About Irontech
Irontech is the main brand of a three-brand group which also includes Sigafun and Real Lady. Together they give a good, better, best path: Sigafun at the accessible end concentrating on toys and pleasure, Irontech in the middle with the widest range of TPE and silicone dolls, and Real Lady at the top with their most prestigious and realistic range. This collection covers Irontech only.
We have sold Irontech since 2018. Irontech has previously hosted the Silicone Lovers team at the Shenzhen exhibition and took us on a full tour of their factory. We have met the owner, Leonard, several times. Our most recent factory visit was in September 2025. We have seen the moulds, the silicone pouring, assembly, face makeup, painting, hair implantation and observed their Quality Assurance process. During that visit we also saw a prototype of what became the IronAI Bionic VaginaX, well before it was released.
One thing that stayed with us from talking to Irontech’s CEO is how he describes his role. He told us he understands that a customer who buys a doll is trusting him to bring it into their home, often as a member of their family, so he cares about durability. Skeleton and silicone durability are things he is genuinely focused on, and that is not the kind of thing you typically hear from a CEO.
Our close relationship has led to an exclusive Irontech doll made especially for Silicone Lovers, the 167cm Plus (see Nabi and Yeona).

The Irontech group
| Brand | What it is | Best for |
|---|---|---|
| Sigafun | Irontech group brand focused on fun: TPE toys, torsos and some full-size dolls. | The most affordable way into the Irontech group. Suits buyers that want to experience before committing to a more expensive doll. |
| Irontech | The main brand. Core TPE and core silicone ranges, with several series. | Feature-rich realism with a wide choice of bodies, faces and upgrades. |
| Real Lady | The luxury tier. Best makeup, more paint layers, bodies scanned from real women, RST by default. | Buyers who want the finest realism in the group. |
What Makes Irontech Different?
Irontech is the brand to look at if you want features as well as looks. Four things stand out.
First, range. With more than 550 dolls across TPE and silicone, there are heights, builds and faces for most tastes, and the group's own brands let you move up or down in price without leaving the ecosystem.
Second, Ultra Light Weight (ULW) technology, which makes large silicone dolls noticeably easier to move while keeping them soft.
Third, technology. Irontech offers what we believe is the widest range of robotic upgrades available, and its IronAI system is among the most advanced we have seen.
Fourth, targeted softness. Upgrades such as soft thigh, soft belly and a soft vagina are options others do not typically offer. And when something is a problem, Irontech adapts quickly. Reinforced joints, thicker steel tubes in the skeleton and better packaging are examples of recent fixes.
Understanding the Irontech Series
The model name tells you which series a doll belongs to. The height is always first, and the suffix identifies the series.
| Series | Look and body | Code in the model name | Best for |
|---|---|---|---|
| Irontech silicone (core) | Many stylised and fantasy-leaning body shapes. The best seller. | Height only, for example 164cm | Buyers who want variety and features. |
| Natural Optimized | More anatomically accurate bodies, scanned more closely from real women. | T after the height, for example 165T | A more natural body shape. |
| Wonder Dolly | K-pop-inspired heads on Naturally Optimized bodies. | T after the height, for example 158T | A stylish, modern look with natural bodies. |
| Young Series | Designed to occupy the space between traditional anime styles and realistic human faces. | No code, look for [Young Series] in the product title | Those that want an anime inspired 3D face |
| Dream Girl Bailey | Bimbo-style fantasy proportions. | BA after the height, for example 158BA | Exaggerated proportions. |
| Oriental | Elegant, anatomically realistic Asian & Japanese beauties. Irontech's best, with its unique softness technology. | Oriental in the product name | Buyers who want the best Irontech offers. |
Some heights also come in a Plus and Minus version, which is not a series. It is a way to separate two dolls of the same height that use different moulds. For example, the 163cm Minus has smaller breasts and the 163cm Plus has larger ones. The Irontech silicone core range is the best seller by a distance, because the other series are more niche.
Why Choose Irontech?
Choose Irontech if you want a premium silicone doll with options, for example ULW, ROS Max or gel upgrades. Choose it if you like to choose your own combination of body, face and upgrades from a very large selection. Choose it if technology matters to you, from robotics to AI. And choose it if you want a doll with a clear upgrade path through the group: Sigafun for budget, Irontech for the middle, Real Lady for the top.
Customers tell us they love the curves, the softness and the faces. The heads that come up most often are Celeste, Celine, Hedy and Suki.
Materials & Build Quality
Inside the Irontech brand there is its own good, better, best ladder: TPE is good, silicone is better, and the Oriental series is the best. Each Irontech silicone doll has 19 layers of paint when choosing the S makeup option, and the oriental series builds on this realism by having their own exclusive softness options.
Irontech's TPE line deserves an honest note. It has had less development than its silicone for some time, and WM's TPE is ahead on technology. If TPE is your priority, compare before you decide. If you want Irontech, silicone is currently where the brand is strongest. Our Silicone vs TPE Guide explains the trade-offs. If you are interested in Irontech TPE, their Sigafun brand is where they’re actively developing new TPE products.
How the softness upgrades work
The softness options can confuse people, so here is how they fit together. Standard silicone is the base. You can add gel breasts and a gel butt. If you then add the ultra soft skin upgrade (ultra soft silicone), the gel breasts become softer gel breasts, and the gel butt becomes a softer gel butt. So the path to softer gel breasts is gel breasts plus ultra soft skin.
There are also targeted upgrades for the thighs, belly and vagina. If you choose a removable insert vagina with the soft vagina upgrade, the insert is made softer, just as the fixed version would have been.
A caution: the softer a doll gets, the easier it is to damage. Soft is wonderful, but it is a trade-off with durability, so choose it for the areas where you want it most.
Oriental series only
Three technologies belong to the Oriental series exclusively: CloudTouch silicone (softer, finer silicone), AquaBounce (a more elastic breast and butt filling) and GraceJoint (an advanced finger skeleton). They do not apply to the rest of the range.
Signature Technologies
Ultra Light Weight (ULW)
ULW reduces a doll's weight while keeping its softness. It is not a hollow body or a hard foam fill. Irontech changes the internal structure and the manufacturing process, using slower injection, faster curing and a five-stage variable-speed pour. Irontech reports an average reduction of around 20%, with individual bodies ranging from about 11% to 31%. Its own figures are in the table. We were able to see the moulds and pouring process on our factory visit, although ULW arrived after it.
| Model | Before ULW (kg) | After ULW (kg) |
|---|---|---|
| 153 | 34.6 | 27 |
| 162P | 55.8 | 42 |
| PR178 | 48.5 | 36 |
| LN164 | 59.8 | 43.2 |
| PR190 | 80 | 55 |
Figures supplied by Irontech. Reductions vary by body, configuration and production batch.

ROS versus ROS Max: What’s the difference?
ROS gives a doll a built-in jaw and oral structure. ROS Max is an Irontech exclusive technology and is a clear upgrade. Teeth, tongue and tonsils are more lifelike, and the teeth sit naturally against the lips. The eyes keep their shape whether the mouth is open or closed, and can even be adjusted to partially close the eyes to give more expression. The jaw hardware has been moved so that adjusting is easier and the jaw stays where you put it. The head is also about 0.5kg lighter (around 2kg in total) and has a reinforced inner frame. A note: adjust expressions gently with your fingertips and gloves, to avoid damaging silicone or makeup.

EVO skeleton
The EVO skeleton uses stainless steel with double-jointed limbs and shrugging shoulders for natural posing. Irontech has strengthened certain joints and moved to thicker steel tubes after earlier issues, and has upgraded its packaging as well. Real Lady has a further improved version, the EVO Max 2.0, which is covered on its collection page.
Robotic upgrades and IronAI
Irontech's robotic options include a suction vagina, suction mouth, oral heating, auto oral (head/neck bobbing) and moving hips (waist spin sex bot). The newer IronAI Bionic VaginaX senses movement and responds with heating, squeezing, suction and vibration, and learns over time. We cover it in detail in our Bionic VaginaX article.
Three things to know. Robotics add weight, as the table shows. The Bionic Vagina's depth is about 13cm, and the anus cannot be used with it. And the AI voice conversation needs a subscription, while the Bionic Vagina's core functions do not.
| Upgrade | Approximate added weight |
|---|---|
| Auto oral (head bobbing) | about 10kg |
| Moving hips (waist spin) | about 5kg |
| Both together | about 15kg |

Design Style
Irontech covers more of a range of looks than concentrating on any single look. You will find athletic bodies and curvy bodies, stylised fantasy shapes and natural looks scanned from real women. The silicone range is realistic, and the Oriental series leans towards elegant Asian beauty. Customers describe the faces as beautiful, and they love the curves and the softness.
Irontech is the brand which makes the most comprehensive range of male dolls we sell, with several bodies and heads, multiple penis options, including the Pulse Throb Penis and specialized upgrades such as implanted facial, goatee and body hair. We cover them on our male sex dolls collection.
Licensed Pornstar Series
Irontech's Pornstar Series is a small range of four dolls based on adult performers who have licensed their names and likenesses for the project: Cliff Jensen, Drake Von, Violet Voss and Eila Adams. Each product page shows its own options and details – these dolls have slightly less options than normal as they are a licensed likeness of a real performer. If you would like help choosing between them, or want to know which upgrades suit each doll, ask our team before you order.
Buying Experience
The questions we hear most are about what the “minus/plus”, “T” or “BA” stand for, and questions about other series such as what “Naturally Optimized” or “Wonder Dolly” mean, how the softness upgrades combine, and what each upgrade adds to the weight. We spend time discussing weight with Irontech buyers we speak to, especially if robotics are involved, because the 15kg from both robotic options changes how a doll is handled and stored.
The most common mistake is stacking the softest options without realising the trade-off in fragility. Buyers also compare Irontech with Zelex, and we are happy to talk through the differences with you - just get in touch!
Who Should Buy Irontech?
Irontech suits buyers who want features and choice. Beginners can start with their TPE range or one of their core silicone dolls, and move up to higher realism later. Technology fans get the broadest robotic and AI options on the market. Larger-body buyers benefit from ULW. Collectors can pick from a very large range of faces. If you want the finest realism and the best paintwork in the group, step up to Real Lady. If you want to spend less, look at Sigafun or Irontech TPE. Our First Time Buyers Guide is a good place to start.

Our Thoughts
Irontech's strengths are range, features and technology. ULW, ROS Max, the targeted soft upgrades and the robotic and AI options are real differences, and the group structure gives buyers a path at several price points. Irontech also fixes problems quickly, which matters to us.
The limitations are honest ones. Irontech's TPE line is behind WM's TPE on technology, for example, a lack of STPE which is only found in their Sigafun range. Some of the best realism is understandably limited to the Oriental series or to Real Lady price range. Soft upgrades trade off against durability, robotics add weight, and the Bionic Vagina has limits on depth and anal use.
Irontech suits buyers who want features and choice. It is a good fit between entry-level silicone and the luxury tier, making them an excellent first choice if you’re considering a first silicone doll. If you want the finest realism, look at Real Lady or Fanreal. If your priority is a low price, look at Sigafun.
