SMC PRODUCTION

SMC Sheet Production

Alita operates a self-designed 1.25m wide fully automated SMC production line, combining proprietary high-performance resins with premium glass fibers to provide the most stable prepreg sheets for downstream molding.

Fully Automated Line

Stable Formulation

Multi-layer Composite

PRODUCTION WORKFLOW

SMC Production Workflow

From raw materials to finished products, 6 precision stages ensure the stability of every roll.

Film Laying

Automated laying of high-strength PE film to provide a stable carrier for resin coating.

Resin Coating

Precision metering system applies resin paste evenly, with thickness controlled at ±0.05mm.

Fiber Settlement

Chopping blades cut fiber into 25-50mm segments and settle them evenly onto the resin layer.

Roller Wetting

Multiple groups of wetting rollers apply pressure to force resin into every fiber filament.

Composite Winding

Top and bottom film layers composite with fiber to form a sandwich structure and auto-wind.

Constant Temp Curing

48-72 hours of reaction in a maturation room to reach optimal molding viscosity.

Wetting & Physical Compositing

The core of SMC sheet lies in 'wetting'. Alita's line is equipped with multiple sets of progressive wetting rollers, through precision adjustment of line pressure to force resin paste between fiber filaments.

Precise Fiber Content: Electronic weighing system monitors fiber proportion in real-time (25%-50%).
No Air Inclusion: Negative pressure induction technology ensures no residual bubbles during physical compression.
Customizable: Options for continuous mat reinforcement or local fabric reinforcement.
