The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...

Mechanical properties response of extruded 6063 aluminum alloy at varied die entry angle has been investigated. Plain carbon and tool steel dies with entry angles of 15, 30, 45, 60, 75 and 90 were simulated. Extrusion on the alloy was done at ambient temperature (37C) and the extruded samples from the various angles were subjected to selected service related mechanical tests and microstructural...

BACKGROUND Injection molding is an important manufacturing process for optical and mechanical components. The hard steel dies used in injection molding play a direct role in the quality of molded parts. Traditionally, fabricating the dies involved rough milling followed by heat treatment, grinding and polishing. Recently, high-speed machining of heattreated steel (hardness > 55 Rc) has become a...

Injection molding is an important manufacturing process for optical and mechanical components. The hard steel dies used in this process play a direct role in the quality of molded parts. Traditionally, fabricating these dies involved rough milling followed by heat treatment, grinding, and polishing to the desired shape.

In the moulds and dies manufacturing it is important to reduce the manual polishing time after end milling processes. The polishing difficulty is related to surface topography shape and roughness values obtained in the previous end milling processes. It is interesting to develop a methodology and a test to evaluate the polishing difficulty. The aim of the present work is to establish a methodol...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...
