Working Principle
Plastic Melting and Extrusion
The production process of 2000 - liter blow - molded water buckets begins with the plastic melting and extrusion stage. High - density polyethylene (HDPE) or other suitable plastic granules are the primary raw materials for these large - scale containers. These granules are carefully fed into the hopper of the extruder.
Once in the extruder, a powerful screw mechanism comes into play. As the screw rotates, it creates a pushing force that steadily moves the plastic granules forward, guiding them into the heating zone of the extruder barrel. This heating zone is equipped with a series of precisely controlled heaters, which can raise the temperature of the barrel to a level suitable for melting the plastic. For HDPE, the typical melting temperature ranges from 130°C to 170°C.
As the plastic granules travel through the heating zone, they gradually absorb heat. The combination of the external heat from the heaters and the internal frictional heat generated by the rotation of the screw causes the granules to soften and eventually melt into a homogeneous, viscous molten state. This molten plastic is then continuously pushed forward by the screw and extruded through a die - shaped opening at the end of the extruder. The die is designed to form the molten plastic into a tubular shape known as a parison. The parison is a crucial intermediate product, as its quality, thickness, and uniformity directly affect the final quality of the 2000 - liter water bucket. For example, if the temperature in the extruder is not evenly distributed, the parison may have inconsistent thickness, leading to weaknesses in the final bucket.
Molding Process
After the parison is successfully extruded, it enters the molding process. The hot parison is quickly transferred and placed into a pre - opened, two - part mold specifically designed for a 2000 - liter water bucket. The mold has a cavity that precisely matches the outer shape of the desired bucket, including details such as handles, ribs for added strength, and any specific markings or logos.
Once the parison is in position, the two - part mold closes tightly around it. Simultaneously, a high - pressure 吹气系统 (blowing system) is activated. Compressed air, typically at a pressure ranging from 0.3 to 1.0 MPa, is forcefully injected into the parison through a nozzle. The high - pressure air causes the parison to expand rapidly, forcing it to conform tightly to the inner walls of the mold cavity. This process is similar to blowing up a balloon inside a rigid container, where the balloon takes on the shape of the container.
As the plastic is expanding and taking the shape of the mold, a cooling system integrated into the mold starts to work. The cooling system usually uses a combination of water - cooled channels within the mold and external air cooling. Cold water circulates through the channels in the mold, absorbing the heat from the plastic. This rapid heat transfer causes the plastic to cool and solidify, gradually taking on the hard and durable form of the 2000 - liter water bucket. The cooling time is a critical factor; if the cooling is too fast, the bucket may develop internal stresses that could lead to cracking during use. On the other hand, if the cooling is too slow, it will significantly reduce the production efficiency.
Once the plastic has cooled and solidified sufficiently, the mold opens, and the newly formed 2000 - liter water bucket is ejected. At this point, the bucket may still have some flash or excess plastic around the edges, which can be trimmed off in a subsequent finishing process. The finished bucket is then ready for quality inspection, where it will be checked for any defects such as holes, uneven walls, or improper shaping before being sent for further applications.
Features and Advantages
High - Quality and Durable Products
The 2000 - liter blow - molded water bucket equipment we offer is engineered to produce top - notch products. The buckets are crafted from high - molecular - weight, high - density polyethylene (HDPE) raw materials. This type of material endows the buckets with remarkable characteristics. For example, they have high rigidity, which means they can maintain their shape even under significant external pressure. In industrial applications where the buckets may be stacked with heavy loads on top, their high rigidity ensures that they do not deform easily.
Moreover, HDPE has excellent creep - resistance. Creep is the tendency of a material to slowly deform under a constant load over time. In the case of our 2000 - liter water buckets, their resistance to creep guarantees long - term dimensional stability. This is crucial for industries that require long - term storage of substances, such as the chemical industry where the buckets may store chemicals for extended periods.
The multi - layer structure of the buckets further enhances their performance. Each layer is formed by the melting and bonding of plastic melt, and the defects in each layer are offset from one another. This significantly improves the bucket's impact resistance. In transportation scenarios, where the buckets may be jostled or dropped accidentally, their enhanced impact resistance reduces the risk of damage. For instance, during the transportation of edible oils in the food industry, a bucket with high impact resistance can better protect the product inside, preventing spills and ensuring the integrity of the goods. Additionally, the outer layer of the bucket is often colored dark (usually blue), which can resist ultraviolet rays and prevent photo - aging. The inner layer, on the other hand, remains in the natural color of the resin, ensuring the purity of the substances stored inside. This combination of features results in a durable product with an extended service life, reducing the need for frequent replacements.
Energy - Efficient and Cost - Saving
Our 2000 - liter blow - molded water bucket equipment incorporates advanced energy - saving designs. One of the key components is the use of servo motors. Servo motors are known for their high - efficiency operation. They can precisely control the speed and torque according to the production requirements, which minimizes energy waste. For example, during the plastic melting and extrusion process, the servo - motor - driven extruder can adjust the rotation speed of the screw in real - time, ensuring that the plastic granules are melted and extruded with the optimal energy input. This not only reduces the overall energy consumption of the equipment but also improves the production efficiency.
In addition, the equipment is designed with optimized heating systems. The heaters in the extruder barrel are equipped with intelligent temperature - control devices. These devices can accurately monitor and adjust the temperature of the heating zone, preventing over - heating and energy over - consumption. By maintaining the plastic - melting temperature within a precise range, the equipment ensures that the plastic is in the best - flowing state for processing while consuming the least amount of energy.
The energy - saving features of the equipment lead to significant cost savings in the long run. Lower energy consumption means reduced electricity bills for manufacturers. Moreover, the improved production efficiency allows for more products to be produced in the same amount of time. For example, compared to traditional blow - molding equipment, our 2000 - liter water bucket equipment can produce 20% more buckets per hour with the same energy input. This increased productivity per unit of energy further reduces the production cost per bucket, making our products more competitive in the market.
