KITECH Completes PE Pelletizing Machine Factory Acceptance Test for Uzbekistan Pharmaceutical Packaging Manufacturer

For pharmaceutical packaging manufacturers, recycling production scrap requires more than simply achieving a target output. The recycled material needs to be processed with stable plasticization, high-precision laser filtration, consistent pellet formation, and reliable machine performance.

This was particularly important for a pharmaceutical packaging manufacturer in Tashkent, Uzbekistan, which needed to recycle clean medical-grade PE production scrap.

The customer required a plastic pelletizing equipment with a target capacity of 200–300 kg/h. Because the recycled material was related to medical packaging production, the customer paid close attention to laser filtration accuracy, fine-contaminant removal, black-spot control, material loss, and pellet consistency.

Before shipment, the customer arranged a Factory Acceptance Test (FAT) at KITECH's factory.

For the test, KITECH used the customer-specified LG BB120 PE material from South Korea, with an MFI of 0.3. The machine achieved a final test output of up to 450 kg/h, significantly exceeding the customer's original 200–300 kg/h target range.

The FAT provided the customer with a direct opportunity to verify the complete PE pelletizing machine, filtration performance, production stability, and finished pellet quality before shipment to Uzbekistan.

1. Project Overview: PE Pelletizing for Medical-Grade Production Scrap

The customer is a pharmaceutical packaging manufacturer based in Tashkent, Uzbekistan. Its production process generates clean PE scrap that can be recovered and converted into recycled pellets.

Unlike general-purpose plastic recycling applications, this project placed greater emphasis on material cleanliness and laser filtration performance.

The customer therefore needed a reliable PE pelletizing machine capable of processing the specified PE material while maintaining stable extrusion and high-quality filtration.

Customer Requirements

The main requirements included:

• Material: Customer-specified LG BB120 PE from South Korea
• MFI: 0.3
• Application: Recycling of clean medical-grade PE production scrap
• Target capacity: 200–300 kg/h
• Actual FAT output: Up to 450 kg/h
• Filtration requirement: High-precision laser filtration
• Quality concerns: Fine contaminants, black spots, pellet consistency, and material loss
• Operational requirement: Stable and continuous production

The combination of a relatively low MFI material and strict cleanliness requirements made plasticization and melt filtration two of the most important aspects of the project.

2. Factory Acceptance Test Using Customer-Specified LG BB120 Material

The FAT was conducted after the plastic pelletizing equipment had been manufactured, assembled, and prepared at KITECH's factory.

Rather than testing the machine only with general-purpose PE material, KITECH followed the customer's material specification and used LG BB120 PE with an MFI of 0.3 for the test.

This allowed the customer to evaluate how the completed plastic pelletizing line performed with the material characteristics relevant to their application.

2.1 Complete Pelletizing Process Verified

The FAT covered the major processing stages of the recycling system:

Material Feeding → Plasticizing & Extrusion → High-Precision Laser Filtration → Water-Ring Pelletizing → Drying → Finished Pellet Inspection

During the test, the machine operated continuously and steadily. The extrusion process remained stable, while the water-ring pelletizing system produced well-formed and consistent pellets.

The customer was therefore able to evaluate the performance of the complete system rather than inspecting individual components separately.

2.2 Actual Output Reached 450 kg/h

One of the most significant results of the FAT was the production capacity.

The customer's original target was 200–300 kg/h, while the KITECH machine achieved an actual test output of up to 450 kg/h using the specified LG BB120 PE material.

This means the tested output exceeded the upper end of the customer's original target by approximately 50%.

The result demonstrated that the selected plastic pelletizing machine had sufficient processing capacity for the customer's planned production requirements while maintaining stable operation during the factory test.

3. High-Precision Laser Filtration for Medical-Grade PE Scrap

For this project, filtration performance was particularly important.

When recycling PE production scrap associated with pharmaceutical packaging, even relatively small contaminants can affect pellet appearance and downstream processing performance. Therefore, the customer placed strong emphasis on fine impurity removal and black-spot control.

KITECH's laser filtration system was therefore an important part of the recycling solution.

3.1 Filtration Fineness Up to 100 Mesh

The laser filtration system provides filtration fineness of up to 100 mesh, allowing the system to remove fine contaminants from the molten plastic before pelletizing.

For applications where material cleanliness is a key requirement, higher filtration precision can help reduce the presence of fine impurities in the recycled melt.

During the FAT, the customer was able to directly inspect the filtered material and finished pellets and evaluate the filtration performance of the completed PE pelletizing machine.

3.2 Improved Black-Spot and Fine-Contaminant Control

Black spots and fine impurities are among the quality issues that plastic recyclers need to control when producing clean recycled pellets.

The high-precision filtration system works together with stable extrusion to help maintain a cleaner melt before pelletizing.

The finished pellets from the FAT showed:

• Uniform appearance
• Consistent pellet size
• Clean surface quality
• Stable pellet formation
• No obvious black spots observed during the test

This filtration performance was especially relevant to the customer's medical-grade PE production scrap recycling application.

3.3 Low Material Loss and Convenient Maintenance

In addition to filtration precision, material recovery efficiency is also important for recycling operations.

The system is designed with a material loss rate of approximately 1–3%, helping reduce valuable PE loss during filtration.

The filter screens can typically operate for 2–6 months, depending on material cleanliness and operating conditions, while screen replacement can generally be completed within approximately 30–40 minutes.

This combination of filtration precision, material recovery, and convenient maintenance helps reduce unnecessary production downtime and operating costs.

4. Efficient Plasticization and Stable Pelletizing

High filtration accuracy alone is not enough to produce consistent recycled pellets. The plasticizing and extrusion process also needs to remain stable.

The optimized screw and barrel configuration of the KITECH plastic pelletizing equipment is designed to provide efficient plasticization and stable melt delivery.

Under applicable processing conditions, the system can help increase output by up to 30%, while maintaining efficient energy use and supporting continuous operation.

During the Uzbekistan FAT, the machine successfully processed the specified LG BB120 PE with an MFI of 0.3 and achieved a test output of 450 kg/h.

The stable extrusion process also provided a consistent melt flow for the subsequent filtration and water-ring pelletizing stages.

5. Automated Operation for Continuous Recycling

The KITECH plastic pelletizing machine incorporates automated controls to simplify operation and reduce manual intervention.

The integrated control system helps operators monitor key production parameters and manage the main processing stages from a centralized interface.

The filtration system also reduces the need for frequent manual screen-changing operations, helping minimize operator involvement and potential operating errors.

For manufacturers planning long-term continuous recycling production, these features can help improve production consistency while reducing labor requirements.

6. Customer FAT Completed Before Shipment

After the test was completed, the customer inspected the machine operation and finished recycled pellets.

The FAT confirmed the key performance indicators required for the project, including:

• Stable machine operation
• Actual output of up to 450 kg/h
• High-precision laser filtration
• Consistent pellet formation
• Good pellet appearance
• No obvious black spots observed during the test
• Stable processing of the specified LG BB120 PE material

The project followed a clear verification process:

Machine Manufacturing → Factory Assembly → FAT with Customer-Specified Material → Performance Verification → Customer Acceptance → Shipment to Uzbekistan

This process allowed the customer to verify the actual performance of the PE recycling machine before installation at their production facility.

7. Why Factory Acceptance Testing Matters

For industrial plastic recycling projects, machine performance should be verified before the equipment leaves the manufacturer's factory.

A Factory Acceptance Test gives customers an opportunity to evaluate:

• Actual processing capacity
• Extrusion stability
• Melt filtration performance
• Pellet appearance and consistency
• Equipment configuration
• Control system operation
• Overall machine performance

More importantly, using customer-specified raw materials can provide a more meaningful evaluation than testing with a generic material.

In this project, KITECH used LG BB120 PE with an MFI of 0.3, allowing the customer to evaluate the machine under material conditions relevant to the planned application.

The final output of 450 kg/h also gave the customer additional confidence that the selected equipment could meet and exceed the original production target.

8. A High-Precision PE Pelletizing Solution for Clean Production Scrap

For pharmaceutical packaging manufacturers, clean PE production scrap represents an opportunity to recover valuable materials and reduce production waste.

However, recycling such materials requires careful control of the entire process.

The key is not simply achieving high output, but balancing:

Stable Plasticization → High-Precision Melt Filtration → Effective Impurity Removal → Consistent Pelletizing → Stable Production

The Uzbekistan FAT demonstrated this approach in practice.

Using the customer's specified LG BB120 PE material with an MFI of 0.3, the KITECH plastic pelletizing line achieved a test output of up to 450 kg/h, exceeding the customer's original 200–300 kg/h target.

At the same time, the integrated laser filtration system with filtration fineness up to 100 mesh provided the high-precision melt filtration required for this cleanliness-focused application.

The successful FAT allowed the customer to verify the machine's capacity, filtration performance, pellet quality, and operating stability before shipment.
