Semi-automatic PU Glue Injection Machine

The Semi-Automatic PU Dispensing Machine
This advanced system is engineered specifically for efficient and precise dispensing of polyurethane (PU) adhesives and sealants. It delivers an effective balance between automation and manual operation, providing an optimal solution for medium-to-low volume production runs or complex processes requiring accurate adhesive control, enhanced productivity, and cost management.

Mechanical sealant head, anti-drip glue, anti-reverse glue

10 inch touch screen, PLC, stepless speed regulating motor, metering pump,

A1, A2, B stainless steel storage tank, cleaning tank, dust- bin

The equipment is suitable for: commercial vehicles, buses, construction machinery, air compressors and other air filter PU glue process.

Touch screen operation, large memory, can store 90 formula models.

The equipment is equipped with automatic cleaning, automatic exhaust gas, automatic color conversion, overpressure alarm.

When working, the formula model is changed, and the turntable is automatically ad- justed to the glue spitting position.

After the formula is set, the rotating disc can automatically adjust the speed and moving distance according to the different filter type.

The stepless speed regulating motor and precision metering pump can precisely adjust the amount of glue.

Heating system adopts tropical heating.

High pressure teflon pipe is used for circulaton pipeline.

B material vacuum feeding, A1A2 using diaphragm pump feeding.

Our system integrates high-accuracy gear pumps or screw pumps with advanced process controls, maintaining strict Component A/B ratio stability for polyurethane adhesives. This foundation-level precision guarantees consistent end-product quality.

Operators freely adjust bead profiles and flow rates to match specific application requirements across diverse products and processes. The resulting control significantly reduces common defects such as glue starvation or excessive spillage.
