A forming die ( 10 ) comprises a first die part ( 12 ) and a second die part ( 14 ). The first die part ( 12 ) has a first shaped forming surface ( 16 ) and the second die part ( 14 ) has a second shaped forming surface ( 18 ). The first die ( 12 ) has a number of pillars ( 28,30,32,34 ). Two of the pillars ( 28,34 ) are arranged at a first side of the first die ( 12 ) and two of the pillars ( 30,32 ) are arranged at a second opposite side of the first die ( 12 ). The second die ( 14 ) has a number of pillars ( 44,46,48,50 ). Two of the pillars ( 44,50 ) are arranged at the first side of the second die ( 14 ) and two of the pillars ( 46,48 ) are arranged at the second opposite side of the second die ( 14 ). The pillars ( 28,30,32,34 ) on the first die ( 12 ) are locatable on the pillars ( 44,46,48,50 ) on the second die ( 14 ). The pillars ( 28,30,32,34 ) on the first die ( 12 ) and the second die ( 44,46,48,50 ) have interlocking means ( 28 B, 30 B, 32 B, 34 B, 44 B, 46 B, 48 B, 50 B) to prevent relative movement between the first die ( 12 ) and the second die ( 14 ).
