Kondisi: bekas, Tahun pembuatan: 2004, nomor mesin/kendaraan: M336, Used Sidel PET Bottling Combiblock 18,000 BPH Technical Specifications & Performance Data This filling monoblock combi integrates stretch blow molding, gravity filling, and capping on a single compact platform for highly efficient PET beverage production. Manufactured by Sidel with precision engineering, the system combines a rotary blow molder, a gravity filler, and an Arol capper to minimize footprint, reduce handling, and boost overall line efficiency. It is an excellent choice for a used filling line or second-hand upgrade in industrial packaging, focused on beverage production in PET containers. Configuration: Combi monoblock for blowing, filling, and capping Manufacturer: Sidel (capper by Arol) Blow molder: Sidel SBO 16 Series 2, rotary, 16 cavities (molds not included) Filler: Sidel ALSIM gravity filler with 63 valves, mechanical valve type Speed: 18,000 BPH on 2L, 23,000 BPH on 0.5L Capper: Arol, 12 heads, pick & place cap feeding Year: 2004 (Blow molder and filler) Rotation: Counterclockwise Hygienic features: Pressurized enclosure with filters at filler inlet Utilities / Options: Air recovery system included; no chiller supplied Hodpey Uvgpjfx Abyon Neck / Closure compatibility: Alaska neck handling; pre-threaded plastic caps including HEXALITE tethered GME30.28 NCB PT 1.00g Containers: Designed for PET bottles Advanced Automation & Control Systems The integrated monoblock design streamlines synchronization between blowing, filling, and capping. The pressurized, filtered filler enclosure enhances hygienic conditions in the filling area and helps maintain product quality. Mechanical gravity valves ensure repeatable, volumetric accuracy for still beverages, while the Arol capper with pick & place feeding delivers consistent torque and precise placement of pre-threaded plastic closures, including tethered closures in line with modern packaging standards. Rapid access to key modules supports routine adjustments and maintenance. Integration Capabilities for Production Lines This combi is designed for seamless integration into a complete packaging line. Upstream, it can interface with preform feeding and heating systems compatible with the Sidel SBO 16 Series 2. Downstream, it connects to conveyors, labelers, inspection devices, and secondary packaging equipment for continuous industrial packaging. Changeovers focus on PET neck compatibility and closure standardization (e.g., GME30.28), ensuring reliable handling in common PET beverage applications. The counterclockwise rotation matches typical plant layouts and enables both in-line and cell-based configurations.
