Since zinc die casting’s conception over 100 years ago, many new and improved developments have taken place to progress the industry and offer component designers a costeffective alternative to higher priced alloys and processes. The zinc industry has continued to develop new alloys in response to some of the challenges that face it. One such development is EZACTM, Eastern Alloys’ high strength...

BACKGROUND Conventional investing and casting techniques are time-consuming and usually requires 2-4 h for completion. Accelerated nonstandard, casting techniques have been reported to achieve similar quality results in significantly less time, namely, in 30-40 min. During casting, it is essential to achieve compensation for the shrinkage of solidifying alloy by investment expansion. The metal ...

Under the present regime of globalization and liberalization, quality enhancement and cost reduction are two major steps to enhance productivity in major Industries. We focused on the very practical, safe, economical and rewarding strategies i.e. the application of LOW COST AUTOMATION. In Industry which uses of automation, a sequence is followed in the manufacturing of number of products of the...

Thermal expansion and hot deformation are two phenomena causing dimensional errors in investment casting. This error occurs in dimensions between the die and wax pattern. Therefore, the wax's thermo-physical and thermo-mechanical properties, the metal die features, and the process parameters affect the dimensions of the wax pattern. Some important effective process parameters are the injection ...

Purpose: The aim of the work is presents the influence of casting method and anodic treatment parameters on properties, thickness and structure of an anodic layer formed on aluminium casting alloys. Design/methodology/approach: Investigations were carried out on the laser profile measurement gauge MicroProf from company FRT, abrasive wear test was made with using ABR-8251 equipment delivered by...

This paper proposes data-analytics-based factory operation strategies for the quality enhancement of die casting. We first define four main problems casting that result in lower quality: [P1] gaps between input and output parameter values, [P2] occurrence preheat shots, [P3] lateness defect distinction, [P4] worker-experience-based tuning. To address these problems, we derived seven tasks shoul...

Al-Cu-Mn is one of typical heat-treatable cast alloys with high strength which has been widely used in aerospace and automobile industries. The complete manufacturing process for AlCu-Mn components includes low pressure die casting, T6 heat treatment and machining. It has been found that the property in former process has been transferred to the sequent step with considerable effect. In this pa...
