2026-03-04

The curved-arm blow molding machine, with its unique mechanical structure and highly efficient, stable performance, finds extensive application in the production of hollow plastic products. It is particularly suited for high-volume, high-speed automated production scenarios. Its key advantages include a compact structure, rapid response speed, low energy consumption, and the ability to achieve high-precision mold opening and closing control, significantly enhancing production efficiency and product consistency.

I. High Operating Speed and Production Efficiency
The curved-arm mechanism employs servo-driven linkage transmission for rapid mold opening/closing response, completing a cycle within 1 second to meet high-speed blow molding demands.
When paired with dual-station or multi-nozzle configurations, it enables continuous extrusion and synchronized inflation, substantially increasing output per unit time.
For instance, the SLBK series curved-arm blow molding machine achieves an hourly output of 4,200 beach balls, making it ideal for large-scale order fulfillment.
II. Significant Energy Savings
Compared to traditional hydraulic models, the articulated arm structure optimizes force transmission paths to reduce energy loss;
Precise servo motor control of all motion axes enables demand-based power supply, achieving overall energy savings exceeding 30%;
Hydraulic systems are reserved for critical actions (e.g., mold clamping, blowing), while electric servos handle the rest, minimizing oil temperature rise and cooling load.
III. High Control Precision and Product Stability
The PLC + HMI control system enables fully digital parameter settings and real-time monitoring;
Mold opening/closing position repeatability reaches ±0.05mm, ensuring tight mold closure and reducing flash and scrap rates;
Multi-stage wall thickness control ensures uniform blank ejection, enhancing container compressive strength and surface quality.
IV. Compact Structure, Easy Maintenance
Highly integrated curved arm mechanism occupies minimal space, ideal for compact workshop layouts in SMEs;
Fewer transmission components reduce failure points, simplifying routine lubrication and inspections;
Key components like guide rails and bearings use high-wear-resistant materials for extended lifespan and low maintenance costs.
V. Strong Adaptability, Wide Application Range
