R&D Center

1-Purpose

Organize the company's technical work to ensure the normal operation of the company's quality system.

The research and development of new products, new technologies and new equipment improve the core competitiveness of enterprises.


2-GRAIN SIZE EXAMINATION

In an "as-received grain size examination”, we prepare metallographic specimens from the sample without any additional treatment. For example, an as-received grain size examination can be performed for Aluminium alloy that haven't been quenched.

3-MICROHARDNESS TESTING

Specific fields of application of microhardness testing include:
Small Samples unable to be tested by conventional methods.
Foil and thin wire.
Carburizing or nitriding operations to measure cross sections.
Micro constituents of assemblies.
Measuring hardness close to the edges of work pieces for anomalies.
Measuring the hardness of surface layers such as plating or bonded layers.


4-Organizational Structure

R & D engineer-participate in the demonstration of the R & D project, design the part of the process route, experimental plan and other work. Participate in the design, development and improvement of new processes.


These processes of recovery annealing and recrystallisation annealing are accompanied by a modification in the texture and size of the agrainso in the metal. During recrystallisation therefore, reorganisation takes place according to a new grain structure.


There are a number of requirements for obtaining an annealed metal with a fine grain:

The metal must have received a sufficient rate of working, corresponding to a relative reduction in section of at least 15%. If this requirement is not met, then the metal must undergo recovery annealing only (i.e. recrystallisation annealing must be avoided).

The rate of temperature rise must be rapid, from 20 to 60!C per hour, Excessive temperatures, above 350 to 400!C, and excessive temperature holding times, i.e. not more than 2 hours, must be avoided.
