Grace Machinery CO., Ltd. products

The Parallel Twin-Screw Extruder is engineered for high-efficiency plastic extrusion processes, providing versatile applications primarily in water, electrical, and drainage pipelining. Its robust design features an extrusion output that is 15% larger, optimizing production throughput while adhering to less stringent material formulations. The improved plasticization quality is attributed to the 36:1 L/D ratio, where the preheating and plasticizing zone has been elongated by 30%, resulting in a more consistent material quality. This extruder is available in several models with varying power and pipe diameters, making it adaptable to different industrial needs. The GMPT series, ranging from GMPT 75/36 to GMPT 135/36, supports pipe dimensions from 400-1200 mm and power capacities from 45 to 160 kw. Designed for efficient performance, it promises swift returns on investment, thus delivering tangible benefits for manufacturers in the aggressive pipeline market.

The PVC-O Pipe Extrusion Line represents an advanced technological process used to enhance the properties of PVC pipes. By transforming standard PVC-U pipes through biaxial orientation, both axially and radially, this line aligns polymer chains into a structured, mesh-like format. The result is a pipe with substantial improvements in strength, toughness, and impact resistance, making it suitable for high-pressure and demanding applications. Key applications include pressure drainage, sewage systems, water supply, and gas distribution networks. Compared to traditional PVC-U pipes, PVC-O pipes boast superior impact and fatigue resistance, elasticity, strength, and crack propagation resistance. The extrusion line adheres to global standards like ISO 16422-2014 and others, ensuring international compliance. Grace's solution offers enhanced automation for precision and efficiency, significantly reducing material waste and costs, thus delivering a consistent, reliable output suited for diverse industrial applications.

The Double-Stage Film Agglomeration and Pelletizing Line is designed for the efficient processing of various plastic materials, including LDPE, PP, films, fibers, and non-woven fabrics. Notably, it handles high-moisture and contaminated raw materials through advanced filtration and dewatering stages. The system`s flexible configuration allows it to adapt to different materials and customer specifications. It is constructed using high-quality components such as 38CrMoAlA and Cr12MoV to ensure durability and consistent performance. With a focus on energy efficiency, it incorporates advanced screen changers and granulation technologies, including water ring and string options, to maintain productivity and reduce downtime. This equipment also features customizable elements like air-fed hoppers and adjustable die faces, optimizing performance across a range of processing tasks.

The PET Bottle Recycling System is designed to process various PET materials into recycled PET (rPET) for diverse applications such as food-grade bottles, fibers, sheets, and packaging materials. This system efficiently recycles PET bottle bales, sheets, and packaging tapes while ensuring comprehensive purity and quality of the end product. With a production capacity ranging from 500 to 6000 kg/h, it incorporates technical features like a 98% efficient wastewater recovery system, and an optional additive recovery to enhance product value. The system's centrifugal and thermal drying technology maintains product moisture levels below 1%, which is essential for producing high-standard rPET flakes. Automation and adaptive adjustments improve operational efficiency, and various sorting equipment maintain a purity level of 99.5% for both color and material. Furthermore, this technologically enhanced system offers remote support and over-the-air upgrade services, tailored to meet the demands of modern recycling processes in a sustainable manner.

The PVC Mixing Unit by Grace is engineered for efficient plastic processing, offering a sophisticated solution for the preparation of PVC compounds. It features a fully automatic control system with a robust computer interface that manages multiple formulations, real-time dynamic monitoring, and provides fault alerts. The double-seal system ensures airtight operation, while the pneumatic opening system facilitates easy access. The mixer incorporates a big tilt angle vane that enhances material flow for adequate cooling through its cooling jacket. The unit is equipped with a plunger-type valve and axial seal to prevent leakage, complemented by a top cover degassing device to eliminate water vapor. The frequency conversion speed regulator allows precise motor control, minimizing power surges and optimizing speed adjustments. Designed with technical precision, the unit enhances production flexibility and reliability, ensuring consistent product quality in plastic manufacturing processes.
