OSD-108A 220V hot melt glue machine is designed for manufacturers who need higher adhesive output without upgrading to a three-phase 380V power supply. With a 10kg melting tank, 2800W heating power, and a melting capacity of 8kg/h, it delivers increased adhesive supply while maintaining a standard 220V power configuration.

For workshops without three-phase electricity, installing a 380V supply may involve additional electrical work, approval procedures, and installation costs. The OSD-108A offers a practical alternative, combining a large-capacity tank with a stable gear pump system to support multiple production stations without requiring a three-phase power upgrade.

With connections for 1–4 hot melt hoses, this machine is suitable for medium-sized production lines that need a higher adhesive supply and flexible multi-station operation.

2. 10kg Melting Tank for Fewer Adhesive Refills

The 10kg hot melt tank allows operators to load a larger quantity of adhesive at once, reducing the frequency of manual refilling and helping maintain continuous production.

The optimized heating element layout is designed to maintain a more uniform temperature throughout the tank, with a stated upper-to-lower temperature difference of within ±2°C under specified operating conditions. This helps reduce uneven melting and localized overheating, supporting consistent adhesive quality during extended operation.

A Teflon-coated surface extends along the tank walls and bottom, helping reduce adhesive buildup and making cleaning easier when changing adhesive types.

3. 6cc Gear Pump for Stable Adhesive Delivery

The OSD-108A uses a 6cc/rev gear pump designed to deliver a consistent flow of molten adhesive. Combined with the larger tank capacity and sufficient molten adhesive buffer, the system supports stable adhesive delivery for applications requiring continuous operation.

With a melting capacity of 8kg/h, the machine can operate within a relatively low-to-medium pump speed range under suitable working conditions. This can help reduce operating noise and mechanical wear compared with unnecessarily high-speed operation.

The machine supports adhesive viscosities from 1,000 to 20,000 cP, making it suitable for a range of industrial hot melt bonding and coating applications. Actual performance depends on adhesive characteristics, operating temperature, and production conditions.

4. Independent Temperature Control for 1–4 Hot Melt Hoses

The OSD-108A supports 1–4 hot melt hose connections, allowing multiple workstations or application points to operate from one adhesive supply system.

Each hose features independent temperature control to help maintain the appropriate adhesive temperature at its application point. The touchscreen interface provides color-coded temperature displays, making it easier for operators to monitor individual hose conditions and identify temperature deviations.

This configuration is particularly useful for production lines that need to supply several bonding or dispensing stations simultaneously.

5. PLC Recipe Storage and Scheduled Operation

The integrated touchscreen control system supports PLC-based process management and multiple saved application recipes. Operators can store commonly used operating parameters and retrieve them when switching between products, materials, or production tasks.

For example, furniture manufacturers can save different settings for different wood materials, while packaging operations can recall settings for different carton specifications. This helps reduce repeated manual adjustments during changeovers.

The machine also supports seven-day scheduled power-on and power-off functions, helping production teams coordinate equipment readiness with their shift schedules.

For improved operational protection, the system includes overtemperature alarms with power cutoff and inverter protection. These features provide additional safeguards during extended production, subject to the machine’s configured operating conditions.

6. Key Features of the OSD-108A

• 10kg melting tank: Increases the amount of adhesive available per refill and helps reduce operator intervention.
• 220V power supply: Provides a higher melting capacity without requiring a three-phase 380V power upgrade.
• 8kg/h melting capacity: Supports medium-volume adhesive consumption in industrial production.
• 6cc/rev gear pump: Provides controlled adhesive delivery for consistent application.
• 1–4 hot melt hose connections: Supports multiple production stations with independent hose temperature control.
• Optimized tank heating: Helps maintain more uniform adhesive temperatures throughout the tank.
• Teflon-coated tank: Helps reduce adhesive residue and simplifies cleaning during adhesive changes.
• PLC recipe storage: Makes it easier to save and recall application settings for different products.
• Seven-day scheduled operation: Helps coordinate equipment startup and shutdown with production schedules.

7. Applications of the OSD-108A Hot Melt Glue Machine

The OSD-108A is suitable for industrial applications that require reliable hot melt adhesive supply and flexible multi-station dispensing.

Typical applications include:

• Furniture manufacturing: Wood veneer bonding, panel lamination, and furniture component assembly.
• Woodworking: Wooden door lamination and other wood bonding processes.
• Carton forming: Hot melt adhesive application during carton manufacturing.
• Packaging and carton sealing: Adhesive dispensing for packaging assembly and sealing operations.
• Nonwoven manufacturing: Adhesive application and nonwoven material lamination.
• Automated production lines: Integration with compatible automatic dispensing and bonding equipment.

The machine is particularly suitable for medium-sized production lines operating on 220V power, with adhesive consumption of approximately 5–10kg/h and 2–4 application stations, provided the actual adhesive demand remains within the machine’s rated capacity.

8. How to Choose the Right Hot Melt Glue Machine

Choose the OSD-108A if your workshop uses 220V power, requires a melting capacity of around 8kg/h, and needs to supply multiple application stations without upgrading to three-phase electricity.

Consider the OSD-820B or OSD-830A if your facility already has a suitable 380V three-phase supply and your production line requires a substantially higher adhesive melting capacity, such as 20kg/h or more. Confirm the specifications of the selected model against your actual adhesive consumption.

Consider the OSD-812A piston pump model if your application requires different pressure characteristics, such as demanding high-pressure dispensing or particular high-viscosity adhesive applications. The appropriate pump should be selected according to adhesive viscosity, dispensing pressure, and application requirements.

The OSD-108A provides a practical balance of tank capacity, melting output, and power requirements for manufacturers seeking to increase hot melt adhesive supply without a major electrical infrastructure upgrade.
