Welcome to United Keen



 PET bottles are widely used in the beverage packing industry, mainly because PET is non-toxic and highly resistant to impact. Furthermore, PET looks crystalline and feels like glass, giving the container a better appearance than PVC, PE, or PP which have lower transparency. As a result, PET bottles and containers are playing the leading role in the container packing industry. 


Model BT-S is equipped with 2-station servo table and side-blow system.

Model BT-S is equipped with 2-station servo table and side-blow system. After injection the servo table rotates 180 degrees, a servo screw then transfers a neck plate with preforms to the side-blow station. 

Using side-blow system a bigger work space is available, and optional devices: gate trimmer and product conveyor etc can easily be mounted inside the machine. This model is good for small containers with short cycle time.



 Model BT-J has the same benefits, but is for wide-mouth jar applications, and it's a stronger machine with higher injection clamping force.
