Technische Spezifikationen

Injection Blow Molding Machine Components

1. Stock Preparation / Injection Device
The stock preparation and injection device is the primary plasticizing unit of the ZQ135. It consists of a precision 70mm screw with a 22:1 L/D ratio, multiple barrel heating zones, and an electric cylinder-driven injection unit. This system melts, homogenizes, and injects plastic resin into the mold cavity at controlled pressure and temperature.

2. Hot Runner System
The optimized hot runner system maintains consistent melt temperature as molten plastic flows from the injection unit to each mold cavity. This ensures uniform material distribution, minimizes gram weight deviation, and reduces material waste. The precision-controlled thermal management of the hot runner is critical for producing bottles with consistent quality and appearance.

3. Core Rod
Core rods serve as the internal mandrels around which the preform is injection molded. They feature a specially engineered structure with internal cooling channels that provide rapid and uniform core cooling during production. The core rod design directly influences cycle speed, preform concentricity, wall thickness uniformity, and the overall quality of the finished bottle product.

4. Bottle Preform
The bottle preform is the intermediate product formed at the injection station. It is a precisely shaped tube of plastic with a fully formed neck finish and thread. The preform wall thickness, weight, and temperature are carefully controlled before transfer to the blow station, where it will be inflated into the final bottle shape inside the blow mold cavity.

5. Injection Mold
The injection mold features activity-designed cavities and neck inserts with specially engineered oil channels that can be changed conveniently for different products. Constructed from imported S136 steel alloy or 4Cr13 stainless steel, the injection mold delivers exceptional durability and precision. The mold determines the preform shape, neck geometry, and thread dimensions with extreme accuracy.

6. Injection Station
The injection station is the first of three rotary positions where the plastic melt is injected around the core rods to form accurate preforms. It integrates the injection mold, clamping mechanism, and heating system. The 1350KN clamping force of the injection system ensures stable mold closure and precise material filling during each injection cycle without flash or overflow.

7. Blow Station
The blow station is the second rotary position where compressed air (0.7 to 1.2 MPa) inflates the heated preform inside the blow mold to form the final bottle shape. Precise air pressure control ensures uniform wall thickness and accurate bottle contours. The cooling system within the blow mold solidifies the bottle before transfer to the stripping station for finished product ejection.

8. Blow Mold
The blow mold defines the final shape, size, and surface texture of the finished bottle. It features precision-machined cavity surfaces with integrated cooling channels for rapid and uniform bottle solidification. The 200KN blowing clamping force ensures the mold halves remain securely closed during the inflation process, producing bottles with consistent dimensions and flawless surface quality.

9. Stripping Station
The stripping station is the third and final rotary position where finished bottles are automatically ejected from the cooled core rods. The 280mm stripping stroke ensures clean and complete removal of bottles ranging from small vials to larger containers. Ejected bottles are transferred directly to the output conveyor for inspection, labeling, or packaging without any manual handling required.

Funktionsprinzip

The ZQ135 injection blow moulding machine operates on a highly efficient three-station rotary process that enables injection, blowing, and stripping to occur simultaneously. This concurrent operation is the foundation of the machine's exceptional productivity and minimal waste generation, making it one of the most efficient machines in its class on the market today.

1. Vorformlingsinjektion
During the injection station, molten plastic material is precisely injected into the mold cavity around the core rod, forming an accurate preform with a perfectly molded bottle neck and thread finish. The injection process ensures complete control over material distribution, wall thickness, and neck geometry. After the preform reaches the proper temperature and solidification point, the mold opens and the mandrel carrying the shaped preform is transferred to the blow molding station via the rotary table mechanism.

2. Blasformen
At the blow station, compressed air is channeled through the mandrel to inflate the heated preform inside the bottle mold cavity. The expanding plastic material conforms precisely to the mold contour, forming the final bottle shape. The bottle shape and mold design determine the number of cavities per cycle. After sufficient cooling and solidification within the mold, the finished bottle retains its dimensional accuracy. The mold then opens and the rotary table transfers the mandrel and completed bottle to the stripping station.

3. Stripping and Ejection
At the stripping station, the finished bottles are automatically ejected from the cooled core rods and conveyed to the packaging line. The three actions of injection, blowing, and ejection work simultaneously at their respective stations on each rotation cycle, which is what makes this one step injection blow molding machine highly efficient with virtually zero production waste. Because the bottle neck is pre-formed during injection, there are no burrs, no flash trimming, and no secondary finishing required, resulting in bottles ready for immediate use.

Injection Blow Molding vs. Extrusion Blow Molding

Both injection blow molding and extrusion blow molding are widely used processes for manufacturing hollow plastic containers, but they form the starting shape in completely different ways. Injection blow molding begins from an injection-molded preform, where molten plastic is injected around a core rod to create a precise preform with an accurately formed neck finish. Extrusion blow molding, on the other hand, starts from an extruded parison, a hollow tube of molten plastic that is extruded downward from a die head. This fundamental difference in starting form affects neck precision, wall thickness control, trimming waste, mold structure, material behavior, cycle stability, and the type of bottle each process can produce efficiently.

How Injection Blow Molding (IBM) Works

Injektion: Molten plastic is injected around a core rod to form a precise preform with an accurately finished neck and thread.

Blasen: The preform is transferred to the blow station and inflated with compressed air inside the bottle mold to form the final container shape.

Strippen: The finished bottle is ejected from the core rod without any trimming or flash removal required, resulting in a clean finished product.

How Extrusion Blow Molding (EBM) Works

Extrusion: Molten plastic is extruded downward as a hollow tube called a parison from the die head.

Klemmung: The mold closes around the parison and pinches off excess material at the top and bottom.

Blowing and Trimming: Compressed air forms the bottle shape, then flash waste must be trimmed and recycled after cooling.

IBM controls the neck through injection molding, providing extremely high thread accuracy and sealing reliability. EBM forms the bottle from a parison and normally generates trimming waste that requires secondary processing. The IBM injection blow molding machine structure is built around core rods and station transfer, while EBM machine structure is built around extrusion, parison control, and mold clamping.

IBM vs EBM: Which Blow Molding Process Should You Choose?

Choose injection blow molding when you need: Small or medium precision bottles with accurate threaded necks; pharmaceutical, medical, cosmetic, laboratory, or high-value packaging; low flash waste and cleaner production without secondary trimming; stable dimensions, repeatable wall thickness, and reliable sealing performance.

Choose extrusion blow molding when you need: Large bottles, jerry cans, drums, tanks, or irregular hollow parts; lower tooling cost for less precision-critical packaging; large container flexibility and wider product geometry options; applications where trimming flash is acceptable in the process.

This high-strength steel selection significantly increases the service life of the mold tooling, reducing long-term replacement costs and ensuring consistent product quality over millions of molding cycles.

3. Optimized Hot Runner and Preform System
The optimized hot runner system and bottle preform design work together to minimize gram weight deviation and wall thickness variation. The specially engineered mandrel structure maintains fast molding cycles while providing excellent core cooling performance, ensuring uniform preform quality that translates directly to consistent, high-quality finished bottles throughout extended production campaigns.

4. Precision Neck and Thread Accuracy
The mouth and thread dimensions produced by the ZQ Series mould are extremely accurate in size, achieving 100% sealed closure performance. This level of precision is critical for pharmaceutical and food packaging applications where tamper-evident sealing and leak-proof closure are mandatory requirements for regulatory compliance and consumer safety in end-market distribution.

5. Zero Burr and Zero Waste Finish
There are absolutely no burrs and no waste material on the mouth or bottom of the finished bottle. Unlike extrusion blow molding, the injection blow molding process eliminates flash entirely, so no secondary trimming or finishing operations are required. This clean production advantage reduces labor costs, eliminates regrind processing, and ensures that every bottle is ready for immediate filling and packaging.

6. Dimensional and Weight Consistency
The product size, weight, mold parting line, and bottle wall thickness remain highly consistent from the first bottle to the last in every production run. This exceptional repeatability is achieved through precision-machined mold components, stable temperature control, and the servo-driven process of the ZQ135, ensuring uniform product quality that meets the strictest quality control standards in regulated industries.

Injection Blow Molding Machine Maintenance Tips

1. Regular Lubrication and Mechanical Inspection
Perform scheduled lubrication of all moving parts including guide rails, toggle mechanisms, rotary table bearings, and linkage joints according to the maintenance manual. Inspect mechanical components for signs of wear, looseness, or misalignment at regular intervals. Proper lubrication reduces friction, prevents premature component failure, and extends the overall service life of the equipment.

2. Barrel and Screw Cleaning
Clean the injection barrel and screw assembly thoroughly when changing materials or after extended production runs. Residual resin buildup can degrade product quality, cause color contamination, and reduce plasticizing efficiency. Use appropriate purging compounds or manual disassembly cleaning procedures as recommended for the specific resin type being processed on your machine.

3. Heating System and Temperature Controller Checks
Regularly inspect all barrel heater bands, thermocouples, and temperature controllers to ensure accurate and stable heating across all 6+N barrel zones. Faulty heaters or inaccurate temperature readings can lead to uneven plasticization, poor preform quality, and inconsistent bottle wall thickness. Replace worn heater elements and recalibrate temperature sensors on a scheduled maintenance cycle.

4. Cooling Water System Maintenance
Maintain the cooling water system by regularly checking water flow rates, pressure levels (0.3 to 0.4 MPa), and water quality. Clean cooling channels in molds and core rods to prevent mineral buildup and blockage. Insufficient cooling leads to longer cycle times, poor bottle dimensional stability, and uneven shrinkage. Monitor water temperature and flowage to ensure the required 4 m³/h capacity is consistently maintained.

5. Mold and Core Rod Care
Clean and inspect injection molds, blow molds, and core rods after each production run. Apply anti-rust treatment to mold surfaces before storage. Check mold alignment, parting line condition, and cavity surface quality to ensure continued dimensional accuracy and surface finish. Damaged or worn mold components should be repaired or replaced promptly to avoid producing defective bottles that fail quality inspection.

6. Servo Motor and Electrical System Inspection
Inspect servo motors, absolute encoders, drive controllers, and electrical wiring connections on a regular basis. The servo system is the heart of this all-electric machine, and any degradation in servo performance directly affects cycle time, positioning accuracy, and product quality. Keep electrical cabinets clean and free of dust, verify grounding integrity, and monitor servo alarm logs for early fault detection.
