This work has been motivated by some issues of process monitoring in casting applications. In die casting, as time passes, material is deposited on the inside wall of the die. This foreign material can cause an unacceptable level of porosity in the output of the casting process. After accumulated material reaches a certain level, some of the output of the casting process no longer meets the spe...

The article presents the application of total productive maintenance (TPM) to analyze the working time indicators of casting machines with particular emphasis on failures and unplanned downtime to reduce the proportion of emergency operation for preventive maintenance and diagnostics. The article presents that the influence of individual factors of complex machinery maintenance (TPM) is ...

The effect of squeeze casting process parameters on wear behavior of AC2A aluminium alloy was primarily investigated in this experimental study. Five process parameters, namely squeeze pressure, pouring temperature, die temperature, die material and compression time, each at four levels were chosen and sixteen experimental runs based on L16 orthogonal array were performed. From analysis of vari...

The paper presents the analysis of thermo-mechanical fatigue cracking of die casting die during industrial use. An innovative, production friendly approach to monitor the surface crack dimensions was introduced, which is based on measuring defect-fi n on the casting part. A new four moulds die casting die was monitored 40 000 cycles in order to complete the production series. The production was...

The present work analyses different parameters of pressure die casting to minimize the casting defects. Pressure diecasting is usually applied for casting of aluminium alloys. Good surface finish with required tolerances and dimensional accuracy can be achieved by optimization of controllable process parameters such as solidification time, molten temperature, filling time, injection pressure an...

In the die casting or permanent mold casting process, proper control of temperature is essential for producing high quality parts and yielding high production rates. In particular, defects can be caused by the uneven cooling of a casting during solidification. In this paper, two standard silicon-based charge coupled device (CCD) cameras are used to localize the position of the die, and measure ...

version on a funder's repository at a funder's request, provided it is not made publicly available until 12 months after publication. High-pressure die casting is the preferred process for manufacturing Mg-alloy components used for numerous applications. High-pressure die casting is suitable for mass production and has the advantage of also being suitable for accurately fashioning objects of co...

important activities of die-casting die design. In normal practice, determine therunner and gating designparameters. These parameters are simulations on a computer and dry runs on adie-casting machine These iterative activities increase the manufacturing lead time and makes A system which could reduce the iterations and make the presentsa computer-aided system for runner and gating system gener...

In today’s world a casting production without any defect is almost impossible. After the application of various optimization techniques and process we still are not able to get the defect free castings. So it is critically important to analyze the root cause of casting defect with in the process itself, so that any changes which can hamper the defect intensity can be invoked at the time of manu...

Primljeno (Received): 2011-11-07 Prihvaćeno (Accepted): 2012-03-15 Original scientific paper Abstract: Pressure die casting is the method used for forcing molten metal into mould cavities under high pressure and at high speed (10 100 m.s). Pressure die casting is a highly productive method of casting parts with low dimensions tolerance and high surface quality. From the point of view of product...
