Mould cost per perfect cast
Moulds are amortised over their use period. Therefore, the mould cost component per product cast is computed over the mould’s reasonable lifespan, i.e. while casting perfectly.
Over 1,000 casts (a conservative estimate), the mould component cost of a R5,000 mould is R5 per product cast.
Steel moulds do not have a comparable or predictable perfect-cast lifespan.
Labour costs, overheads, and opportunity costs
Using MCM PU moulds speeds up the production process, including curing, demoulding, mould maintenance, and storage.
Labour savings over the lifespan of a mould is achieved in numerous ways. These include:
- Rapid demoulding
- Limited maintenance
- No replacement of dented or missing parts
- Reduced management attention
Cost of quality deviations
MCM PU kerb moulds yield perfect products from every cast, with fewer rejects and less frequent mould replacement. This makes it easier to stay within the specified tolerances and to obtain a SABS certificate.
