The explain regarding the pail mould core eccesntric causing the bucket wall thickness not even and the bucket out of center.


1. The machining process is meaning which kind of machining should we select and what we should take care when we make the machining to the bucket mould core and cavity.


2. If the cooling is not equal in the different area of the bucket mould core and cavity, this will cause the following difference of the melted material, the more hot area flowance will be bigger and the colder area the flowance will be smaller. then the hot area's bucket wall thickness will be thicker. The temperature difference normally caused at least 0.05mm.


3. Normally, the bucket mould the interlock height should be 20 to 30% of the plastic bucket 's height, for example the smaller bucket should be 20%, the bigger bucket mould should be around 30% height.

For how to make the ejection smoothly, automaticly and safely?


this is the topic which we should talke, as because paint bucket is different as all the other kinds of bucket, there is one undercut on the edge of the bucket mouth, and this undercut (rib) need to be strippered before it drop down. 


If there is any other strength ribs on the edge of the bucket, then we need to use angle lifts to make the paint bucket mould ejection. 


The beryllium copper on the core top and cavity neck lead to a very good cooling for the mould,and our latest  deisgn for the core and cavity would prelong the mold life:the original paint bucket mould alignment and lock system is a round one,while we design an octagon step to have a better alignment and lock for the core and cavity,also which change would prelong the paint bucket mould life.


JTP Mould made more then 1000 sets of paint bucket during these 10 years, we have very strong technical knowledge and experience on paint bucket mould design and manfuacturing.
