A. Design for improving production efficiency and capacity . Multi-station cycle production ◦ Some high-end models adopt a "multi-cavity turntable structure" (such as a 4-cavity/8-cavity turntable), and the injection molding, blow molding, and demolding processes can be carried out simultaneously. The cycle time is shortened to 8-12 seconds, and the production capacity is increased by 3-4 times compared with single-cavity equipment (for example: 8-cavity equipment can produce 5,000 500ml bottles per hour). . Quick mold change system ◦ Equipped with a hydraulic automatic mold locking device (mold change time <15 minutes), the mold positioning adopts guide column + cone double positioning (accuracy ±0.03mm), which reduces downtime and debugging time, and is suitable for multi-variety small batch production (such as frequent changeover of cosmetic packaging).

B. Special structures and functional expansion . Injection-stretching-blow molding integration ◦ For products such as PET bottles that require biaxial stretching, some models integrate "injection molding - stretching - blow molding" three stations (such as Sidel injection-stretching-blow molding equipment), and use the stretching rod to axially stretch the parison (stretching ratio 1:3-1:5) to improve the strength of the product (impact strength increased by 40%) and transparency (light transmittance > 90%). . Bottle mouth thread direct molding ◦ A thread core rotating mechanism (speed 100-200rpm) is set in the mold, and the bottle mouth thread processing (such as 48 teeth/inch standard thread) is completed synchronously during the blow molding process. No post-processing trimming is required, and the thread accuracy reaches ISO 483 standard, which is suitable for screw cap sealing requirements (such as beverage bottles and pesticide bottles).

C. Industry-customized solutions . Special machine for pharmaceutical aseptic production ◦ Designed in accordance with GMP standards: the surface of the equipment is treated with 316L stainless steel mirror (roughness Ra≤0.8μm), the mold area is equipped with a negative pressure dust removal device, and the production process can be connected to RABS (restricted access barrier system), which is suitable for aseptic packaging such as antibiotic bottles and prefilled syringes. . Anti-pollution design for food packaging ◦ FDA-certified materials are used for food contact parts (such as food-grade silicone seals), the heating system uses far-infrared radiation heating (to avoid hot air convection contamination), and an online UV sterilization module (ultraviolet intensity ≥1000μW・s/cm²) can be integrated to meet the hygiene requirements of dairy products and edible oil packaging. . Special configuration for packaging of hazardous chemicals ◦ For strong acid and alkali containers (such as sulfuric acid bottles and sodium hydroxide barrels), the injection blow molding machine can optimize the blow molding pressure curve (segmented pressure control) to make the wall thickness uniformity of the product ≤5%, and improve weather resistance (outdoor service life ≥5 years) by adding the function of adding anti-ultraviolet masterbatch (addition amount 0.5-2%).

D. Maintenance and usability optimization . Lubrication-free component design ◦ Key moving parts (such as guide rails and screws) are made of self-lubricating alloy materials (such as tin bronze + PTFE composite coating), and the maintenance cycle is extended from 500 hours of traditional equipment to 2000 hours, reducing downtime maintenance costs (maintenance costs are reduced by 40%). . Fault self-diagnosis system ◦ The control system has a built-in 200 + fault code library. When an abnormality occurs (such as insufficient pressure, temperature deviation), the touch screen displays the fault location and solution in real time (such as "Mold temperature sensor failure, it is recommended to replace the X-axis sensor"), reducing the technical threshold for maintenance.

E. Compatibility with automated production lines . Robot integration interface ◦ Reserved PLC communication interface (supports Modbus and EtherCAT protocols), which can be connected to a six-axis robot for automatic pickup and sorting, realizing the unmanned full process of "injection blowing - labeling - boxing" (such as the automation rate of beverage bottle production lines reaches 95%). . Online integration of visual inspection ◦ A high-speed visual inspection system can be installed (inspection speed 1000 pieces/minute) to identify defects such as product shortage, deformation, and dimensional tolerance in real time, with an inspection accuracy of 0.1mm, and automatic rejection of defective products (rejection accuracy > 99.5%).

F. Adaptation of new materials and special processes . Processing of high-viscosity engineering plastics ◦ For high-viscosity materials such as PC and POM, the injection blow molding machine uses a large aspect ratio screw (L/D=30-32) and a torque servo motor (torque increased by 30%), and the melt pressure can reach 200MPa to ensure uniform plasticization of the material (melt index fluctuation ≤5%). . Foam injection blow molding ◦ Supports physical foaming (such as injection of N₂) or chemical foaming (addition of foaming masterbatch), and the product density is reduced by 20-40% (such as 30% weight reduction of foamed PP bottles). At the same time, it has both heat insulation and buffering functions, which is suitable for scenes such as thermos cup liners and foam packaging.

G. Energy saving and low-carbon innovation . Waste heat recovery system ◦ The heat generated by cooling the injection molding barrel is recovered through a heat exchanger and used to preheat raw materials or workshop heating (heat recovery rate reaches 30%), which can reduce the consumption of standard coal by about 50 tons per year (calculated based on 10 equipment). .
