Common quality problems of L-shaped paper corner protectors include insufficient strength, appearance defects, and dimensional deviations:
Appearance defects
Performance
Paper corner protector There are stains and scratches on the surface, which affect the aesthetics and may also have an adverse effect on the appearance of the protected product. The color is uneven, and the color difference of the same batch of products is obvious. The edges are burred and uneven, which can easily scratch the operator or the protected items.
Cause
protector The production environment is not clean, causing dust and debris to adhere to the surface of the paper corner protector. The raw materials themselves have color differences, or the color of the paper corner protector changes due to factors such as light and temperature during the production process. The cutting equipment tool is worn and blunt, resulting in uneven cutting edges.
Solution
Paper edge corner protector Keep the production environment clean and hygienic, clean the production equipment and workshop regularly, install air purification equipment, and reduce dust and other pollutants. Strictly screen the raw materials to ensure uniform color, and control the environmental factors in the production process, such as keeping the light and temperature stable.Color paper corner protectors Replace the worn cutting tool in time, and regularly maintain and calibrate the cutting equipment to ensure cutting accuracy.
Dimensional deviation
Paper edge corner protector Performance
Paper edge corner protector The side length, length, thickness and other dimensions of the paper corner protector do not meet the design requirements, resulting in a mismatch with the corners of the protected product during use, and cannot provide good protection.
Cause
Color paper corner protectors The production equipment is not accurate enough, or the equipment fails or shifts during operation, affecting the accuracy of the size. The operator does not operate in a standardized manner during the production process, such as inaccurate paper feeding and cutting position deviation.
Solution
Color paper corner protectors Regularly maintain, calibrate and upgrade the production equipment to improve the accuracy and stability of the equipment. Strengthen the training of operators, standardize the operating procedures, and require operators to strictly follow standard operating procedures for feeding, cutting and other operations during the production process. At the same time, strengthen the monitoring of the production process to promptly discover and correct dimensional deviation problems.
