A. High-continuity production, reducing downtime losses The "injection-blowing" integrated process of the injection-blow machine itself reduces downtime for process connection, but modern equipment further reduces non-production time and improves equipment utilization (OEE, overall equipment efficiency) through detail optimization:
• Quick mold change system: Traditional mold change requires manual removal of mold bolts and calibration positioning (taking 30-60 minutes), while the injection-blow machine is equipped with a "magnetic/snap-on quick mold change device" - the mold and equipment are fixed by strong magnetic adsorption or mechanical snap-on, with "locating pin + laser alignment" (positioning accuracy ±0.02mm), the mold change time is shortened to 5-10 minutes (for example, switching from the production of 50ml medicine bottles to 100ml medicine bottles, only the mold cavity needs to be replaced, and there is no need to re-adjust the core parameters). For multi-variety, small-batch production (such as cosmetic bottles, with a daily output of 10,000-20,000 pieces of a single variety), the mold change downtime can be reduced by more than 30%. • Automatic feeding and waste material processing linkage: Raw materials are automatically transported to the hopper through the "vacuum loader" (can store 2-4 hours of consumption), and a "material level sensor" is installed in the hopper. When there is a shortage of materials, an alarm will be automatically sounded and the spare hopper will be started to replenish materials (no need for frequent manual feeding); at the same time, a small amount of waste materials generated during production (such as bottle mouth residual materials, trial mold waste) will be crushed by the "online crusher" and directly mixed with new materials (ratio ≤10%) for reuse, avoiding downtime and cleaning caused by waste accumulation (traditional downtime is required for 20-30 minutes for cleaning). • Fault self-diagnosis and early warning: The equipment has a built-in "fault database" (including 500+ common faults, such as hydraulic oil leakage and heating coil damage), and the status of key components (such as hydraulic system pressure fluctuations and motor current abnormalities) is monitored in real time through sensors. For example, if the temperature of a certain heating coil is continuously lower than the set value (deviation>5℃), the system will judge it as "heating coil disconnection", and immediately pop up a fault location diagram (marking the specific heating coil number) and prompt the replacement steps, shortening the maintenance time from the traditional 1-2 hours to within 30 minutes.

B. Deep automation integration to reduce manual dependence The injection blow molding machine can be seamlessly connected with upstream and downstream equipment to form a "fully automated production line", which is especially suitable for scenarios with high labor costs or high cleanliness requirements (such as pharmaceutical workshops):
• Fully automatic pickup and palletizing: After blow molding, the robotic arm (equipped with food-grade silicone suction cups) picks up the parts from the mold (pickup time ≤ 1 second) and directly transports them to the "cooling conveyor belt" (the cooling time is set according to the size of the product, such as about 5-8 seconds for a 30ml bottle). After cooling, another group of robotic arms palletizes them in a "stacked" manner (10-20 pieces per layer, 1-1.5 meters high). There is no human contact throughout the process (to avoid fingerprint contamination or bump deformation). Only one person is required to monitor a single device, which saves more than 60% of manpower compared to traditional manual pickup (requiring 2-3 people). • Cleanroom-adaptive design: For pharmaceutical packaging (such as infusion bottles and vaccine bottles), the equipment adopts a "fully enclosed structure" - dust covers are installed in the barrel and mold area (positive pressure is maintained inside to prevent external dust from entering), the hydraulic system uses "food-grade hydraulic oil" (no volatile pollutants), and all parts in contact with raw materials (screws, barrels) are "electrolytically polished" (smooth surface without dead corners, and can be sterilized with high-temperature steam), meeting GMP cleanroom standards (Class 8 and above). • Production data traceability: The equipment is equipped with an MES system to automatically record data such as "raw material batch, molding temperature, production time, and test results" for each batch of products (storage period ≥ 3 years). If quality problems are found later, the batch number can be traced back to the specific production period and equipment parameters (for example, if the sealing of a batch of medicine bottles is unqualified, it can be checked whether the blow molding pressure during that period is abnormal), meeting the "full traceability" requirements of the pharmaceutical industry.

C. Adapt to special structural products and expand product forms. Through mold and process optimization, the injection blow molding machine can form complex structures that are difficult to achieve with traditional blow molding to meet customized needs:
• Special-shaped bottle mouth and one-piece molding structure: For example, the "bottle mouth + pump body base" of the cosmetic press pump is integrated into one molding - traditional split production requires injection molding of the pump body first and then welding it to the bottle body (easy to leak), while the injection blow molding machine can directly form the bottle mouth thread and pump body slot (accuracy ±0.05mm) in the blow molding stage, without the need for secondary assembly, and the sealing performance is improved by more than 80% (the leakage rate is reduced from 0.5% to below 0.1%). • Compatible with thin-walled and thick-walled products: It can produce "thin-walled lightweight" products (such as 500ml mineral water bottles, with a wall thickness of 0.2-0.3mm) - through "high-speed blow molding" (blowing pressure 1.5-2MPa, blowing time 0.5-1 second) to achieve rapid molding; it can also produce "thick-walled load-bearing" products (such as 5L chemical barrels, with a wall thickness of 2-3mm) - through "segmented pressure holding + slow blow molding" (pressure holding time extended to 5-8 seconds, blow molding pressure 0.8-1.2MPa) to avoid shrinkage marks in thick-walled parts due to uneven cooling. • Multi-cavity synchronous molding: For small-sized products (such as 10ml oral liquid bottles), the injection blow molding machine can be designed with "4-cavity, 8-cavity or even 16-cavity molds", that is, one-time injection molding + blow molding to produce 4-16 products at the same time (each cavity is independently controlled to avoid the overall production being affected by the failure of a certain cavity). Taking an 8-cavity mold as an example, the single-mold cycle is 15 seconds, and the daily output can reach 8×(3600/15)×24=46080 pieces, which is 8 times more efficient than single-cavity equipment, and the consistency of each product (weight deviation ≤1%) is better than multi-machine division of labor production.
