Core features
Lightweight design
The hollow structure formed by the blow molding process greatly reduces the weight (30%~50% lighter than the metal frame) while ensuring strength, making it easy to move and install.
High structural strength
Through the internal reinforcement rib design, it can withstand a large load (usually ≥150kg), suitable for frequent use scenarios.
Integrated molding
Reduce splicing parts, reduce the risk of cracking, and improve durability (lifespan can reach 8~10 years).
Rust and corrosion resistance
Polymer materials (such as HDPE, PP) are resistant to moisture and sweat stains and are suitable for long-term use.
Process advantages
- Cost-effectiveness: mold costs are lower than metal stamping, suitable for medium and large-scale production (unit cost is reduced by 20%~40%).
- Flexible design: curved surfaces and special-shaped structures can be made to adapt to ergonomic curves (such as lumbar support and neck curvature).
- Environmental protection: materials are recyclable, and the scrap rate during production is less than 5%.
Typical application scenarios
Home massage chairs:
Advantages: Quiet (no metal friction sound), warm touch (not cold in winter).
Case: The backrest frame of the zero-gravity massage chair needs to be adjusted at multiple angles with the motor.
Commercial shared massage equipment (such as airports and shopping malls):
Advantages: Resistant to frequent use, easy to clean and disinfect, and low maintenance cost.
Rehabilitation medical chairs:
Advantages: No sharp edges, high safety; customizable holes to adapt to rehabilitation equipment.

Market trends
- Material upgrade: Carbon fiber reinforced plastic (CFRP) begins to be used in high-end models, reducing weight by 15% while increasing strength.
- Intelligent integration: The skeleton reserves sensor wiring grooves, which are compatible with pressure detection and posture reminder functions.
Through the continuous optimization of the massage chair blow molding machine process, this type of skeleton is gradually replacing some metal structures, especially in the field of user experience and cost control. It is recommended to provide usage scenario drawings when selecting specific models, and the supplier will simulate the stress distribution and customize the solution.
