Grating Profile Extrusion Technology

Grating profiles are widely used in construction, industrial flooring, walkways, and drainage covers due to their strength and durability. To meet these requirements, specialized extrusion machines are designed to produce grating-type plastic profiles with consistent quality.

The grating profile extrusion machine typically consists of a twin screw extruder, a profile die, calibration and cooling units, haul-off, and a cutting system. The extrusion die is developed with reinforced flow channels to shape the raw material into grid-like structures, ensuring dimensional accuracy and mechanical stability.

During production, raw material such as PVC or reinforced plastic is melted and homogenized in the extruder. The melt then passes through the grating die, where it forms the profile structure. Cooling and calibration units help maintain shape and tolerance, while the haul-off provides steady traction to avoid deformation. Finally, the cutting unit delivers profiles of precise length, ready for installation or further processing.

Langbo Machinery applies technical expertise in die design and process optimization to enhance extrusion stability. Attention is given to material flow, temperature control, and machine synchronization, which helps ensure long-term reliability of the grating profile machine.
