Progressive Heating & Precise Temperature Control
The machine features progressive heating melting with ±1°C temperature control precision, supported by Pt100/K-type temperature sensors. This ensures consistent PUR hot melt glue performance, preventing carbonization even under continuous operation, ideal for high-demand PUR hot melt adhesive bonding processes.
High-Capacity, Stable Glue Output
Designed for 200kg (55-gallon) barrels with a maximum glue supply of 60–100kg/h, it delivers reliable flow for large-scale production. The speed control AC motor gear pump ensures stepless adjustment, meeting the precise dosing needs of woodworking lamination, textile composite, and automotive interior applications.
Durable, Low-Maintenance Build & Safety Design
Equipped with a Teflon protective layer to reduce clogging and extend service life, plus an IP54 protection rating for enhanced durability in industrial environments. With a total weight of 460kg and a 9MPa maximum working pressure, it ensures stable performance under harsh production conditions.
Flexible Operation & Smart Protection Features
Supporting 1 to 4 output lines, the system adapts to diverse production line configurations. It includes a glue shortage alarm, humanized main motor protection functions, and 0.5–0.8Mpa air pressure compatibility, making it a versatile and reliable industrial PUR hot melt glue machine for multi-scenario bonding needs.

Woodworking & Furniture Manufacturing
It excels in wood coating fitting and edge banding, delivering strong, invisible PUR bonds for furniture panels, door frames, and decorative moldings. The fast-curing adhesive ensures durable, moisture-resistant joints ideal for high-volume production lines.
Textile & Lamination Industry
Used for textiles lamination, it bonds fabrics with foams, films, or non-wovens in a continuous, controlled manner. The machine’s precise glue output ensures even coverage for automotive upholstery, hygiene products, and apparel components.
Packaging & Stationery
Perfect for PET transparent boxes and bookbinding, it provides clear, strong seals for rigid packaging and permanent binding for books and notebooks. The air-isolated melting prevents glue discoloration, maintaining product aesthetics.
Automotive Interior Assembly
It reliably bonds auto inner decoration pieces like door panels, instrument panels, and headliners. PUR adhesives offer superior resistance to temperature fluctuations, vibration, and common automotive chemicals.
Household Appliance Assembly
Applied in assembling components of home appliances, it creates robust bonds for plastic, metal, and composite parts. The machine’s consistent output ensures reliable performance in demanding, high-temperature environments.
Step-by-Step Operation Guide for SP-PUR55 PUR Hot Melt Glue Machine
Pre-Use Check
Confirm air pressure (0.5–0.8 MPa), power supply (380V), and glue barrel installation are secure. Clean the melting plate to remove residual glue.
Start-Up & Heating
Power on the machine, set the temperature to 120–160℃ (per your glue specs). Wait for full melting, then test glue output with the lowest flow rate.
Production Operation
Adjust glue flow (60–100 kg/h) to match your process. Monitor the temperature and pressure gauge during continuous use.
Shut-Down & Maintenance
Stop glue output, purge the pipeline with cleaning oil, then power off. Wipe the machine surface and check for carbonization weekly.
Q: What’s the maximum glue output rate of this machine?
A: The SP-PUR55 has a glue supply range of 60–100 kg/h, adjustable via the speed control motor. This fits most medium to high-volume production lines.
Q: What temperature should I set for the PUR glue?
A: The operating temperature range is up to 250℃, but we recommend 120–160℃ for most PUR adhesives. Always follow your glue supplier’s specs.
Q: How do I prevent glue carbonization and clogging?
A: The machine uses progressive heating and a Teflon coating. To avoid clogging, purge the system with cleaning oil after each use and avoid overheating the glue.
Q: Can this machine connect to multiple glue dispensing guns?
A: Yes, it supports 1 or 4 output lines, allowing you to connect multiple guns for multi-point gluing applications.
Q: What maintenance does this machine require?
A: Clean the melting plate weekly, check air pressure (0.5–0.8 MPa) daily, and replace filters regularly. The low-maintenance design ensures long service life.
