Finished tiles show obvious height difference on both sides and inconsistent size at two ends, known as "different head and tail size", resulting in high rejection rate in mass production.
Main causes: slightly deformed machine frame, excessive pressing force on one side forming roller, and uneven stress during inclined sheet feeding.
Standard solutions: Precisely calibrate the level and squareness of machine frame; balance the pressing force of left and right forming rollers for even stress; standardize feeding operation to ensure straight parallel feeding and effectively improve asymmetric height and size deviation.
