First: Measurement of the overall height size of plastic bottles The overall height size of the plastic bottle refers to the vertical distance of the bottle to the bottom of the bottle. The method of measurement is to place the plastic bottle on the horizontal plane, contact one end of the cursor caliper to the highest point position of the bottle mouth, then rotate the bottle 360 Degree, read the maximum value and minimum, and control the data with the design drawing size to see if it is consistent. If the specification is 40-60 ml of a plastic bottle, its height size should be controlled within ± 0.5 mm. Second: Measurement of the diameter of the outer outer portion of the plastic bottle For this part of the measurement, the method is to span the measurement tool scale across the center of the bottle mouth, avoid the position of the bottle body, the spindle is close to the thread of the mouth, rotate the circular bottle mouth 360 degrees, The maximum value and the minimum were measured, compared with the bottle design drawings, and the outer diameter error should be controlled within ± 0.1 mm.
Three: Measurement of the shape of the shape of the plastic bottle For this part of the measurement, the method is to contact the maximum outer diameter measurement position of the bottle with the measurement surface of the cursor caliper, and the laminated caliper is rotated, and the plastic bottle is rotated 360 degrees, and read the maximum value and the minimum. The error should be controlled in the range of 0.L mm. Four: Measurement of wall thickness dimensions of various parts of plastic bottles For a pharmaceutical plastic bottle of a circular rotary body, the measurement area of the symmetrical portion is cut with a tool, so that the measuring tool can enter the detection point of the various parts of the bottle body, the thickness of the plastic bottle, shoulder thickness, The thickness of the body, the surface of the bottom thickness of the bottle performs strict measurement, and reads the maximum value and the minimum, controlled the design drawing data to test whether the tolerance of the thickness dimension of the plastic bottle is within the standard range.
