Mould wall friction effects on micro injection moulding based on simulation of MIS

IOP Conference Series: Materials Science and Engineering, 2010
Based on simulation Code MIS, this paper is mainly on the mould wall friction effects to understand more deeply about the flowing behaviour in micro injection moulding. In this study, how the mould wall friction affects the melt flow is demonstrated by comparing the simulation results, between the situation where mould wall friction is considered and ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

Advanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Micro-injection Moulding of Polymer Locking Ligation Systems

Procedia CIRP, 2016
AbstractIn recent years, there has been an increment on micro-components for medical purposes, diseases treatment and surgical equipment, requiring biocompatible materials such as some engineering polymers. Nonetheless, the micro size of these parts impose challenges for fabrication using high production processes, like polymer injection moulding ...

Innovative design and simulation study of a mould for rapid temperature control in micro-injection moulding [PDF]

AIP Conference Proceedings, 2019
Precise temperature control of the mould surface is a key factor for optimising product quality in micro-injection moulding. The ability to rapidly rise or decrease the temperature during the moulding cycle adds further processing benefits including increased productivity, increased freedom of design, and increased quality levels in the finished part ...
