In addition to 20 pages of news from the metal and ceramic injection moulding industry, the 72 page March 2010 issue of Powder Injection Moulding International (Vol.4 No.1) includes the following articles and special features:
Multifunctional parts by two-component Powder Injection Moulding (2C-PIM)
The ability to manufacture components in one step using two different materials is opening up a world of opportunities for the powder injection moulding industry.
The possibilities range from combining metals with different properties through to metal/ceramic and ceramic/ceramic components.
Dr. Frank Petzoldt looks at the development of this technology to-date and outlines the challenges that need to considered when planning a two-component PIM part.
Parmaco Metal Injection Molding AG: High tech MIM manufacturing in a Swiss rural retreat
Fischingen, the most southerly community in eastern Switzerland’s Canton Thurgau, nestles in rolling green and wooded hills. The small community is renowned for its former Cistercian monastery and the region, which borders Canton Zürich, is a hikers’ paradise only 40 minutes from Zurich Airport.
Less well known is that Fischingen is the home to Parmaco Metal Injection Molding AG, one of Europe’s leading and most innovative Metal Injection Moulding (MIM) producers since 1992. We report on a recent visit.
PIM in Korea: A review of technology development, production and research activities
Thanks to South Korea’s status as one of the fastest growing economies in the world, the country’s PIM industry has become an important force in both component production and R&D.
Dr. Seong-Jin Park and Dr. Yong-Jin Kim present a review of the development of PIM in this, the largest of Asia’s ‘Tiger’ economies, and profile a number of the leading part producers. The direction of future R&D work is also addressed.
Looking into a MIM furnace: Understanding debinding and sintering using mass spectrometry
By coupling a mass spectrometer to the exhaust system of an industrial scale furnace, researchers have gained a detailed insight into the changes and reactions that take place during the critical debinding and sintering stages of the MIM process. Thomas Hartwig and Renan Schroeder report their initial findings.
Design and Manufacture of Gears with a Skin-Core Structure by Metal Co-Injection Moulding
Hao He, Yimin Li, Pan Liu, Jianguang Zhang
Gears with a skin-core structure have been designed and produced using a novel metal co-injection moulding technique.
The effect of skin temperature and injection velocity on the material distribution of the co-injection moulded specimens has been studied.
A Case Study on Computational Fluid Dynamics Analysis of Micro-MIM Products
Ian Andrews, Kazuaki Nishiyabu and Shigeo Tanaka
Many people are familiar with computational fluid dynamics studies for plastic injection moulded parts but little study has been undertaken in the field of micro metal injection moulded parts.
Micro metal injection moulding (MIM) is a relatively new technology and many advances are progressing in production methods that increase accuracy and applicability of its use. Computational fluid dynamics studies of such methods can assist in furthering the advancement of this technology and can provide valuable information to manufacturers and consumers alike.
Influence of Particle Size Distribution and Chemical Composition of the Powder on Final Properties of Inconel 718 Fabricated by Metal Injection Moulding (MIM)
J. M. Contreras, A. Jiménez-Morales and J. M. Torralba
Inconel 718 is one of the most common Ni-base superalloys due to its large number of engineering applications in automotive, chemical, aerospace and energy generation industries.
The aim of this work is to study the influence of the particle size distribution along with the chemical composition of different Inconel 718 powders on the final properties of components fabricated by Metal Injection Moulding (MIM).
