and Automated IBM Injection Blow Molding Machine with Multi-Station Turntable

Product Specification

A. Modular structural design • Three-stage mold frame quick-release system: The injection mold, blow mold, and demolding mechanism are installed in independent modular systems (locating pin accuracy ±0.01mm). There is no need to disassemble the entire mold when replacing molds of different specifications. The hydraulic quick clamping device (clamping force switching time <3 minutes) can achieve rapid switching of 50-500ml product molds (traditional equipment requires more than 2 hours). • Expandable multi-station turntable: Some models are equipped with a 4-6-station turntable structure (rotation positioning accuracy ±5″), which can simultaneously complete the injection, blow molding, cooling, and demolding processes, and improve production efficiency by 40% (e.g., the 6-station equipment has a production capacity of 12,000 bottles/hour), which is suitable for mass production scenarios such as mineral water bottles.

B. Full process automation integration • Robot vision sorting system: Equipped with a 12-megapixel industrial camera (detection speed 200 times/minute), it uses AI algorithms to identify defects such as product shortages, bubbles, and deformation (recognition rate ≥99.5%), and links six-axis robots to remove defective products (rejection accuracy 100%), reducing manual quality inspection costs (saving 80% of quality inspection manpower). • Intelligent feeding closed-loop control: Raw material transportation adopts weightless metering feeding (metering accuracy ±0.5%), real-time monitoring of hopper weight changes, and automatic adjustment of screw speed through PLC (adjustment accuracy ±1rpm) to ensure that the weight fluctuation of each molded product is ≤0.3g (e.g. The weight of the 500ml bottle is controlled at 18.0±0.3g).

C. Adaptability to extreme working conditions • Ultra-high pressure blow molding capability: For thick-walled products (such as industrial containers with a wall thickness of 20mm), a supercharger is equipped to increase the blow molding pressure to 4-6MPa (traditional equipment is only 1-2MPa), and the mold nitrogen rapid pressure relief system (pressure relief time <0.1 second) is used to make the product wall thickness uniformity reach ±5% (better than the ±10% error of traditional equipment). • Special design for low-temperature molding: When processing heat-sensitive materials such as TPU (thermoplastic polyurethane), the injection barrel is cooled by liquid nitrogen (the temperature can be reduced to 80-100℃), and the screw surface is chrome-plated (hardness HV≥1000) to reduce frictional heat generation and prevent yellowing of the material during plasticization (yellowness index YI≤5).

D. ​​Optimization of maintenance and safety details • Lubrication-free pneumatic components: Key moving parts (such as blow needle cylinders) use PTFE-coated seals (friction coefficient 0.05-0.1), no oiling and maintenance required for life, avoiding oil pollution of products (suitable for food packaging scenarios, in line with FDA certification requirements). • Intelligent fault warning system: monitor the operating status of screws, molds and other components through vibration sensors (sampling frequency 10kHz), and issue a warning 30 seconds in advance when abnormal vibration occurs (such as amplitude > 50μm when the screw is stuck), and automatically save process parameters (historical data can be traced back to 10,000 molds).

E. Precision micro-molding technology • Micro-injection unit: For 0.1-1ml micro-products (such as medical sampling tubes), equipped with a micro-injection device (minimum injection volume 0.05ml), piezoelectric ceramics drive injection piston (displacement accuracy ±1μm), product weight repetition accuracy ≤0.1mg, meeting the high-precision requirements of IVD in vitro diagnostic consumables (such as PCR tube capacity error ≤1%). • Nano-coated mold: The mold cavity is coated with diamond-like carbon (DLC) coating (thickness 2-3μm), and the surface roughness is Ra≤0.05μm, which reduces the demoulding force of micro-products by 70% (from 5N to 1.5N), and avoids deformation of thin-walled structures (wall thickness 0.1mm) during demoulding.

F. Multi-material co-injection blow molding technology • Three-layer co-extrusion structure: A/B/A three-layer co-extrusion (such as PE outer layer + EVOH barrier layer + PE inner layer) is achieved through two injection units (main and auxiliary machines), the thickness of the barrier layer is controlled at 5-10μm, and the oxygen permeability is ≤0.1cc/day (traditional single-layer bottles are 5cc/day), which is suitable for packaging that requires long-term preservation, such as sauce bottles. • Two-color injection blow molding: The injection mold is equipped with two sets of independent flow channels (temperature controlled separately), which can produce two-color products (such as transparent bottle body + label color), the color boundary accuracy is ≤0.2mm, and the post-printing process is omitted (such as one-piece molding of the brand logo of the cosmetic bottle body).

G. Customized solutions for special industries • Explosion-proof injection blow molding machine: When used to produce chemical packaging bottles containing solvents, the whole machine adopts explosion-proof design (Ex d IIB T4 Gb certification), the motor and electronic control system are explosion-proof, and equipped with a combustible gas detection device (detection accuracy 0.1% LEL) to prevent the solvent from volatilizing and causing explosions during the production process. • Vacuum injection blow molding technology: Introducing vacuum assistance (vacuum degree - 0.08MPa) during the blow molding stage to make the product fit more closely with the mold. It is suitable for products with complex surface patterns (such as perfume bottles with glass-like texture), and the pattern replication accuracy reaches 95% (traditional blow molding is only 80%).
