Silicone mannequins are lifelike human form or body part models made primarily from liquid silicone rubber through an infusion molding process. Leurs principaux avantages résident dans un réalisme et une élasticité ultra-élevés, leur permettant de reproduire de minuscules détails comme la texture de la peau, lignes musculaires, même les empreintes digitales et les vaisseaux sanguins. Aujourd'hui, ils jouent un rôle essentiel dans les soins de santé, film, éducation, and consumer goods—but how are they made, and what makes them stand out?
1. Core Performance: How Silicone Mannequins Compare to Traditional Models
Traditional mannequins (par ex., plastique, gypse) often lack flexibility and realism. Silicone versions, par contre, excel in six key areas. The table below breaks down their performance:
| Performance Characteristic | Specific Manifestation | Advantage Over Traditional Models |
| Realism | Replicates pores, wrinkles, blood vessels; touch matches real skin | Traditional models have rough surfaces and no texture details |
| Flexibilité | Résistance à la traction: 3–10MPa; allongement à la rupture: >500%; no permanent deformation after bending | Plastic/gypsum models are brittle and easily crack |
| Résistance aux intempéries | Résistant aux UV; no cracking after 3 années d'utilisation en extérieur | Plastic fades quickly; gypsum dissolves in moisture |
| Chemical Stability | Résiste aux acides, alcalis, huiles; disinfected with alcohol safely | Traditional models corrode or deform with chemicals |
| Breathability | Adjustable air permeability | Ideal for long-term skin contact (par ex., prosthetics) |
| Durabilité | Withstands repeated use without surface damage | Gypsum models chip easily; plastic yellows over time |
2. Step-by-Step Production Process of Silicone Mannequins
The manufacturing of high-quality silicone mannequins follows a strict 3-stage workflow. Each step directly impacts the final product’s realism and functionality:
Stage 1: Prototypage (Laying the Foundation)
- Data Collection: Use a 3D scanner to capture a digital human surface model, or create a mold directly from a real person (for custom projects).
- Trim Optimization: Smooth scanned data to fix imperfections (par ex., uneven edges) and enhance key features (par ex., facial contours).
- Print Transition Molds: 3D-print resin or gypsum molds—these act as carriers for silicone pouring later.
Stage 2: Silicone Blending & Verser (Creating the Core Structure)
- Sélection des matériaux: Choose silicone with hardness ranging from Shore 0–80 degrees based on use cases. Pour applications médicales, sélectionner medical-grade silicone that passes biocompatibility tests.
- Proportional Mixing: Mix two-component silicone with a curing agent in a precise ratio, then use vacuum stirring to remove bubbles.
- Layered Pouring: D'abord, brush a thin silicone layer on the mold to boost adhesion; then pour silicone in bulk to fill the mold.
- Curing Control: Cure at room temperature for 8–24 hours (or heat to shorten to 2–4 hours). Avoid extreme temperature differences to prevent deformation.
Stage 3: Post-traitement (Adding Realism & Fonctionnalité)
- Release Stripping: Carefully separate the silicone model from the mold; use a release agent if stuck.
- Detail Carving: Manually refine microstructures (par ex., adding subtle wrinkles) and spray skin-tone pigments for lifelike color.
- Functional Integration: Embed components like sensors or heating wires (par ex., for temperature-controlled rehabilitation mannequins).
3. Typical Application Fields: Where Silicone Mannequins Shine
Silicone mannequins are versatile—here are their most impactful use cases, organized by industry:
| Industrie | Applications clés | Real-World Example |
| Soins de santé | Surgical simulation, rehabilitation aids, prosthetic fitting | A customized tumor resection model helps surgeons practice anatomical structures before real operations. |
| Film & Television | Special effects makeup, wax figure production, motion capture | Silicone “scar” or “monster skin” bases for movie characters; lightweight internal supports for celebrity wax figures. |
| Dessin industriel & Éducation | Tests de produits, teaching demonstrations, cultural relic restoration | An ergonomic model for handheld tools to test grip comfort; touchable anatomy organ models replacing gypsum specimens. |
| Personalized Consumer Goods | Custom accessories, sports protection, pet supplies | Baby hand/footprint pendants; athlete joint protectors shaped to their movement; non-slip paw covers for elderly pets. |
4. Common Problems & Solutions in Production
Even with careful manufacturing, issues can arise. Below is a troubleshooting guide for the most frequent problems:
| Problem Phenomenon | Root Cause | Practical Solution |
| Bubbles in the silicone | Insufficient stirring or too-fast pouring | Utiliser vacuum defoaming before pouring; slow down the pouring speed. |
| Local softening of the model | Uneven dispersion of curing agent | Extend mixing time to ensure uniformity; refill the soft area with fresh silicone for a second cure. |
| Color deviation from the target | Wrong pigment mixing order | Mix and adjust pigments first, then add the curing agent (add pigments in small batches to avoid overshooting). |
| Shrinkage or deformation | Concentrated heat release during curing | Utiliser layered pouring to spread heat; pre-cure at a low temperature (par ex., 30–40°C) before full curing. |
5. Yigu Technology’s Perspective on Silicone Mannequins
Chez Yigu Technologie, we believe silicone mannequins are more than just “models”—they are bridges between innovation and real-world needs. In healthcare, our custom medical-grade silicone mannequins have helped train over 500 surgeons by simulating rare anatomical cases, reducing surgical risks. For film clients, our fast-curing silicone solutions cut special effects production time by 40% without compromising realism.
Looking ahead, we will focus on two directions: 1) Developing smart silicone mannequins with built-in pressure sensors (for prosthetic fitting accuracy) et 2) Improving eco-friendly silicone materials to reduce production waste. We aim to make silicone mannequins more accessible and impactful across industries.
FAQ
- Can silicone mannequins be reused, and how to maintain them?
Oui, they can be reused for years with proper care. Clean them with water and dry in the shade (avoid sharp objects). Store in a cool, dry place away from direct sunlight, and apply neutral conditioners (par ex., petroleum jelly) regularly to prevent surface cracking.
- What type of silicone is best for children’s toy-related mannequins?
Choisir food-contact-grade silicone—it is non-toxic, meets safety standards (par ex., FDA), and is soft enough to avoid harming children. Pair it with non-toxic pigments and polishers during production.
- How long does it take to make a custom full-body silicone mannequin?
For a standard full-body model, the process takes 7–10 days: 2 days for prototyping, 3–4 days for silicone mixing/curing, et 2 days for post-processing. Commandes urgentes (using fast-curing silicone) can be completed in 4–5 days.
