Nowadays, the globalization of the manufacturing enterprises requires collaboration across frontiers. In order to attain effective collaboration, the information about the product life cycle must be captured and administrated in a way that supports the decision taken during the product development. In this context, the manufacturing process information needs to be shared between manufacturers. ...

Introduction Computational fluid dynamics (CFD) has been used to simulate the flow during vacuum infusion [12], sheet moulding compound (SMC) [3-4], the auto-clave process [5] and twin-screw extrusion. Three-dimensional geometries were studied and porous media and multiphase flows were treated with a homogenous approach. The advantages and drawbacks of such a methodology are here discussed base...

Design methodology and criteria to configure sprue bush for enhancing functionality is systematically compiled from plastic injection moulding machine perspective. Sprue conduit’s sensitivity to moulding objectives are quantitatively ghettoised as expansion ratio on the basis of ubiquitous empirical relationships. This generic, simple, inexpensive preventive criterion enables sprue bush conduit...

An original approach to compute the longitudinal tensile break stress of multiphase composite materials with short fibers reinforcement is presented. The most obvious mechanical model which reflects a multiphase composite material is a pre-impregnated material, known as prepreg. We may include in this class of prepregs, Sheet-and Bulk Moulding Compounds. The model is seen as consisting of three...

We present a simple cell docking method induced by receding meniscus to capture non-adherent yeast cells onto microwells inside a microfluidic channel. Microwells were fabricated either by capillary moulding of UV curable polyurethane acrylate (PUA) onto glass substrate or direct replica moulding of poly(dimethyl siloxane) (PDMS). A cell suspension of the budding yeast, Saccharomyces cerevisiae...

Cleft lip and palate (CLP) is the most common congenital deformity of the oral cavity. Recently, nasoalveolar moulding (NAM) has evolved as a presurgical technique which reduces the severity of the oronasal defect. NAM improves the facial appearance and function by moulding the nasal cartilages, premaxilla, and the alveolar ridges before the corrective surgical procedures. Utilization of the NA...

In this study, compressive strength and contraction of Polymer Composite Laminates made of E-Glass / Carbon bi-woven fabric reinforced in Epoxy resin matrix has been evaluated experimentally. Composite laminates were fabricated using hand lay-up technique for different ply orientations of 0,30,45,60 and stacking sequence of (00/300/450/600)2S for 2 and 3 mm laminate thickness. The laminates wer...

This paper presents a software tool for automating the design of cooling systems for injection moulding and a validation of its performance. Cooling system designs were automatically generated by the proposed software tool and by applying a best practice tool engineering design approach. The two different design methods (i.e. automatic and manual) were applied to the mould design of two thin-wa...

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...
