The production process of the medicine cap closing machine
In our daily life, bottle caps are commonly seen, so do you know what the production process of the medicine cap closing machine is? The following editor will tell you about it in detail.
According to the production process: it can be divided into injection molding cover and compression molding 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 plasticizes, and injects it into the mold cavity, cools it in the cavity, and demolds it. After cutting the ring and adding pads, the production of the injection molding cover is completed.
2. The production process of the compression molding cover: the suction machine sucks the mixed material into the barrel of the compression molding machine, and after the barrel is heated to a semi-molten plasticizing state, it is quantitatively extruded into the mold cavity, and the upper and lower molds are closed. , Compression molding and cooling to shape, demoulding, and then cutting rings, adding pads, and completing the production of compression molding caps.
1. The compression molding temperature is low, the shrinkage is small, and the cover size is more accurate.
2. The injection molding cover needs to heat the material to a melt flow state, and the temperature is about 250 degrees Celsius; the compression molding only needs to be heated to about 180 degrees Celsius, and the energy consumption of the injection molding cover is higher than that of the injection molding cover.
3. The compression-molding capping machine is a special machine for bottle caps, and it has a special design for the release of the bottle cap; the bottle cap injection molding machine has no special design for the bottle cap at all, so the compression-molding cap can be made into a bell mouth, and the capping rate is high. , users like to use.
4. The injection molding fills all the mold cavities at one time, and the compression molding extrudes one cap material at a time. The compression molding extrusion pressure is very small, and the pressure required for injection molding is relatively high.
5. The injection mold is large in size, and it is troublesome to replace a single cavity; each cavity of the compression molding is relatively independent and can be replaced separately.
The above is the whole content of the production process of the medicine cap closing machine brought by the editor, I hope it will be helpful to everyone.
