Pune-based Maxtech, with a staff of 80, manufactures sintered
components for automotive engines and transmissions plus stainless steel components for exhaust applications.
Each laser sintered
spring showed off a nearly linear spring characteristic.
The powders were compacted and then sintered
in moulds (ISO-63 type graphite).
Metals specialises in powder metal parts for high stress applications such as gears and sprockets, and supplies the automotive, lawn and garden and office equipment markets.
Figure 2 depicts the effect of sintering temperature on density and relative density of sintered
The particles sintered
at 250AdegC after the preparation at pH 3 and pH 9 has elongated rod like and spherical shapes respectively.
The densities of the samples sintered
at different temperatures were evaluated based on the external dimensions and mass of the pellets.
A significant change between un-sintered and sintered
densities was observed with the addition of SiC particles and the trend continues with the increasing wt.% of SiC, it was attributed to shrinkage of pores during sintering .
The three different compacting methods used for preparing the sintered
ZnO ceramics are described as follows:
The pellets, also known as green ceramic pellets, must have at least 50% of relative apparent density in order to attain final densities in the sintered
ceramics that are high enough to be useful (usually higher than 90%).
The sintering temperature in this study is mainly determined by reference to the sintering temperature of the high-temperature sintered
clay ceramsite, and the sintering time ranges from 6 to 15 minutes .
