OSD-106A – 5Liter Standard Piston Pump Hot Melt Glue Machine System

1.OSD-106A vs. OSD-105A: Which Pump Is Right for Your Application?

The OSD-106A and OSD-105A share the same compact platform, but their different pump designs serve different production requirements.

The OSD-105A features a gear pump, which provides continuous, relatively smooth adhesive delivery and is well suited to applications requiring consistent glue output.

The OSD-106A features a piston pump, which uses reciprocating piston movement to draw in and discharge adhesive. This design can generate higher outlet pressure, making it suitable for high-viscosity hot melt adhesives, long-distance adhesive delivery and thick-layer coating or scraping.

A piston pump produces a pulsating flow because adhesive is discharged in successive strokes. Therefore, for precision dispensing applications that require highly consistent, continuous glue flow, a gear pump may be the better option. For applications where higher pressure is the priority, the OSD-106A offers a practical alternative.

2. Key Features of the OSD-106A Piston Pump Hot Melt Glue Machine

• High-pressure piston pump: Designed for high-viscosity hot melt adhesives, extended hose runs and thick adhesive coating applications.
• 5 kg melting tank: Suitable for small-scale production and workstations with moderate adhesive consumption.
• 2,000 W heating system: Supports a rated melting capacity of up to 5 kg/h under suitable operating conditions.
• Mechanical sealing design: The pneumatic switching valve uses a mechanical sealing structure without additional sealing rings, helping simplify routine maintenance.
• Compact workstation configuration: Supports 1–2 heated adhesive hoses for flexible integration into small production setups.
• PLC touchscreen control: Uses the same operating interface as the OSD-105A, making model selection easier for users familiar with the series.
• Compact footprint: Measures 590 × 360 × 550 mm and weighs approximately 45 kg, making it suitable for space-constrained production areas.

3. Applications of the OSD-106A Hot Melt Adhesive Machine

The OSD-106A is designed for small workstations and production processes that require higher adhesive pressure or thicker adhesive application. Typical applications include:

• Woodworking and profile wrapping: Applying thicker hot melt adhesive layers during profile wrapping and surface bonding.
• Packaging industry: Adhesive application in small-scale carton and packaging operations.
• Label coating: Hot melt adhesive coating processes where the required pressure and coating method are compatible with piston pump delivery.
• High-viscosity adhesive processing: Handling suitable hot melt adhesives with viscosities approaching 15,000–20,000 CPS, subject to actual material properties and operating conditions.
• Long-distance adhesive delivery: Supplying adhesive through longer heated hoses, including configurations exceeding 5 meters, when the required pressure and flow rate remain within system limits.

For applications involving high-viscosity adhesives, long hose distances or thick adhesive layers, the piston pump design can provide additional pressure capability compared with a conventional gear pump system.

4. Mechanical Sealing Design for Easier Maintenance

The OSD-106A incorporates a mechanical sealing design in its pneumatic switching valve, eliminating the need for additional sealing rings in that assembly. The piston rod and adhesive suction cylinder also use a mechanical sealing structure designed to improve sealing durability compared with conventional rubber-ring arrangements.

These design features help reduce routine maintenance requirements and support reliable operation. The same mechanical sealing approach is used across selected models in Oushida’s piston pump hot melt glue machine series, including the OSD-812A, OSD-803A and OSD-806A.

Routine inspection should still follow the recommended maintenance schedule, with particular attention to the sealing components, adhesive inlet and pneumatic switching system.

5. How to Choose Between the OSD-106A, OSD-105A and OSD-812A

Choose the OSD-106A piston pump hot melt glue machine if:

• Your adhesive viscosity is relatively high and may approach 20,000 CPS.
• Your application requires higher adhesive outlet pressure.
• You need to deliver adhesive through longer heated hoses, such as runs exceeding 5 meters.
• Your process involves thick-layer adhesive coating or scraping.

Choose the OSD-105A gear pump hot melt glue machine if:

• Your adhesive viscosity is moderate and compatible with the gear pump.
• You prioritize smooth, continuous adhesive delivery.
• Your application requires consistent glue output, particularly in suitable automated dispensing processes.

Consider the OSD-812A if:

• The 5 kg melting tank of the OSD-106A is insufficient for your production requirements.
• You need a larger 10 kg melting tank and a 2,800 W piston pump heating configuration.

The best model depends on adhesive viscosity, required flow rate, hose length, operating temperature and the coating or dispensing method. Confirming these parameters before selection helps ensure the machine matches your production process.
