Micon Mould is one of the plastic cap mould manufacturer in China with decades of developing experience. We have already made many kinds of cap moulds, like mineral water cap mould, 3 or 5 gallon cap mould, flip top cap mould, inner cap mould and screw cap mould etc.
For the cap mould, we want to share some technique points:
a. Adopt advanced CNC machine, EDM machine, high speed engraving machine to make sure tight tolerance;
b. Use high grade steel S136, 2316, H13 to guarantee 5million mould life and good quality;
c. Optional water cooling system for fast cycle time;
d. Stable Performance hot runner and temperature controller.
e. Self-lock in order to avoid eccentric of the mould;
f. Interchangeable core insert, it is better for future maintenance when assembly;
g. Multi-cavity for mass production;
h. All cap moulds are automatically eject;
About flip top cap mould is very important to make the flip top cap mould well to get qualified flip top caps, is required much for different kinds of flip top caps for shampoo bottle, oil bottle, tomato sauce bottle and so on.
For a good flip top cap mould, it means we could produce good flip top caps with same quality,and the flip top cap mould could run fully automatically with high production efficiency.
For a good flip top cap, when push the flip top to close, there should have sound, when we open the flip top cap to a certain location, it could open fast by itself, this required the butterfly design and also suitable raw material for the flip top cap, when the flip top cap is closed with the bottle, it must have water proof function.
After we know the requirement for a good flip top cap, we could make the flip top cap mould accordingly.
a, flip top cap mould design, the important is for injection gate location choosing, cooling system design and ejection structure design. After the mould design finished, our engineers will have a meeting to discuss about the mould movement to improve the mould structure.
b, flip top cap mould tooling, we use stainless steel material for the core and cavity,which required twice tooling. The tooling accuracy is highly required, both for the matching and butterfly function. especially for the butterfly thickness, it will decide the flip top cap closing&opening stretch.
c, flip top cap mould testing and production. The experience for machine setting is very important for this kind of mould, include the injection speed and pressure setting. Olny when we consider for all the factors, we could get a high quality flip top cap mould.
If you have new projects of cap moulds, please send us details. According to your injection machine, we can suggest the cavity number and select mould steel.
