A. Extreme material utilization, reducing raw material cost loss
No runner/hot runner design, reducing waste generation: The "casting system" (such as main runner and branch runner) of traditional injection blow molding machines will produce 3%-5% of waste (need to be recycled and crushed for secondary use), while modern injection blow molding machines use "hot runner + no runner mold"-
The hot runner system is heated at a constant temperature (the temperature is consistent with the barrel, the deviation is ≤±2℃), so that the raw materials in the runner are always kept in a molten state and directly enter the cavity for molding, and the runner waste is reduced to less than 0.5% (only a small amount of gate remains);
For small-volume products (such as 10ml medicinal bottles), "no gate molding" can even be achieved, and the raw material utilization rate is increased from 95% to more than 99%. Based on an average daily production of 100,000 products and a raw material unit price of 20,000 yuan/ton, the raw material cost can be saved by about 800-1000 yuan per day.
Precise metering and low-material alarm to avoid overfilling: The screw metering adopts "servo motor + electronic ruler closed-loop control", with a metering accuracy of ±0.1g (traditional equipment is ±0.3g), which can accurately control the injection volume according to the weight of the product (such as a 20g cosmetic bottle), avoiding the waste of raw materials caused by "over-injection" or the waste of materials caused by "low-injection"; at the same time, the hopper is equipped with a "material level sensor". When the remaining raw material is less than 1 hour's consumption, it will automatically sound and light alarms and prompt on the operation screen to avoid empty injection due to lack of material (empty injection may wear the screw and barrel).

B. Flexible production design, fast response to multiple specifications
Quick mold change and parameter memory, shortening production change time: For scenarios where product specifications need to be changed frequently (such as changing from 50ml bottles to 100ml bottles), the injection blow molding machine has a "one-button mold change" function -
The mold positioning adopts "precision guide column + magnetic suction auxiliary fixation", and there is no need for repeated calibration when changing molds. The mold change time is shortened from the traditional 30-60 minutes to 10-15 minutes;
The equipment has a built-in "parameter memory library" (which can store more than 100 groups of product parameters). After changing the mold, you only need to call the corresponding parameter group (such as "100mlPET bottle" parameters), and the system automatically matches 20+ parameters such as injection pressure and blow molding time, and the number of mold trials is reduced from 5-8 times to 1-2 times (reducing mold trial waste by 70%).
Adjustable number of cavities, suitable for small batch production: Some injection blow molding machines support "flexible switching of mold cavity number". For example, the same equipment can be installed with "2-cavity, 4-cavity, 6-cavity" molds (adapted by adjusting the clamping force and injection volume). When the order volume drops from 100,000 pieces/day to 20,000 pieces/day, it can be replaced with a 2-cavity mold (avoiding the energy waste caused by the "overcapacity" of the 4-cavity mold), and the energy consumption of a single mold is reduced by 30% (from 4.5kW・h/mold to 3.2kW・h/mold).

C. Convenient after-sales and maintenance, reducing equipment management costs
Remote diagnosis and fault warning, reducing downtime: The device has a built-in "Internet of Things module" that can upload operating data (such as motor current, hydraulic oil temperature, mold pressure) to the cloud platform in real time -
When it detects "hydraulic oil contamination exceeds NAS level 8" (normal should be ≤NAS level 7) or "motor bearing temperature exceeds 65℃" (normal ≤55℃), the system pushes warning information through the mobile phone APP (4-8 hours in advance), and maintenance personnel can prepare spare parts (such as filter elements, bearings) in advance to avoid sudden failures (traditional troubleshooting after the failure occurs, which may cause downtime of 4-8 hours);
Complex faults (such as abnormal molding size) can be retrieved through remote control parameter curves (such as injection pressure-time curves), and engineers can remotely guide debugging (the solution rate is more than 80%), without waiting for on-site maintenance (saving travel expenses and time costs).
Standardization and easy replacement of wearing parts lowers the maintenance threshold: core wearing parts (such as check rings, sealing rings, sensors) use "standardized interfaces" (such as ISO standard sizes), without relying on original exclusive accessories (universal parts can be purchased on the market, reducing costs by 20%-30%); at the same time, the replacement structure design is "humanized" - for example, the screw can be disassembled without disassembling the barrel as a whole, and it can be achieved through the "quick disassembly flange", and the replacement time is shortened from the traditional 2-3 hours to less than 1 hour (ordinary maintenance personnel can operate it, without the need for professional technicians).
