Designing Components The following should be borne in mind at the design stage: • Be aware of where the split line will fall • Think about removing the part from the mould when it is hot and soft • Rubber parts do not generally need taper • Re-entrant shapes are practical in rubber • Core out thick sections which would extend cure times • Geometric shapes make for economic tools • Combine features - such as seals, springs, logos and tolerance take-up - from other parts.
