Diametro della vite della macchina IBM

Plastic resin is fed from the hopper into the temperature-controlled barrel, where the 55 mm screw with 22:1 L/D ratio plasticises the melt to the precise viscosity required for injection. The molten material is injected at up to 800 kN clamping force into the injection mold, where the preform is shaped with exact neck-thread geometry and parison dimensions. The mandrel core rod remains inside the preform throughout, maintaining concentricity. Once the neck is fully formed and cooled to dimensional stability, the mold opens and the mandrel transfers the preform to the blow station. The complete injection action occurs simultaneously with blowing and ejection at the other stations, ensuring continuous, zero-idle-time operation.

The mandrel carrying the still-warm preform rotates 120 degrees to the blow station, where the blow mold closes at 120 kN clamping force. High-pressure air, supplied at 0.8 to 1.2 MPa, is injected through the mandrel core rod, inflating the preform outward until it conforms precisely to the cavity walls of the blow mold. Cooling water circulates through the mold at 0.3 to 0.4 MPa, rapidly solidifying the bottle shape. Wall thickness uniformity is maintained because the preform temperature profile and parison geometry are already set from the injection stage. Once cooling is complete, the blow mold opens and the mandrel rotates the formed bottle to the stripping station.

At the stripping station, the finished bottles are automatically ejected from the core rods with a 230 mm stripping stroke and released onto the integrated output conveyor. Because injection, blowing, and ejection all occur simultaneously at their respective stations on the rotating turret, the machine operates with a continuous three-action cycle that eliminates idle time and produces zero flash or waste from the bottle neck or base. This one-step injection blow moulding machine process produces no scrap compared with extrusion blow moulding, which typically generates 20 to 40% flash waste. The conveyor output can be connected directly to vision-inspection systems, leak testers, labeling machines, and automatic packaging lines for fully unmanned production.

1. Stock Preparation / Injection Device

The 55 mm screw with 22:1 L/D ratio and four-plus-N barrel heating zones melts and homogenises plastic resin before metering it into the hot runner for injection. An electric-cylinder drive replaces the conventional hydraulic actuator, improving injection speed repeatability and reducing energy consumption by eliminating standby hydraulic losses. This is the primary plasticising and injection unit of the IBM machine.

2. Hot Runner System

The optimised hot runner distributes molten plastic from the injection unit to each mold cavity at uniform temperature and pressure. The ZQ mold hot runner design minimises gram-weight deviation between cavities and ensures that all preforms across the full multi-cavity mold receive identical material volume per shot, which is essential for consistent bottle weight and wall thickness in every injection blow molding machine cycle.

3. Asta centrale (mandrino)

The core rod serves as the inner form around which both the preform and the final bottle are shaped. It transfers the preform from the injection station to the blow station, then to the stripping station, maintaining parison concentricity throughout. The special mandrel structure in ZQ Series machines keeps fast molding cycles and achieves an efficient core cooling effect that reduces cycle time while maintaining dimensional accuracy in the finished bottle.

4. Preforma per bottiglia

The preform is the intermediate hollow form produced at the injection station, with the neck thread already fully formed to final dimensions. Because the neck is shaped under high injection pressure in a precision steel mold, it is 100% accurate and sealed. Unlike stretch blow moulding processes that use pre-manufactured preforms, the one-step IBM process forms the preform in-machine, eliminating a separate preform production and storage step.

5. Injection Mold and Injection Station

The injection mold closes at 800 kN clamping force on a 800 x 400 mm platen, defining the external preform geometry and the complete neck finish. Manufactured from imported S136 steel alloy or 4Cr13 stainless steel, ZQ Series injection molds deliver long service life and resist corrosion from plastic additives. The activity-designed cavity and neck insert system allows cavity and neck components to be changed independently, reducing tooling cost when switching bottle specifications.

6. Blow Station and Blow Mold

The blow station closes the blow mold at 120 kN clamping force around the preform on the mandrel. Compressed air at 0.8 to 1.2 MPa is delivered through the mandrel to inflate the preform to full bottle shape. The blow mold's internal channels circulate cooling water at controlled temperature, solidifying the bottle within the cycle time. Proper blow-mold design ensures uniform wall distribution and a convex, structurally sound bottle base with no weak points.

7. Stripping Station

At the stripping station, the completed, cooled bottles are automatically released from the mandrel with a 230 mm stripping stroke and conveyed to the output line. No manual intervention is required. Because all three stations operate simultaneously, the machine produces finished bottles at every turret rotation, achieving its rated 8.2-second cycle time. The stripping station can be connected directly to downstream automation including visual inspection, leak testing, labeling, and packing equipment.

HDPE

High-density polyethylene is the most widely used resin on the ZQ80, covering pharmaceutical bottles, cleaning product containers, and dairy packaging. HDPE delivers excellent chemical resistance, good rigidity, and food-contact compliance. The ZQ80's 55 mm screw with 22:1 L/D is optimised for HDPE processing across the full viscosity range from injection to blow.

LDPE

Low-density polyethylene is the material of choice for squeeze bottles, eye drop vials, and flexible packaging applications. The ZQ80 processes LDPE at precise injection volumes, ensuring consistent wall thinness at critical squeeze zones. LDPE's flexibility and biocompatibility make it suitable for ophthalmic, nasal, and topical pharmaceutical dispensing applications.

Polipropilene (PP)

PP is widely used for cosmetic bottles, beverage containers, and health care packaging requiring autoclave sterilisation resistance. The ZQ80 handles both homopolymer and copolymer PP grades, including high-transparency random copolymer PP for applications where crystal clarity is a primary packaging specification, such as high-end skincare and nutraceutical bottles.

PVC

Polyvinyl chloride is processed on the ZQ80 for speciality packaging applications where PVC's clarity, rigidity, and barrier properties are required. The machine's precise temperature-zone control prevents PVC degradation by maintaining barrel temperatures within tight tolerances. PVC bottles are used for certain cosmetic, personal care, and non-food chemical packaging applications where material regulatory compliance has been verified by the customer.

PS (Polystyrene)

Standard and high-transparency polystyrene grades are processed on the ZQ80 for lactic acid bacteria drink bottles and specialty cosmetic containers requiring glass-like optical clarity. PS produces brilliant surface finish and is readily decorated with sleeve labels or direct printing. The ZQ80 accommodates both general-purpose PS and high-impact PS blends within its temperature processing window.

ABS

Acrylonitrile butadiene styrene is processed for technical packaging, cosmetic airless dispenser components, and specialty bottles requiring high impact strength combined with a smooth, high-gloss surface. ABS processing on the ZQ80 requires precise barrel temperature management to prevent discolouration, which the multi-zone heating system with independent zone control handles reliably across production shifts.

PU and Specialty Resins

Beyond the standard resins, the ZQ80 can be configured to process EVA, PCTG, environmental corn-based bioplastics, and other speciality materials. These are used for sustainable packaging, medical device packaging, and premium cosmetic applications where material innovation differentiates the brand. Process parameters and screw geometry are customised for each specialty resin upon order confirmation.

Common Injection Blow Molding Problems and Solutions

Reducing Plastic Waste with the Injection Blow Molding Process

Controllo di precisione e flusso

The ZQ80 injection blow molding machine uses servo-controlled injection to deliver precise resin volume to each cavity on every cycle, eliminating the overfill compensation that hydraulic machines typically require. This precise flow control reduces material waste by 20 to 40% compared with traditional methods that rely on overpressure and excess material to ensure complete cavity fill. Operators can fine-tune injection speed, pressure, and hold time independently across the shot, directing material exactly where it is needed in the preform.

Optimised Mold Design for Minimal Scrap

ZQ Series molds use balanced hot runner systems that keep plastic molten and reusable within the runner, eliminating the cold runner sprues and gates that generate solid plastic waste after every shot in cold-runner systems. Gate and runner geometry is computer-optimised to minimise unnecessary material volume in the distribution system, directing the maximum proportion of each shot into the preform cavity. Mold makers review mold-flow simulation data to identify and eliminate any areas where material pools unnecessarily or cools before reaching its intended cavity location.

Closed-Loop Recycling Integration

Although the ZQ80's IBM process is inherently zero-flash at the bottle, any startup purge material or defective bottles from machine warm-up can be collected, granulated, and reintroduced into the production process as a controlled percentage of regrind blend. The closed-loop system processes scrap into uniform particles that are fed back to the hopper without leaving the production floor, reducing raw material costs and supporting sustainability commitments. Real-time monitoring of material properties ensures that recycled content does not compromise dimensional consistency or surface quality in the finished bottles.

Caratteristiche degli stampi automatici della serie ZQ

1. Activity-Designed Cavity and Neck
The injection mold features independently replaceable cavity and neck inserts with a specially designed oil-channel system that maintains stable parison temperature. This modular design allows operators to change cavity geometry or neck thread specification without replacing the entire mold base, significantly reducing tooling cost when launching new bottle sizes or adapting to new closure standards. Stable temperature ensures that tube billet size remains consistent throughout the production run.

2. Struttura in lega di acciaio di alta qualità
ZQ Series molds are manufactured from imported S136 steel alloy or 4Cr13 stainless steel. S136 is a premium mirror-polishable tool steel with excellent corrosion resistance and hardness after heat treatment, ideal for high-clarity pharmaceutical and cosmetic bottle surfaces. 4Cr13 stainless provides superior resistance to corrosive resins and cleaning agents. Both steels significantly extend service life compared with standard tool steels, reducing the annualised tooling cost per million bottles produced.

3. Optimised Hot Runner and Mandrel Cooling
The hot runner system and preform geometry are engineered together to minimise gram-weight deviation and wall-thickness variation from cavity to cavity. The mandrel incorporates a special internal structure that maximises core cooling efficiency, removing heat from the preform interior rapidly enough to maintain the fast molding cycles the ZQ80 is rated for. This integrated thermal design means production speed and quality are not in conflict: the machine runs fast because the thermal management is optimised, not despite it.

4. Accurate Mouth and Thread Geometry
The bottle mouth and thread are formed entirely in the injection mold under full clamping force, producing neck finishes that are 100% accurate in size and achieve a complete seal with the bottle closure. Unlike extrusion blow moulding where the neck is pinched off and trimmed, the IBM process produces a flash-free, burr-free neck on every bottle. This is critical for pharmaceutical child-resistant closures, dropper fitments, and pump dispensers where neck tolerance directly affects closure function.

5. Zero Flash and Zero Waste
No burrs, no parting-line flash, and no waste are produced at the mouth or base of the bottle in the IBM process. This is a fundamental advantage over extrusion blow moulding, which generates 20 to 40% scrap from pinch-off tails that must be granulated and recycled. The ZQ80 eliminates the granulator, the regrind handling system, and the quality risk associated with regrind contamination, giving manufacturers a cleaner, more efficient, and more sustainable production process.

6. Consistent Product Dimensions
Every bottle produced on the ZQ80 exhibits consistent size, weight, parting-line position, and wall thickness because the process is inherently balanced: the same mold, the same servo-controlled injection volume, and the same blow pressure produce the same bottle every cycle. This level of consistency is essential for downstream automated filling, capping, and labeling lines, where dimensional variation from the bottle causes line stoppages and packaging defects that are far more costly than the bottles themselves.

Domande frequenti

Q: What is the injection blow molding machine price for the ZQ80 and what factors affect the final cost?
A: The injection blow molding machine price for the ZQ80 varies based on mold configuration, cavity count, required automation level, and destination market. Machines configured for higher cavitation counts (18 cavities for 30 ml) and integrated visual inspection systems carry higher prices than base configurations. Buyers from markets requiring CE marking or specific electrical standards may also have configuration adjustments. Contact our sales team with your bottle specification, daily production target, and preferred resin to receive a detailed quote including mold cost estimation.

Q: Can the ZQ80 use existing Uniloy UIB120 Model molds without modification?
A: In many cases, existing UIB120 mold components are compatible with the ZQ80 after an engineering assessment. The ZQ80 and UIB120 share a similar 80-ton clamping force class and platen size range. We provide a mold compatibility review service before order confirmation, where your existing mold drawings or dimensional data are evaluated by our engineering team. Minor modifications to mounting features or temperature circuit connections are sometimes required but are typically low cost. Please provide your mold drawings or measurement data to our sales team to initiate a compatibility assessment.

Q: What is the minimum and maximum bottle size the ZQ80 injection blow molding machine can produce?
A: The ZQ80 is designed to produce bottles from 1 ml up to approximately 1,000 ml in a single-stage injection blow moulding process. Maximum bottle diameter is 120 mm and maximum bottle height is 220 mm, with the suitable bottle height range extending to 2,000 mm for certain configurations. For volumes above 250 ml, the mold cavitation count decreases to 5 to 6 cavities for 500 ml and 3 to 4 cavities for 1,000 ml bottles. Applications requiring bottles larger than 1,000 ml should be discussed with our technical team as special tooling configurations may extend this range.

Q: How does the all-electric injection blow molding machine compare with a hydraulic IBM machine in total running cost over five years?
A: The ZQ80's full electric drive typically delivers 30% lower electricity consumption per hour than an equivalent hydraulic machine, which at industrial electricity rates translates to significant annual savings depending on shift patterns and local tariffs. In addition, the elimination of hydraulic oil procurement, disposal, seal replacement, pump maintenance, and related labour removes a recurring cost category entirely. Most manufacturers find that over a five-year operating period, the total cost advantage of the all-electric IBM machine more than compensates for any initial price difference compared with hydraulic alternatives. We can provide a customised five-year cost-of-ownership comparison using your local electricity rates and shift hours upon request.

Q: What automation options are available for the ZQ80 one step injection blow molding machine?
A: The ZQ80 output conveyor can be integrated with a range of downstream automation equipment. Standard options include visual inspection systems that check for foreign particles in the bottle body, insufficient material fill at the bottle mouth, and uneven bottle base geometry; side-leak testers; labeling machines; and automatic packaging or palletizing equipment. With a complete downstream automation package, the line can operate unattended across full production shifts. Optional upstream automation includes auto-loaders for material feeding and mold temperature controllers. Automation scope is specified at the order stage based on production line requirements.

Q: What is the difference between injection blow molding and injection stretch blow molding?
A: Injection blow moulding (IBM) forms the preform by injection moulding and then blows it to final bottle shape without axial stretching. The IBM process is used for HDPE, LDPE, PP, PS, and ABS bottles, typically in the 1 ml to 1,000 ml range, and is the preferred process for pharmaceutical and cosmetic containers where neck accuracy and no flash are paramount. Injection stretch blow moulding (ISBM) adds a mechanical stretch rod that elongates the preform axially before blowing, improving molecular orientation and enabling the production of PET bottles with enhanced barrier properties and strength-to-weight ratios. ISBM is the standard process for PET beverage bottles. The ZQ Series IBM machines are best suited to PP, HDPE, LDPE, PS, and similar resins, not PET.

Q: Is the ZQ80 suitable for pharmaceutical GMP environments and does it comply with hygiene standards?
A: Yes. The ZQ80's bottom-up structural design ensures that no lubricating oil or hydraulic fluid is present above the mold area, eliminating the primary contamination risk associated with hydraulic injection blow moulding machines in pharmaceutical environments. This design is aligned with GMP hygiene requirements for pharmaceutical primary packaging. The machine has been installed in pharmaceutical packaging facilities producing tablet bottles, oral liquid bottles, eye drop vials, and nasal spray containers. Customers should verify their specific regulatory authority requirements, as GMP validation and equipment qualification (IQ/OQ) are the responsibility of the facility operator.

Q: How long does commissioning take and what on-site support is provided?
A: On-site installation and commissioning of the ZQ80 typically requires three to five working days depending on factory readiness, automation scope, and mold configuration. Ever-Power provides experienced senior engineers for installation, equipment commissioning, production run-off, and comprehensive operator training covering machine operation, mold processing parameters, and routine maintenance procedures. After commissioning, our after-sales service hotline operates 24 hours a day, seven days a week. Preventive maintenance reminders and an adequate spare parts inventory system are also provided to minimise unplanned downtime during commercial production.

Q: What compressed air specifications are required for the ZQ80 injection blow molding machine?
A: The ZQ80 requires compressed air at a minimum pressure of 0.8 MPa and a maximum of 1.2 MPa, with a capacity of 0.8 m3 per minute for standard bottle production. Clean, dry, oil-free compressed air is required to prevent contamination of the blow air path and to ensure consistent blow pressure from cycle to cycle. We recommend a dedicated screw air compressor with an air dryer and filtration system for pharmaceutical and food-contact packaging applications. For high-cavity-count molds or rapid cycle operations, compressed air volume requirements should be reviewed with our technical team during the pre-order specification phase.

Q: Can the ZQ80 produce LED bulb cover and other transparent technical parts?
A: The ZQ80 is capable of producing transparent PS or PP LED bulb covers and similar technical hollow parts that require high optical clarity and precise geometry. The controlled preform temperature profile and uniform wall-thickness capability of the IBM process produce parts with superior optical uniformity compared with extrusion blow moulding. Mold design for LED bulb covers requires careful venting and cooling circuit design to achieve the required surface clarity. Our mold design team can assist with optimising tooling for LED cover applications. Material selection, typically high-transparency PP or PS, is confirmed at the tooling design stage.
