A mold strength tester can be used in much the same manner as a hardness tester
, but it can be more definitive on harder molds (more than 92 mold hardness) than the C hardness tester
Operation with hardness tester
is as follows: at portable mode probe is pressed manually through mounting base 7 on tested material 4, at laboratory working mode, tested material 4 is pressed onto the base 7 until there is a pronounced strength.
Another principle for portable hardness testers
is the rebound method.
The hardness tester
is meant to determine all types of static stress hardness tests as well as of impact ones wherein impact hardness IH is expressed by the ratio between recoil kinetic energy [E.
The firmware of the hardness tester
was then redesigned to automatically carry out both user defined and ISO 642, ASTM A255 Jominy standard test cycles.
The DigiTest II automatic motorized hardness testing system is said to be one of the most impressive durometer/IRHD hardness testers
on the market, and its modular design makes it suitable to virtually every durometer/IRHD measurement scale for testing various polymers.
Krautkramer's new "DynaPocket" is a small, compact rebound hardness tester
conforming to ASTM Standard A956-00.
Instron introduced several new Wilson hardness testers
: the Tukon 2100 Microhardness Tester and Wilson Series 2000 Rockwell Hardness Tester
with closed-loop, load control designs; the Wilson MicroRockwell Hardness Tester
designed for high speed production testing of small or thin components; and the M-200A and M-250A, compact, light weight testers.
Also, Barber-Colman now offers individually certified test disks for its Impressor hand-held hardness tester
, allowing users to keep these testers calibrated in-house.
This DigiChamber consists of a hardness tester
and a temperature chamber that can carry out tests on a sample or by analyzing three different positions simultaneously, allowing companies to conduct more rigorous tests and ensure greater consistency across products.
The solution is to take the hardness tester
to the forging rather than the other way around," says Ed Nisbett, an independent consultant who is chairman of Subcommittee A01.
The laboratory will include an electronic universal sand strength machine, a digital absolute permmeter, a rapid sand washer, a digital ultrasonic cleaner, a sand rammer, a methylene blue clay tester, an electronic mold hardness tester
, a laboratory sifter and a drying oven.
