ZQ40 इंजेक्शन ब्लो मोल्डिंग मशीन (यूरोपीय)

Step 1: Preform Injection

During the preform injection stage, raw plastic material is heated and injected into the injection mold cavity through the precisely controlled screw and barrel system. The bottle neck, including threads and sealing surfaces, is molded with high dimensional accuracy at this station. The injection process is carefully controlled in terms of temperature, pressure, and timing to ensure that the parison (preform) has the correct shape, weight, and material distribution. Once the preform has sufficiently cooled and solidified to maintain its shape, the mold opens and the mandrel carrying the preform is transferred by the rotary table to the blow molding station for the next stage of production.

Step 2: Blow Molding

At the blow molding station, compressed air is introduced through the core rod mandrel to inflate the heated preform outward against the walls of the blow mold cavity. The bottle shape and final dimensions are determined by the blow mold design, and the number of cavities at this station depends on the target bottle size. As the pressurized air expands the parison, the softened plastic conforms precisely to the internal contours of the mold, creating a seamless, uniform container body. After a brief cooling period to set the bottle shape, the blow mold opens and the rotary table advances the mandrel and finished bottle to the stripping station.

Step 3: Stripping

At the stripping station, the finished bottles are automatically ejected from the cooled core rods by the stripping mechanism. The ejected bottles are then conveyed to downstream equipment for inspection, labeling, or packaging. Critically, all three actions of the injection blow molding process (injection, blowing, and stripping) operate simultaneously at their respective stations. While one set of preforms is being injected, another set is being blown into bottles, and a third set of completed bottles is being stripped. This concurrent operation is the key to the high efficiency, rapid cycle times, and minimal material waste that characterize this injection blow moulding machine.

Operation Precautions for the IBM Machine

1. Pre-Operation Safety Inspection
Before starting the injection blow molding machine, operators must perform a thorough safety inspection of all mechanical, electrical, and pneumatic systems. Verify that emergency stop buttons are functional, all safety guards are properly installed, the compressed air system is at the required pressure (0.7-1.2 MPa), and the cooling water supply is flowing at the correct pressure and temperature. Document all pre-start checks according to the daily maintenance logbook.

2. Material Preparation and Pre-Drying
Ensure that raw material is properly dried to the manufacturer-recommended moisture content before feeding into the hopper. Excessive moisture in materials like HDPE, PP, or PS can cause surface defects, bubbles, and inconsistent wall thickness during the injection process. Use a material dryer set to the correct temperature and duration for each specific resin type, and inspect material for contamination or foreign particles before loading.

3. Temperature Zone Monitoring
Closely monitor the barrel heating zone temperatures (3+N zones) to ensure they reach and maintain the correct processing temperature for the specific material being used. Improper temperature settings can lead to incomplete melting, material degradation, uneven flow distribution, and defective preforms. Allow adequate soak time for the barrel to reach uniform temperature before beginning production, and check temperature controller readings regularly during operation.

4. Mold Installation and Alignment
When installing or changing molds on the ZQ40, ensure precise alignment between the injection mold, blow mold, and stripping mechanism with the rotary table positions. Misalignment can cause mold damage, uneven clamping, and defective products. Follow the manufacturer's torque specifications for all mold mounting bolts, and verify the mold cooling channel connections are leak-free before starting trial runs with the new tooling setup.

5. Regular Maintenance Schedule Compliance
Adhere strictly to the recommended preventive maintenance schedule for the servo motors, rotary table bearings, screw barrel assembly, and all drive components. Lubricate designated points at the specified intervals, inspect wear parts such as screw tips and check valves for signs of degradation, and replace worn components promptly. Regular maintenance prevents unexpected downtime and ensures the machine maintains its precision and efficiency over its full operational lifespan.

6. Shutdown Procedure and Barrel Purging
Follow the correct shutdown sequence when stopping the injection blow molding machine. Purge the barrel with appropriate purging compound or transition material to remove residual resin and prevent carbonization during idle periods. Gradually reduce barrel temperatures according to the material specifications, switch off the cooling water supply only after the machine has sufficiently cooled, and engage all safety locks before leaving the machine unattended.

Common Troubleshooting for Injection Blow Molding Machine

Uneven Wall Thickness
If the finished bottles exhibit uneven wall thickness, check the preform temperature uniformity, core rod alignment, and injection pressure balance across all cavities. Misaligned core rods or inconsistent barrel zone temperatures are the most common causes. Verify that the hot runner system is distributing material evenly, inspect the core rod concentricity, and adjust the injection parameters to ensure balanced filling across all mold cavities.

Incomplete Blow Molding / Thin Spots
When bottles show thin spots or incomplete blow molding, the issue typically relates to insufficient blow air pressure, excessive preform cooling before the blow stage, or incorrect parison temperature distribution. Check that the compressed air supply is within the 0.7-1.2 MPa operating range, verify the timing between injection and blowing stations, and adjust the preform temperature profile for more uniform material stretching during inflation.

Flash or Burrs on Parting Line
Flash or excess material along the mold parting line indicates insufficient clamping force, worn mold surfaces, or excessive injection pressure. Inspect the mold mating surfaces for wear, debris, or damage. Ensure the clamping force is properly set (the ZQ40 supports 40-80 ton adjustable clamping), clean the mold parting surfaces, and reduce injection pressure or speed if the flash persists after mechanical checks are completed.

Bottle Sticking to Mold or Core Rod
If bottles are not releasing cleanly from the mold or sticking to the core rods at the stripping station, check the mold surface condition, cooling channel temperatures, and stripping mechanism operation. Excessive mold temperature, insufficient cooling time, or worn stripping components can all cause adhesion problems. Polish mold surfaces as needed, increase cooling water flow, and verify the stripping stroke reaches the full 220mm travel.

Short Shots or Incomplete Filling
Short shots occur when the mold cavities are not completely filled with material. Common causes include insufficient injection pressure, low barrel temperature, clogged hot runner nozzles, or inadequate material supply from the hopper. Increase injection pressure and speed, raise barrel zone temperatures gradually, inspect and clean hot runner channels, and verify that the material feed system is operating without blockages or bridging in the hopper.

Surface Defects (Streaks, Bubbles, Sink Marks)
Surface imperfections such as streaks, bubbles, or sink marks may result from moisture in the raw material, excessive barrel temperature causing material degradation, trapped air, or inadequate packing pressure. Ensure the material is thoroughly pre-dried, check barrel temperatures for signs of overheating, verify the venting in the mold is clear, and increase holding pressure and time to compensate for material shrinkage during cooling.
