Small-Batch Production: Prototype vs. Mold Making

Short Intro:

During product development, small-batch trial runs often face a crucial decision: should we adopt traditional mold making or the latest prototype technology?

As a professional service provider with over a decade of experience in the industry, Gaofeng Prototype Factory has served over 3,000 clients. We’d like to explain the key factors in this decision from the perspectives of cost, efficiency, and quality.

1, Cost Dimension Comparison

Core cost structure differences

Cost ItemsMold productionPrototype CraftSuitable for scenes
mold costs3-1 million yuan+0 $Order โ‰ค 300 pieces
Cost per piece trendThe larger the batch, the better the dealMaintaining basic stability50-200 pieces are the best
Design change costsReopening mold (10,000 yuan level)Modify drawings onlyProduct unfinished period

Gapfemg’s experience: Silicone mold re-molding has the lowest cost per piece for production between 50 and 200 pieces. However, for production exceeding 300 pieces, the total cost may exceed that of traditional mold making due to the limited lifespan of silicone molds (approximately 10-15 times).

2, Time Efficiency Comparison

ProductionMold productionPrototype Craftefficiency gap
Preliminary preparation15-30 daysLaunched on the same daySave 2-4 weeks
Production cycle1-3 months1-7 days5-10 times faster
Design Iteration1-2 weeks24 hours80%+ faster

Actual application scenarios:

A consumer electronics customer needed 100 sets of prototypes 10 days before the exhibition, and they were delivered in 7 days through CNC+vacuum molding.
Medical device companies used 3D printing to produce samples within 24 hours and quickly complete clinical verification

3, Process Adaptation Matrix

Process TypeApplicable ScenariosAccuracy rangeAdvantages
CNC machiningload-bearing structural partsยฑ0.05mmMetal parts first choice
Silicone moldAppearance verification documentยฑ0.2mm50-200 pieces are the best
3D printingComplex internal componentsยฑ0.1mm24-hour delivery

Important Notes:

The surface of 3D printed parts is rough, so use with caution on high-finish parts.

Silicone mold has a 0.3% shrinkage rate, so precision assembly needs to be compensated in advance.

Metal 3D printing is more expensive and more suitable for special applications.

Gaofeng’s Four-Step Decision Model

Classification by quantity:

โ‰ค50 pieces โ†’ CNC | 50-200 pieces โ†’ Duplication | 200-500 pieces โ†’ Mixed process

On-demand matching:

Structural parts โ†’ CNC | Appearance parts โ†’ 3D polishing | Flexible parts โ†’ Silicone mold

Cost Optimization:

15% reduction in material pre-purchase | Free access to shared mold library

Process control:

Real-time tracking | Customers can view order production progress in real time

Small batch production core concept

We recommend: use prototypes to control risks before product verification, and use open molds to expand benefits after demand stabilizes.
