Element 22: A leader in titanium MIM leverages its expertise to advance sinter-based Ti Additive Manufacturing
The production of titanium components by powder-based processes requires specialist knowledge and in-depth expertise in the handling and, in particular, the debinding and sintering of this highly reactive metal.
Element 22 GmbH is a global leader in the Metal Injection Moulding of titanium and its alloys, and a growing focus of the company’s development activities is sinter-based Additive Manufacturing.
Dr Georg Schlieper visited the company on behalf of PIM International and reports on the current state of production and the company’s future ambitions.
Digitising part production:
A new approach to creating unique part IDs for MIM components
Terms such as Industry 4.0 and the Digital Twin trace back to the growing trend to digitise industrial processes. Modern production equipment delivers a huge quantity of process data, and the continuous analysis and correlation of these data could result in process stability improvements, less scrap and enhanced traceability. For such advances to be applied to MIM production, the permanent surface marking of each part with a unique ID is required.
In this article, Prof Dr-Ing Frank Petzoldt and Lutz Kramer, from Fraunhofer IFAM, Bremen, Germany, report on the development of a process that offers a cost-effective solution to what currently poses a significant technical challenge.
Making the business case:
How sinter-based Additive Manufacturing can compete with Powder Injection Moulding
When it comes to closely related manufacturing processes such as Powder Injection Moulding (PIM) and sinter-based Additive Manufacturing, the ability to design a part that could be produced by either process has numerous advantages.
Loran Mak, from AM machine developer Admatec Europe, and Harrie Sneijers, from sister company and PIM specialist Formatec Technical Ceramics B.V., present an overview of Vat Photopolymerisation (VPP) and PIM technologies and, through two case studies, highlight how the advantages of the processes can be leveraged when making the business case for each application.
Reducing MIM part costs with more expensive materials?
The re-evaluation of a major 3C application
Metal Injection Moulding is today widely used for the manufacture of 3C components, with 17-4PH and 316L stainless steels dominating production. Other material choices exist, however, that may be better suited to a new generation of 3C applications. In this study by Shin Lee, Chung-Huei Chueh and I-Shiuan Chen, Chenming Electronic Technology Corp. (UNEEC), evaluate Co-Cr-Mo alloy (F75) and X15 CrMnMoN 17-11-3 (known as P.A.N.A.C.E.A. by Catamold® users) as an alternative to 17-4PH.
Mechanical strength, magnetic properties, corrosion resistance, wear resistance and total cost, based on a major 3C application, are compared. Whilst the conclusions of this study may not be fully applicable to all MIM applications, they provide appropriate directions for MIM end-users and manufacturers to pursue.
The production and evaluation of alumina sinter supports for Metal Injection Moulding by ceramic Additive Manufacturing
In this article, Dr Samuel von Karsa-Wilberforce, Emery Oleochemicals GmbH, Germany, and co-authors report on the production and evaluation of sinter supports for Metal Injection Moulding produced by the Additive Manufacturing of highly filled alumina feedstock filaments.
The alumina filaments are based on Emery Oleochemicals’ established PIM binder system and processed by Material Extrusion (MEX). Partners in the study include CMG Technologies, UK, 3DGence Sp. z o.o, Poland, Spectrum Filaments, Poland, SiCeram GmbH, Germany, and Ingenieur-Buero Jaeckel, Germany.
