During the design of a two-cavity injection mould for router covers, two plans, single-gate plan and dual-gates plan, were setup based on the results of best gate location analysis combined with other aspects. Then fill analysis for the two plans were carried out. The dual-gates plan was selected as an optimal choice for its smaller clamping force, wall shear stress and injection pressure in co...

Power box is a component which is used in earth movers. It controls the power circuit. It has top cover, front cover, back cover and side panel. The aim of the paper is to create the L&T power box side panel by using parametric pro/E wild fire 5.0. The part modeling, Core-cavity design, CNC manufacturing programming and Mould flow analysis i.e simulation to avoid potential mould-filling problem...

This paper is concerned with the injection moulding process, in which hot molten plastic is injected under high pressure into a thin cold mould. Assuming that the velocity and temperature profiles across the mould maintain their shape, a simple steady state model to describe the behaviour of a Newtonian fluid during the rilling stage is developed. Various phenomena of the process are examined, ...

Abstract The design process of the injection mould for Lithium battery heat dissipation device connector bottom cover is described in detail. In process, UG software used to establish three-dimensional model plastic part, and flow analysis carried out with help moldflow determine optimal gate position part. By determining parameters material, cavity layout part completed, basic size structure b...

This paper presents an automated vision based defect inspection and sorting system for a plastic injection mould component called a Retractor Retaining Bush, which is an automotive safety critical component. The system identifies defects which usually occur in a plastic injection mould component. Various types of sensors and actuators were interfaced with the vision hardware and the part handli...

A variety of parts in microsystems technology are manufactured by injection moulding of polymeric materials. In Particular the high cooling velocity affects negatively the process and the resulting part properties. The scope of this paper is to investigate the influence on the reachable flow length in injection moulding of different polymeric materials. The results indicate that the mould tempe...
