Three-Station ISBM Working Process
Understanding the precise sequence of operations reveals the technological sophistication behind one-step injection stretch blow molding
Station 1: Injection Molding
The process begins as virgin or recycled polymer pellets enter the plasticizing unit, where they undergo controlled heating within the extruder barrel. The reciprocating screw mechanism with diameters ranging from 40mm to 55mm simultaneously melts the material and builds injection pressure. Once the required shot volume accumulates at the screw tip, the servo-controlled injection system drives the molten polymer through the hot runner manifold into the preform cavities. The preform design incorporates the final bottle's neck finish with complete threading, while the body portion contains excess material that will be stretched and expanded during blow molding.
Mold cooling begins immediately after injection, with chilled water at 0.4-0.6 Mpa pressure circulating through precisely machined cooling channels. The 50KN injection clamping force ensures proper cavity sealing while the preform solidifies sufficiently to maintain dimensional stability when ejected from the injection mold, yet retains enough core temperature to facilitate stretching without requiring external reheating. This thermal balance represents one of the critical advantages of single-step processing.
Station 2: Thermal Conditioning
After the turret indexes to position two, the freshly molded preform enters the conditioning station where thermal profiling occurs. This intermediate step addresses the reality that optimal injection molding temperatures differ from ideal stretch blow molding temperatures. The conditioning station employs carefully calibrated systems to adjust the preform's temperature gradient. The neck region, already formed to final dimensions, must remain relatively cool to preserve threading accuracy and prevent deformation. Meanwhile, the body section requires precise heating to achieve the temperature window where the polymer exhibits optimal stretch characteristics.
For PET applications, this typically means bringing the preform body temperature to the appropriate range where the material exhibits optimal flow and stretching properties. The conditioning duration must be precisely synchronized with the overall machine cycle to maintain production efficiency while ensuring every preform reaches the blow station at optimal temperature, ready for the final transformation into finished bottles.
Station 3: Stretch Blow Molding
At the final station, the conditioned preform undergoes transformation into the finished bottle through synchronized mechanical stretching and pneumatic expansion. The preform transfers into the blow mold cavity, which has been precision-machined to the exact bottle geometry. A servo-controlled stretch rod extends downward into the preform, mechanically elongating the material in the axial direction. This longitudinal stretching induces molecular orientation that significantly enhances the final bottle's mechanical properties, particularly impact strength and barrier characteristics.
Simultaneously with stretch rod extension, high-pressure air at 2.0-3.5 Mpa enters through the preform neck. The blow pressure forces the stretched material outward against the cooled mold surfaces. This radial expansion creates circumferential molecular orientation, resulting in biaxial orientation that provides optimal strength-to-weight ratios. The blow mold's integrated cooling system rapidly quenches the expanded material, freezing the molecular structure and setting the final bottle shape. The 100KN blowing clamping force ensures dimensional accuracy throughout the process. Once cooling is complete, the mold opens and the finished bottle is automatically ejected, ready for downstream operations such as filling, labeling, and packaging.
How to Manufacture Bottles Using ISBM Technology
Operating the EP-HGY50-V3-EV requires understanding both the machine capabilities and the material science principles governing thermoplastic bottle formation. The following comprehensive guide walks through the complete bottle manufacturing process from raw material preparation through quality control and finished product discharge.
Material Preparation and Loading
Begin by selecting appropriate grade polymer pellets suited to your application requirements. For beverage bottles, food-grade PET with an intrinsic viscosity around 0.80 dL/g typically provides the best balance of processability and final properties. Ensure the material has been properly dried to moisture content below 0.004 percent, as excess moisture causes hydrolytic degradation during processing, leading to reduced molecular weight and compromised mechanical properties. The material hopper feeding system maintains consistent flow into the extruder barrel, where controlled heating zones gradually raise the polymer temperature.
Parameter Configuration and Recipe Setup
Access the touchscreen control interface to configure all process parameters for your specific bottle design. Critical settings include barrel temperature profiles typically ranging from 260-290 degrees Celsius across the five heating zones, injection speed curves that balance cavity filling time against flow-induced stresses, holding pressure duration and magnitude to compensate for material shrinkage, and mold temperatures optimized for the desired cooling rate. The servo control system allows independent adjustment of each parameter with precision unavailable in conventional machines. Store these settings as a recipe for future production runs of the same bottle design, enabling changeovers to be completed within minutes rather than hours.
Production Start-up and Optimization
Initiate the heating sequence and allow sufficient time for all components to reach thermal equilibrium, typically thirty to forty-five minutes depending on ambient conditions. Once temperatures stabilize, begin a purging cycle to clear any degraded material from previous production and verify proper material flow. Execute several test cycles in semi-automatic mode, carefully examining each bottle for defects such as incomplete filling, surface blemishes, dimensional variations, or optical irregularities. Use these initial samples to fine-tune parameters, making small adjustments to injection speed, stretch rod timing, or blow pressure as needed. Modern machines provide real-time process monitoring that displays injection pressure curves, cavity temperature evolution, and cycle timing, enabling data-driven optimization rather than trial-and-error approaches.
Continuous Production Monitoring
During sustained production, maintain vigilant oversight of key performance indicators. Monitor cycle time consistency, as variations often indicate developing mechanical or thermal issues before they cause quality problems. Track reject rates and investigate any upward trends immediately. Verify dimensional stability through periodic sampling and measurement of critical features like wall thickness distribution, base concentricity, and thread engagement. The machine's diagnostic systems continuously monitor servo motor currents, hydraulic pressures, and temperature sensor readings, providing early warning of component wear or system malfunctions. Implement a regular sampling schedule, typically every thirty minutes during stable production, with samples tested for burst strength, top load compression, and drop impact resistance to ensure ongoing compliance with specifications.
Quality Control and Validation
Establish comprehensive quality protocols encompassing both in-process checks and finished product testing. Visual inspection should catch obvious defects like flash, sink marks, or surface contamination. Dimensional verification using calibrated gauges confirms bottles meet drawing specifications. Mechanical testing validates that bottles possess adequate strength for their intended application, with particular attention to failure modes relevant to end-use conditions. For pharmaceutical or food contact applications, additional testing may verify material compliance with regulatory requirements, absence of extractable or leachable compounds, and maintenance of barrier properties. Documentation of all test results creates the quality record necessary for traceability and continuous improvement initiatives.

Frequently Asked Questions
What are the main advantages of one-step ISBM compared to two-step blow molding?
One-step ISBM integrates preform injection and bottle blowing in a single machine, eliminating the need for separate preform production, storage, and reheating. This reduces energy consumption by approximately thirty to forty percent, decreases production cycle time, minimizes material handling, and reduces facility space requirements. The integrated process also ensures optimal preform temperature control without the degradation risks associated with reheating in two-step systems.
Can this machine produce bottles with different neck finishes and thread designs?
Yes, the machine accommodates various neck finish designs through mold changes. Common thread specifications including 28mm, 38mm, and custom designs can be produced. The neck diameter range from 17mm to 60mm supports applications from small pharmaceutical bottles to wide-mouth containers. Changing neck finish requires mold replacement, which can typically be completed within two hours using the quick-change mold mounting system.
What is the typical production output and how does cavity number affect it?
Production output varies with cavity configuration and bottle size. For mid-range bottles around 500ml, a 4-cavity mold typically produces 1,800-2,200 bottles per hour depending on cycle time. Smaller bottles allow higher cavity counts and faster cycles, potentially reaching 2,400+ bottles per hour with 6-cavity configurations. Larger bottles may require 1-2 cavity molds with proportionally lower output rates but still maintaining efficient production for their size category.
What maintenance requirements should be expected with this equipment?
Regular maintenance includes daily cleaning of mold surfaces and blow pins, weekly inspection of servo motor operation and belt tensions, monthly lubrication of guide rails and mechanical components, and quarterly replacement of filter elements. The servo-driven system requires less maintenance than hydraulic equipment, with no hydraulic oil changes needed. Annual maintenance should include detailed inspection of screw and barrel wear, calibration verification of temperature controllers and pressure sensors, and examination of electrical connections.
Can recycled PET material be used in this machine?
The machine can process recycled PET content, though the percentage depends on application requirements and material quality. For non-food contact applications, up to fifty percent post-consumer recycled content is often feasible. Food-contact applications typically limit recycled content to FDA-approved post-consumer recycled grades. Recycled material must be thoroughly dried and may require adjusted processing temperatures. Some testing is recommended to optimize parameters when introducing recycled content into your production.
What utilities are required to operate the machine?
The machine requires three-phase electrical power at 370-400V with total connected load of 68KW. Compressed air supply at 2.0-3.5 Mpa is necessary for blow molding operations, typically requiring a compressor capacity of 2-3 cubic meters per minute. Cooling water at 0.4-0.6 Mpa pressure with temperature around 15-20 degrees Celsius is essential for mold cooling and barrel temperature control. Adequate ventilation should be provided to remove heat generated during operation.
How long does operator training typically take?
Basic operational competency can be achieved in three to five days of intensive training for operators with prior plastics processing experience. Training covers machine setup, parameter adjustment, routine troubleshooting, and quality inspection procedures.
