Powder metallurgy techniques are utilised to form components and in particular titanium components in moulds. By the nature of the powder forming process, closed surfaces are created in the powder formed component, particularly when hot iso-static pressing techniques are utilised. In order to create surface texturing, and in particular entrant features, a mould lining is associated such that it reciprocates the shape of an underlying mould. The mould lining incorporates surface discontinuities such as holes, slots, spots or folds which result, once the moulded material is formed, in entrant features which can be utilised to enhance bonding through adhesives or other surface features beneficial to a component.
