Coperion K.K. List of Products and Services

We have developed the "STS Mc11 Tandem Mixing Processing System" as a dedicated machine for temperature and shear-sensitive plastics. Backed by Coperion's advanced processing know-how, this system consists of a twin-screw extruder "STS Mc11" and a single-screw extruder. In addition to achieving highly reproducible and stable product quality with a large extrusion volume, it also enables high profitability and flexibility. 【Features】 ■ Achieves high product quality as a dedicated machine for temperature and shear-sensitive plastics (such as PVC). *For more details, please refer to the PDF document or feel free to contact us.

The extruder STS Mc from Copelion (made in Nanjing, China) has been upgraded with the addition of STS Mc PLUS. To live up to the name "PLUS," the specifications have also been enhanced. 【Features】 ■ Torque density: 13.6 Nm/cm³ ■ Screw diameter: 50mm to 75mm ■ Screw speed: up to 900 rpm ■ A variety of materials available for barrels/elements, including nitrided steel, high-speed tool steel, corrosion-resistant steel, and wear-resistant steel ■ Equipped with cartridge heaters *For more details, please refer to the PDF document or feel free to contact us.

Stable production, increased output, and product quality (good dispersion) are naturally important points in masterbatch production. Please try the masterbatch-specific twin-screw extruder STS Mc11 series, which pursues a "simple and quick cleaning equipment structure." 【Features】 ■ Easy removal and cleaning with masterbatch-specific die heads (STS 35–65) ■ Ease of cleaning for the raw material hopper and feed barrel ■ Installation of a color to prevent dirt between the vent port and cover ■ Other screw elements and barrels capable of taking in more powder 【Benefits】 ■ Rapid disassembly and cleaning during color changes ■ Reduced production costs due to decreased downtime 【Production Capacity (Examples)】 ■ 30% PE / 20% additives / 50% blue pigment: ~100 kg/h / STS35Mc11, ~560 kg/h / STS65Mc11 ■ PP / 70% TiO2: ~220 kg/h / STS35Mc11, ~1,200 kg/h / STS65Mc11 *For more details, please refer to the PDF document or feel free to contact us.

The "STS Mc11" is an extruder manufactured by Coperion Nanjing, capable of delivering a sufficient torque density of 11.3 Nm/cm³ for general-purpose plastics and engineering plastics compounds. The main component, the reducer, is equipped only with European-made parts, enhancing reliability, including machine precision. 【Features】 ■ Torque density: 11.3 Nm/cm³ ■ Screw diameter: 25 mm to 96 mm ■ Screw speed: up to 900 rpm ■ The materials for the barrel/elements are available in a variety of options, including nitrided steel, high-speed tool steel, and chrome steel. *This catalog is a digest version.

The "STS25Mc11" is a compact, high-torque extruder developed in response to requests from customers in the plastics industry and research institutions. Designed with a focus on compactness and handling, it is well-suited for research applications. It employs a tie rod system for barrel connection, allowing for very quick barrel changes compared to our conventional models. 【Features】 ■ Achieves an extrusion rate of 2 to 80 kg/h ■ Enables precise scaling up to large machines with the same screw inner and outer diameter ratio as conventional models ■ Utilizes a cartridge heater system for uniform heating and energy efficiency ■ Gear reducer and torque limiter are made in Europe ■ Active in research on CNF, bioplastics, and more *For more details, please refer to the materials. Feel free to contact us with any inquiries.

The pioneer of co-rotating twin-screw extruders, Copelion, aims to be a trusted partner for customers worldwide with its extensive process engineering and rich track record (over 15,000 units as of January 2022). ■ Features of ZSK Mc18 Achieves world-class torque level of 18 Nm/cm³, suitable for various applications. ■ Features of STS Mc11 Achieves process technology, torque level, and equipment strength inheriting the Mc designation of ZSK. *Major components (gearbox) are made in Europe.

Leveraging over 65 years of process know-how and technology cultivated in the plastic industry, we will carry out various plastic recycling more efficiently. Mechanical recycling of plastics not only contributes to society but also allows customers to gain greater profits by ensuring that the recycled products hold the same value as the original raw materials, rather than downgrading them. In the increasingly recognized field of chemical recycling, it is possible to perform chemical recycling of waste plastics while considering chlorine countermeasures. 【Examples of Plastic Recycling】 ■ Material recycling including multi-layer films ■ Mechanical recycling of waste plastics considering chlorine countermeasures ■ B to B recycling system for PET certified by FDA/EFSA * For more details, please refer to the PDF materials or feel free to contact us. * You can check the video on material recycling of multi-layer films below.
