Micro Injection Moulding of Polymeric Components

AIP Conference Proceedings, 2011
Micro components and micro devices are strongly used in several fields: IT components, biomedical and medical products, automotive industry, telecommunication area and aerospace. A micro component is characterized by small dimensions of the product itself or small dimensions of the functional features.

Micro-injection Moulding

2017
The micro-injection of plastics is currently the technology with the greatest future potential development for the manufacture of plastics components weighing less than 1 g and with tolerances in the range of 10–100 microns, thus allowing complicated geometries and high surface quality.

Micro powder injection moulding

Microelectronic Engineering, 2006
Powder injection molding (PIM) has emerged as a viable method for producing complex shaped parts at a competitive cost. The PIM process, which consists of feedstock preparation, injection molding, debinding and sintering, uses a combination of powder metallurgy and plastic injection molding technologies to produce net-shape metal, ceramic or hard ...

Polymeric Micro-Filter Fabrication Using a Micro Injection Moulding Process

Volume 4: 20th Design for Manufacturing and the Life Cycle Conference; 9th International Conference on Micro- and Nanosystems, 2015
This paper reports on fabrication and characterization of a micro-filter for hearing aid, dialysis media and inhaler. The micro-feature specifications consist in a diameter of 2.3 mm, a thickness of 0.2 mm and it is composed by a mesh with grid of 80 μm and ribs with width of 70 μm.

Thermal Contact Behaviour in Micro-Injection Moulding

ASME 2008 6th International Conference on Nanochannels, Microchannels, and Minichannels, 2008
Micro-injection moulding is one of the most efficient technologies for large-scale manufacturing of thermoplastic polymer micro parts. Growing demands for high precision require new concepts for moulding machines and micro moulds on the one hand and a better understanding of the process characteristics on the other hand.

Cavity Pressure Behaviour in Micro Injection Moulding

Proceedings of the 7th International Conference on Multi-Material Micro Manufacture, 2010
Process monitoring of micro injection moulding (µIM) is of crucial importance to analyse the effect of different parameter settings on the process and to assess its quality. Quality factors related to cavity pressure can provide useful information directly connected with the dynamics of the process as well as with the filling of the cavity by the ...

Micro powder-injection moulding of metals and ceramics

Sadhana, 2003
Development of micro-MIM/-CIM was started at Forschungszentram Karlsrahe with the aim of creating a process suitable for a wide range of materials as well as for medium-scale and large-scale production of micro components. Using enhanced machine technology and special tempering procedures, this process enables the manufacturing of metal and ceramic ...

Mechanical properties of micro-injection moulded components

Macromolecular Symposia, 2002
Micro-injection moulded specimens and components were investigated using instrumented indentation testing and tensile testing. Conventional nano indentation testing, from which hardness and modulus can be obtained, is useful for the characterization of thermoplastics and filled thermoplastics. The difficulties of indentation measurements on LCPs can be

A New Approach For The Validation Of Filling Simulations In Micro Injection Moulding

AIP Conference Proceedings, 2007
In manufacturing polymer micro products, numerical simulations are used with the same purposes as in conventional injection moulding, mainly the optimization of micro components design, the optimization of process parameters and the decrease of production costs. Dedicated simulations softwares fail to correctly describe the melt flow in microstructures,

Influence of Injection and Cavity Pressure on the Demoulding Force in Micro-Injection Moulding

Journal of Manufacturing Science and Engineering, 2014
The paper reports an experimental study that investigates part demoulding behavior in micro-injection moulding with a focus on the effects of pressure and temperature on the demoulding forces. In particular, the demoulding performance of a representative microfluidics part was studied as a function of four process parameters, melt temperature, mould ...
