Manufacturing

Realistic sex dolls are produced through a nine-stage process: specification definition, steel or resin mold design, silicone casting with vacuum degassing, controlled curing, demolding, hand-finishing, skeleton assembly, function testing and AQL inspection. BeLove Tech runs this process in-house across 12 production lines in Dongguan, China.

Nine-stage production process

Stage	Process	Key control
1. Specification	Height, weight, composition, skin tone, joints agreed	Drawing approval
2. Mold design	Steel or resin mold designed from spec	Surface finish grade
3. Mold production	CNC machining and polishing	Dimensional accuracy
4. Material prep	Silicone or TPE mixed 1:1 by weight	Precision scale, traceability
5. Casting	Vacuum pouring, 2–3 degassing cycles	Void and bubble removal
6. Curing	4–24 hours controlled temperature	Temp and humidity logging
7. Demolding	Careful release from mold	Seam integrity check
8. Finishing	Skin detail, seam blending, matte or satin	Cosmetic inspection
9. Assembly and QC	Skeleton insertion, function test, AQL	24-point inspection

Why in-house mold development matters

Aspect	In-house	Outsourced
Cycle time	Direct control, faster sampling	Third-party queue adds weeks
Surface finish	Adjustable on site	Requires new vendor cycle
Detail resolution	Immediate iteration	Slow feedback loop
IP protection	Designs remain in-house	Shared with vendor

In-house tooling is the single largest contributor to both sample turnaround and repeat-order cost.

Seam construction

Construction	Description	Result
Seamless	Single-piece molding where geometry allows	No visible parting line
Molded	Multi-piece mold with parting lines	Blended at finishing
Modular	Torso, head and hand as separate components	Standardized, replaceable

Skeleton types

Skeleton	Construction	Application
Metal skeleton	Internal steel frame with joints and wiring	Full-body dolls, highest articulation
Wire frame	Embedded wire armature	Torso and lower tiers
Partial frame	Localized armature	Entry products

Quality checkpoints

Checkpoint	Verified	Reject trigger
Material incoming	Material grade, batch hardness	Grade substitution, hardness out of ±2
Mold setup	Mold condition, venting	Worn mold, air entrapment
First article	Dimensional and cosmetic	Deviation from approved spec
Post-casting	Voids, bubbles, incomplete fill	Visible voids
Final	Function, cosmetic AQL, packaging	Articulation or appearance failure

Frequently asked questions

How long does it take to produce a custom sex doll?

With existing molds, production runs 5 weeks. New mold development adds 4 to 6 weeks depending on complexity.

Do you produce both TPE and silicone?

Yes. Both materials are produced in-house, so material selection does not affect lead time.

Is mold tooling produced in-house?

Yes. In-house tooling shortens the sampling cycle and gives direct control over surface finish and detail reproduction.

What quality standard is manufacturing conducted under?

All production is carried out under an ISO 9001:2015 quality management system, with control applied from incoming material inspection to pre-shipment verification.
