In principle, the cost of an injection mould starts at around €5,000 and can go up to several hundred thousand euros. Approximately 20% of the cost price of an injection mould consists of purchasing, and the man-hours required for the various processing steps such as engineering and drawing, milling, turning, electrical discharge machining (EDM), drilling, grinding, polishing and assembly work. The costs for an injection mould are primarily determined by the complexity of a product (3D geometry), the projected production number per year, the required lifespan, the number of mould cavities (multiplicity), the method of injection (conventional or by hot-runner) and the possible need for slides (presence of undercuts).
