Meaning
Financial allocation of initial mould design and manufacturing costs across total produced part volume determines the per-unit capital cost contribution. Calculating tooling amortization requires dividing total mold engineering, machining, and sampling expenses by expected production volumes over the tool’s operating lifecycle. High production volumes lower per-part tooling costs, justifying expensive multi-cavity hardened steel moulds over single-cavity prototype tooling.
Premature tool failure or premature product line termination leaves unamortized capital expenses that increase overall piece prices.
Cost Allocation
Machine cavity count directly impacts initial tooling expenditure and per-unit capital allocation rates. Accounting for tooling amortization involves adjusting piece part prices based on verified production volume milestones. High-cavity moulds carry higher upfront tooling costs but achieve rapid capital recovery across mass production runs.
Maintenance and repair costs are accounted for separately as operational expenses rather than capital amortization.
Lifecycle Economics
Steel selection determines maximum mold life and total amortizable production volume capacity. Aluminium prototype tooling offers low initial cost but wears quickly, limiting cost spread over small production runs. Hardened H13 steel moulds sustain millions of cycles, spreading capital costs down to fractions of a cent per part.
Financial Risk
Inaccurate sales forecasts risk under-recovering tooling investment before product obsolescence occurs. Contract manufacturing agreements often include minimum production volume guarantees to secure tooling capital recovery. Tool modification costs incurred due to late part design changes must be added to the amortized capital base.
Tracking cycle counts via non-resettable shot counters ensures accurate cost recovery verification across production campaigns.
