The bottle cap is pressed by a manual picking and pressing machine. Then the bottle cap and the bottle body are fitted and ground to form a surface. In manual blowing, the small size below 250m is generally used for one-shot blowing, and the large size above 250mI is first blown for small bubbles, and then the second time for blowing. Under normal circumstances, the difficulty of F large-mouth blowing is small and high, and the qualified rate of finished products is small and low. It is suitable for various industrial and mining enterprises and laboratories of universities and colleges for storing various chemicals and reagent solutions.
