Injection moulds
How are injection moulds created?
1. Project of the element
- a three-dimensional model of the element (3D model)
- establishing cast alignment
- the choice of materials used to create the element (taking shrinkages into consideration)
- surface finishing (surface quality, texture, structure, colour – the final finish of the product)
- tolerances of the manufactured element
- method of delivery of the element, considering installation requirements

2. Project of the injection mould
- the choice of materials for the mould
- division – outlining the elements of the mould and choosing normalised materials
- considering the type of connection with the moulding machine to be used
- considering cast shrinkages
- checking the mould elements’ collision factor
- preparing CNC programs and the technology used to create the mould

3. Mould creation
- purchase of materials
- manufacture of projected elements – CNC milling
- hardening
- grinding
- EDM processing (die-sink and wire-cut)
- surface cleaning
- threading
- matching
- socket inspection
- tightness inspection

4. First test of the mould
- mould functionality check
- manufacturing first elements
- measurement of the manufactured elements after the initial tests
- quality evaluation

5. Post-test mould adjustment
- removal of flashes
- dimensional adjustment
- surface finishing according to the project specification
