Korean HDPE Recycling Plant Case | KITECH Plastic Pelletizing Equipment
I. Industry Pain Points: Common Challenges in High-End Overseas Plastic Recycling
Manufacturers of high-end plastic containers serving the global semiconductor and pharmaceutical sectors have long been constrained by aging imported recycling equipment. In many hdpe recycling plant projects, traditional machinery still struggles with unstable temperature control and limited automation. When low-melt-index HDPE raw materials are processed on an outdated plastic recycling machine, thermal degradation often occurs, causing recycled pellets to fall short of the strict standards required for high-end product manufacturing. With more than 20 years of experience in plastic recycling and over 800 projects delivered worldwide, KITECH Machinery follows European manufacturing standards and holds CE, UL, and CSA certifications, along with 28 national patents. By providing customized pelletizing solutions, the company successfully upgraded the recycling infrastructure for a leading South Korean enterprise, creating a benchmark hdpe recycling plant for high-end, clean-grade plastic recycling overseas.
II. Client Project Overview
2.1 Client Profile: The client is a leading South Korean company specializing in clean plastic containers for semiconductor chemicals. Its core business focuses on high-chemical-resistance, clean-grade packaging drums and bins for industries such as LCD chemicals, pharmaceuticals, and food. The facility produces its own impurity-free HDPE flakes and plans to establish an internal closed-loop waste recycling line, where recycled pellets can be directly reused in its own production. The client reached out to KITECH through Google. Its core requirement was to replace aging German recycling equipment and upgrade to an automated, intelligent production system powered by a reliable plastic pelletizer.
2.2 Three Core Production Pain Points
1. Aging German hardware and high O&M costs:
The existing imported equipment has been in service for many years, lacks intelligent features, and depends heavily on manual operation. Frequent breakdowns, discontinued OEM spare parts, and rising long-term maintenance costs make stable 24-hour continuous production impossible, creating an urgent need for a new hdpe recycling plant solution.
2. Difficulty controlling critical temperature limits and material quality defects:
The processed material consists of the factory’s own pure, low-melt-index HDPE flakes, with a strict requirement that processing temperatures must not exceed 200°C. The old plastic recycling machine’s temperature control system fluctuates significantly, easily causing thermal degradation of HDPE and compromising material purity and chemical resistance. As a result, the pellets fail to meet the qualification standards for semiconductor and pharmaceutical container production. In addition, the equipment lacks sufficient capacity and cannot meet the stable 400–500 kg/h production target, leading to waste accumulation and a broken recycling loop. A high-precision plastic pelletizer is therefore essential.
3. Dual demand for business expansion and environmental policy compliance:
With steadily growing market orders and increasingly strict South Korean environmental regulations regarding the circular economy, the current low-automation equipment can no longer support large-scale waste recycling. The client urgently needs high-precision temperature control, intelligent operation, and stable high-capacity pelletizing equipment to complete its green recycling system, reduce long-term production costs, and build a more efficient hdpe recycling plant.
III. KITECH Customized Pelletizing Solution (Precisely Addressing Pain Points)
Based on the client’s material parameters, temperature control standards, and production capacity requirements, our technical team recommended a tailored solution centered on the KSP120 single-screw plastic pelletizer and the 1600-series columnar screen changer. This plastic recycling machine configuration directly addresses the client’s production challenges and upgrades the entire hdpe recycling plant process.
3.1 Fully Intelligent Automation to Replace Aging, Inefficient Imported Equipment
The machine is equipped with a dual-station material hopper and a weighbridge equipment, integrated with a remote intelligent control module that allows managers to monitor production capacity, temperature, and energy consumption in real time, significantly reducing dependence on manual labor. The core drive uses a German Transcyko gearbox, ensuring strong operational stability and supporting 24-hour continuous production while achieving 15% greater energy efficiency than traditional equipment. This makes the plastic pelletizer a dependable upgrade for a modern hdpe recycling plant.
3.2 Segmented Independent Water-Cooling Temperature Control System (Strict 200°C Limit)
The screw compressor has two sets of fans for cooling in zones two and three, and the last two zones are equipped with water cooling coils, with independent temperature control using solenoid valves and needle valves. This segmented precision control keeps the processing temperature strictly at or below 200°C, fundamentally preventing the thermal degradation of low-MFI HDPE. By stabilizing the process window, the plastic recycling machine ensures the high-purity quality required for recycled material used in premium container manufacturing.
3.3 Dual Assurance of Capacity and Melt Filtration for High-End Raw Material Production
The equipment delivers a stable processing capacity of 450 kg/h, fully meeting the client’s 400–500 kg/h requirement. Equipped with a high-precision 1600-series columnar screen changer for deep melt filtration, this plastic pelletizer produces dense, glossy pellets free from bubbles and impurities. The result is recycled material that can be directly fed back into high-end container production lines, strengthening the long-term performance of the hdpe recycling plant.
IV. One-Stop Full-Process Foreign Trade Implementation Service

V. Multiple Core Values of Project Implementation
1. Quality Value: Exclusive low-temperature control technology completely solves the pain point of HDPE thermal degradation. The cleanliness and mechanical properties of recycled granules meet the production standards of semiconductor- and pharmaceutical-grade containers, significantly improving the yield rate of finished products. This is the key value of a well-designed hdpe recycling plant.
2. Production Efficiency Value: Stable capacity meets target output; intelligent production lines reduce labor input; and the failure rate of the new plastic recycling machine is significantly lowered, saving substantial annual maintenance costs. A high-performance plastic pelletizer therefore improves both productivity and operating stability.
3. Long-Term Development Value: Establishing a closed loop for self-production and self-use of waste materials within the factory area complies with South Korea’s green environmental protection policies, helping the client consolidate its leading position in high-end clean plastic containers and achieve high-value recycling of waste plastics. The result is a more sustainable, more efficient hdpe recycling plant.
