In the modern era of recycling and waste management, the Plastic Color Sorting Machine and Plastic Polymer Sorter have emerged as essential tools in improving efficiency and accuracy in the sorting process. These machines play a crucial role in separating various types of plastic materials based on their colors and polymer types, leading to better recycling outcomes. Whether it’s distinguishing between PET and non-PET materials, or sorting HDPE, PP, PVC, and other polymers, these machines have become indispensable in industries that deal with plastic recycling.

Key Features of Plastic Color Sorting Machines

Plastic color sorting machines are built with advanced technology designed to identify and differentiate between different types of plastics. The following are some of the most important features:

1. High-Precision Optical Sensors:

These machines are equipped with sophisticated optical sensors capable of detecting subtle differences in plastic materials based on color, transparency, and chemical composition. This precision ensures that even plastics with similar visual characteristics, such as HDPE and PP, can be accurately sorted.

2. Automated Processing:

Unlike traditional manual sorting, which is labor-intensive and prone to human error, plastic color sorting machines use automation to process large volumes of plastic quickly and accurately. This not only speeds up the sorting process but also reduces labor costs and increases efficiency.

3. Multi-Stream Sorting:

Some machines are capable of sorting multiple types of plastics in a single pass, differentiating between PET, HDPE, PVC, PP, and more. This versatility makes them suitable for use in recycling facilities dealing with mixed plastic waste streams.

4. Customization and Adjustability:

Plastic color sorting machines can often be customized or adjusted to suit the specific needs of a recycling plant. Whether it’s sorting by color, polymer type, or transparency, users can program the machine to focus on specific materials or grades, ensuring optimal recovery rates.

5. Energy Efficiency:

Modern plastic sorting machines are designed to minimize energy consumption, using smart technology to optimize operations. This reduces operational costs and lowers the environmental impact, making them more sustainable over the long term.

The Benefits of Using a Plastic Color Sorting Machine

Implementing a plastic color sorting machine in the recycling process offers several substantial benefits:

1. Improved Sorting Accuracy

Perhaps the most significant advantage is the increase in sorting accuracy. Manual sorting often leads to mistakes, as different types of plastics can be difficult to distinguish by eye. Optical sorting technology, however, uses sensors to identify even minute differences in color and material composition, ensuring a higher degree of precision.

For example, in recycling facilities that process beverage bottles, PET and HDPE bottles often get mixed together. A plastic sorting machine can easily distinguish between these two materials based on their color and physical properties, separating them for more effective recycling.

2. Increased Efficiency and Throughput

Plastic sorting machines significantly increase the speed at which materials can be processed. Human workers might be able to sort a few hundred kilograms of plastic per day, but automated machines can process several tons of plastic in the same amount of time. This increased throughput allows recycling facilities to handle higher volumes of waste, leading to greater profitability and a larger positive impact on the environment.

In practice, a plastic sorting machine can handle complex waste streams, such as post-consumer plastic from households or industrial packaging waste. For example, a facility tasked with recycling automotive plastics will face a wide variety of plastic types, from ABS to PP. A plastic color sorting machine will help sort these materials faster and more efficiently than manual methods ever could.

3. Reduction in Labor Costs

One of the key economic advantages of using a plastic sorting machine is the reduction in labor costs. Since the machine performs much of the work automatically, fewer staff members are needed to oversee the sorting process. This frees up workers to focus on other tasks, reducing overall costs for the recycling facility.

Moreover, automation reduces the risk of injury associated with manual sorting, as workers are no longer exposed to hazardous materials or repetitive strain injuries caused by sorting large volumes of plastic by hand.

4. Higher Quality Recycled Plastic

By improving sorting accuracy, plastic sorting machines contribute to producing higher-quality recycled plastic. When different types of plastic are mixed together, the quality of the recycled material is compromised, limiting its use in new products. For instance, if PVC is mixed with PET, the resulting recycled material may not meet the standards required for food-grade packaging or other high-value applications.

With a plastic color sorting machine, plastics are sorted more accurately, resulting in purer batches of material that can be used to create higher-quality recycled products. This improves the value of the recycled material and increases the overall sustainability of the recycling process.

5. Environmental Impact

Effective sorting not only leads to better recycling outcomes but also helps reduce environmental harm. By properly sorting plastics, recycling plants can divert more materials from landfills, reducing pollution and conserving resources. Furthermore, improved recycling rates help reduce the need for virgin plastic production, which is associated with high energy use and greenhouse gas emissions.

Use Cases of Plastic Sorting Machines

1. PET Bottle Recycling:

In many countries, recycling centers deal with vast quantities of plastic bottles, primarily made from PET. Sorting PET bottles from other types of plastic, such as HDPE, is crucial to maintaining the quality of recycled plastic. The introduction of plastic color sorting machines has improved the efficiency of PET recycling by automatically separating PET from other materials like caps, labels, and different polymers.

2. E-Waste Recycling:

In the electronics industry, e-waste recycling involves handling a complex mix of plastics, metals, and other materials. Plastic sorting machines can distinguish between different types of plastic found in electronic devices, such as ABS and PC, making it easier to recycle these materials effectively.

3. Mixed Plastic Waste Management:

Municipal recycling facilities often receive mixed plastic waste from households, which may include a variety of plastics such as PVC, PP, and HDPE. Plastic color sorting machines help efficiently process these waste streams, reducing contamination and ensuring that each type of plastic is properly recycled.

Real-World Case Study: European Plastic Recycling Facility

A European plastic recycling facility recently installed an advanced plastic color sorting machine to handle mixed plastic waste from packaging. The machine was programmed to differentiate between PP, HDPE, and PET plastics. Since its installation, the facility has seen a significant improvement in its sorting efficiency, processing up to 30% more material each day while reducing contamination rates by 25%.

By automating the sorting process, the facility has also been able to reduce its labor costs by 15%, while the quality of the recycled plastic has improved to the point that the company now supplies higher-grade recycled materials to the automotive and consumer goods industries.

Plastic color sorting machines have revolutionized the recycling industry by increasing accuracy, efficiency, and the quality of recycled materials. From separating PET bottles to handling complex e-waste streams, these machines provide a practical solution to one of the most pressing challenges in modern recycling. They reduce the need for manual labor, improve the purity of recycled plastics, and contribute to more sustainable waste management practices. As recycling efforts continue to expand worldwide, the adoption of plastic sorting machines is set to play an increasingly vital role in creating a circular economy for plastics.

ABS (Acrylonitrile Butadiene Styrene) and PS (Polystyrene) are the most widely used plastics in the appliance manufacturing industry.ABS is widely used in the housings and internal components of appliances such as refrigerators, washing machines and televisions, and in toy materials due to its excellent toughness, impact resistance, and excellent machinability.PS has become an ideal choice for the housings of many products due to its light weight, transparency, and good moldability. PS is the ideal choice for many product housings due to its light weight, transparency and good moldability.

With their unique properties, these two plastics have become indispensable and important materials in the manufacture of home appliances, providing a strong guarantee for the durability and aesthetics of the products. At the same time, with the increasing awareness of environmental protection, the waste home appliance recycling industry is gradually exploring the recycling and reuse of these plastics to promote sustainable development.

ABS and PS sorting difficulties when these appliances are retired from service, their road to recycling is full of challenges. Similar physical properties, complex mixing state, so that the sorting has become extremely difficult, but also hinder the recycling of resources.

Similar physical properties ABS and PS are extremely similar in appearance and texture, and both have good molding and impact resistance. This similarity makes it difficult to quickly identify and accurately categorize them during manual sorting or preliminary mechanical sorting.

Recycling mixing problems In the appliance recycling process, mixed plastics of ABS and PS have insignificant differences in IR spectral recognition, increasing the complexity of sorting. Other materials mixed in the recycling process also interfere with the sorting process.

Technological limitations although advanced technologies such as optical sorting are being gradually applied, the sorting accuracy of many manufacturers' equipment is still low, which limits the popularization of the technology and makes the sorting purity in the recycling process face troubles.

Our newest polymer sorter, is another brand new addition to the GIMAX miscellaneous materials purification family, bringing together cutting-edge technology and innovative design to change the rules of the game in the recycling and purification of ABS and PS plastics! This polymer colour sorter is able to accurately identify the micro-differences between ABS and PS plastic materials. After the identification is completed, by driving the high-speed spray valve, the two materials are accurately separated, and the accuracy of the purified product is as high as 99.9%.

High-density polyethylene (HDPE) is a widely used and recyclable plastic. Nonetheless, the presence of polypropylene (PP) contamination poses a significant issue in recycled HDPE streams.

Plastic Mixture

 

Can PP and HDPE be recycled together?
PP and HDPE are distinct types of plastic with different chemical compositions and properties. When they are mixed together in the recycling stream, it can result in various issues:

Reduced quality: Mixing PP with HDPE can lead to lower-quality recycled HDPE material. The properties of the resulting plastic may not meet the required standards for certain applications.

Compatibility issues: PP and HDPE have different melting points and processing requirements. Combining them can make it difficult to maintain the consistency and quality of the recycled material during the melting and molding stages.

Material weakness: The combination of PP and HDPE can result in a recycled material that has reduced strength, durability, and performance. This can be problematic, especially in applications where HDPE's mechanical properties are critical.

Identification and Separation of polymers in the industry
One of the biggest challenges facing the plastics recycling industry today is separating all of the various polymers entering the recycling stream. Separating PP from HDPE during the recycling process can be challenging due to their similar appearance. This can result in contamination if they are not adequately separated at recycling facilities.

To mitigate contamination issues, recycling facilities often employ advanced sorting and separation technologies to ensure that PP and HDPE are properly separated. This involves using optical sorters, air classifiers, and other equipment to identify and separate different types of plastics.

Near Infrared (NIR) Sorting Technology

Among them, the NIR-based sorting machines are widely used in the recycling industry to identify and separate various types of plastics based on their unique spectral signatures in the near-infrared range. These machines can accurately differentiate between different polymer types, such as PET, HDPE, PP, PVC, and more, facilitating the efficient recycling of plastics and reducing contamination in the recycling stream.

The main factors that affect the compressive strength of cartons are: ① raw material quality; ② moisture; ③ box type and flute type; ④ printing and opening; ⑤ processing technology.

a. Raw material quality

The kellicutt formula is used to calculate the compressive strength of cartons based on the ring crush strength of corrugated cardboard, which is an indicator of the compressive strength of cartons. The ring pressure strength is the bonding strength between the core paper and the surface paper or lining paper. The raw material is the main factor affecting the ring pressure strength. It is related to the quantity, tightness, moisture, etc. of the raw material. The grades of containerboard paper and corrugated base paper mainly include A, B, C, D, E, etc. Under normal circumstances, the grade matching principle should be followed when selecting materials. The grade selection of containerboard paper and corrugated base paper should be similar. At the same time, the boxboard The basis weight of paper and corrugated base paper should be maintained within the range of 21, so as to ensure the overall quality level of raw materials and the quality of corrugated board. Of course, corrugated board is volatilized by the surface paper, core paper and lining paper bonded together, so the factors of adhesive and core paper should also be considered. The appropriate moisture content, tightness and uniformity of the core paper are conducive to the adhesion with the surface paper and lining paper. The good adhesive performance of the adhesive and the appropriate thickness of the adhesive layer are conducive to improving the compression resistance of the corrugated box. strength.

B.Moisture

The production environment, storage environment, use environment, weather, climate and other factors of the cartons will all affect the moisture content of the cartons. In order to ensure the compressive strength of the cartons, the impact of the external environment on the water content of the cartons should be avoided as much as possible.

The initial moisture content of corrugated base paper will directly affect the board-making quality of corrugated cardboard. If the moisture content is high, the base paper will be soft, but the tensile strength will be relatively reduced; if the moisture content is low, the base paper will be dry, and the top of the corrugated corrugated board will easily crack during corrugation. In the production of corrugated cardboard, the moisture content required to obtain the best strength value is generally 6% to 8%. The traditional method of determining moisture is the drying and weighing method at 105°C, using an oven and a balance. This method is the standard method.

C. Box type and corrugated type

Box type refers to the type of box and the size ratio of boxes of the same type, which have a significant impact on compressive strength. Some cartons are made of double-layer corrugated cardboard, and their compressive strength is significantly higher than that of single-layer boxes of the same specifications. Under the same conditions, the higher the box, the worse the stability and the lower the compressive strength.

In people's consciousness, they often think that the larger the flute type, the higher the compressive strength of the carton, and it is easy to ignore the impact of the flute type on the deformation. The larger the flute type, the greater the compressive strength and deformation of the carton; the smaller the flute type, the smaller the compressive strength and deformation of the carton. If the carton is too large, but the flutes are very small, the carton will be easily stained during the compression test; if the carton is too small, but the flutes are very large, the deformation will be too large during the compression test, and the buffering process will be long and effective. The deviation between the force value and the final force value is too large.

D. Printing and opening

Printing will cause certain damage to corrugated cardboard, which will reduce the compressive strength of the carton. The size of the pressure and the size of the bearing area are a major factor affecting the compressive strength of the carton. If the printing pressure is too high, the corrugations will easily be crushed and the flute height will be reduced. Especially when printing at the pressure line, in order to force and clear printing at the pressure line, the entire cardboard will be crushed and the compressive strength of the carton will be greatly reduced. Therefore, printing here should be avoided as much as possible. When printing graphics and text on the full page or around the carton, in addition to the pressing effect of the impression roller on the corrugated cardboard, the ink also wets the paper surface, which in turn reduces the compressive strength of the carton. When a general carton is fully printed, its compressive strength drops by about 40%.

For products that require ventilation in packaging, opening holes on the box surface or punching handle holes on the side of the box will reduce the strength of the carton, especially if the opening area is large or biased to one side, etc., the impact will be more obvious.

E. Processing process deviation

Through experiments, it was found that under the same conditions, for every 1mm widening of the transverse pressure line of the carton, the compressive strength of the carton decreases by 90N-130N, and the deformation increases by about 2mm. If the pressure line is too wide, the force value of the carton will increase slowly during the 1 compression test, the effective force value will be small, and the final deformation will be large. In order to ensure the compressive strength, we should try our best to improve the production process and reduce the impact of each process on the compressive strength of the carton. Improper crimping during the box making process, too deep grooves, weak bonding, etc. will also reduce the compressive strength of the box.
