Handle the quality inspection report of plastic stationery boxes.
1. Overview. Plastic stationery box is one of the commonly used school supplies for students, and its quality is directly related to the safety and comfort of students. In order to ensure the quality of plastic stationery boxes, including pattern requirements, appearance requirements, heat sealing, bonding, magnetism, folding resistance, drop strength, temperature resistance, pressure resistance and safety requirements, etc.
Second, the pattern requirements.
The pattern of the plastic stationery box is required to be clear, beautiful and easy to identify. Inspect whether the pattern on the stationery box meets the design requirements, and whether the color, line and details of the pattern are clearly visible.
3. Appearance requirements.
The appearance of the plastic stationery box is required to be neat and smooth, without obvious flaws and defects. Detect whether the surface of the stationery box is flat, whether there are scratches, unevenness or deformation.
Fourth, heat sealing requirements.
The heat sealing of plastic stationery boxes is required to be firm and seamless. Inspect the heat-sealed part of the stationery box by looking and touching to ensure that there are no obvious gaps and loosening.
5. Bonding requirements.
The bonding of plastic stationery boxes is required to be stable and non-shedding. Check whether the adhesive part of the stationery box is firm, and whether there is any glue opening or falling off.
6. Magnetic requirements.
The magnetic requirements of the plastic stationery box are moderately strong and weak, which is convenient for students to use. The magnetic strength of the stationery box is measured by a magnetometer to ensure that it meets the requirements of the standard.
7. Folding requirements.
The folding resistance of plastic stationery boxes is high and it is not easy to break. The folding resistance of the stationery box is tested by folding and twisting multiple times to ensure that it will not easily break or deform during use.
8. Drop strength requirements.
The drop strength of the plastic stationery box is required to be high, and it is not easy to break. The drop strength of the stationery box is detected by simulating actual use scenarios to ensure that it will not be easily broken or damaged during use.
9. Temperature resistance requirements.
Plastic stationery boxes have high temperature resistance requirements and are not easy to be deformed by heat. The temperature resistance of the stationery box is tested by high temperature test to ensure that it will not be deformed or cracked due to temperature changes during use.
10. Pressure resistance requirements.
Plastic stationery boxes have high pressure resistance requirements and are not easy to be flattened or deformed. The pressure resistance of the stationery box is tested by simulating actual use scenarios to ensure that it will not be easily flattened or deformed during use.
Ten. 1. Safety requirements.
Plastic stationery boxes have high safety requirements, non-toxic and harmless. Check whether the material of the stationery box meets the safety standards and whether it contains toxic substances. At the same time, it also detects whether the corners of the stationery box are sharp and whether there are potential safety hazards. In all these respects, it is ensured that the plastic stationery boxes tested comply with the relevant standards and requirements.
