Why choose SW plastic extrusion propfiles
When your project faces special environmental challenges, stringent certification requirements or innovative functional ideas, Shuowei design team will use the combined capabilities of material science + precision manufacturing to deliver custom plastic extrusion profiles solutions that exceed expectations.

Multi-cavity insulation/noise reduction topology optimization:
View the case of energy-saving window frames (see Australian project NatHERS 7-star certification for details)

3-layer co-extrusion (hard/soft/functional coating): View the case of medical antibacterial PVC skirting board (antibacterial rate 99.8%)

-50℃~150℃ weathering simulation technology: view the case of Saudi photovoltaic support (15 years of sand erosion resistance)

Glass fiber/carbon fiber reinforcement solution (GF30/CF50): view the case of Electric vehicle battery box (40% weight reduction)
Precise custom plastic extrusion profiles process
Thanks to our excellent management system, all the custom plastic extrusion processes are controllable.
- Get your “Profile Design Requirements List” for free Issue a feasibility report within
- 72 hours (including material selection/cost analysis/compliance path)


- 3D modeling: SolidWorks/AutoCAD precise output (±0.02mm tolerance)
- CAE simulation: ANSYS structural stress analysis, mold flow optimization (reduce mold trials by 50%)
- Rapid prototyping: 3-7 days to deliver functional samples (support on-site testing and matching)
- Own mold workshop: CNC machining center achieves ±5μ precision die head
- Solve the problem of “weld line weak area” (automotive sealing strip tensile strength ↑30%)
- Eliminate “profile bending rebound” (building curtain wall straightness reaches 0.1mm/m)


- First full-size laser scanning comparison (100+ inspection points)
- Small batch trial production → Full inspection data meets standards → Release large batch orders
