11.+Advanced+manufacturing+techniques

 =Here you will learn about some __advanced__ manufacturing techniques. =

The IB have split this section into 4 techniques that you must know about. In the examination you will probably be asked about the things that you may not have experienced in the studio.

These are:
 * Joining || Moulding || Casting || Forming ||

 * Permanent joining techniques. ||  Welding, for example is difficult to undo. Permanent joins are permanent, and often relate to planned obsolescence. ||
 * Adhesive. ||  A substance that unites or bonds surfaces together. Glue ||
 * Sprue. || The frame, usually made from wax, that holds the components of a model in lost wax casting. ||
 * Flash. ||  Flash or flashing is excess material attached to a molded, forged, or cast product, which must usually be removed. This is typically caused by leakage of the material between the two surfaces of a mold. ||
 * Parison. || <span style="font-family: 'Comic Sans MS',cursive;"> A hollow plastic melt, tube extruded from the die head of a blow molding machine expanded within the mold. ||

A draft angle describes the amount of taper for [|molded] or [|cast] parts perpendicular to the parting line. A draft angle describes the amount of taper for [|molded] or [|cast] parts perpendicular to the parting line. ||


 * <span style="font-family: 'Comic Sans MS',cursive;">Injection moulding. || The direct introduction of molten plastic into a die, which then cools rapidly, allowing the formed object to be released from the mould. ||
