ABOUT IRONTECH DOLL

Irontech is a Chinese brand of technologically advanced and attractively priced TPE and silicone dolls.

All bodies feature an upgraded skeleton which includes: 

• a double hinged neck articulation ensuring stability and a wide range of poses

• the lock-up head attachment system. The head is fixed by pushing down to click rather than rotating as in the traditional attachment system.

Here's a demonstration video about how to use this connector:

• shrugging shoulders as a default

All dolls are supplied with a practical hanging kit, to allow upright storage: Comparison picture of Irontech Doll TPE skin colors, to help you decide the right skin color:  

Gel-filled breasts

Now breasts with gel implants are the default option on silicone dolls. They are a fee-paying option on TPE dolls.

Articulated fingers

This is a fee-paying option. Find out more here.

Implanted hair

Now synthetic implanted hair available on silicone heads. Please note that implanted hair requires an extra two weeks production time.

Soft silicone heads

When you buy a silicone doll you can choose between regular hard silicone head and softer silicone head. Check here for a short comparison video. The soft silicone head has an opening and can allow oral sex. On the other hand, this head cannot have implanted hair or implanted eyebrows, and it will be slightly less detailed than the 'regular silicone' one.

Real Oral Sex (ROS and ROS MAX)

Some silicone heads can enjoy an upgraded mouth with movable jaw (click here for a demo video of this feature). The upgraded mouth is the default option on heads: Miya, Luna, Suki, Hazel, Hedy, Fenny, Aileen, Yeouna, Nia, Evie, Sasha. Some of these heads can be ordered without ROS. In this case there's no surcharge to be paid. Please get in touch if you'd like to order one of the heads mentioned here without ROS. ROS heads softness is somehow half way between the 'regular' and the 'soft'. Please choose the 'soft' option in customization. ROS heads can have implanted hair and eyebrows. Please contact us if you'd like to add implanted hair and eyebrows to your order. As of September 2023, the above ROS heads can also be equipped with an 'electric' ROS feature with integrated 'moaning'. This robot-like ROS is a fee-paying option. You can see here a presentation video. From June 2025, the first ROS MAX heads are introduced, the first major upgrade of the ROS launched in 2022. Here are some presentation videos: video 1, video 2, video 3. As of July 2025, the ROS MAX heads are: Celine - Miku - Suki - Ivy - Rita - Vivian - Kitty - Penny
