Hard Silicone Head vs. Soft Silicone Head

Hard Silicone Heads  Holds fine facial details with high precision Extremely resistant to wear and deformation Ideal for implanted hair and brows—features stay firmly in place Delivers a sharp, realistic appearance over time No oral function

Soft Silicone Heads Soft, skin-like texture for natural touch Allows for oral functionality, enhancing realism Less suited for hair implantation (some brands now offer it) Best for users seeking tactile authenticity

Silicone ROS Head vs. ROS MAX Head

ROS Head vs. ROS MAX Head

Irontech is pushing the boundaries of realism with a broadened lineup of ROS-enabled silicone heads, now tailored to suit a wider range of aesthetic preferences and functional needs.

Now Available:

🔹 S-Series (ROS Optional): S1, S17, S18, S20, S26, S29, S37, S40
🔹 T/R-Series (ROS Included by Default): T3, T4, T5, R6, R7

Skeleton

EVO Skeleton
Irontech Doll uses a durable, impact-resistant EVO skeleton designed to offer improved stability without sacrificing flexibility. The EVO frame supports shoulder-shrugging, and its elbows and knees include partial double joints, allowing for more advanced and expressive posing. If you enjoy doll photography or want smoother, more dynamic interaction, the EVO skeleton is an essential upgrade.

Skeleton Tightness Options
(1) Standard – The Most Popular Choice
The standard-tight skeleton offers a well-balanced level of resistance, making it the preferred option for most users.

(2) Tight – Ideal for Photographers
A tighter joint structure slows down wear caused by frequent repositioning, making it especially suitable for photo sessions and detailed posing.

(3) Loose – Best for Intimate Interaction
A fully loose skeleton provides the easiest, most natural movement, favored by users who prioritize relaxed handling and frequent pose adjustments during close-contact moments.

Ultra Lightweight Technology (ULW) – Lighter Irontech Doll Bodies

Irontech Doll Ultra Lightweight Technology (ULW) is a new lightweight body option designed to reduce the overall weight of the doll while maintaining a soft and realistic feel. With an average weight reduction of around 20%, ULW makes larger Irontech dolls easier to handle, move, transport and use in everyday situations without sacrificing the realistic experience.

Key Benefits of Ultra Lightweight Technology

• Around 20% average weight reduction compared with a standard body configuration.
• Soft and realistic feel is maintained despite the lower overall weight.
• Designed for realistic interaction without sacrificing the natural experience of the doll.
• Easier handling and transportation, especially with larger and heavier Irontech doll bodies.
• More convenient everyday use thanks to the reduced body weight.

Weight is one of the most important considerations when choosing a large realistic doll. Heavier bodies can be more difficult to move, position and transport. ULW technology helps reduce these weight-related barriers, making larger body sizes more practical for customers who want easier handling while retaining the softness and realism expected from an Irontech Doll.

Hard Hand & Standard
The Hard Hand option uses a firm silicone layer on the outer surface of the hand, designed to prevent the internal finger bones from breaking through the skin.
Please note: When choosing Hard Hands, faint discoloration lines may appear. This is a natural effect caused by combining two silicone materials with different properties. Since the materials vary in softness and function, slight transitions are unavoidable. These lines are purely cosmetic and do not affect durability, structure, or overall performance. The hand remains strong, well-protected, and realistic to the touch.

Standard Hand vs. Hard Hand 

Ball-Jointed Hand Skeleton vs. Articulated Finger Joints

1. New Ball-Joint Wrist – Provides greater rotation and improved flexibility.

2. Reinforced Fingertip Design – Rounded tips offer better puncture resistance and longer lifespan.

3. Cylindrical Finger Bones – More realistic shaping with enhanced structural strength.

4. Improved Joint Smoothness & Stability – Reduces wobbling and helps maintain tightness over time.

5. Enhanced Surface Treatment – Better silicone adhesion increases durability and prevents internal shifting.

In terms of movement, traditional Articulated Finger Joints cannot bend laterally, while the Ball-Jointed Hand Skeleton allows multi-directional motion, resulting in significantly better flexibility.

Softened & Gel Body Parts

Softer Thigh replaces the padding in the doll's thighs with softer silicone, giving you a softer feel.

Standard & Gel & Softer Gel Butt

Use gel to fill the doll's bull to make it soller. We recommend wearing the doll with light-colored shapewear to preserve its shape during regular use.

Gel butt (+2~4kg) should not be left in a sitting or unnatural position for extended periods. When not in use, please either hang the doll or place it back in its original box for safe storage.

The difference between Gel Breast and Softer Gel Breast lies in the filling. Soller Gel Breast is softer.

Irontech Doll Bionic VaginaX – New Smart Bionic Function

Irontech Doll Bionic VaginaX is a new optional function for Irontech silicone dolls. Unlike traditional suction-based systems, Bionic VaginaX uses a flexible sensing system and bionic structure designed to provide more natural interaction and intelligent response. The system combines real-time sensing with adjustable functions and is now available to order for Irontech silicone female dolls.

Key Features of Bionic VaginaX

• Multi-dimensional sensing: detects usage status, speed, depth, duration, rhythm and other signals.
• Bionic wrapping system: the flexible bionic structure is designed to create a more natural and comfortable wrapping sensation than traditional negative-pressure systems.
• Heating, contraction and vibration: several functions are integrated into one system for a more advanced interactive experience.
• Smart AI interaction: works with the Irontech smart AI system to process sensor signals and provide intelligent feedback.
• APP adjustment: sensitivity and tightness can be adjusted through the app according to individual preferences.

Its combination of sensing technology, bionic construction, heating, contraction, vibration and app-based adjustment expands the available customization options for Irontech silicone dolls.

Important compatibility information: when Bionic VaginaX is installed, the doll's anal function is no longer available. This should be taken into account when choosing the final doll configuration.

Robot Functions

Standing Feet (With Blots) & Standing Feet Without Blots

Standing Feet have metal bolts attached to the footplate that can hold the doll's weight, allowing it to stand without damaging the material under the feet. Standing Feet Without Bolts is a newer option where the feet material is harder ed to support the doll's weight, but it looks like normal feel and feels much harder. However, standing for an extended period, particularly without support, can still lead to damage at the bottom of the feet.

*Please note that when selecting the Standing Fool without bolls option, sublle lines of discoloration may appear on the doll's feel. This is a natural result of combining two types of silicone materials with different levels of softness for enhanced curability and function. These lines are unavoicable due to the transition between materials, ensuring the doll's structure remains strong while providing a more realistic feel. They are purely cosmetic and do not affect the doll's overall quality or performance.
