Research on Matrix Hardness of Coated Mould and its Performance Effect

Applied Mechanics and Materials, 2011
After researching the mould coating and the effect of different matrix hardness on the service life, it can be concluded that under the condition, the matrix materials match with its obdurability well, the higher the matrix hardness, the longer the service life after the mould’s being coated.

Tempering Process to Improve Hardness Uniformity of Plastic Mould Steel

Journal of Iron and Steel Research International, 2012
A new design of copper-bearing non-quenched plastic mold steel is presented and explained. Two kinds of microstructure can be obtained from this new type copper-bearing steel via cooling with different cooling rates, bainite and a mixed microstructure consisting of ferrite and bainite. It is found that, after proper tempering process, the hardness will

GA-fuzzy based estimation of equivalent hardness of particle reinforced flexible mould material composites

Journal of Intelligent and Fuzzy Systems, 2014
In the present work, an extensive experimental study on the equivalent hardness of various particle reinforced flexible mould materials is carried out. From the experimental study, it has been observed that the equivalent hardness of a composite mould material depend on many factors, such as filler content, morphology and type of filler particles, etc.

Study on microstructure and hardness uniformity of non-quenched prehardened steel for large section plastic mould

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2008
Abstract Microstructures throughout a 460 mm × 800 mm cross-section of non-quenched prehardened (NQP) steel for plastic mould were characterized by optical microscopy, scanning electronic microscopy and transmission electronic microscopy. Strength and hardness of the NQP steel block was also tested.

Mould contamination in production of semi-hard cheese

International Journal of Food Microbiology, 2004
Air, equipment, plastic film, brine and milk were sampled from four cheese factories in Norway during the period September 1997 to May 1999 in order to identify the critical points for mould contamination in the production process. Altogether, 672 samples were collected.

Mould growth on the Norwegian semi-hard cheeses Norvegia and Jarlsberg

International Journal of Food Microbiology, 2000
Visible moulds were isolated and identified from 102 samples of each of the Norwegian types of semi-hard cheeses called Norvegia and Jarlsberg. Penicillium species made up 98.1 and 89.2% of the isolates from the Jarlsberg and Norvegia cheeses, respectively. The most frequently occurring species on both was P. roqueforti subspecies roqueforti.

M303 HIGH HARD – a Corrosion Resistant Plastic Mould Steel with Higher Hardness

BHM Berg- und Hüttenmännische Monatshefte, 2010
Corrosion resistant prehardened DIN 1.2316-type tool steels (X36CrMo17) are generally used for plastic moulds or mould inserts in the plastics processing industry. The most important properties for these applications are corrosion resistance, polishability and good machinability at appropriate mechanical properties and a hardness of about 300 HB.
