Integrating Cold Forging and Progressive Stamping for Cost
Precision Cold Forging Progressive Stamping Enables Cost Effective Production of Complex Parts Overview Both Cold Forging and Precision Stamping are proven technologies used in the fabrication of parts for a wide range of industries. Many of our previous Tech Bulletins have detailed the benefits of each technology, and in several cases, these processes are thought of as an either- or choice. This Tech Bulletin provides insights into how combining these technologies in a process known as Precision Cold Forging Progressive Stamping can provide significant synergies and additional benefits for the cost-effective production of complex parts that cannot easily be created by either technique alone. What is Cold Forging? As detailed in other Interplex Tech Bulletins, Cold Forging is essentially an impact forming process in which billets of raw material are compressed and reformed into a part’s desired shape. Cold Forging offers the key benefits of lower costs, rapid high-volume throughput, high part strength, and very efficient material utilization. This, in comparison to processes like machining that remove Figure 1 – Cold Forged significant amounts of raw material rather than simply reforming all the Automotive Seat Belt Gear material into the desired shape. What is Precision Stamping? Precision Stamping is another proven technology that uses a press and die to form sheet metal, blanks or coil material into desired shapes. Variations of the stamping process can effectively yield several different output results including bending, embossing, flanging, coining, etc. Like Cold Forging, Precision Stamping typically offers high material utilization with minimal waste and can also deliver high-volume production results. -

This is particularly true in the automotive industry, where manufacturers are obliged to develop advanced techniques to reduce the pollution by reducing the fuel con- sumption without significant increase in the cost. Among all the manufacturing techniques, the stamping and hydroforming methods hold a top position among the cold sheet metal forming processes due to the versatility of components that can be produced and high production rates [1]. Stamping and hydroforming processes are intensively used in various industrial sectors such as transportation, car body in white (Figure 1.1), household appliances, metal packaging, etc. The use of fluid pressure has been remarkably increased in sheet metal form- ing processes since it allows a superior final surface quality of the workpiece than standard deep drawing process [2–4]. In particular, sheet hydroforming process has great potential to manufacture body-in-white parts with consistently extreme level of ultimate tensile strength, reduced weight, geometrical accuracy, and minimum tol- erances. It has certain advantages, e.g. more uniform thickness distribution of the final workpiece component, lower tooling cost, and versatility to produce partswith different geometries using the same setup [5]. The worldwide acknowledgment of these two sheet metal forming processes is largely due to the external pressure from the government legislators to develop lightweight products. -

A Comparison of Thixocasting and Rheocasting
A Comparison of Thixocasting and Rheocasting Stephen P. Midson The Midson Group, Inc. Denver, Colorado USA Andrew Jackson Arthur Jackson & Co., Ltd. Brighouse UK Abstract The first semi-solid casting process to be commercialized was thixocasting, where a pre-cast billet is re-heated to the semi-solid solid casting temperature. Advantages of thixocasting include the production of high quality components, while the main disadvantage is the higher cost associated with the production of the pre-cast billets. Commercial pressures have driven casters to examine a different approach to semi-solid casting, where the semi-solid slurry is generated directly from the liquid adjacent to a die casting machine. These processes are collectively referred to as rheocasting, and there are currently at least 15 rheocasting processes either in commercial production or under development around the world. This paper will describe technical aspects of both thixocasting and rheocasting, comparing the procedures used to generate the globular, semi-solid slurry. Two rheocasting processes will be examined in detail, one involved in the production of high integrity properties, while the other is focusing on reducing the porosity content of conventional die castings. Key Words Semi-solid casting, thixocasting, rheocasting, aluminum alloys 22 / 1 Introduction Semi-solid casting is a modified die casting process that reduces or eliminates the porosity present in most die castings [1] . Rather than using liquid metal as the feed material, semi-solid processing uses a higher viscosity feed material that is partially solid and partially liquid. The high viscosity of the semi-solid metal, along with the use of controlled die filling conditions, ensures that the semi-solid metal fills the die in a non-turbulent manner so that harmful gas porosity can be essentially eliminated. -

processes Review Methods Used for the Compaction and Molding of Ceramic Matrix Composites Reinforced with Carbon Nanotubes Valerii P. Meshalkin and Alexey V. Belyakov * Mendeleev University of Chemical Technology of Russia (MUCTR), 9 Miusskaya Square, 125047 Moscow, Russia; [email protected] * Correspondence: [email protected]; Tel.: +7-495-4953866 Received: 2 August 2020; Accepted: 11 August 2020; Published: 18 August 2020 Abstract: Ceramic matrix composites reinforced with carbon nanotubes are becoming increasingly popular in industry due to their astonishing mechanical properties and taking into account the fact that advanced production technologies make carbon nanotubes increasingly affordable. In the present paper, the most convenient contemporary methods used for the compaction of molding masses composed of either technical ceramics or ceramic matrix composites reinforced with carbon nanotubes are surveyed. This stage that precedes debinding and sintering plays the key role in getting pore-free equal-density ceramics at the scale of mass production. The methods include: compaction in sealed and collector molds, cold isostatic and quasi-isostatic compaction; dynamic compaction methods, such as magnetic pulse, vibration, and ultrasonic compaction; extrusion, stamping, and injection; casting from aqueous and non-aqueous slips; tape and gel casting. Capabilities of mold-free approaches to produce precisely shaped ceramic bodies are also critically analyzed, including green ceramic machining and additive manufacturing technologies. Keywords: carbon nanotubes; ceramic matrix composites; compaction; molding; casting; powder mixtures; green bodies; plastic molding powders; slips; polymerizable monomers; solid freeform fabrication; machinery 1. Introduction Compaction molding is an important technological stage in the mass production of technical ceramics and ceramic matrix composites (hereinafter, CMCs). -

The article is devoted to the theoretical study and development of the production process of manufacturing rod products with larger heads by transverse extrusion. For carrying out researches the elastic-plastic finite- element model based on the variation principle was chosen. This model, due to the development of a complex of boundary and initial conditions, has been adapted to the scheme of volume stamping of the fasteners and implemented in the form of a software package in the system DEFORM 3D.The paper presents the results of computer simulation of the technology of manufacturing the mortgage bolt 1 Introduction With the development of mechanical engineering, automotive and construction, there is a growing need for sophisticated modern fasteners which allows you to create strong, high- performance, reliable and durable connections. These fasteners contain: flanged fasteners, self-drilling and self-tapping screws, their use greatly simplifies and speed up installation work [1]. Fig. 1. Items with long cone and an enlarged head.
