The Art & Science of Premium Doll Manufacturing
Producing an ultra-realistic doll requires a blend of old-world craftsmanship and modern technology. This 'behind-the-scenes' feature illustrates the process of doll manufacturing and the techniques used to create the most advanced companion dolls.
The Manufacturing Process Overview
Beginning at the design phase and ending with quality control, the process of doll manufacturing consists of the following stages:
- Sculpting & designing (2-4 weeks)
- Creation of the sculpting mold (1-2 weeks)
- Preparation of the materials (1-2 days)
- Casting the materials & curing (2-3 days)
- Assembly of the skeleton (1 day)
- Assembly of the body (1-2 days)
- Detailing & painting (3-5 days)
- Quality control (1-2 days)
- Final assembly & packaging (1 day)
Production Time:
Standard orders take 7-15 business days
Advanced customization orders take 20-30 days
