How is plastic bucket mold made?

Bucket mold is one of our most important plastic injection mold, our bucket mold includes thin wall bucket mold, food bucket mold, pail mold, cylinder bucket mold, square shape bucket mold,cuboid bucket mold, industrial use bucket and pail mold, water bucket mold, industrial paint bucket mold, fishing bucket mold, packing bucket mold, dustbin bucket mold,cement pail mold, plastic barrel mold and other bucket molds.

Firstly, Mold Design and Structure

A high-quality mold structure is a premise for a qualified mold before manufacturing.We attach great importance to analyze mold structure, including demolding draft angle, the epitome of product surface, gating system design, exhaust design, cooling system design etc.The main problems that may easily occur will through trial and error during the mold structure design.

Second, the Mold Steel

In order to improve the mold life and product quality, we increase the mold steel hardness through heat treatment. The steels we commonly use are H13(48-52HRC), 2316(45-50HRC) etc.to prevent mold eccentric, we use whole piece of steel to make the bucket. 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.

Our bucket molds 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.

All small sliders will be nitrided to increase the hardenss.

It is important to keep maintenance for the 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.

Third, the Mold Cooling system

Cooling system design is a relatively cumbersome work, namely to consider the uniformity of the cooling and the cooling effect, also the impact brings to the overall mold structure, determining the exact location and size of the cooling system; and cooling for key positions such as moving plate or the inserts, side sliders as well as side cores;standard cooling element design and the selection of the cooling standard components. Heya plastic mould analyzes all series of factors when begin to start the mold design. The mold has recycled water to flow in every part of it which reduces the cooling time, improves the production efficiency and greatly reduces products costs.
