Jiangsu Purui Machinery Co., Ltd.

Company Profile

Jiangsu Purui Machinery Co., Ltd., formerly known as Zhangjiagang Purui Plastics Machinery Co., Ltd., is a national-level high-tech private enterprise dedicated to the R&D, manufacturing, and domestic and international export of complete sets of equipment for recycling waste plastics. The brand was first established in Zhangjiagang in 2006; in 2021, its production base was relocated to Rugao City, Nantong, Jiangsu Province, marking a brand upgrade and rebranding. The company now operates a self-built factory covering an area of 18,600 square meters, equipped with a machining workshop, an assembly area, a closed-loop environmentally friendly painting booth, a material‑testing and commissioning zone, and storage facilities for raw materials and finished products, enabling fully independent, closed‑loop production across the entire process—from component machining and complete machine assembly to factory‑level debugging and eco‑friendly coating. With a registered capital of RMB 20 million, the company specializes in ML‑series soft‑material pelletizing machines, single/dual‑screw extrusion pelletizing equipment, PET bottle‑flake pelletizers, fully automatic plastic film and woven bag washing lines, shredders, crushers, and comprehensive auxiliary machinery. Its equipment is suitable for processing various types of waste plastics—including PE, PP, BOPP, BOPET, CPP, OPP films, woven bags, ton bags, fibers, nonwoven fabrics, PET fabrics, spun yarns, mineral water bottles, PC/ABS engineering plastics, and PLA biodegradable waste—enabling resource‑recovery and recycling.

Russia’s KuibyshevAzot Chemical Plant PA6 Synthetic Fiber Recycling Pelletizing Project

This project provides a closed-loop recycling solution for PA6 synthetic fiber waste, custom‑designed for KuibyshevAzot, a major Russian chemical enterprise. Addressing key industry challenges—such as the fluffy nature of PA6 fiber waste, which makes feeding difficult; thermal degradation during high‑temperature pelletizing; substandard performance of recycled material; and high costs associated with raw material procurement and waste disposal—the system integrates a dedicated pre‑compression feeding unit, a low‑temperature, precisely temperature‑controlled extrusion process, and a multi‑stage, high‑precision filtration and pelletizing line. These features comprehensively resolve issues like feed slippage, production‑capacity fluctuations, and material degradation. The equipment supports 24/7 continuous, stable operation, enabling 100% in‑plant closed‑loop reuse of factory‑generated fiber waste and spinning offcuts. The resulting recycled pellets maintain a viscosity retention rate exc

Philippines · Coftaph

This project provides a customized, dedicated hard‑material recycling and pelletizing solution for an HDPE plastic‑product manufacturing plant on a Philippine island. Addressing numerous operational challenges—such as the island’s high humidity, unstable power supply, abundant impurities in recycled HDPE pipes and plastic drums, limited local spare parts, and difficult maintenance—the system is equipped with an SJ160 HDPE hard‑material recycling and pelletizing production line. The equipment features an integrated washing process that thoroughly removes dirt, sand, and contaminants from the feedstock; a thickened, wear‑resistant alloy screw and cutting tool designed to handle materials with high impurity content; and a proprietary wide‑range voltage electrical control system that accommodates fluctuating island power conditions. Complemented by a full set of wear‑prone components, the system ensures long‑term, reliable operation. With stable throughput and superior pellet quality, it s

Poland · ARGUS MASZYNY SP.Z.O.O.

This project provides ARGUS MASZYNY SP.Z.O.O., a Polish manufacturer of specialty modified plastics, with a high-end twin-screw compounding and pelletizing solution. Addressing the shortcomings of conventional single-screw equipment—such as inadequate impurity removal, inability to perform online compounding and modification, low product added value, and failure to meet stringent material standards for automotive electronics—the solution is integrated with a TSSK65 twin-screw extrusion pelletizing line. Leveraging the powerful shear‑mixing capabilities of co‑rotating parallel twin screws, the system enables one‑step processing of material melting, thorough impurity removal, glass‑fiber reinforcement, and toughening‑based compounding. Paired with a vacuum degassing system, it effectively eliminates volatile contaminants, streamlining the production process and enhancing pellet quality. This supports the company in phasing out low‑end, general‑purpose plastic pellet capacity, enabling ma

Germany · Innova Composites GmbH

This project provides Innova Composites GmbH, a German industrial composite materials company, with a compliant closed-loop recycling and pelletizing solution for nonwoven waste. Addressing key industry challenges—including stringent German environmental regulations, high disposal costs for nonwoven waste, bridging and slippage during the feeding of fluffy materials, and rigorous ESG assessments under the EU Circular Economy framework—the project has customized an ML130SJ140 nonwoven recycling and pelletizing production line. The equipment is equipped with a pre‑compression, forced‑feeding system that fully resolves the issue of stable feeding for bulky nonwovens, while a low‑temperature extrusion process preserves fiber properties. The entire system complies with EU CE certification and German industrial electrical standards, enabling 24‑hour continuous operation. This solution enables 100% in‑plant recovery and reuse of nonwoven edge trimmings and nonconforming products, significantl

United States · Fortune Plastic Inc.

This project provides Fortune Plastic Inc., a leading plastic‑recycling company on the U.S. West Coast, with a customized high‑end PE film recycling and pelletizing solution. Addressing key operational challenges—stringent U.S. recycled‑material quality standards, uneven output from conventional equipment, high failure rates, low automation, and elevated labor costs—the solution incorporates the ML180SJ200 PE‑film‑specific pelletizing line. The equipment is compatible with North American 480V/60Hz industrial power and complies with UL safety standards, featuring dual‑stage vented extrusion and a heavy‑duty forced‑feed system tailored for processing highly fluffy, high‑moisture packaging films, greenhouse films, and stretch‑wrap films. Paired with a high‑precision pelletizing system and a remote monitoring module, it enables automated, stable production. The equipment delivers precise output with low impurity levels, producing pellets that meet U.S. FDA food‑contact grade standards, sig
