3.3.11 Specialist techniques and processes GapFill

Specialist manufacturing techniques and processes should be used with accuracy when manufacturing products. Manufacturing techniques that involve the assembly and joining of parts are known as  deformingfabricationassemblingwasting, and there are specific techniques for each material. Whether cutting fabrics, metals, paper or timber, cutting is a  wastingfabricatingcostlyforming process, and if it is not done accurately, parts will not join together as intended. Surface treatments and finishes are applied to materials for several reasons including  increasing the functional performance ofhiding gaps incovering up cheap materials used forincreasing the price of the product and aesthetic purposes. When getting a material ready for the application of a surface treatment, careful preparation is essential otherwise the surface could end up  looking greatcolourfulattractiveblemished. Appropriate use of  measurementcheckingPPErisk should also be followed when applying any hazardous surface finishes. One of the biggest factors to cause degradation in the surface colour of many materials is the damage caused by  HASLUVHIPSCD from the sun. One of the other major causes of surface degradation and deterioration of a whole range of materials is  hydrogenstainnitrogenmoisture in the air and humidity.
