In our daily life, bottle caps are usually visible, so do you know what is the production process of the medicine cap closing machine? The following editor will give you a specific talk.

According to the production process: it can be divided into injection cover and compression cover.

First, the production process of the injection molding cover: the suction machine sucks the mixed material into the barrel of the injection molding machine, heats it in the barrel to melt and plasticize it, and then injects it into the mold cavity, and cools and sets in the cavity. The mold is then cut through the ring and padded to complete the injection molding cover.

Second, the production process of the compression molding cover: the suction machine sucks the mixed material into the barrel of the compression molding machine, heats it in the barrel to the semi-melting plasticization state, and extrudes it quantitatively into the mold cavity, up and down The mold is closed, compression molded, cooled and shaped, demolded, and then the ring is cut and cushioned to complete the compression molded cover.

1. The compression molding temperature is low, the shrinkage is small, and the cap making scale is more accurate.

2. The injection molding cover needs to heat the material to the melt flow state at a temperature of about 250°C; compression molding only needs to be heated to about 180°C, and the energy consumption of the injection molding cover is higher than that of the pressure injection cover.

3. The compression molding cap making machine is a special machine for bottle caps, which has a special plan for the demoulding of bottle caps; the bottle cap injection molding machine has no special plan for bottle caps, so the compression molded cap can be made into a bell mouth and hung. Cover rate is high, users like to use.

4. Fill all the mold cavities at one time by injection molding, and extrude one cap material at a time by compression molding. Compression molding extrusion pressure is very small, while injection molding pressure is relatively high.

5. The injection mold is bulky, and it is troublesome to replace a single cavity; each cavity of compression molding is relatively independent and can be replaced independently.

The above is the entire content about the production process of the medicine cover closing machine brought by the editor, I hope it will be helpful to everyone.
