Pail mould technical points explainations.
A. the explain regarding the pail mould core eccesntric causing the pail wall thickness not even and the pail out of center.
1. if the cooling is not equal in the different area of the pail 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 pail wall thickness will be thicker. The temperature difference normally caused at least 0.05mm...
2.normally, the pail mould the interlock height should be 20 to 30% of the plastic pail's height, for example the smaller pail should be 20%, the bigger pail mould should be around 30% height.
3.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 pail mould core and cavity.
Paint bucket mould and plastic moulded paint bucket.
The technical point for the paint bucket is the paint bucket wall essesntric and ejection system. For the eccessntric, we have talked on the page: www.cnmould.com/pail-mould.html
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.
Sino Mould made more then 1000 sets of paint bucket during these 11 years, we have very strong technical knowledge and experience on paint bucket mould design and manfuacturing.
