How to solve the slitting problem of the plastic caps

Let Kaipu help you .

Cap slitting process is a very important part of the bottle cap manufacturing technology, it is not only related to the appearance of the product, more is directly affect the use function of the cap, if Cap slitting is abnormal, light on the outside of the bottle cap has touched upon and scratches, or on the filling line broken bridge or broken ring, moreover is Cap slitting not cutting through cap anti-theft ring failure and incurs the customer claim.

As cap production enterprises, we must keep strict control of Cap slitting process, including frequency of inspection in accordance with the relevant provisions and cutting ring tension value detection, using the standard bottle preform failure test, etc.

tension value detection, using the standard bottle preform failure test, etc.

Below,  Kaipu Intelligent Compression Molding Machine Co.,Ltd 

, is combined with pictures for you comb a incised ring process of the common defects and the method of screening, and hope to be able to help cap making companies improve defect elimination rate and improve defect source diagnostic accuracy, reduce downtime and ensure the quality of bottle caps.

Kaipu Intelligent Compression Molding Machine Co.,Ltd as the most professional manufacturer of plastic cap compression moulding production line in china,

We have the international advanced cap slitting equipment.All cap slitting equipment front end are equipped with rotary cooler with high-speed cap making machine, effective cooling cap continuous stability and ensure the cap into the ring cutting machine, cutting ring machine automatic counting device for the outlet, each box cap the number using the specified data can be automatically switch box.The cutting ring equipment produces fast and stable performance.

Kaipu plastic cap compression moulding machine’s Advantages:

Main machine Feature: 

A.Rotary muti compression molding process and advanced hydraulic system bring the highly stable and accurate production

B.Muti-cavity continuous high speed rotation, short cycle time, and high production efficiency

C.Low energy consumption in heating and cooling process.No hot runner, save energy effectively

D.No raw material wasted in spilling and hot runner circuit, Every single granule of raw material is fully used

E.Safe machine door interlock,emergency stop switch,rigid machine housing, U/L certified

D.Fully automatic in line production, no hand touching, avoid contamination

Compared with injection moulding machine and other plastic closure making machine manufacturers,Kaipu’s plastic closure compression molding machine have the following advantages:

Plastic closure Compression molding technology as a well known technology around the world in plastic closure production.

Energy saving

Less Energy Consumption,Overall energy savings per cap can be as high as 45%.

Because plastic closure compression moulding machine need lower heating temperature,which means less energy consumption in both heating and cooling.

High specific density and less shrinkage

Equal molding pressure, lower molding temperature allows the result of a higher density. Furthermore, less heating and cooling temperature gap accomplish less shrinkage of caps.

Quick color changeover without hot runners,only with the extruder.

Shorter cycle time (2 seconds) and therefore higher productivity

Due to lower extrusion temperature, caps are more quickly to be cooled down 

in mould.It makes shorter cycle time, thus capacity rises.

Easy and flexible maintenance 

Independent molds make it easier to change molds, only with hand tools but not crane.

Less material waste    

Advantages of compression cap mold:

1.High Quality 

The major cap mold material has excellent wear resistance, high

corrosion resistance and high machinability, high coating hardness

2. High Precision 

All the molds can precisely meet the dimension tolerance of cap


Kaipu has professional manufacture equipment, dedicated to

mold design and development, absolutely cope with your needs
