15th birthday of STS Extruders: Coperion adds new laboratory extruder to the STS Series

The STS twin screw extruder from Coperion is celebrating its 15th birthday this year. Thanks to the ongoing technological and design development, the STS extruder has proven itself today as a strong performing quality product for numerous compounding processes on the market.

The new STS 25 Mc¹¹ laboratory extruder

Just in time for this anniversary, Coperion has expanded the STS series by one more extruder size: The new STS 25 Mc11 extruder with a 25 mm screw diameter is designed especially for research and development tasks as well as for production of small batch sizes of 2 kg and more, achieving throughputs of up to 90 kg/h. It will be shown for the first time at Chinaplas 2019 (21-24 May 2019, Guangzhou, China) at the Coperion booth 5.1M11 in Hall 5.1.

STS Extruder Now in Laboratory Size

Completely new and available to view for the first time at this year's Chinaplas is Coperion's STS 25 Mc11 extruder with a 25 mm screw diameter. It boasts all the advantages of the STS Mc11 series, has a simple design, is operator-friendly and easy to clean. Its feed barrel is equipped with an exchangeable sleeve insert to facilitate cleaning. In addition the die head is in quick-release design for easy operation and accelerates product changes again. The base frame has a closed, simple to clean surface and is equipped with castors for easy movement of the extruder and fast installation. Water cooling, vacuum unit and air supply can be integrated into the base frame as an option. For maximum efficiency and energy savings Coperion has equipped the new STS 25 Mc11 extruder with cartridge heaters for precise single zone tempering of each individual barrel. By having the same screw diameter ratio Do/Di (outer screw diameter to inner screw diameter) of 1.55 and the same maximum specific torque Md/a³ of 11.3 Nm/cm³ as the whole STS Mc11 extruder series, production parameters of the STS 25 Mc11 can be reliably scaled up to larger STS sizes which makes it the ideal compounding system for recipe development and basic scientific research. The STS 25 Mc11 which Coperion will exhibit at Chinaplas will be shown with the highly accurate Coperion K-Tron twin screw feeder K-ML-SFS-KT20.

15 Years of the STS Twin Screw Extruder

15 years after its introduction, the STS systems from Coperion serve as reliable high-performance extruders for a variety of applications, primarily in plastics compounding. When the first model of this extruder type was delivered in 2004, the STS twin screw extruder was equipped with a torque of 8.7 Nm/cm³ and achieved screw speeds of up to 600 min-1. Throughput was limited to 1,200 kg/h with the then-largest machine size, the STS 75 with a 75 mm screw diameter. At that point, rapid development of the STS extruder series' technology, design and quality followed which was barely imaginable for the time. In 2008, the STS advanced with specific torque of 10 Nm/cm³ and screw speeds up to 800 min-1 launched successfully. Today's high-performance, high-quality STS Mc11 was introduced to the market in 2015 and has set new standards. It has a maximum specific torque of 11.3 Nm/cm³ and screw speeds of up to 900 min-1. In its largest extruder size, the STS 96 Mc11, today throughputs of up to 4,200 kg/h are achieved. Screw elements and barrels are available in various materials from standard versions to highly wear and corrosion resistant solutions, individually tailored to applications' requirements and high throughput rates. The screw diameter ratio Do/Di of the STS extruder is 1.55, which is the same ratio that Coperion uses for numerous ZSK extruders and that has proven itself for an optimal combination for most plastics processing applications. The STS Mc11 extruder is equipped exclusively with high-quality Coperion-brand gearboxes manufactured in Europe. STS Mc11 is produced at Coperion in Nanjing, China, in accordance with CE guidelines and the highest Coperion standards of quality, and is distinguished by its very attractive price-to-performance ratio. Originally the STS extruder was mainly applied for the modification of engineering plastics and masterbatch. After 15 years of continuous process technology development, today the STS extruder series proves itself successful in compounding of engineering plastics, masterbatch, powder coating, cable masses, recycled plastics, regrind and much more. From 2004 to 2018 700 STS extruders have been installed all over the world, achieving Coperion's historical record with over 100 STS extruders sold in 2018.

Highest Quality Standards in STS Production

The incomparable development of the STS extruder series to become a best quality high-performance extruder was made possible in part by implementing strict manufacturing controls at Coperion's Nanjing location over the last few years. Coperion Nanjing uses German machining centers with state-of-the-art technology and has long implemented proven Coperion standards to ensure high-quality production. The manufacturing process is closely supervised using highly accurate, complex German machines and equipment components for production and quality measurement. The Coperion factory in Nanjing, meanwhile, is now delivering the same high standards of quality for which Coperion Stuttgart is known.

Brazilian market for plastics machinery

Brazil is Europe's most important trading partner in Latin America. In 2018 the export of plastics and rubber machinery from the EU to Brazil amounted to 169 Million Euro. Reason enough to have a close look on the Brazilian Market for Plastics Machinery. This is why EUROMAP, in cooperation with the Gesellschaft zur Förderung des Maschinenbaues, gave MaxiQuim, the largest Brazilian consulting company for the chemical industry, the order, to analyse the current machine installations and to evaluate the prospects for the future. As a first market segment, the Brazilian packaging industry was analysed. Therefore, MaxiQuim interviewed 75 companies producing consumption and industrial packages. The market is dominated by smaller companies with up to 100 employees and a capacity below 5000 kton of processed material per year. With an average age of 10 years of the machines, the situation in Brazil is similar to Europe. The economic recession in recent years has affected investments and the machine utilization rate was relatively low (average 75%). However, 40% of the companies plan investments in the next 5 years, partly more than 1 Million Euros. For injection moulding higher investments are expected than for extrusion. In total, future investments depend on an effective resumption of the machine utilization rate. Higher value-added products such as multi-layer flexible packaging are identified as a future trend. As consequence, the quality of the machine has been mentioned a most important purchasing factor, followed by the price. Although an increasing level of automation and productivity is requested, Industry 4.0 (smart factory) has not really reached Brazil yet. EUROMAP plans to conduct following studies for updating the figures and findings and for regarding other segments like automotive.

Zero cooling technology from Nissei ASB

Japanese company Nissei ASB Machine Co Ltd (ASB) (Hall 11.1 Booth R21) will be exhibiting for the first time at Chinaplas its new and innovative Zero Cooling technology. The company says that developments introduced in this new series enable significantly faster moulding cycles, along with improved product quality.

The reduced injection cycle times are made possible by ASB's proprietary four-station, one-step moulding methodology, which allows virtually all preform cooling to be moved away from the injection station and into the second, conditioning station. The Zero Cooling moulding method eliminates any need for thin, non-optimised preforms, which are susceptible to several quality related problems such as “fisheye”, “body ring” and “orange peel”. This means that designers can create shorter preform designs with thicker wall sections, thus enabling the optimisation of stretch ratios, improved quality and increased productivity. ASB says that there is no need to conform to the traditional need to compromise between cycle time and container quality.

The new, advanced cooling method also permits moulding of heavyweight premium cosmetic containers in very short cycle times, without haziness, using standard PET grades.

The latest version of the mid-range ASB-70DPH one-step injection stretch blow-moulding machine will be demonstrated for the first time. Regular technology updates have kept it at the forefront of its class, in terms of efficiency and productivity.

The version being shown at Chinaplas, a pre-production model of the next generation, will showcase a range of updates and options that improve flexibility and productivity, especially for smaller containers.

Among the improvements are: a revised clamping hydraulic circuit; adjustable stroke in all clamping stations; and adjustable daylight, which allows for longer preforms. A fully-revised blow station is claimed to cut index time, simplify mould changeover and reduce maintenance. The new model is compatible with existing ASB-70DPH moulds. ASB says that these features cut indexing time 40%. A 30 ml container using a short preform can be moulded up to 2.2 seconds faster; this is in addition to reduced cycle time obtained from the use of Zero Cooling technology.

The new technologies will be joined on ASB's stand by a range of sample packaging technologies and a full line of ancillary equipment.
