How to solve the problem of unstable product size and uneven wall thickness during the production process of SPC flooring line?

Reason analysis: The current fluctuation of the SPC floor line host is large, the lubrication inside and outside the formula is unreasonable, the extrusion is unstable, the feeding speed is unstable, the screw barrel is severely worn, and the fit gap is incorrect.

Solution: Find the specific reason for the high current fluctuation of the SPC floor line host, improve the internal and external lubrication ratio appropriately, and correct the feeding screw. Due to the SPC filling ratio reaching 1:3.2-3.5, the wear of the screw and screw barrel is relatively large, and regular replacement of the screw is necessary.
