Warpage analyses on thin plate in three-plate mold by Taguchi method and analysis of variance (ANOVA) for PC, ABS and PC/ABS
(Praise Worthy Prize S.r.l., 2012)
Warpage is a common issue in plastic injection molding process. It can get worse for thin parts and therefore it is more challenging for product design engineers, mold designers and manufacturing engineer to cope with ...
The influence of different mold temperature on warpage in a thin shallow injection molding process
(Praise Worthy Prize S.r.l., 2012)
Every injection molding parameter have its own influence towards the quality of an injection-molded part. Temperature, pressure and time are main parameters that typically highlighted in controlling the warpage defect of ...
Optimization on parameter settings in determining warpage factors of a side-gated thin shallow part injection molding for PP, ABS & PC+ABS materials
(Praise Worthy Prize S.r.l., 2012-05)
The injection molding process of thin shallow part requires several concerns in order to produce a quality output. In part of determining the best parameter settings, among other considerations that need to be taken are ...
Optimal process conditions of warpage with thin-shallow features molded with pin-point gating system
(Praise Worthy Prize, 2011-11)
Thin shallow plastic parts are widely produced using injection molding processes in producing varieties of components and applications. Warpage issue always happens in manufacturing thin shallow parts due to its uneven ...
Investigation on Nylon PA66 side arms using Taguchi and ANOVA analysis in reducing cost of producing urinary catheters
(Praise Worthy Prize, 2011-11)
This article discusses on a research experience and finding based on a collaboration with a medical equipment manufacturer in producing urinary catheters. The manufacturer had been spending high cost yearly to replace more ...
An approach to mechanization and automation of manual construction activity
(Praise Worthy Prize S.r.l., 2011-11)
Construction industry is very important to the developing country like Malaysia. Many challenges and difficulties must be faced by the developers of this particular field. Warszawski et. al [1] has reported that there are ...
Potential of conformal cooling channels in rapid heat cycle molding: a review
(Wiley Periodicals, Inc., 2014)
Rapid heat cycle molding (RHCM) can eliminate the weld line, increase flow length, and improve surface quality of the molded parts. However, the cycle time is much longer as compared to the conventional injection-molding ...
Parameter estimation of damped compound Pendulum using Bat Algorithm
(EDP Sciences, 2016)
In this study, the parameter identification of the damped compound pendulum system is proposed using one of the most promising nature inspired algorithms which is Bat Algorithm (BA). The procedure used to achieve the ...
Optimisation of Shrinkage and Strength on Thick Plate Part Using Recycled LDPE Materials
(MDPI AG, 2021-04-05)
Achieving good quality of products from plastic injection moulding processes is very challenging, since the process comprises many affecting parameters. Common defects such as warpage are hard to avoid, and the defective ...
Tool wear and surface evaluation in drilling fly ash geopolymer using HSS, HSS-Co, and HSS-TiN cutting tools
(MDPI AG, 2021-03-26)
This paper reports on the potential use of geopolymer in the drilling process, with respect to tool wear and surface roughness. The objectives of this research are to analyze the tool life of three different economy-grade ...
