A Comprehensive Guide of Sex Dolls

I. What is a Sex Doll?

A sex doll is a life-like solid doll produced from TPE or silicone materials, which imitate human skin, combined with an alloy framework, which imitates the human figure. The doll can be positioned in positions like that of a human, which can serve as adult entertainment as well as for collecting.

II. The Evolution of Sex Dolls!

Historical records indicate that the origins of sex dolls date back to the 17th century, when Dutch sailors created leather dolls through hand-sewing to meet their sexual needs. Sailors used to feel loneliness when sailing across the oceans, and thus, these gadgets came into existence.

Later, during World War II, Hitler, to avoid sexual relations between the German military and women of “non-Aryan” blood residing within the occupied 5th districts, and also to control the spreading of sexually transmitted diseases within the Nazi military, secretly commissioned the making of inflatable dolls modeled after the female body to fulfill the burning needs of the German military. This becomes the first reason for the existence of inflatable dolls.

Hitler gave particular emphasis to this, with very specific requirements listed by the inflatable dolls: “She must have all the sexy attributes of a young woman,” namely “fair skin, golden hair, blue eyes, 1.76 meters tall, with full lips and a voluptuous bust.”Unfortunately, this aim remained non-actualized. With the German army’s retreat and the bombing of Dresden, where the inflatable dolls were manufactured, this aim was aborted, causing the inflatable dolls to be long overdue. Years later, when it came to the Vietnam War, the United States duplicated this aim by giving out many inflatable dolls to the front-line soldiers, who received them well!After this, inflatable dolls didn’t fade out but became more prominent in our world.

The origin of the development of the silicone doll comes from the fast-growing sex toy industry in Japan towards the end of the 20th century. For the first time, the use of the word "silicone" gave rise to the production of lifelike dolls, characterized by their closer semblance to reality in terms of look and feel. This resulted in the entry of these dolls into the world, exposing the new phenomenon in the world. The market at that time required very high technical expertise in addition to very costly raw materials. As a result, the use of the current "silicone doll" in the market at that time made the item a "luxury" in the lives of people due to the price of tens of thousands of "yuan." The growth in the industry was followed by advancements in local technology, giving rise to new raw materials. This breakthrough in the market finally resulted in the entry of the Chinese manufacturer of the "silicone doll" at the price of a few "thousand" "yuan." These have since then become a normal accessory in our lives. The current "silicone doll" in the market signifies the growth in the use of the item from a sex toy to a much lifelike doll in terms of its perception and intelligence.

Maybe we just can’t continue along this path. Although it is possible to name the “inventor of the sex doll,” the creation of such a toy is just a symbol of the complex needs of humans. “From a desperate act in the wake of war to the integration of technology and emotion and the clash of business and conscience,” I firmly believe that “the ‘she’ we dream of is just around the corner and soon is sure to make its presence known in our midst.”

III. The Composition of a Sex Doll!

A sex doll has three components: skin, skeleton, and head sculpt.

Skin:
The outer covering of a sex doll is known as the skin. The two most dominant materials found in sex dolls are silicone as well as TPE. TPE can be described as quite soft with a texture resembling human skin. Its appearance is not as natural as silicone. The texture of the skin is finer with a natural appearance compared to TPE. It is quite hard.

Skeleton: This is the bionic skeleton that has the ability to move like the human skeleton. It can be made from stainless steel and aluminum. Others may use alloy materials. They work to provide support for the doll’s body to allow the doll to assume different postures. Skeletons come under the four major classes: standard, yoga, soft, and hard skeletons.

Head sculpt: This is the head of the sex doll that is composed of TPE and silicone. TPE head sculpts are soft and allow a mouth to be added, but hair implants are not allowed (only wigs). Silicone head sculpts are comparatively more reality-appealing than TPE head sculpts and allow hair and eyebrows to be added to them but are comparatively harder (softer silicone head sculpts are available with fake mouths that are softer than TPE).

IV. Material Classification and Features of Sex Dolls!

The current trend among sex dolls is that they are comprised of two types of materials: TPE and silicone.

The full form of the first material, “TPE,” represents “Thermoplastic Elastomer.” “Elastomer” in full form is “TPE.” An elastomer or a Thermoplastic Elastomer

It is a combination of the excellent properties of conventional cross-linked vulcanized rubber materials, such as high elasticity and strong resistance against aging, and the easy process for common plastics. The material is environmentally friendly, safe, widely applicable, highly colorable, has a good touch, good weather resistance, fatigue resistance, and high temperature resistance. It possesses excellent processability, does not require vulcanization, has relatively low material costs, and is amenable to recycling to save costs. The material TPE substitutes the conventional synthetic rubber and is a new-generation synthetic rubber material.

Advantages of TPE material in the use of sex dolls:

1. Softness or realism of touch (referring to the realism of touch): Softness: The touch of the TPE doll is very soft and elastic. Softness: The softness of the product is now the closest to that of skin. When the body temperature of a human is added to it, its softness becomes even more pronounced, and the skin sensation becomes that of the skin itself.

2. 1. **Affordable Price:** TPE is relatively cheaper than silicone, and TPE molding is easier. So, TPE sex dolls are relatively less expensive than silicone sex dolls. TPE is your most economical option if you just want a sex doll for use!

2. **High Safety Index:** TPE is also environmentally safe and non-toxic, making it safe for direct human touch. TPE is safe for the human body, and there is no need to worry about using it at all!

3. **Excellent Tear Resistance:** TPE has stronger tensile strength and tear resistance than silicone. TPE will therefore not crack naturally and will resist damage!

4. **High Repairability:** TPE is a thermoplastic material that can be repaired with a heat gun with no signs of repair at all (some skills needed, of course)!!!

In addition to its numerous benefits, there are disadvantages associated with TPE sex dolls, which are as follows:

1. **Oil and Dust Attraction:** 1. There is a certain oleophilic property in TPE materials. A brand new sex doll would be slightly oily, which increases the chances for dust and impurities to be attracted to it, thus requiring more frequent cleaning and powdering. Note that the levels of oiliness can be tolerated for all TPE manufacturers, as long as it is not what they call "jelly-like" TPE.

2. Not resistant to high temperatures and strong acids/alkalis: The material of the TPE sex doll is not heat-resistant. If the environment in which the doll will be placed contains high temperatures, such as above 100°C, the TPE sex doll may deform, melt, and thus get damaged. Another thing, the material of the doll is not resistant to high temperatures and strong acids/alkalis.

3. Color and texture: While the material used for TPE can come close to the feel of human skin, it still has some way to go when it comes to the finer details of texture and color compared to, say, the silicone material. Getting the texture and shine of human skin to look extremely realistic is hard, so it’s visually suboptimal for say, a cosmetic item. Splay, take photos!

TPE doll production process:

1. Materials Preparation: TPE pellets, pigment master, and white oil are mixed together. After that, they are poured inside the injection machine barrel and heated to melt them.

2. Injection Molding Process: Vary the factors of the injection molding machine, including the injection pressure parameter, injection speed parameter, holding pressure parameter, and cooling time. Pour the melted TPE material into the mold with the skeleton inside.

3. Trimming and Cleaning: Remove the formed doll from the mold, eliminate the burrs and other scraps, repair the flaws, clean the surface to eliminate the impurities, and powder the surface (you will notice the presence of a thin layer of powder on the doll when you receive the product.

4. Surface Coating: This will involve coating the surface of the face and body of the doll, as well as other details like the eyebrows, lips, surface of the tubes, and nipples.

Silicone

Silicone
Silica gel is a porous material that is obtained through the multi-molecular polymerization of single-molecule silicic acid. It is composed primarily of silicon dioxide with the chemical formula of SiO2·nH2O and has an amorphous structure.

Silica gel at room temperature and pressure has a milky-white or transparent solid granule with no odor. It is chemically stable, thermally stable, strongly rigid, and non-toxic and harmless to health. Due to the profound research done on silica gel, it has various applications, including petrochemicals, catalyst carriers, diesel cleaning, pressure swing adsorption, food, and health nutrition.

Silica gel categories:

It is classified into solid silica gel and liquid silica gel, with liquid silica gel being used in the production of silicone dolls.

It can be categorized into industrial silica gel, food-grade silica gel, and medical silica gel based on application. Silicone dolls will fall under food-grade silica gel.

Benefits of using silica gel as a material for the production of the silicone doll:

1. High visual realism: The silica gel is more realistic to the skin texture. The silica gel skin is smooth with high color saturation and, therefore, it is possible to create more realistic textures of the skin.

2. 3. Easy to clean: The silicone dolls have a smooth surface finish that repels dust particles or dirt. The dolls are easy to clean using water and shower gel. Just a simple wash is required.

4. Heat resistance and long lifespan: The temperature resistance of silicone dolls is as high as 200℃ and is not likely to age or deform even when subjected to high temperatures! Thus, silicone dolls are more durable! Stability is good: It is chemically stable and does not readily react with other materials and has favorable electrical and stability characteristics. It is water-resistant, ozone-resistant, and weather-resistant, and is non-corrosive, physiologically inert, and odorless, and more safe compared to other materials!

Strengths and Weaknesses of Silicone Material in the Use of Sex Dolls:

1. Higher price: The material itself costs higher, the processing process is complex, and the technological requirements for the production environment are strict, making the price of the silicone sex dolls relatively higher, possibly several times higher than that of the TPE material sex dolls.

2. comparatively hard
Silicone is denser so it is harder than TPE and offers a greater feeling of hardness!
(High-school physics says that if an object is solid, the denser it is, the harder and heavier it will be.)

3. 1. **Easily Tearable:** Although silicone possesses some strength, tear-resistance and elasticity are poor when contrasted with TPE. In practical applications, silicone is likely to tear easily when exposed to heavy external pressure or when scratched by a sharp object.

4. **Long Cycle of Customization:** The reason for this is the complex production process; it takes well over a week to deliver the customized silicone dolls if the customer requests additional functions. Ah, the waiting game for doll enthusiasts!

Silicone Doll Production Process:

1. Preparing the Material: Depending on the final color and hardness, combine liquid silicone, coloring agents, and vulcanization agents in a mixture tank using a stirring rod.

2. Mold Injection: Pour the mixed silicone slowly and evenly into the mold with the skeleton.

3. Curing Process: The injected silicone needs to undergo the vulcanization process in order to harden. The vacuum chamber is also used in the degassing process to remove any air pockets.

4. Trimming and Cleaning: After removing the silicone doll from the mold, the mold lines need to be trimmed using fine scissors, which creates repair marks inevitable in this step, and then it is cleaned.

5. Professional Painting: The face and body of the doll, as well as other parts of the doll’s structure consisting of silicone material, are painted with professional silicone oil or silicone paints. The doll is then baked to solidify its structure.

6. Hair and Eyelash Implantation: Implantation of artificial hair is done by inserting it into the head through a one-needle-and-hair technique. Eyebrows and eyelashes can also be hand-inserted.

V. About Realistic Dolls Common questions encountered during actual use of sex dolls!

1. Are oil-producing sex dolls made of TPE material? Is the oil toxic to the human body? When it comes to TPE material sex dolls, oil is expected to be produced. In the matter of oil production, regular TPE sex dolls are not a problem. However, if the oil is excessive, it is possible that the dolls are filled with plenty of oil to make them softer, like jelly-like TPE. I do not recommend purchasing TPE sex dolls that are jelly-like! For first-time oil production, drying them using powder is possible. This oil is called "white oil." It is mineral oil, a material that goes into making lubricants. Skin contact is okay, though the effects of ingestion are not well understood. Thus, ingestion is not advised. ! 2. Could you tell us more about the hardness of silicone? The hardness of silicon is actually easy to perceive with your own senses. Nevertheless, merely labeling it “hard” is an inaccurate description. A better word is “sturdy.” Picture yourself a male friend who loves hugging it—the sensation will be no different from hugging a sex silicon doll! 3. What is platinum silicone? In the industry, there is no such thing as "platinum silicone." The classification of silicone in the industry includes industrial-grade, food-grade, and medical-grade. In relation to the laws and regulations, if the food-grade standards are complied with, then there are no issues. The link connecting the two concepts—silicone and platinum—regards the addition of platinum solution in the process of vulcanization of the said material. This increases the efficiency and effectiveness of said vulcanization. This occurs because there are faster vulcanization techniques too, such as the supply of necessary temperatures in vulcanization and secondary heating vulcanization! This occurs because the rusting of iron follows the same principle. 4. Is TPE material harmful to the human body? But according to the relevant laws and regulations, all goods such as sexual dolls, regardless of the material used, namely silicone or TPE, must meet the criteria for ‘food grade’ products! Thus, from the safety angle, there is absolutely no need to have any qualms whatsoever! However, we must bear in mind the following factor: Irrespective of the product's status regarding its ‘edibility,’ we must not consider the after-effects of its ‘ingestion’! The reason: Nobody investigates ‘ingestion’ of wood!
