Injection moulding simulation results as an input to the injection moulding process
Journal of Materials Processing Technology, 2002Abstract In the presented research work the authors tried to develop the software which will suit all the needs of the injection moulding when optimising the part-mould-technology system. The simulation results consist of geometrical and technological data.

Injection moulded hydroxyapatite ceramics
Biomaterials, 1996The injection moulding of hydroxyapatite (HA) and properties (relative density, shrinkage, microstructure, thermal strength and phase composition) of HA ceramics sintered at temperatures of 1373-1773 K were studied. Particles of oval shape and size of 0.5 microns were most suitable for injection moulding.

Injection moulding of biodegradable implants
Clinical Materials, 1992In medical engineering, degradable polymers represent an attractive alternative for conventional materials to be used as implants in the body. They are used as drug deliveries or as plates and screws to fix broken bones. Since they are completely broken down by the human body, the second operation, which is generally required, can be avoided.

A Comparison of Sandwich Injection Moulding and Sandwich Injection-Compression Moulding
Journal of Polymer Engineering, 2006Multi-component injection moulding has gained enormous importance over the last fifteen years. This is due to development of more sophisticated products and to the constant endeavours to cut costs. One new trend - the combination and integration of well-known processes to a new process - has become more and more important for some years and it still ...

Reaction Injection Moulding (Liquid Injection Moulding)
1992Reaction injection moulding (RIM), alternatively and probably more realistically called liquid injection moulding (LIM), or sometimes high-pressure impingement mixing (HPIM), is essentially a ‘one-shot’ process for moulding polyurethane elastomers by carrying out the reaction and moulding process through the sequence of steps shown in Fig.

Drug Development and Industrial Pharmacy, 1986
The paper describes the development of the first injection-moulded pharmaceutical capsules. Starch and gelatin capsules have been prepared and the processing conditions and properties of the resulting starch capsules are considered in detail. Comparisons are made between the processing of thermoplastics arid starch and gelatin and the starch capsule is

Statistical Monitoring of Injection Moulds
2008In this paper a statistical based methodology to work over the principal component space on injection moulds is presented. The Multiway Principal Component Analysis is applied as a dimensionality reduction step, and fault detection assessment. This methodology allowed to analyse the behaviour of injections with the information directly received from ...

In all but the simplest injection moulding configurations, there will occur in the mould filling process a situation in which two, or more, distinct melt streams will interact with each other. This may occur because of flow splitting by an insert within the mould and the subsequent recombination of the separated flows, or because of the collision of ...

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.

Powder Metallurgy and Metal Ceramics, 2004
Powder injection moulding, a relatively new technique for manufacturing articles of complex shape from metal or ceramic powders, is considered. Production operations are described in detail: powder mixing with a binder to form a slip, injection of the slip into a mold, binder removal, sintering of the billets obtained.
