Whaley 5.0 out of 5 stars Its only shortcoming--if you care to call it that--is its reliance on the most common thermoplastics to describe all plastics extrusion. In defense of the authors, they did state that caveat. I have given it 5 stars but I only studied about half of the material in the book, and do not feel qualified to rate the other half, specifically the chapters around heat transfer, downstream equipment, design and integration, computer control, and plant design. Someone with more experience around that might give the prospective buyer a better picture.

6 The main difference between both systems is the type of deformation applied on the molten material coming out of the die. The deformation is uniaxial in calendering and biaxial in blowing... 27,30,31 Table 5 shows that the foamed film's apparent density ranges between 1.00 g cm A3 and 1.18 g cm A3 being within the density range of most synthetic polymers used for packaging (0.9-1.3 g cm A3 ). 2, 6 This suggests that these foamed films have the potential to be used as raw materials for this application. Some correlations between the apparent density and the distribution of the cells or voids within the films are expected... On the other hand, the samples are only uniaxially stretched by two rolls in calendering, resulting in foamed films with higher thickness. 6 This is why the foamed films with lower thickness have a higher orientation level which contributed to lower elongation at break than the ones with higher thickness, since the molecules are already more stretched. The comparison between samples made by blowing (M7A to M9A) versus calendering with the same formulations gives higher values by 59 (M1A), 207 (M2A), and 70 (M3A) in their strain at break ( Figure 5).. Production and characterization of fully biobased foamed films based on gelatin Article Jan 2020 CELL POLYM Javier Solorza-Feria Maria alejandra Ortiz-Zarama Antonio Ruperto Jimenez-Aparicio Denis Rodrigue The objective of this study was to produce and characterize gelatin foamed films using extrusion. Furthermore, the three “optimum” formulations were produced by extrusion film blowing only, since no stable processing conditions could be obtained for the controls. A complete set of sample characterization was performed, including morphological, mechanical, physical, and thermal properties.
The results showed that besides the processing method, the thickness was also controlled by the glycerol and water content, leading to density slightly above unity, with higher values for the optimum materials. The calendered films from the optimum formulations showed overall a higher number of cells and cell density than the controls. Higher elastic moduli and tensile strengths were obtained for the films from the optimum formulations made by either method because of the reinforcing effect of the tannic acid and nanoclays, but this led to lower strain at break. The thermal profiles were similar for all films, with higher stability for the optimum formulations. The results were also explained via chemical interactions between the components as observed by Fourier transform infrared spectroscopy. Overall, the optimum formulations not only produced better foamed films in terms of general properties but were much easier to process by both methods (calendering and blowing). View Show abstract. In other words, the structural integrity of the part is compromised if high amounts of residual stresses are induced during 3D-printing. Increased levels of crystallinity result in higher shrinkage and therefore an increase in warpage and residual stresses in the part.. Prediction of part distortion in Fused Deposition Modelling (FDM) of semi-crystalline polymers via COMSOL: Effect of printing conditions Article May 2021 Anto Antony Samy Atefeh Golbang Eileen Harkin-Jones Alistair McIlhagger Residual stresses and warpage adversely affect the dimensional accuracy and performance of 3D-printed semi-crystalline polymers in Fused Deposition Modelling (FDM). One of the main challenges in FDM is to understand and relate the impact of printing conditions on part distortion for optimizing the 3D-printing process to achieve good print quality.
Hence, the effect of various printing parameters, particularly print bed temperature, layer bonding, layer thickness and raster pattern, on built-up residual stresses and warpage is simulated in this work, by building a relationship between the crystallisation kinetics, viscoelastic and thermo-mechanical properties of the polymer in relation to changes in temperature during FDM using element activation in COMSOL. To the best of our knowledge, this is a novel approach for quantitative prediction of part distortion in FDM of semi-crystalline polymers under various printing conditions. Based on the simulation results, it is observed that a decrease in layer thickness from 0.5 mm to 0.1 mm results in an 89 drop in warpage and a reduction in residual stress of 24. Applying a line raster pattern reduces warpage and residual stresses by 16 and 36, respectively in comparison with a zigzag raster pattern. Very good agreement is observed between simulation and experimental results for warpage under various printing conditions. Moreover, due to the complexity of the extrusion head, another non-ontological resource was used as a reference to represent the features of this component... We did not find any ontological resource that defines the specific types of sensors that are used to monitor extruders. ExtruOnt: An ontology for describing a type of manufacturing machine for Industry 4.0 systems Article May 2020 Victor Julio Ramirez-Duran Idoia Berges Arantza Illarramendi Semantically rich descriptions of manufacturing machines, offered in a machine-interpretable code, can provide interesting benefits in Industry 4.0 scenarios. However, the lack of that type of descriptions is evident. In this paper we present the development effort made to build an ontology, called ExtruOnt, for describing a type of manufacturing machine, more precisely, a type that performs an extrusion process (extruder).
Although the scope of the ontology is restricted to a concrete domain, it could be used as a model for the development of other ontologies for describing manufacturing machines in Industry 4.0 scenarios. The terms of the ExtruOnt ontology provide different types of information related with an extruder, which are reflected in distinct modules that constitute the ontology. Thus, it contains classes and properties for expressing descriptions about components of an extruder, spatial connections, features, and 3D representations of those components, and finally the sensors used to capture indicators about the performance of this type of machine. The ontology development process has been carried out in close collaboration with domain experts. The screw material was AISI 4140, which was treated with flame hardening to obtain 55 HRC hardness. The screw dimension related to the equation is described in Figure 3 and Table 2... The volume of melt entering the melt pool was calculated from the output according to Equation (1). The extruder delivers a plastic melt to an impregnation die in sufficient volume and is pulled out along with the fibers. The fibers pass in a sideways stretched condition through spreader pins attached in the melt pool, which can then be wetted optimally. The wetting effect was also improved by immersing fiber in a coupling agent solution at an elevated temperature before feeding to the extruder die. Scanning electron microscopy (SEM) was applied to characterize the quality of fiber impregnation. SEM characterized a good bonding performance between carbon fiber and the matrix. Multilayer membranes were prepared using the three-stage Melt-Extrusion, Annealing and Uniaxial Stretching (MEAUS) process. The orientation of PP’s crystalline phase was affected by both the flow-induced crystallization and the heterogeneous nucleation promoted by the fillers.
A synergistic effect was observed in the filled samples due to the generation of pores after the stretching-induced lamellae separation and the debonding of mineral fillers from the polymeric matrix. The fillers increased the porous surface, leading to an increase of permeance to air, being this effect more marked at higher filler contents. Talc showed a higher efficiency to create porous surfaces when compared to calcium carbonate. The thermal stability of the membranes increased with filler addition, as well as their stiffness and strength. Owing to this feature, complete emptying of the material from the extruder is possible, thus reducing the wastage of product during the manufacturing process. Prime importance should be given to study the formulation as well as process parameters to meet requirements. By modifying the equipment design and varying a few processing conditions, a myriad of different dosage forms for various applications can be developed. In-depth pre-formulation research is required for the rational selection of an active pharmaceutical ingredient, carrier, and additives for the smooth and continuous functioning of the HME process to achieve the desired product. This review channels to a holistic perspective of several equipment components, processing requirements, materials used in HME, and various drug delivery systems utilizing HME in recent years. It gives a comprehensive treatise on several novel opportunities and innovations such as three-dimensional printed dosage forms, abuse-deterrent formulations, co-extrusion, chronotherapeutic drug delivery, co-crystals, nanotechnology, semi-solids, twin-screw granulation, and miscellaneous applications. The progress described herein may also flourish the drug delivery scenario in the veterinary clinics by employing HME technology, which is briefly discussed in this review for the first time.
The article also highlights a brief insight into the global status of the pharmaceutical HME market during the period between 2016 and 2024. Lattermost, this review summarizes several applications of HME over the recent four years in drug delivery in a tabular form for ease of readers. Overall, this article is an attempt to lay a bibliographic foundation for formulator scientists working in this area and promote further investigations in this field. This material can also be co-extruded simultaneously with other materials like PVC to achieve both a robust and soft part. Maraging steel Ni-18 (M300) die were produced by Selective Laser Melting (SLM) using AM125 machine provided by Renishaw. The developed and manufactured extrusion die has not been processed by finishing the process, i.e. grinding, polishing or sandblasting. The tests were carried out using TPE industrial extrusion plant. Moreover, designed extrusion die to decrease weight and save the material; the design was hollow. The presented results indicate that the SLM technique is a promising method for the production in one production process the extrusion dies used in the TPE extrusion process with complex internal walls, with high accuracy, high speed and at low costs and own outlays. Moreover, this technique gives the constructors possibilities to design very complicated shapes of profiles with more than one of the working areas (bubbles) or design co-extrusion dies. Application of SLM technique allows to manufacture air ducts with pipe connectors to fasten an air, hence eliminating from the process expensive and time-consuming electrical discharge machining. Here full factorial DOE analysis is carried out, with two levels each against the six design parameters as discussed earlier..
