Why continuous cap compression molding is the best choice?
For example, in a 128-cavity injection mould you have 128 heaters at the nozzle and at least 32 heaters in dispension pipe. In the hot runner we can find burnt plastic and burnt grease.
No hot runner, it means LESS RESIDENCE TIME.
No hot runner, it means LESS COLOR CHANGE TIME.
No hot runner, it means NO DOWNTIME for CLEANING.
Cap injection molding
Cap compression molding
The pressure is stable in the process of the compression molding, unlike injection molding which results in pressure loss through hot runner and injection point.
Although the compression molding temperature can be set to the same as that of injection molding, it does not need such high temperature to overheat the raw material, because the compression molding does not need to completely heat the material to melt flow state.
The higher the temperature, the greater the chance of surface roughness.
Obvious superiorities of continuous cap compression molding:
1) Greater repeatibility of the closures > Single mold with the same thermal equilibrium
2)Save in electrical consumption. > Lower extrusion temperature
Lower cooling consumption
Lower moulding pressure needed
3)Shorter cycle time > Shorter cooling time required
4)Easier maintenance > Seperated mold
No cranes needed
Quick replacement of mold cavity
5)Easier quality inspection > Closures oriented and spaced on the outlet channel
Camera system on-line video inspection
Popular cap models in bottled water&beverage application:
In terms of bottle neck finishes, it includes 3025,2925,1881,1810,38mm, 2622etc.
For still water,3025 cap compression molding is normally used in the market. 2925 is the lightweight based on 3025 cap molding.

Does injection gate affect cap’s function?
Generally speaking,in cap printing, such as CSD caps, normally need printing logo and pattern on the top.The small point would affect printing,the weak adhesive function always lead to incomplete and flaky pattern. Caps made by cap compression molding machine, cap top is smooth and suitable for various of patterns. Injection gate is easy to get jam in production, there is some unmelted matter(like iron wire and nylon string etc.) exist in injection gate and cause jam, then results in thin top and seal plug starving, thus, lead to weak seal function after filling.This issue always causes product recall in the future,which is a deadly attack to water/beverage brand, plastic caps manufacturers are unable to undertake such big loss and compensation. In continuous compression moulding, this troublesome doesn’t exist.
