Bucket mould technical point

Micon Mould is professional in plastic bucket moulds, pail moulds and barrel moulds, including plastic paint pail mould, injection oil bucket mould, plastic water pail moulds.

For the capability of the bucket moulds, it could be from 500ML to 20L. For the cavity, usually we can make 1, 2 or 4 cavity. Most of the paint buckets with lid should be no leakage and have the anti-theft deisgn.

Plastic bucket mould technical points:

How to avoid the bucket mould core eccentric, which caused the bucket wall thickness not even?
1. Optimal and equal cooling effects in different area of cavity and core of the bucket moulds.

For paint bucket mould core, design the cooling channel 15mm below the molding surface.And the diameter of the paint bucket mould cooling channel should be more than 12mm, so that the water can run smoothly in the channel while taking away the heat in the core.
For paint bucket mould cavity, the cooling system design near the hot runner tip area is very important, this area is very sensitivity. Bad cooling system will directly influence the bucket's cycle time and out looking.

Of course ,some customer want to reach high speed injection with shorter cycle time, we suggest to use BeCu insert in the core top,cavity bottom and slider.

2. The lock height of the plastic bucket moulds: In general, the lock height of the plastic bucket mould is 20%-30% than the plastic bucket. Smaller barral mould is 20% and bigger pail mould should be about 30% height.

To make a high quality painting bucket mould, we have to choose suitable steel for the bucket mould.

3. The accurate machining process to the bucket mould cavity and cores.
