Extrusion system
Our plastic bottle molding machines are fitted with an extrusion system that represents the pinnacle of modern engineering. The automatic temperature - controlling device, sourced from a world - leading brand, is the beating heart of this system. In the extrusion process, plastic materials undergo a complex transformation from solid pellets to a flowing, malleable state. Precise temperature regulation is not just an advantage; it's a necessity. Different polymers, such as the widely used PET for clear beverage bottles or HDPE for durable detergent containers, have unique melting points and processing windows.
The state - of - the - art temperature controller offers an accuracy that is second to none, with a tolerance of ±0.3°C in premium models. This remarkable precision ensures that the plastic is in an ideal molten state as it approaches the extrusion die. For instance, in the production of high - end pharmaceutical bottles, where even the slightest variation in material properties can impact product integrity, this level of temperature control is indispensable. Any deviation from the optimal temperature can lead to issues like inconsistent melt flow, which may result in uneven wall thickness in the final bottle.
Driving the screw is an innovative electromagnetism motor reducer, a technological marvel that enables seamless stepless regulating. This feature empowers operators to fine - tune the extrusion process with unprecedented precision. When working with a viscous engineering plastic, such as polycarbonate used in safety - critical applications, a higher torque can be dialed in to push the material through the die. Conversely, for less viscous materials like LDPE used in lightweight packaging, a lower torque and higher rotational speed of the screw can be selected. This adaptability not only enhances the quality of the extruded plastic strands but also significantly boosts the overall productivity of the machine.
Clamping device
The clamping device in our machines is a masterpiece of design, featuring a bi - directional synchronous clamping mechanism with a double - axis single - cylinder configuration. This setup is engineered to provide rock - solid stability during the plastic bottle molding process.
During the injection and molding phases, the molds must be held together with utmost precision. The bi - directional synchronous clamping ensures that the clamping force is evenly distributed across both the horizontal and vertical axes. This is crucial because any imbalance in force can cause misalignment between the mold halves. Such misalignment can lead to a host of defects in the final product, including uneven wall thickness, flash (excess plastic around the edges), and distorted shapes. The double - axis design further enhances the stability by providing a more uniform clamping action.
The single - cylinder, despite its uncomplicated appearance, is a powerhouse. It is capable of generating substantial clamping forces, making it suitable for handling molds of various sizes and complexities. When manufacturing large industrial drums, which require a significant amount of force to keep the molds tightly closed during the injection of molten plastic, our clamping device rises to the occasion. It not only ensures that the plastic is properly shaped but also extends the lifespan of the molds by minimizing wear and tear caused by uneven stress distribution.
Blowing device
Our plastic bottle molding machines are equipped with an upper - blowing type blowing device, a design that offers several distinct advantages in the production of plastic bottles.
When the molten plastic pre - form is ready to be transformed into a bottle, the upper - blowing mechanism takes center stage. This method allows for a highly controlled and uniform distribution of air pressure. The result is a more even expansion of the plastic, leading to bottles with consistent wall thickness and flawless shapes. In the production of delicate cosmetic bottles, where aesthetics and functionality are equally important, the upper - blowing device shines. It can precisely shape the intricate neck and shoulder areas, ensuring a perfect fit for caps and pumps. The air being directed from the top gives operators greater control over the shaping process, reducing the risk of imperfections.
Compared to other blowing methods, the upper - blowing type significantly reduces the likelihood of air pockets or uneven inflation. In traditional blowing techniques, air distribution can be uneven, leading to thin spots or bulges in the bottle walls. Additionally, the upper - blowing design is more energy - efficient. It requires less air pressure to achieve the desired bottle formation, which not only cuts down on energy consumption but also lowers operational costs.
Hydraulic system
The hydraulic system in our plastic bottle molding machines is a paragon of reliability and performance, incorporating world - famous brand controlling components and a sophisticated proportional controlling circle.
The use of top - quality controlling components is a testament to our commitment to delivering a machine that can withstand the rigors of continuous industrial use. These components, including valves, pumps, and actuators from renowned manufacturers, are designed to operate flawlessly under high - pressure conditions. The world - class build quality ensures minimal leakage and long - term durability, reducing the need for frequent maintenance and downtime.
The proportional controlling circle is a key differentiator of our hydraulic system. It enables operators to precisely control the hydraulic flow and pressure. For example, during the injection process, the proportional control can rapidly adjust the hydraulic pressure to ensure a quick and complete filling of the mold. When the machine switches to the mold - opening and - closing phase, the pressure can be carefully modulated to prevent any damage to the molds. This level of control not only optimizes the efficiency of the machine but also significantly improves the quality of the plastic bottles produced. By fine - tuning the hydraulic system, we can reduce cycle times and increase overall productivity.
Electric controlling system
Our plastic bottle molding machines are equipped with an advanced electric controlling system, with a programmable controller from B&R Austria at its core. B&R, a global leader in industrial automation, brings a wealth of innovation and intelligence to our machines.
The programmable controller is highly adaptable and can be customized to manage every aspect of the machine's operation. From the moment the machine is powered on, it undertakes a comprehensive self - diagnostic sequence, checking the status of all components to ensure a smooth start - up. During production, it coordinates the seamless operation of the extrusion system, clamping device, blowing device, and hydraulic system. If there is a change in production requirements, such as a switch to a different bottle size or a new plastic material, the programmable controller can be easily reprogrammed to adapt.
Every electric component in the system is sourced from world - famous brands, guaranteeing consistent performance, reliability, and compatibility. The motors, sensors, and relays work in harmony to provide a stable and efficient operation. The sensors, in particular, play a crucial role by accurately detecting various parameters such as temperature, pressure, and position. They provide real - time feedback to the programmable controller, which then makes instant adjustments to maintain optimal operating conditions. For example, if the temperature in the extrusion barrel begins to deviate from the set point, the controller can immediately adjust the heating or cooling elements to bring it back to the desired temperature. This ensures the consistent production of high - quality plastic bottles.
