Why Is It Important To Sort Plastic For Recycling?

As global plastic consumption continues to rise, scientific classification has become the first line of defense to solve the recycling problem. Unsorted mixed plastics not only reduce the recycling value, but also pollute the recycling chain - for example, PVC impurities may release chlorine during the melting process, destroying the performance of other plastics. The use of best plastic recycling sorting equipment for waste management can accurately separate different polymers to ensure the quality of recycled raw materials while reducing energy waste by more than 30%. This technological upgrade directly promotes the circular economy from concept to large-scale practice.

 

 

As the main consumer of plastics, the manufacturing industry urgently needs systematic changes. Industrial plastic sorting solution for manufacturing plants integrates near-infrared sorting and airflow screening technology through modular design, which can process scraps and defective products in real time at the end of the production line. Taking the recycling of automotive injection molded parts as an example, the equipment can distinguish between materials such as ABS and PP, allowing 95% of waste to re-enter the production cycle. This closed-loop management not only reduces the cost of raw material procurement, but also helps factories meet stringent regulations such as the EU Plastic Strategy and create sustainable supply chain barriers.

Technological innovation is reshaping industry standards. The AI-powered plastic waste sorting system for sustainable recycling uses a million-level image database to train algorithms that can identify fragment color, transparency, and even surface wear. Compared with traditional photoelectric sorting, the AI system has a 40% higher recognition accuracy for complex mixed waste, especially when dealing with multi-layer composite packaging, it can peel off the aluminum foil and PE layers, breaking through the bottleneck of traditional recycling technology. This intelligence has opened up a new path for processing special plastics such as electronic waste and medical devices.

Why must plastics be segregated for the purposes of recycling

Plastic sorting: the cornerstone of efficient recycling

Plastics must be recycled separately because different polymers (such as PET, HDPE, PVC) have very different chemical properties and melting points. Mixed recycling will cause the quality of recycled materials to drop sharply or even become unusable. For example, unsorted PET bottles and HDPE toy fragments can form fragile and brittle composite materials after melting. This is exactly the key to industrial plastic sorting machine cost analysis - HTsorter uses near-infrared (NIR) spectroscopy and AI algorithms to accurately identify plastic types and ensure sorting purity of up to 99%, avoiding material waste and secondary pollution.

 

 

Balance between cost and performance of automated equipment

Traditional manual sorting is inefficient and costly, while automatic plastic recycling machine price list shows that high-end equipment is often beyond the budget of small and medium-sized enterprises. HTsorter breaks the deadlock through modular design: our equipment starts at only 60% of similar products and supports phased upgrades (such as from basic sorting to multi-layer plastic identification). For example, the standard version of the sorter (300kg/h processing capacity) can reduce annual operating costs by 35%, and the investment payback period is shortened to 18 months, which is particularly suitable for recyclers in emerging markets.

Middle Eastern Client Visit and Aluminum Extrusion Press Recommendation

Recently, a client from the Middle East visited our factory and intended to purchase an aluminum extrusion press for manufacturing door and window materials.

Aluminum Extrusion Machine

We recommended the customer to purchase a 5-inch extrusion press, specifically our 1100T aluminum extrusion press. Through our discussion, we realized that the customer had limited knowledge about extrusion presses. Previously, he used to purchase aluminum materials for making doors and windows, but now he plans to buy an extrusion press to produce aluminum materials himself.

Someone had suggested that he should buy an 1800T aluminum extrusion press for producing door and window aluminum materials. However, based on the sizes of the door and window materials he needs, we recommended the 1100T aluminum extrusion press instead.

 

Our Huanan 1100T aluminum extrusion press is also a 5-inch aluminum extrusion press, which is suitable for extruding various door and window aluminum profiles. The extrusion cylinder specifications of our 1100T aluminum extrusion press machine are:

Diameter: 132mm

Length: 800mm

Applicable aluminum billet size:

Diameter: 127mm

Length range: 400–750mm

 

 

Considerations When Extruding Aluminum: Extrusion Pressure

 

 

extrusion press machine

 

When extruding aluminum, it is crucial to consider the extrusion pressure. If the extrusion press tonnage is too high relative to the aluminum billet diameter and alloy type, the following issues may occur:

1. Over-Extrusion

Excessive Metal Flow Rate: Too much pressure can cause excessively fast metal flow, affecting dimensional accuracy and surface quality.

Overheating: Excessive extrusion pressure can lead to rapid temperature rise, potentially causing surface roughness, cracks, or even burning.

 

2. Mold and Die Damage

Shortened Die Lifespan: Excessive pressure may exceed the die’s load capacity, leading to rapid wear or even breakage.

Die Deformation: Continuous use of an overpowered press can cause plastic deformation of the die, affecting profile accuracy.

 

3. Equipment Damage

Accelerated Extrusion Cylinder Wear: Higher pressure accelerates wear on the inner wall of the extrusion cylinder, shortening its lifespan.

Hydraulic System Overload: If the tonnage is too high, the hydraulic system may overheat, experience pressure failures, or even develop leaks.

 

4. Negative Impact on Product Quality

Coarse Grain Structure: Excessive extrusion speed can lead to larger metal grains, reducing mechanical performance.

Increased Defects: High stress and temperature may introduce bubbles or inclusions inside the aluminum, affecting product quality.

Reduced Dimensional Accuracy: Overpowering the extrusion process may lead to unstable profile dimensions and out-of-tolerance products.

 

5. Increased Production Costs

Higher Energy Consumption: A high-tonnage extrusion press consumes more energy, leading to unnecessary waste if the press is oversized.

Increased Maintenance Costs: Faster wear and tear on molds, extrusion cylinders, and hydraulic systems lead to higher maintenance and replacement costs.

 

 

Choosing the Right Extrusion Press

The similarities and differences between copper extrusion and aluminum extrusion

                   aluminum and copper extrusion processes 

             The similarities and differences between copper extrusion and aluminum extrusion

Aluminum is one of the most common materials in our daily lives and an essential metal in various industries. However, in addition to aluminum, copper is also a widely used metal due to its excellent electrical and thermal conductivity, corrosion resistance, and other favorable properties. Copper has broad applications across multiple industries, such as:

 

Electrical and Electronics: Wires, cables, transformers, motors, and electronic components.

Construction: Piping systems, electrical wiring, and copper conductors.

Automotive: Electrical systems, radiators.

Industrial Equipment: Heat exchangers, valves, pumps, bearings, and gears.

Telecommunications: Cables.

Energy: Solar panels, generators.

Healthcare: Medical devices, surgical instruments, door handles, and handrails due to its antibacterial properties.

Both aluminum and copper are produced through extrusion processes, where pressure is applied to metal billets, forcing them through molds to form the desired shapes. While the basic production process is similar for both materials, copper and aluminum differ significantly in their properties, which affects their production methods and equipment.

 

Production Process:

Both aluminum and copper extrusion processes involve applying hydraulic or mechanical pressure to metal billets, which are heated to increase their plasticity for easier extrusion. The extrusion equipment, including extrusion cylinders, molds, extrusion rods, and heating systems, are similar for both metals. However, because copper and aluminum have different properties, the specific production conditions, such as temperature and pressure, vary.

 

Differences Between Aluminum and Copper:

 

Aluminum:

Density: Low

Melting Point: Approximately 660°C

Plasticity: High, making it easier to extrude

Extrusion Pressure: Relatively low

 

Copper:

Density: High

Melting Point: Approximately 1085°C

Hardness: Higher, making extrusion more difficult

Extrusion Pressure: Higher due to its hardness

Because of these differences, the heating temperature required for aluminum and copper extrusion is not the same. For aluminum, the heating temperature typically ranges from 400°C to 500°C, while for copper, it is generally higher due to its higher melting point. This difference in properties also results in copper requiring higher extrusion pressures compared to aluminum. This is one of the reasons why our HuaNan heavy Industry can produce copper extruders in addition to aluminum extruders.

 

Molds:

Mold material plays a crucial role in determining the extrusion quality. Aluminum extrusion molds are usually made from high-strength steel, offering durability. Copper extrusion molds, on the other hand, require materials with higher wear and heat resistance, making them less durable than aluminum molds.

 

Lubrication:

The choice of lubricant also differs. Aluminum extrusion typically uses graphite or oil-based lubricants, while copper extrusion requires high-temperature lubricants such as glass lubricants to manage the higher extrusion pressures.

 

Cooling:

After extrusion, cooling methods vary. Aluminum cools faster and is typically cooled using air or water, while copper requires a slower, gentler cooling process to prevent cracking.

 

Post-Treatment:

Aluminum often undergoes anodizing or spraying treatments, while copper is usually treated through electroplating or polishing to achieve a smooth finish.

 

Production Costs:

Despite similar production processes, the costs of extruding copper are generally higher than for aluminum due to copper's higher extrusion pressures and material costs.

 

Summary:

In conclusion, while the extrusion processes for aluminum and copper are fundamentally similar, the differences in their material properties lead to distinct requirements for heating, extrusion pressure, mold materials, lubrication, cooling, post-treatment, and cost. Copper extrusion typically involves higher pressures, more specialized molds, and more complex handling, which results in higher production costs compared to aluminum extrusion.
