Four Designs for Injection Molds

- Apr 11, 2018-

Four design concepts had been considered in designing molds including:


1. Three-plate mould (Concept 1) having two parting line with single cavity. Not applicable due to high cost.

2. Two-plate mould (Concept 2) having one parting line with single cavity without gating system. Not applicable due to low production quantity per injection.

3. Two-plate mould (Concept 3) having one parting line with double cavities with gating and ejection system. Not applicable as ejector pins might damage the product as the product is too thin.

4. Two-plate mould (Concept 4) having one parting line with double cavities with gating system, only used sprue puller act as ejector to avoid product damage during ejection.
