The capacity of plastic bucket-making machine determines their efficiency, profitability, and competitiveness when it comes to making plastic buckets. For manufacturers, the average capacity of plastic bucket-making machines is of concern when purchasing, and it involves the operation arrangement of their entire production workshop. In this blog guide, we will explore with you the range of its capacity and the factors that affect it.

Factors affecting the capacity of the plastic bucket making machine

The capacity of the plastic bucket making machine is affected by many factors, including machine specifications, mold design, material properties, the clamping force, injection rate, and cycle time of different specifications of the equipment. In simple terms, machines with higher clamping forces can accommodate larger molds. The higher the clamping pressure, the more firmly the two parts are fixed, and higher clamping forces also help to shorten the cycle time, thereby increasing potential production. The injection rate determines how fast the molten plastic is injected into the mold, affecting the production cycle’s speed. In addition, the design and quality of the mold used will also affect the cycle time and product quality, and the efficient operation of the operator also plays a role in optimizing and improving production capacity.

Machine specifications and their impact on production capacity

There are several aspects to the specifications. The clamping force of a plastic bucket making machine is usually between 200 and 2000 tons. Higher clamping force generates greater pressure between the molds and allows the handling of larger molds. Different injection rates also vary greatly. Higher injection rates can fill the mold faster, shorten cycle time, and increase production. The design and diameter of the screw affect the injection speed. Screws with high-speed injection designs can process more material in a shorter time, thereby increasing production. Higher injection speeds shorten the duration of the injection phase, thereby shortening cycle time and increasing productivity.

The cycle time of the entire injection molding process, including mold closing, injection, cooling, and mold opening, is also a key determinant of production capacity. To improve the cycle time, in addition to efficient cooling systems and mold opening designs, injection molding robots, and other auxiliary equipment are also needed throughout the production process to simplify operation time and increase production capacity.

The role of mold design in production capacity

Mold design is another critical factor affecting the production capacity of plastic bucket making machines, which can be divided into single-cavity molds and multi-cavity molds. Single-cavity molds produce one bucket per cycle, while multi-cavity molds can produce multiple buckets simultaneously. Multi-cavity molds increase production capacity by increasing the number of units produced per cycle. However, they also require more complex design and precision to ensure consistent cavities. The design and placement of cooling channels within the mold are essential. An efficient cooling channel cools the plastic evenly, reducing cooling time, which is also essential to the overall cycle time. Faster cooling speeds result in shorter cycle times, directly increasing production capacity.

Material properties and their impact on output

The type of plastic material used in the injection molding process also affects the capacity of the plastic bucket making machine. Common materials include HDPE, PP, and PVC. Each material has different flow characteristics, cooling time, and shrinkage, which affect cycle time and total output.

Lower-viscosity materials make it easier to flow into the mold cavity, thereby reducing the required injection pressure and filling time. This can shorten cycle time and increase productivity. High-viscosity materials require more extended pressure and filling time.

The melting temperature of the plastic resin affects the heating of the molding cycle. Materials with lower melting points require less energy and shorter heating time, which helps to shorten the molding cycle and increase production capacity. Materials with high thermal conductivity calm and solidify faster, reducing cooling and overall cycle time. Therefore, selecting resins that meet the requirements and are compatible with the plastic bucket is necessary while optimizing processing parameters such as injection pressure, temperature, and cooling time based on material properties to ensure efficient production.

Production capacity of plastic bucket making machine

Knowing so many factors that affect the production capacity of plastic bucket making machines, what is its production capacity? There are machines of different specifications and models in Topstar, each with a different production capacity. On average, these machines can produce 50 to 100 barrels per hour, depending on the specific model and configuration and the size of the plastic barrel. Small machines are usually used for limited or specialized products and may produce about 100 per hour. In contrast, some large plastic barrels may produce about 50 per hour.

Choose the right equipment

Plastic barrel manufacturers can make relevant decisions on equipment investment and production strategy by considering machine specifications, mold design, material properties, etc. As technology continues to advance, the functions of plastic barrel making machines will continue to be updated and iterated while also providing manufacturers with opportunities for high output and efficiency.
