We propose a combinatorial approach to plan noncolliding motions for a polygonal bar-and-
joint framework. Our approach yields very efficient deterministic algorithms for a category of …

Weldlines are one of the major defects in plastic injection molding (PIM). Since the weldlines
have an influence on not only the appearance of product but also the strength, it is important …

Injection molding process parameters such as injection temperature, mold temperature, and
injection time have direct influence on the quality and cost of products. However, the …

In this study, a multi-objective design optimization method based on a radial basis function
(RBF) model was applied to minimize the volumetric shrinkage and warpage of hip liners as …

Weldlines are one of the major defects in plastic injection molding (PIM). The weldlines have
an influence on not only the appearance of product but also the strength, so it is important to …

The paper presents a new procedure for the automated calculation of cycle time in the
injection molding process based on the recognition of the geometry of the plastic part to be …

For most strip-like plastic injection molded parts, whose cross section size is much smaller
than their length, the traditional Hele-Shaw model and three-dimensional model do not work …

This goal of this paper is an optimization approach to generate suitable process setting of
multi responses of the minimization of warpage and volume shrinkage in the plastic injection …

Design of gate location is among the most critical factors in achieving dimensionally
accurate parts. To optimize the gate locations, it is proposed that the injection pressure at …

In the current mould-making industries, the challenge is to shorten the mould lead-time while
maintaining the desired quality. This is one of the main demands from customers so as to …
