In the field of high-end doll manufacturing, skeleton coated silicone products, with their unique craftsmanship and superior quality, are becoming the mainstream choice in the collectible doll market. As a professional manufacturer of liquid silicone molding, we are committed to providing one-stop skeleton coated silicone solutions from design to mass production.

I. What is Skeleton Coated Silicone?

Skeleton coated silicone, fully known as steel skeleton liquid silicone encapsulation molding process, is a manufacturing technology that completely wraps a precision-designed metal skeleton (steel bone) inside food-grade or medical-grade liquid silicone. Dolls manufactured through this process not only have the soft touch and delicate texture of a real human body but also possess multi-joint mobility brought by the metal skeleton. Therefore, they are also called "steel bone movable dolls" or "coated silicone movable dolls."

Compared with traditional doll manufacturing processes, skeleton coated silicone technology has significant advantages. Traditional dolls often use hard plastic or resin materials with exposed joints, which greatly reduces visual appeal. The coated silicone process completely hides the mechanical joints inside the soft silicone material, making the appearance more realistic and natural without affecting the range of motion.

II. Core Manufacturing Process

1. Steel Skeleton Design and Manufacturing

The steel skeleton is the core structural component of skeleton coated silicone products. We use high-strength stainless steel or alloy steel materials, through precision CNC machining and assembly processes, to manufacture metal skeletons with multiple degrees of freedom joints. Each joint undergoes rigorous life testing to ensure stable damping and positioning capabilities even after tens of thousands of movements.

2. Liquid Silicone Formula Development

We have our own R&D liquid silicone formula system that can adjust silicone hardness, elasticity, wear resistance, and touch according to different product requirements. Food-grade silicone materials are non-toxic, odorless, non-allergenic, and aging-resistant, making them very suitable for high-end collectible doll manufacturing.

3. Precision Mold Manufacturing

Molds are the key to ensuring coating molding precision. We use high-precision CNC machining centers to manufacture molds, with specially treated mold surfaces to ensure smooth and delicate silicone surfaces with clear textures after molding.

4. Injection Molding Process

Using advanced liquid silicone injection molding equipment, liquid silicone is injected into precision molds under precisely controlled temperature and pressure conditions.

5. Surface Treatment and Painting

After molding, the skeleton body undergoes multiple surface treatment processes including deburring, surface polishing, cleaning, and drying. Subsequently, experienced painting technicians perform skin tone spraying and detailed finishing.

V. Why Choose Liquid Silicone Coating?

Liquid silicone coating has irreplaceable advantages over traditional methods. Liquid silicone has excellent fluidity that can fill extremely fine mold textures, making product surface detail far superior to traditional processes. Silicone material has excellent elasticity and toughness, and will not crack or deform even after tens of thousands of bends. Furthermore, silicone material has good biocompatibility with no irritation to human skin.
