Development and Validation using Casting Simulation of a Multi-point Remote Monitoring System for High-Pressure Die-Casting (HPDC) Mold Cavity

Development and Validation using Casting Simulation of a Multi-point Remote Monitoring System for High-Pressure Die-Casting (HPDC) Mold Cavity

Abstract This research presents the design and implementation process of a remote monitoring system for temperature and force-induced pressure measurements in the mold cavity of high-pressure die casting (HPDC). A K-type thermocouple sensor was chosen to gauge the aggressive environment inside the mold cavity. An ejector pin was adapted for the installation of this sensor,

Figure 3. Radio filter produced by means of the RSF/RheoMetalTM process. A unique feature of this product is the weight reduction of 1.6 kg facilitated by wall thicknesses as low as 0.4 mm at 40 mm height (aspect ratio 100). High conductivity low Si alloys were used, and thermal transport properties further increased by up to 20% depending on the alloy composition by means of heat treatments, as depicted in the top right diagram by means of arrows denoting the course of the latter (images provided by Comptech AB, Skillingaryd, Sweden).

Strength of Salt Core Composed of Alkali Carbonate and Alkali Chloride Mixtures Made by Casting Technique

Jun Yaokawa, Daisuke Miura, Koichi Anzai, Youji Yamada, Hiroshi Yoshii Abstract The strength of four binary systems NaCl–Na2CO3, KCl–K2CO3, KCl–NaCl and K2CO3–Na2CO3 was investigated in order to develop expendable salt core for high pressure die casting processes. Four point bending test was conducted to determine the strength of specimens made from molten salts by using the permanent mold casting technique.

Die casting is mostly used because many parts need to be manufactured in a short amount of time (hundreds to thousands per day) with high accuracy. Parts like valve covers, wheels, transmission housings, engine block, wheel spacer, carburetor, impellers and fan clutch, alternator housing, airbag gas generator housing, etc. are all modes through the aluminum die casting method. Automobile parts require uniformity and high surface finish which can be accomplished by using casting methods that work in a controlled environment- pressure dies casting. Die casting was originally developed specifically for automotive applications [28]. The idea is to produce parts that are light, easy to handle, and cheap. Thus, die casting is widely applied to zinc and aluminum which are lighter than cast iron. Figure 2 shows the aluminum die-cast parts of a car. PEGASUS has been supplying quality aluminum die-cast auto parts to the automobile industry with our stable production system since we started this business in 2007 [27]. At present, we are supplying 60 kinds of die-cast products with our unique mold design and casting technology in addition to the processing technology we have been cultivating in the industrial sewing machine industry [29]. Aluminum or Al-Si alloys are used for Die casting. During this process, molten metal is injected at high pressure into a die (made of metal) which is a permanent mold comprising of two parts of the desired shape attached [30].
