Plastic Bucket Mould, Pail mould
1. In order to improve the mould life and product quality, we increase the mould steel hardness through heat treatment. The steels we commonly use are H13(48-52HRC), 2316(45-50HRC) etc.To prevent mould eccentric, we use whole piece of steel to make the bucket mould. The cooling system is very important. We adopt single loop cooling way and setup even distribution water channels as much as possible.
To enhance the cooling effect, BeCu can be inserted on the core and cavity, see pictures as below:
2. Our bucket moulds use air assistance,stripper plate and centre ejector for demolding (release in two steps). In order to increase cooling performance, there also have water channels in the centre.
3. All small sliders will be nitrided to increase the hardenss.
4. It is important to keep maintenance for the bucket moulds. We should check and make sure the the water channels and air circuit unlocked. Add lubricant oil for the siliders, regularly clean the stripper plate and centre ejector.
