In the chemical, energy, and logistics sectors, 30L Jerry Cans (oil tanks) serve as core packaging containers. Their production efficiency and quality directly impact a company's operating costs and market competitiveness. A highly adaptable and stable extrusion blow molding machine is crucial for achieving efficient and high-quality production of 30L Jerry Cans. This article will comprehensively introduce this extrusion blow molding machine, specifically designed for 30L Jerry Cans, from the perspectives of technical configuration, production advantages, and applicable scenarios, unlocking the "accelerator code" for packaging production.
Core Technology: Tailor-Made for 30L Jerry Can Production
This extrusion blow molding machine's technical design is tailored to the molding requirements of 30L Jerry Cans. Its refined configuration addresses the production challenges of traditional equipment, including low efficiency, high defective product quality, and high energy consumption. Key technical highlights include:
1. High-Precision Extrusion System: Ensures Uniform Raw Material Melting
Equipped with a servo-driven extruder, a customized screw (28:1 aspect ratio) and a barrel heating system, this machine precisely controls the melt temperature (with an accuracy of ±2°C) and extrusion speed (adjustable from 0 to 80 kg/h) of common plastic materials such as HDPE and PP. Compared to traditional equipment, this results in more uniform raw material melting, effectively preventing wall thickness variations in 30L Jerry Cans caused by uneven melt flow. This results in a stable wall thickness accuracy of within ±0.1mm, far exceeding the industry average of ±0.3mm, significantly improving the container's pressure resistance and service life.
2. Dual-Cavity Intelligent Die: Doubles Production Capacity and Ensures Consistency
To meet the production scale requirements of 30L Jerry Cans, the equipment utilizes a dual-cavity, simultaneous molding die. The die cavity is CNC-machined to an accuracy of 0.005mm, ensuring identical dimensions and temperature distribution in both cavities. In actual production, the equipment enables "one-shot mold closing, two-piece molding." Combined with a 15-second/cycle rapid cooling system, the hourly production capacity reaches 480 pieces, a 100% increase over single-cavity equipment. Furthermore, dual-cavity, simultaneous control technology eliminates the significant weight variation associated with traditional dual-cavity equipment. The weight deviation of each 30L Jerry Can is controlled within ±5g, ensuring consistency throughout batch production.
3. Fully Automatic Closed-Loop Control System: Reduces Manual Work and Minimizes Errors
The machine is equipped with a fully automatic PLC closed-loop control system, integrating the entire process from extrusion - mold closing - blow molding - cooling - demolding - finished product inspection. Process parameters (such as blow molding pressure of 0.8-1.2 MPa and cooling time of 12-20 seconds) can be set with a single click via the touchscreen. The system monitors each step in real time and automatically adjusts. Furthermore, the machine is equipped with a visual inspection module that detects cosmetic defects (such as scratches, bubbles, and poor seals) in 30L Jerry Cans online, automatically rejecting unqualified products. This process eliminates the need for manual intervention, reducing labor costs by 50% and increasing the product qualification rate to over 99.5%.
4. Energy-saving Cooling and Power System: Reduces Costs and Consumption
To control energy consumption, the equipment utilizes a variable-frequency cooling water pump and servo power motor. The cooling system automatically adjusts the pump speed based on mold temperature, saving 30% energy compared to traditional fixed-frequency systems. The servo motor's power output dynamically adjusts according to production load, avoiding energy waste caused by "a large horse pulling a small cart." The power consumption for producing each 30L Jerry Can is only 0.3 kWh, lower than the industry average of 0.5 kWh. Over time, this can save companies significant energy costs.
Production Advantages: Solving Industry Pain Points and Improving Overall Efficiency
For 30L Jerry Can manufacturers, the implementation of this extrusion blow molding machine can address multiple production pain points, significantly improving overall efficiency:
1. Breaking the "Capacity Bottleneck": More Efficient Order Delivery
Traditional single-cavity extrusion blow molding machines only produce 200-250 30L Jerry Cans per hour, often leading to delivery delays for large orders. This dual-cavity machine, however, boasts an hourly capacity of 480 pieces and supports 24/7 operation (with a failure rate of less than 0.5%). Based on a 25-day production month, monthly production capacity can reach 288,000 pieces, an increase of over 80% compared to traditional equipment. This allows companies to easily cope with peak season orders and seize market opportunities.
2. Eliminating the "Defective Product Problem": Stable Quality Earns Customer Recognition
As packaging containers for hazardous materials such as chemicals and fuels, the quality of the 30L Jerry Can is directly related to transportation safety and customer trust. This equipment utilizes high-precision extrusion, simultaneous molding, and online inspection technologies to control key product specifications such as wall thickness deviation, weight deviation, and sealing performance within stringent limits. Third-party testing has shown that 30L Jerry Cans produced by this equipment exhibit no leakage at 1.2 MPa and no damage after a drop test (from a height of 1.5 meters). This fully complies with national and industry standards such as GB/T 19160-2016, helping companies secure long-term customer relationships.
3. Reduced "Overall Cost": Significantly Reduced Operational Pressure
In addition to the direct benefits of increased production capacity and reduced defective rates, the equipment offers significant cost advantages in labor, energy consumption, and maintenance. Fully automated control reduces the labor costs of two operators; the energy-saving system saves approximately 5,000 yuan in electricity bills monthly; and core components (such as the screw and die) are made of high-strength, wear-resistant materials, resulting in a service life of over three years, 50% longer than traditional equipment, reducing maintenance and replacement costs. Overall, the equipment can help companies reduce unit production costs by 15-20%.
Applicable Scenarios and Adaptability: Meeting Diverse Production Needs
This 30L Jerry Can extrusion blow molding machine not only specializes in standard product production but also boasts robust adaptability, meeting the personalized needs of diverse industries and specifications:
1. Multi-Industry Adaptability: Comprehensive Coverage from Chemicals to Logistics
The 30L Jerry Cans produced with this equipment can be widely used in the chemical industry (industrial lubricants, coatings), energy (diesel, alcohol), logistics (turnover storage materials), and other fields. By adjusting the raw materials (such as using antistatic HDPE for hazardous goods packaging) and process parameters (such as increasing the wall thickness to 5mm for increased pressure resistance), the specific requirements of different industries can be met without replacing core components, providing exceptional flexibility.
2. Specification Adjustment Capability: Minor Modifications Adapt to Similar Products
In addition to the standard 30L Jerry Can, the machine also supports fine-tuning within the 25-35L capacity range. Simply replace the die cavity (the machine features a built-in quick-change interface, allowing mold changes in as little as 30 minutes) and adjust the extrusion speed and blow molding pressure to produce similar plastic containers, such as 25L and 32L. This eliminates the need to purchase new equipment, helping companies expand their product offerings and improve equipment utilization.
Technical Support and Service: Worry-Free Production from Start to Finish
To ensure stable operation, users enjoy comprehensive technical support and service. After delivery, professional engineers will visit the machine for installation and commissioning, operator training (including parameter setting, routine maintenance, and troubleshooting). During operation, 24/7 online technical consultation is available. Furthermore, regular inspection and replacement of core components (screw and die) are provided, ensuring worry-free production throughout the entire process.
