Description
Technical Field
The invention belongs to the field of bottle cap production, and relates to high-speed molding equipment and process for a conjoined bottle cap.
Background
The conjoined bottle cap is a common packaging bottle cap, and is mainly used for packaging foods such as soy sauce and vegetable oil and daily necessities. The one-piece bottle cap is generally composed of two or more parts which are connected with each other through a certain structural design so as to realize good sealing performance and a convenient opening mode.
At present, the processing methods of the conjoined bottle cap mainly comprise injection molding and compression molding. Injection molding is a common plastic processing method by placing plastic raw materials into a mold, then applying pressure and temperature to melt and fill the corners of the mold, and finally forming a bottle cap having a desired shape and size. However, the injection molding process has some problems in producing the one-piece bottle cap. Firstly, injection molding speed is slower, and production efficiency is lower. Secondly, defects such as flash easily appear in the injection molding process, and the quality and the attractiveness of the product are affected.
Thus, compression molding of the closure is a better production process. Bottle cap compression molding differs from injection molding in that it uses simple molds and presses to compress plastic feedstock into the desired shape and size by the application of pressure and temperature. Bottle cap compression molding has many advantages such as low equipment cost, high production efficiency, stable product quality, etc. However, the integral bottle cap has a complex structure and can only be produced by using an injection molding process at present. This is because the individual parts of the one-piece closure need to be interconnected by a certain structural design which is difficult to achieve during compression moulding.
