High-Efficiency Planetary Screw for Plastic Processing Equipment

Nanhaiya's planetary screw 3D shearing system can handle highly filled materials (such as PP with ≥60% calcium carbonate filler and PA with ≥40% glass fiber filler) or high-viscosity elastomers (such as TPU and TPE), reducing plasticizing time by 30%-50% compared to traditional single-screw systems.

The application of planetary screw systems is highly focused on materials that are difficult to handle with traditional single-screw systems, with core applications concentrated in three areas:

1. High-filler plastic processing

Typical products: Calcium carbonate highly filled PP flooring substrate (filler content 50%-70%), glass fiber reinforced PA automotive structural parts (filler content 30%-50%).

Core value: Solving the problem of filler agglomeration and ensuring uniform mechanical properties of products (e.g., tensile strength deviation ≤5%).

2. Elastomer and flexible plastic processing

Typical products: TPR soft rubber toys, TPE automotive sealing strips, PVC flexible pipes (plasticizer content ≥30%).

Core Value: Low-temperature processing reduces plasticizer volatilization, while strong shear ensures uniform elastomer melting, preventing "pitting" on the product surface.

3. Special Material Mixing and Granulation

Typical Products: Conductive plastics with metal powder (e.g., copper powder-filled PE conductive granules), ceramic powder-reinforced plastics (e.g., Al₂O₃-filled PC wear-resistant granules).

Core Value: Three-dimensional mixing ensures uniform powder dispersion (dispersion ≥ 90%), preventing product performance failure due to powder agglomeration.
