SAT-X is multifunctional. With a more powerful gearbox, more precise screw elements, SAT is endowed with a more flexible processing range and wider operation window. We also provide individual solutions according to customized requirements. With a variety of modular screw elements, barrels, melt filtration and pelletizing system, we will promise you a worthy investment.
With 13Nm/cm3 specific torque, it can perform greater delicate processing tasks and precise process control to meet complicate and sophisticate processing purpose. Better dispersion, more accurate temperature control and higher throughput have been integrated and optimized further in this extruder.
SAT-X twin screw extruder meets the mainstream European standards, meaning that SAT-X compounder can work under lower temperatures with higher throughput.
Plastics compounding plays a role in all facets of modern life. Twin screw extruders are available for research and development purposes to process as little as a 50-gram batch, and for full-scale production at rates of 50,000+ kgs/hr. The attributes inherent with a twin screw extruder makes it the preferred manufacturing methodology for the continuous mixing of commodity and high-tech precision products.
Twin screw extruders componentry and operation are well understood, and have proven for 100 or so years in a myriad of 24-hr industrial settings (pellets and parts). That being said, a twin screw extruder is unlike a washing machine in that a variety of techniques must be integrated and applied to successfully mix a multi-component formulation.
A basic understanding about the interrelationships of the output rate/screws rpm, screw design and elements and viscosity management allows the user to troubleshoot a TSE process to achieve a high-quality, homogenous melt without degradation. A quick summary on these parameters includes:
For good plasticizing effect,we have different designs of screw and barrel for extruder or injection to meet customer"s demand.Our factory manufactures with high-quality material, applying the method of hardening and tempering and nitriding, thus it enjoys the characteristics of long working life, wear resistance, and anti corrosion. Besides, the technique of hard alloy spraying or chrome plating can be used on the working surface of screw, which will make it have better using effectiveness.
We are the first screw element manufacturer in China, with more than 20 years" manufacturing experience, our screw element,barrel, shaft are produced by HIP material import from Germany to be same anti-wear& anti-corrosion , our customer including Europe extruder manufacturers, and world’s leading polymer compounders like Aschulman,Polyone,Covestro,DSM enginering plastic ,Lanxess.

ZSK twin screw extruders can be highly productive even in difficult applications with aggressive products. We provide the proof of our extensive experience in the development and application of extremely wear and corrosion resistant material solutions: Considering your individual requirements, our experts help you to determine the exact combination out of more than 150 materials to ensure highest durability and reliability of the wear parts especially with economical considerations. This applies to all parts when purchasing a new ZSK extruder as well as to our comprehensive spare parts service.
C-Rock is characterized by its highly wear and corrosion resistant matrix with specially selected hard material components. It is applied to product-contact parts of the ZSK extruder barrels using a technologically advanced manufacturing process. The result is a completely homogeneous, closed surface screw channel and first-class adhesion of C-Rock to the base material.
C-Rock gives the highest protection against abrasion and corrosion to the barrels of Coperion ZSK extruders. It allows for highest productivity even in difficult applications with aggressive products and extends the life of the barrels.
The wear material C-Rock is particularly suitable for compounding PA, PBT, PP, HT plastics with glass and carbon fibers, ceramic masses, metal masses and powders. We recommend C-Rock for extruder barrels in the melting, mixing and pressure build-up zones of the process section.
Among other methods, twin screw wet granulation (TSWG) is the most appropriate imminent continuous unit operation for the pharmaceutical manufacturing industry efficient enough to produce granules using reduced granulating fluid quantity as compared to traditional mixer granulators with the added advantage of consistency, better control over its stability, minimum residence time, controlled output, and more adaptable to in-line analytical tools. TSWG could substitute the current techniques for batch granulation, making the granulation process more versatile, reproducible, and cost-effective. In this twin screw granulation technique, raw material input enters the equipment where the blend is conveyed through the barrel. Granulation of raw material blend takes place because of granulating solvent like water or binder solution. Use of specific screw elements like kneading blocks and distributive elements allows agglomeration as well as the milling of the granules along the length of the barrel. Use of minimum quantity of solvent means wet granules can be dried within the barrel length using barrel temperature and thus additional drying step is circumvented. The various factors that affect the final granule quality that acts as critical quality attributes for the TSWG process include feed rate, liquid to solid (L/S) ratio, barrel fill volumes, processing temperatures, and screw elements (17, 27, 31, 35, 50, 100–103).
Dhenge et al. (2011) investigated the effect of varying feed rates from 2 to 6 kg/h on the residence time and properties of TSWG granules while maintaining other variables such as the liquid to solid ratio (0.3), screw design (two kneading zones), screw speed (400 rpm), and barrel temperature (25 °C). A nonfunctional API (sodium chloride) was combined with a solid binder (hydroxypropyl cellulose) at a concentration of 5%. The granulating agent was water. Feed rates were found to be inversely proportional to residence time distributions, owing primarily to barrel fill stage. However, the findings indicated that increasing the feed rate resulted in a greater concentration of fines of good strength. This is primarily due to material cramming caused by high feed rates and short residence times, which results in increased attrition between the wet mass and the screws and barrel. Thus, this article emphasizes the importance of feed rate on granule efficiency (104).
Portier et al. explored the effects of screw configurations (kneading elements thickness and fraction of KE elements), barrel fill levels (screw speed), and L/S ratios on model formulations using microcrystalline cellulose (MCC) and lactose monohydrate (LM) as diluents, HPMC as the dry binder, and metformin hydrochloride and mebendazole as model APIs.
