In the process of making and processing anti-uv pet bottle packaging, the appearance detection of anti-uv pet bottle packaging is very important. How to detect the appearance of anti-uv pet bottle packaging?

anti-uv pet bottle packaging outer diameter measurement: The specific measurement method is to cross the center of the bottle mouth with the measuring tool, avoid the position of the bottle body mold line, and rotate the round bottle mouth 360 degrees at the thread of the main shaft tight mouth, measure the maximum and minimum value, and compare with the bottle design drawing, and the outer diameter error should be controlled within the range of positive or negative O.10mm.

anti-uv pet bottle packaging diameter measurement: The measuring method is to use the measuring surface of the vernier caliper to contact the measuring place of the maximum outer diameter of the bottle body, tighten the vernier caliper, and then rotate the anti-uv pet bottle packaging body 360 degrees, and record the maximum and minimum sizes, and the error should be controlled within 0.1Omm.

anti-uv pet bottle packaging overall height size measurement: The so-called overall height size of the anti-uv pet bottle packaging refers to the vertical distance from the mouth of the anti-uv pet bottle packaging to the bottom of the bottle. The test method is to place the anti-uv pet bottle packaging on the horizontal surface, touch the end of the vernier caliper to the highest point of the bottle mouth, and then rotate the bottle body 360 degrees, read out the maximum and minimum size value, and check whether the size is consistent with the design drawing. For example, the size error of 40-60mm bottle height should be controlled within the range of 0.5mm.

Measurement of wall thickness in various parts of ET bean bottle: For the anti-uv pet bottle packaging of the round rotary body, the measuring area of the symmetrical part is cut with a tool, so that the measuring tool can enter the detection point of each part of the bottle body. At this time, the thickness of the anti-uv pet bottle packaging mouth, the thickness of the shoulder, the thickness of the body, and the thickness of the bottom of the bottle can be strictly measured, and the maximum and minimum values can be recorded, and the dimensional tolerance can be checked against the uncalculated drawings of the bottle products.

The inspection of the appearance quality of anti-uv pet bottle packaging is based on the different defects in each part of the anti-uv pet bottle packaging, and different appearance defect standards are formulated. The appearance quality of the anti-uv pet bottle packaging is usually marked with the minimum allowable limit or a standard sample is made. It is best to seal one of each defect in the standard sample for comparison and verification.

The appearance of anti-uv pet bottle packaging is very important. Due to the different precision of the production of anti-uv pet bottle packaging, the selection of raw materials and process parameters, the dimensional accuracy of the appearance will be different. The appearance detection of anti-uv pet bottle packaging mainly includes the overall shape, surface tone, gloss, appearance quality and other visual quality characteristics of the anti-uv pet bottle packaging.
