[appearance] take the right amount of this product, in the natural light bright place, face up to visual inspection, should be clean, no residual lubricant, burr, damage.

[mechanical properties of aluminum parts] The tensile strength of the material shall be 130-180n /mm and the elongation shall not be less than 2%.

[flange] take an appropriate amount of this product and measure with vernier caliper, accurate to 0.1mm, flange should not be more than 3%.

[opening force] Opening force of type B (two Bridges) and type C (three Bridges) aluminum cover: 25N < type B tear piece < 60N, 46N < type C tear piece < 76N; Tearing force of type D (tearing type) aluminum cover: 30N < bridge breaking force < 50N; 5N < total open force < 25N.

[thickness] the thickness shall be determined by the buyer and the seller through negotiation within the given range, and the thickness and tolerance shall not exceed ±0.022mm.

[sterilization resistance] take an appropriate amount of this product, rinse it with water and bake it in an oven at 180℃ for 1 hour. The surface should remain unchanged, and the surface layer should be free from uplift and detachment.

[compatibility] after baking at 180℃ for 1 hour, cover the appropriate amount of this product on the bottle containing the nominal capacity of water (add the rubber plug), and use the sealing device to seal the product. It should be properly matched, and no fracture or abnormal deformation is allowed.

[coating firmness] take an appropriate amount of this product (suitable for aluminum cover with coating on the outer surface), bake for 1 hour at 180℃, wipe the surface with absorbent cotton soaked with 80% (V/V) ethanol solution for 30 seconds, then wipe the surface with absorbent cotton soaked with 70% (V/V) isopropanol solution for 30 seconds, the coating should not have any wear. glass bottle
