Microsystem technologies are believed to be an important part of the technological foundation upon which the world can continue to improve the standard of living in the twenty-first century. Microelectromechanical systems (MEMS) have been studied intensely for over two decades. Si-based MEMS, fabricated by surface and bulk micromachining techniques derived from IC processing technology, dominat...

nasoalveolar molding represents a paradigm shift from traditional presurgical orthopedics in the care of cleft lip and palate patients which has been applied increasingly in the past two decades. this article is a review of recent literature apropos of objectives, appliances, complications and short and long term effects of this technique.

This paper focuses on an integrated optimization problem that involves multiple qualitative and quantitative responses in the thin quad flat pack (TQFP) molding process. A fuzzy quality loss function (FQLF) is first applied to the qualitative responses, since the molding defects cannot be simply represented by the relationship between molding conditions and mathematical models. Neural network i...

The incidence of auricular deformities is believed to be ∼11.5 per 10,000 births, excluding children with microtia. Although not life-threatening, auricular deformities can cause undue distress for patients and their families. Although surgical procedures have traditionally been used to reconstruct congenital auricular deformities, ear molding has been gaining acceptance as an efficacious, noni...

Taking the special-shaped plastic part as the research object, numeric simulation and experimental study of the injection molding process are completed based on the synthetical application of numeric simulation technology, orthogonal experiment method, Moldflow, injection machine and CMM. Optimal feeding system and molding process parameters are obtained and qualified products are produced. The...

This article describes the use of a newly invented compound stick gun to take impressions for complete denture. The border molding process involves loading the modeling compound in an electric heating device and applying an even thickness of compound on the flange of a custom tray at a proper temperature without hot water tempering. This method provides a quicker and easier border molding proce...
