Selecting the correct industrial PUR adhesive machine requires comparing the production line requirements with the equipment specifications.
The SP-PUR55 provides a maximum glue supply range of 60–100kg/h. Buyers should compare this range with actual adhesive consumption rather than relying only on the nominal barrel capacity.
The required supply rate may vary according to the application method, bonding width, adhesive viscosity, temperature, and production speed.
The machine has an operating temperature range from normal temperature to 250°C and provides temperature control precision of ±1°C.
Before purchase, confirm the recommended melting and application temperature of the PUR adhesive. The machine setting should follow the adhesive manufacturer’s technical specifications.
The SP-PUR55 uses a 380V 3P+N power supply and supports an applicable air pressure range of 0.5–0.8MPa.
The customer’s factory should confirm that the electrical system, air supply, and installation environment meet these requirements.
The machine supports one or four output lines. Buyers should select the configuration according to the number of adhesive application points and the layout of the production line.
The output line configuration should be confirmed before ordering because it affects hose arrangement, applicator connection, and installation planning.
The installation size is approximately 1450 × 900 × 1650mm, and the machine weight is approximately 460kg.
The installation area should provide sufficient space for barrel loading, operation, maintenance, and safe access around the machine.

Operating a 200KG PUR glue machine requires consistent procedures for heating, dispensing, cleaning, and maintenance. Correct operation helps protect the adhesive quality and reduce the risk of carbonization or pipeline clogging.
Before starting the machine, operators should confirm the air pressure, power supply, barrel installation, and condition of the melting plate. The melting plate should be cleaned to remove residual adhesive before production.
Follow this standard operating process for your 200KG PUR glue machine:
Confirm that the 380V power supply, 0.5–0.8MPa air pressure, and 200kg adhesive barrel are properly connected and installed.
Set the temperature according to the PUR adhesive specifications. Allow the adhesive to melt fully, then test the glue output at the lowest flow rate.
Adjust the glue supply according to the application requirement, monitor the temperature and pressure, and purge the pipeline with cleaning oil after production.
PUR adhesive may cure inside the system if it is exposed to unsuitable conditions or left in the pipeline for an extended period. For this reason, operators should follow an appropriate cleaning schedule and avoid overheating the adhesive.
During operation, the machine should be checked for glue shortage, abnormal pressure, temperature fluctuation, and output instability. The melting plate and pipeline should be maintained according to the machine instructions and adhesive supplier’s recommendations.
Follow a clear evaluation process when selecting a 200KG PUR adhesive injection machine.
First, calculate the actual adhesive supply requirement in kg/h. The SP-PUR55 has a maximum glue supply range of 60–100kg/h, but the correct working output depends on the adhesive and production process.
