A. Innovation and stability of equipment structure • High-precision mold clamping system: using servo hydraulic compound drive (clamping force control accuracy ±1%), template parallelism ≤0.02mm/m (calibrated by laser), avoiding product flash caused by mold gap during blow molding (flash thickness ≤0.03mm), and extending mold life (conventional molds can be produced more than 500,000 times). • Double-station turntable design: Some models use "injection-blow molding" double-station turntable structure (rotation positioning accuracy ±0.1°), and the preform after injection is directly rotated to the blow molding station to reduce transmission errors, which is suitable for high-speed production (such as turntable speed 10-20 rpm, corresponding to a production capacity of 1200-2400 pieces/hour).

B. Process expansion and special functions • Multi-layer co-injection blow molding: supports 2-5 layers of co-extrusion (such as PE + barrier layer EVOH), to achieve improved barrier properties of products (oxygen permeability reduced by 90%), suitable for packaging that needs to be protected from light and oxidation (such as edible oil bottles, sauce bottles). • No waste corner design: The sprue material generated during the injection process can be directly recycled through a crusher (the proportion of recycled materials ≤ 20%), there is no waste edge in the blow molding process (precise cutting through the mold edge), the material utilization rate is more than 98%, and the waste is reduced by 70% compared with the traditional extrusion blow molding process.

C. Human-computer interaction and intelligent management • Touch screen visual operation: equipped with a 10-15 inch high-definition touch screen, supports 3D simulation production (real-time display of screw speed and mold temperature curve), the fault diagnosis system can automatically locate the problem (such as the alarm response time <5 seconds when the heating ring is damaged), and lower the operating threshold. • Industrial Internet of Things (IIoT) integration: Support OPC UA protocol access to the factory MES system, upload production data (such as production capacity, energy consumption, defect rate) in real time, realize remote monitoring through the cloud platform (data refresh frequency 1 time/second), and facilitate centralized management of multiple devices.

D. ​​Environmental protection and safety design • Low noise operation: The hydraulic system uses a silent pump (noise ≤75dB), and the mold area is equipped with a soundproof cover (noise reduction 10-15dB), which meets the OSHA workshop noise standard (8 hours exposure ≤85dB). • Safety interlock mechanism: Set up a double sensor for the mold safety door (mechanical lock + infrared sensor), and the equipment will stop immediately when the door is opened (response time <0.1 second), and the heating area is equipped with overheating protection (automatic power off when overtemperature 10℃) to ensure safe operation.

E. Customization and industry segmentation adaptation • Solutions for special products: ◦ Production of special-shaped bottles: Through adjustable blow molding molds (such as petal-shaped and square bottles), combined with multi-axis linkage control, non-circular cross-section products can be formed (such as cosmetic special-shaped bottles with a demolding success rate of ≥99%); ◦ Products with inserts: Metal threaded inserts can be embedded in the injection process (positioning accuracy ±0.2mm), and the bonding strength between the insert and the bottle body after blow molding is ≥50N (pull-out test), which is suitable for medical bottles that require high-strength interfaces. • Micro injection-blow technology: Develop micro injection-blow machines (clamping force 5-10 tons), with a minimum molding volume of 0.1ml (such as insulin pen matching bottles), and a screw diameter of only 12mm, which is suitable for high-precision production of medical microcontainers (dimensional tolerance ≤±0.05mm).

F. Maintenance and cost optimization • Quick replacement of wearing parts: The screw and barrel adopt modular design (flange connection), and the replacement time is less than 30 minutes; the heating ring adopts magnetic suction installation (disassembly and assembly efficiency increased by 50%) to reduce downtime maintenance costs. • Long-cycle maintenance design: The hydraulic system uses long-lasting anti-wear hydraulic oil (replacement cycle 1-2 years), the servo motor is maintenance-free (lifespan ≥ 50,000 hours), the overall equipment comprehensive failure rate is <0.5 times/1,000 hours, and the operation and maintenance cost is reduced by 40% compared to traditional equipment.
