Cold Heading Routes and Cost Comparison
The upper gold route uses round wire; the lower blue route uses shaped wire. Both use the same model scale and viewing pace to compare shape development, in-die forming and transfer.
This animation tracks one blank along each route — approximately 9 stations for the round-wire route and approximately 5 stations for the shaped-wire route — following the PPT-based simulation scheme. The two machines shown are schematic illustrations of process routing only and do not correspond to actual machine models. The observation cadence has been uniformly slowed for clarity and does not represent the actual part-out cycle time in mass production; in steady-state multi-station equipment, multiple stations simultaneously process different blanks.
A more persuasive comparison: linking process path directly to conforming part cost
Preforming starts with the wire cross-section
This page’s solution reduces the station count from approximately 9 stations to approximately 5 stations, illustrating the concept of reducing subsequent external shape development steps. Whether the target part requirements can be met remains subject to verification via material testing, die design, FEM simulation, or physical die trials — this illustration is not actual production or FEM validation.
Check equipment capabilities before comparing quotations
If station reduction enables use of existing or more suitable equipment, equipment selection options may broaden. Procurement must compare tonnage capacity, cutoff range, ejection length, material transfer capability, and full-line quotation — pricing must not be based solely on number of stations. Creation Group does not guarantee cost savings, throughput improvement, or equipment suitability from station count alone.
Calculated based on equivalent annual conforming output
Record actual output, changeover downtime, utilization rate, and yield. Compare wire premium, equipment cost, tooling cost, labor cost, and energy consumption collectively. Whether shaped wire is economical depends solely on total conforming-part cost — no assumptions about throughput, scrap reduction, or automation benefit are implied or guaranteed.
Equipment specifications, quotations, and on-site data must be confirmed using consistent definitions.

Efficiency, equipment investment, and total cost calculation
Compare both routes using identical annual conforming-part demand. Upon first opening, cost and cycle time fields remain blank; missing items stay pending input. All monetary values are in RMB (Chinese Yuan); quotations must apply identical tax treatment — currency is never converted, and RMB remains the sole unit of account.
Current parameters are for demonstration only — not equipment quotations, actual production data, FEM simulation results, or guaranteed savings. After modifying some values, others may still derive from demonstration defaults; clear all before entering real data. This calculator does not constitute a technical review, process validation, or Creation Group commitment.

Formula, input definition, and calculation boundary
Conforming parts per hour = Stable gross output (pcs/min) × 60 × Operating utilization × Yield rate. Here, operating utilization accounts for unplanned operational losses excluding scheduled changeovers and setup; do not double-count changeover and setup time already listed separately — this calculation is not based on actual measured equipment performance.
Annual conforming capacity per line = Conforming parts per hour × (Annual available planned operating hours − Annual changeover & setup hours). Required operating hours = Annual conforming part demand ÷ Conforming parts per hour + Changeover & setup hours. If capacity is insufficient, no annual or per-part cost conclusions are generated; confirm whether additional lines or available hours are needed first. This page does not omit newly added equipment costs automatically — however, no throughput, uptime, or yield assumptions are guaranteed or validated.
Annual material input = Annual conforming part demand ÷ Yield rate × Blank weight ÷ 1,000,000 × Wire price per ton (RMB). Blank weight includes actual cutoff weight plus downstream losses for that route; scrap recovery revenue is not offset at this stage — this is a conceptual input, not a bill-of-materials or mill-certified weight.
Annual labor and electricity costs are calculated based on labor hours required to fulfill the same demand. Labor rate should reflect the portion allocated to this line; power consumption should reflect average actual draw under this operating condition. Annual tooling replacement cost excludes the initial set of tooling already listed separately; other variable costs (e.g., subcontracting, secondary annealing, cleaning) may be entered as per-conforming-part expenses — avoid duplication with previously listed cost categories. No labor rate, power draw, or variable cost is pre-validated or guaranteed by Creation Group.
Annual cost = Material + Labor + Electricity + Annual tooling consumption + Straight-line amortization of initial tooling + Straight-line amortization of equipment + Maintenance + Other variable costs. Per-part cost = Annual cost ÷ Annual conforming part demand. Total cash cost over comparison period = Initial investment (equipment + initial tooling) + Comparison years × Annual operating cost (excluding amortization); do not double-count capital expenditure and amortization. This cost model is illustrative only — Creation Group makes no ROI, breakeven, or cost-savings guarantee.
Assumes zero residual value, identical annual demand, and continuous operation under identical conditions — excludes financing costs, time value of money, tax differences, facility & utility overhead, unallocated idle labor hours, scrap recovery revenue, and any unmodeled production variability. Equipment procurement comparisons must verify full-line quotations, commissioning, and delivery terms within identical scope. Calculations represent static, scenario-based estimates only — not quotations, investment return guarantees, process validation, FEM simulation, or Creation Group commitments.
