7. Bill of materials
| Item | 100 | 1,000 | 10,000 |
|---|---|---|---|
| 7.1 304 stainless scoop head, cast/finished | $5.50-$7.50 | $3.10-$4.30 | $2.10-$3.00 |
| 7.2 Stainless tang / joint hardware | $0.85-$1.25 | $0.50-$0.75 | $0.35-$0.55 |
| 7.3 Glass-filled nylon handle core | $1.20-$1.80 | $0.65-$1.00 | $0.40-$0.65 |
| 7.4 TPE ergonomic overmold | $0.95-$1.45 | $0.55-$0.85 | $0.35-$0.55 |
| 7.5 Assembly, polishing and inspection | $1.35-$2.10 | $0.85-$1.35 | $0.60-$0.95 |
| 7.6 Retail carton / sleeve and inserts | $0.70-$1.10 | $0.40-$0.65 | $0.28-$0.45 |
| 7.7 Total landed ex-factory BOM | $10.55-$15.20 | $6.05-$8.90 | $4.08-$6.15 |
At 10,000 units, tooling adds about $2.80-$4.50 per unit, or 10%-16% of the $29 retail price. The $4.08-$6.15 BOM remains below 40% of retail before tooling.
8. Gates to clear
8.1 [DFM]
The cutting lip needs enough thinness to enter hard ice cream, but a too-thin cast edge will bend, chip or turn polishing into a cost bonfire.
Path: Run three head geometries through investment-casting trials, CNC edge finishing and freezer-load cycling; lock the lip radius after bend and scoop-force data.
8.2 [Certification]
There is no magic US appliance certification here, but every food-contact material and colorant still needs a clean paper trail.
Path: Use FDA 21 CFR-compliant 304 stainless, nylon and TPE grades; obtain supplier declarations, conduct food-contact migration review with a US lab, and complete California Proposition 65 screening.
8.3 [Tooling]
Dedicated casting and two-shot/overmold tooling is sensible at volume, but it is an expensive way to discover the grip angle was merely stylish.
Path: Use CNC and soft-tool prototype handles for ergonomic validation, then release production tooling only after a 500-1,000 unit pilot confirms demand and assembly yield.
9. Prototype sequence
- 9.1Create three scoop-head CAD variants with controlled lip radius, bowl depth and tang geometry.Penetration force, release behavior and bend resistance need measured tradeoffs, not freezer-aisle folklore.
- 9.2Build CNC stainless heads and 3D-printed or urethane-cast ergonomic handles.This quickly tests grip angle, reach, wrist posture and bowl geometry before committing to hard tooling.
- 9.3Run comparative scooping tests on standardized hard ice cream at freezer temperature and cycle the joint under load.Establishes scoop force, deformation, release and joint durability against incumbent scoops.
- 9.4Produce a 50-100 unit pilot using investment-cast heads and soft-tool molded handles.Validates casting finish, overmold retention, assembly time and real manufacturing yield.
- 9.5Complete food-contact documentation review, packaging drop checks and a 500-1,000 unit production pilot.Closes the routine US compliance and production-risk loop before spending $28,000-$45,000 on final tooling.
