General
Effective cooling of injection moulds is of paramount importance to achieving a short cycle time. Injection moulding process is cyclical in characteristic. Cooling time accounts for 50% to 75% of the total cycle time. Optomising cooling time for best performance is therefore very important for both quality and productivity.
Cooling time is proportional to square of wall thickness so try to ensure more or less uniform wall thickness throughout the part. Part design should also ensure that the melt flow is uniform in all directions from the gate, and melt should reach the boundaries of the part more or less at the same time.Cooling channel design (location, size and type) should ensure that melt freezes uniformly inside the mould.
We offer a wide range of cooling components.
