Aoki Injection Stretch Blow Molding Machinery and Systems (Japan)

High-speed injection stretch blow molding machines Aoki AL Series (AL-1000, AL-500, AL-250)

The high-speed three-station Aoki AL series is engineered for mass production of pharmaceutical vials, cosmetic bottles, droppers and precision containers from PET, PP, PC and bio-resins.

Its compact architecture integrates preform injection, temperature conditioning and stretch-blow molding into a unified single-stage Direct Heatcon cycle eliminating secondary reheat ovens.

Advanced servo-driven indexing tables and rigid clamping units deliver exceptional dimensional repeatability with dry cycle times starting from 3.8 seconds. Systems are fully compliant with cleanroom GMP pharmaceutical manufacturing standards.

Selection guide: Selection criteria: container volume (5 to 1000 ml), mold cavitation (2 to 16 cavities), polymer grade and target hourly throughput.

Universal injection stretch blow molding machines Aoki SBIII Direct Heatcon Series

The flagship Aoki SBIII line (including SBIII-1000LL, SBIII-500LL-75, SBIII-250-50 and SBIII-100LL-50) represents the global benchmark for single-stage molding of wide-mouth jars, oval bottles and large containers up to 10 liters capacity.

Utilizing proprietary Direct Heatcon direct heat transfer, SBIII systems achieve superior optical clarity, precise neck orientation and wall thickness control while slashing overall energy consumption by up to 40% compared to conventional two-step blow molding.

Open platen access facilitates ultra-fast mold changeovers.

Selection guide: Selection criteria: neck finish diameter, container height, body diameter, injection clamping force and shot volume.

Aoki bimetallic plasticizing units and barrel-screw assemblies for advanced polymers

Genuine Aoki plasticizing assemblies are specifically configured for stable processing of heat-sensitive and abrasive resins including virgin PET, food-grade recycled rPET flakes, PP, Tritan, PC and bio-based PLA.

Centrifugally cast bimetallic barrels lined with nickel-tungsten carbide alloys paired with specialized barrier mixing screws ensure ultra-uniform melt homogeneity without resin thermal degradation, intrinsic viscosity drop or nozzle drool across extended multi-shift production runs.

Superior wear resistance extends service lifetimes significantly when handling heavily filled compounds.

Selection guide: Selection criteria: screw diameter (32 to 120 mm), L/D ratio, polymer type and maximum barrel operating temperature.

Complete ISBM tooling sets and hot runner mold systems Aoki

Aoki turnkey ISBM mold tooling sets encompass injection preform molds, valve-gated hot runner manifolds, temperature conditioning blocks and multi-cavity blow molds.

Manufactured from premium Japanese tool steels with mirror optical cavity polishing (Ra < 0.05 μm) and hard chromium plating, these tooling systems guarantee rapid changeover on machine indexing platens and micrometer-precise alignment of stretch rods and neck inserts, eliminating wall thickness variations.

Conformal cooling channels accelerate mold cooling and boost throughput by up to 20%.

Selection guide: Selection criteria: container technical drawing, 3D CAD model, cavitation (1 to 24 cavities), neck finish standard and Aoki machine model.

Aoki energy-saving servo-hydraulic power units and valve manifolds

Aoki servo-hydraulic power units feature energy-saving AC servomotors coupled with precision Japanese axial piston pumps (Daikin, Yuken, Nachi) that deliver hydraulic fluid strictly matching real-time clamping or injection demands.

High-response proportional pressure and flow valves guarantee smooth platen transitions, zero hydraulic shock and whisper-quiet operation under peak system pressures up to 210 bar.

Selection guide: Selection criteria: servo motor rating, pump displacement, hydraulic pressure rating and interface bus protocol.

High-pressure blow molding pneumatic systems (up to 40 bar) and valve blocks Aoki

Aoki high-pressure blow air control assemblies manage precision two-stage air delivery: low-pressure pre-blow (6 to 10 bar) for initial preform expansion and final high-pressure blow (up to 40 bar) for crisp definition of container bases, ribs and logos.

Ultra-fast electropneumatic valves with response times under 15 ms maintain consistent bottle sidewall distribution across multi-cavity tooling without pressure fluctuation.

Selection guide: Selection criteria: blow pressure rating (25 to 40 bar), airflow rate, valve switching time and Air Recovery integration.

Multi-zone ceramic band heaters, manifold heating elements and PID controllers Aoki

Aoki multi-zone ceramic and mica band heating elements maintain tight temperature stability across injection barrels and hot runner nozzles within ±0.5 °C.

Encased in corrosion-resistant stainless steel housings with basalt insulation blankets, they drastically reduce ambient heat radiation, protecting sensitive machine electronics and reducing overall factory energy loads.

Selection guide: Selection criteria: internal diameter, band width, wattage rating, operating voltage (220/380V) and thermocouple type.

Industrial Aoki Machine Controller (AMC) automation systems and touchscreen HMI panels

The dedicated Aoki Machine Controller (AMC) CNC architecture performs comprehensive real-time coordination of all process variables: injection velocity, packing pressure profiles, multi-zone hot runner temperatures, servo stretch trajectories and cooling times.

Its intuitive touchscreen interface with comprehensive mold recipe storage accelerates product changeovers and slashes downtime.

Selection guide: Selection criteria: AMC controller generation, HMI screen size, network bus protocols (Ethernet, CANopen) and I/O module configuration.
