Sex dolls have become a popular sex toy due to their high simulation and excellent touch. Its production process is a combination of industry and art. We will tell you how doll factories use TPE or silicone materials to make highly humanoid sex dolls.
Overview
Making a new sex doll begins with the body design, then goes through the following steps: mold making, skeleton creation, pouring mold, demolding, trimming, makeup, and packaging.
- Designing the doll: The designer will find suitable models and adult celebrities to take measurements of their body measurements, such as measurements and height, and then finalize the design through 3D modeling.
- Making the mold: The mold is made for later mass production. The head and body molds are separate, allowing for easy replacement of the head.
- Making the skeleton: The doll's skeleton is typically made of stainless steel with movable joints. The skeleton will be secured within the mold.
- Injection molding: TPE or silicone material is mixed with other pigments and formulas, stirred thoroughly, then heated to around 200°C and poured into the mold.
- Cooling and demolding: The poured mold is allowed to cool for several hours before opening and removing the doll.
- Finishing details and makeup: Newly made dolls will have rough edges that need to be manually trimmed, and makeup is then applied to the head. For silicone dolls, additional steps such as hair implantation and eyelash implantation may also be required.
- Packing: After the sex doll is completed, it will be packaged in corrugated cardboard boxes for shipment.
This is a general overview of the factory production process for sex dolls. Of course, depending on customization options, the materials and steps may vary.
Designing the doll

- Ethnicity: Asian sex dolls; Caucasian sex dolls; African sex dolls; Latino sex dolls.

Some sex factories also design sex dolls based on popular characters or personas, such as collaborating with adult stars to create replicas or using characters from anime and film. For example, you may find Tifa sex doll, Jill sex doll and Harley Quinn sex doll online.
Making the mold
The 3D scanner can collect the body data of a real model, and the sculptor will make the sex doll mold according to this. The molds of head of body are made separately.
Making the skeleton
Almost all sex dolls have built-in skeletons and joints, which can better fix the doll's body and keep it in a specific sex position. Some high-end dolls also have a skeleton with finger joints and clavicle structure to achieve more flexible posture control.
Injection molding
- Fix the doll's skeleton in the mold.
- According to the required color and hardness, mix the silicone/TPE with pigments, additives, etc.
- Inject the mixed silicone/TPE into the prepared mold, making sure the silicone fills every detail of the mold.
Cooling and demolding
The poured mold needs to be placed in clean cold water or cool room for several hours, then the TPE or silicone material will solidify and take shape, and we can take the sex doll out of the mold.

Finishing details and makeup
- The newly made dolls may have thread marks and glue overflow. The staff will further refine the details.
- Next, the staff will install fingernails and toenails for the doll and spray the body paint.
- Finally, the makeup artist will make up the doll's head and implant hairs.

Packaging
First, the staff will put air bags, towels or foam around the cardboard box, and then fix the doll in the middle area. The head is usually placed between the legs to prevent damage during transportation.

Final Words
The process of making a sex doll in factory is completely different from making homemade sex doll. The factory has professional equipment and makeup artists, and you can add custom features like heating, sound, and vaginal suction for your doll. Are you ready to buy your sex doll?
