Stackable Plastic Tray Mould

The design points of the tray mould

1. Ejector angle analysis for product

Tray's main thickness is 2.75mm, some parts with rib are 3mm, this thickness is perfect for customer demands of lightweight.

In the cavity side, the hole depth of nine tray legs is 152mm, sidewall angle is 0.3 degrees. This angle is ok for the deep cavity products.

The depth of the rectangle hole in the cavity side is 40mm, sidewall angle is 1 degree. It's suitable for mold ejectors.

The depth of the square hole in the cavity side is 40mm, the sidewall angle is 0.5 degrees. The ejector angle is a little small, need to make good polish to help the ejector.

2. Mold structure analysis

The cylinder outside structure is easy for assembling, but the mould size will be big. The inside cylinder machining is a little complex but could keep spare parts of the cylinder very well.

3. Mold-flow analysis

According to the customer's material physical property table, use mold-flow analysis to decide the position of the runner gate.
