Everyone will find that we need to open the bottle cap when we drink. Is there a point underneath that melts together? This is a one-time opening and there is no way to fuse together. This part is the breaking point of the bottle cap. How to make the breaking point of the bottle cap?
There are three solutions to the breaking point of the bottle cap:
1: The mold is made directly. When making the mold, divide the cavity on both sides, and reserve the breaking point on the mold! Part of the mineral water cover is made in this way.
2: Cut after the product is made. Cut the product with a notch machine after injection molding! The blade of the notching machine is notched! Part of the mineral water is cut.
3: Ultrasonic welding machine welding. The product is made in two parts, and then the welding points are welded by an ultrasonic welding machine. The caps of liquor bottles are basically welded by the welding machine to break points!
