180-Type Three-Machine Plastic pelletizing machine Operation Case: Quality Upgrade, Dual Improvement of Compliance and Profit for Small Processing Plants

Against the increasingly fierce competition in the plastic recycling industry, many small processing workshops and start-up factories can only produce low-quality granules due to backward equipment technology, with slim profits and constant environmental compliance risks. This cooperative customer is a small waste plastic recycling processing plant located in Shandong, mainly engaged in waste film, woven bag and injection scrap recycling and granulation business. The original old single-unit Plastic pelletizing machine features simple technology, uneven plasticization, excessive operating noise and high energy consumption. The finished granules have numerous black spots and low purity, failing to access medium and high-end orders. Its annual environmental assessment result is always on the warning line, which severely restricts production and operation. In 2025, the customer completed equipment upgrading and purchased our 180-type three-machine Plastic pelletizing machine, achieving all-round upgrading of product quality, compliance and economic benefits after commissioning.

The customer had prominent core pain points before equipment upgrading: First, the old single-unit equipment adopts single-stage plasticization, leading to uneven raw material heating. Films and mixed materials are prone to incomplete melting and scorching, with granule defective rate up to 8% and serious raw material waste, so granules can only be sold at low prices. Second, the equipment has no fine filtration structure, resulting in excessive impurities in finished products, which fails to meet EU PPWR export compliance standards and limits market channels. Third, the equipment has loud noise and high power consumption with high monthly electricity cost, and its noise value repeatedly approaches the EIA over-standard red line, with unstable production performance. Fourth, the equipment has high failure rate and frequent maintenance, causing heavy shutdown loss and extremely narrow overall profit margin.

Combined with the customer’s core demands including small factory site, low daily output, high-quality production demand and compliant commissioning, our engineers accurately matched the 180-type three-machine Plastic pelletizing machine for the customer. Adopting three-machine segmented technology, the equipment solves poor plasticization and excessive impurity problems in a targeted manner. Its low-noise and energy-saving configuration meets environmental EIA standards, and the compact body fits the customer’s narrow factory site, enabling quick commissioning without infrastructure renovation. Featuring simple operation and no need for on-duty staff, it perfectly adapts to the lightweight production mode of small processing plants.

Three months after official commissioning, the customer’s production data was optimized significantly, and the actual upgrading effect exceeded expectations. In terms of product quality, the three-machine segmented melting and fine filtration technology ensures thorough plasticization and complete impurity removal. The finished granules are plump, transparent and uniform, with defective rate dropping from 8% to less than 1%. Tested by a third-party institution, the granule recyclability reaches 72%, fully complying with EU PPWR regulation access standards. The customer successfully received medium and high-end recycled raw material orders, with product unit price increased by more than 20% and greatly expanded profit margin.

In terms of production and compliance, equipped with a 250-type low-noise reducer, the equipment keeps operating noise below 70 decibels, smoothly passing the latest environmental EIA inspection and completely eliminating noise over-standard risks without production restrictions. The energy-saving heating system delivers remarkable performance, cutting overall energy consumption by 25% compared with old equipment and saving thousands of yuan on electricity bills every month. Meanwhile, the powerful feeding system eliminates material blockage and slipping faults, greatly improving continuous operation stability with nearly zero failure rate. It effectively reduces shutdown maintenance loss and steadily improves production efficiency, with stable daily output of about 4 tons to meet daily production demands.

On-site customer feedback: The 180-type three-machine plastic granulator fully adapts to production demands of small factories. It is sturdy, power-saving, quiet and easy to operate, completely solving old equipment’s drawbacks including poor quality, high energy consumption and non-compliant performance. It not only improves product premium greatly, but also obtains new compliant orders. With low investment cost and fast payback period, it is a cost-effective choice for small recycling plants to upgrade equipment.

This case fully verifies that the 180-type three-machine Plastic pelletizing machine can perfectly solve small plastic recycling plants’ pain points including low-end product quality, high energy consumption, EIA restrictions and low profit, relying on core advantages of high-quality three-machine technology, energy saving, low noise, compliance and durability. It helps micro and small enterprises realize standardized, compliant and efficient production.
