1. Design for Manufacture
Higher product design

2. What makes it a success? The product function as intended
The product looks good and is considered desirable
The product is cost effective
The product is able to be manufactured
Design team approach
Aware of demands of manufacturing and costs
Efficient cost effective decisions can be made and changes can be discussed.

3. Standardisation Cuts costs Better if applied to more than one product
Example:
A car. Some parts can be used across a range of cars and used in partnership with other manufacturers. VW, Audi, Seat and skoda all share parts in their models.

4. Modern Manufacturing Methods
Vital to know how things are made in industry to be a success.
Now a great flexibility and choice in methods for designers.
Curves and difficult shapes easier to produce
Textures and detail are now common practice
Mould making has improved
Restrictions are still in place though!
Location of injection and ejection points cause small blemishes and are usually designed to be hidden.
Examine and analyse how products that use similar manufacturing processes are made.

5. Modern Manufacturing Methods(contd)
Design features to plastic castings that may cause restrictions:
Split Lines: occur naturally when two parts of outside casing join together often leaving a small groove. Usually found at widest part of product.
Break Lines: lines or grooves on surface parts of product. Used to divide up featureless areas, add details or features to one part of products. Used to cover up distortions that may occur as a result from manufacturing.
Tapered Sides: Necessary part to any component that are injection moulded. Allows it to be easily removed from moulds. Tapers are as little as 1◦.
Webs: Usually internal features to add strength or support parts. They can be used on the outside and a feature.
Surface Textures: Used on mass produced items. Produced through process called spark erosion – method to texture inside surfaces of moulds.
