1.Schematic for methodical and planned designing of injection molds:
Good design practice:
- Use the simplest possible design.
2. Make full use of standard components.
3. Use tried and tested designs in preference to new, unknown designs.
4. Critically examine any existing samples that have been provided for gate positions,
ejector positions, sinks, distortion, etc.
5. Check with the toolmaker that they have the equipment necessary for the design.
6. Attend sampling trials for essential feedback information and to advise the sampling
technician on the tool function.
Golden Rules :
1. Never start a mould design without all the necessary information.
2. If an established design works well, don’t embark on a totally new design if you can
base your design on the established one.
3. The simpler the design the more reliable and efficient it will be.
4. Always sketch two or three alternative approaches to the design before committing
yourself to the first one you think of.
5. Draw a sufficient number of views so that the design can be understood fully.
