With more producers of the pails for paints introduced IML system in their production, it make the IML paints pails market getting more and more competitive. With a lower investment on the facilities will no doubt help to earn the investment back faster. Here is some recommendation of the IML solutions for 20L buckets for your reference.

Top Entry 20L IML Paint Pails Solution

As a 20L IML pails would be produced in an injection molding machine around 700T with a cycle time of 25s or longer, the robot to recommed would be SW7518DS by SWITEK Automation which is a 3 axis servo injection robot with a kick-back design, the best structure for deep cavity parts picking like an IML pails. It's the top choosed robot for an IML system of 20L paint buckets.

As a deep cavity IML container, the injection molding machine would be very important because it'll request a much larger opening stroke to ensure that the IML robot will have sufficient space to pick the buckets and insert the label. The injection molding machine to recommend here is the HD700U seriese of injection molding machine produced by HAIDA. This machine is specially designed for the production of IML pails > 20L with enlarged opening strokes.
