OSD-880 PUR Hot Melt Machine for 55-Gallon Drums

1.OSD-880 PUR Hot Melt Machine for 55-Gallon Drums
Large-drum PUR hot melt system · 380 V · 571 mm drum diameter

The OSD-880 is designed for 55-gallon PUR adhesive drums with a capacity of approximately 200 kg. It operates on 380 V and features 19 kW of heating power, a 571 mm drum diameter, a maximum adhesive output of 120 kg/h and a 30 cc/rev pump. As the flagship model in the PUR series, it is built for centralized adhesive supply to continuous production lines in automotive interiors, home appliances and large-scale furniture manufacturing.

A 55-gallon PUR drum measures 571 mm in diameter and holds approximately 200 kg of adhesive. This large format is commonly used on automotive and appliance assembly lines, as well as in continuous furniture production. Compared with 5-gallon drums, which may need to be changed daily, a 55-gallon drum can extend the interval between changeovers—reducing manual handling and minimizing interruptions to production. The OSD-880 is engineered around this high-capacity drum format.

The 380 V, 19 kW heating system is designed to bring a large volume of PUR adhesive from room temperature to its typical processing range of 180–200°C within a practical preheating period. The machine delivers up to 120 kg/h through one or two outlets, using a 30 cc/rev pump, with a maximum working pressure of 10 MPa.

The OSD-880 operates at temperatures from 10 to 200°C and in ambient temperatures from 10 to 60°C. Temperature control accuracy is ±1°C, using a K-type sensor. The required air pressure is 0.4–0.8 MPa. Weighing approximately 300 kg and measuring 1,500 × 900 × 1,850 mm, this cabinet-style unit may require lifting equipment for installation. Its precision-cast, CNC-machined aluminum platen features DuPont Teflon impregnation and sintering for a close fit and reliable seal against the 571 mm drum opening.

For automotive interior and appliance assembly lines, the OSD-880 helps reduce the production impact of drum changes by extending adhesive supply intervals. Its high-capacity pump and output of up to 120 kg/h can serve demanding production requirements, while the 10 MPa maximum working pressure supports stable delivery through long adhesive hoses. The low-adhesive-level alarm can alert operators when approximately 20 kg remains, allowing time to prepare a replacement drum. The machine also includes PID auto-tuning, a bilingual touchscreen, inverter protection and a high-precision pressure relief valve.

2.Key Features

3.Applications

The OSD-880 is suitable for high-volume continuous production lines using 55-gallon PUR drums, with adhesive consumption of approximately 50–120 kg/h and one or two outlets. Typical applications include:
– Automotive interior assembly
– Home appliance assembly
– Large-scale furniture production
– Centralized PUR adhesive supply from 55-gallon drums

4.Selection Guide

Choose the OSD-880 if your facility uses 55-gallon PUR drums, has adhesive consumption above approximately 50 kg/h, provides a 380 V power supply and needs to supply one or more production lines.

For lower-volume applications, consider the OSD-860 for 5-gallon drums and consumption of up to 20 kg/h. The OSD-802A is designed for 2.5 L containers, while the OSD-825A handles bulk adhesive blocks. Select the OSD-880 to match current production requirements, since its 19 kW power demand and larger installation footprint are ongoing operating considerations.
