④ ROS MAX Head (Next-Generation Real Oral Structure)

Overview: The ROS MAX Head represents the latest generation of IronTechDoll head technology, combining enhanced realism, improved engineering, reduced weight, and superior structural stability.

(1) Optimized Oral Positioning

The teeth have been repositioned slightly below the lips. When the mouth is closed, the teeth remain naturally hidden. When opened, the teeth become subtly visible while the tongue gently rises, creating a more lifelike appearance similar to natural open-mouth breathing.

(2) Upgraded Eye Socket Structure

A newly developed lower eyelid support structure has been added to improve eye-area stability and minimize facial deformation caused by jaw movement.

(3) Improved Mouth-Opening Mechanism

The redesigned jaw system provides better support and a more realistic feel. The mouth can be opened smoothly with a gentle pull, creating a refined and natural movement.

(4) Reduced Head Weight

Compared to the standard ROS Head, ROS MAX is approximately 0.5 kg lighter (around 20% lighter overall), reducing the total head weight to approximately 2.5 kg and making posing and photography easier.

(5) Compatible Head Models

S Series: S1, S10, S13, S14, S17, S19, S20, S27, S30, S31, S32, S33, S40, S44, S55, S56
B Series: B1, B2
T Series: T1, T3, T4
A Series: A3, A4, A5, A6

IronTechDoll ROS Head vs ROS MAX Head Oral Structure Comparison Guide

IronTechDoll’s ROS and ROS MAX heads represent two of the brand’s most advanced oral structure head types, designed to deliver highly realistic mouth detailing and natural jaw movement performance.

The ROS Head is already a well-established and widely recognized oral structure head type that has been proven in the market for its realism and stability. In contrast, the ROS MAX Head is a fully upgraded version built on this foundation, featuring improved internal structure design, enhanced jaw mechanics, and more natural mouth-opening performance, resulting in a significantly more refined realistic experience.

In the demonstrations below, you will clearly see the differences between the two systems in terms of mouth design, jaw movement, internal detailing, and overall realism. However, this section places stronger emphasis on the ROS MAX upgrade, which delivers improved facial stability, enhanced realism, and more natural visual performance from multiple angles.

From the proven and stable ROS head type to the next-generation ROS MAX upgrade, this comparison will help you clearly understand the differences and see why ROS MAX is considered the most advanced option currently available.
