| Introduction |
|
Citimetal, in its search for providing our customer with five stars service, made the decision to execute all laboratory analysis and material tests inside of our facilities. Therefore, the most critical tests, such as chemical analysis for example, can be performed “on the spot”, reducing the test-result delivery time and thus increasing the speed of our production process.
Because of our orientation to international markets, we know that results vary from one laboratory to the other and that testing practices and methodologies change from one country to other, or even from one industry to the other. Given the diversity of markets and industries that Citimital caters to, the necessity to provide our customers and suppliers with an easy way to understand and evaluate our results was very clear. In line with the idea that clear reference points facilitate communication and minimize the occurrence of errors, we have worked towards the standardization of our laboratory, and now we are proudly the first precision investment casting foundry in Taiwan with an ISO/IEC170251 certified material testing laboratory.

| As part of our policy, all laboratory equipment must be handled only by properly trained personnel. In such way we assure the correctness of the results and assure that the equipments are kept in excellent operation conditions at all times. Therefore, each machine has an assigned operator, who is responsible for the maintenance, calibration and operation of the machine. |
| Our laboratory currently counts with the following equipment: |

High-temperature combustion is produced by high-voltage electrons and the atoms emit spectral lines uniqeue to the element. The elements and components contained in the sample can be measured by the wavelength and intensity of the spectral line. By gratings separate the spectral lines of different wavelengths from the incident light, and different elemental wavelengths will be detected at different positions in the optical chamber. |

1. Based on the mechanical test, it provide the data such as proportional elastic limit, elastic limit, elastic modulus, yield strength, tensile strength, bursting strength,elongation, contraction of area and so on. which are use as the standard reference of the mechinical propeties for research and development.
2. The engineering response can be obtained based on the displacement of the samples after the tensile test.
3. The tensile test is to test the resisting load when the sample is in a static state or subjected to a slowly increasing load.

Impact is applied to the notched impact test specimen. The magnitude of the energy received when the test specimen is broken is the toughness of the material.
1. The toughness can be used to judge whether the material will undergo brittle failure during use.
2. Investigate the impact value and the condition of the fracture surface.
3. Understand the relationship between the toughness of materials and temperature.
The impact test is the law of conservation of energy. The impact energy is measured according to how much the pendulum loses after impacting the specimen. The energy unit of impact work is Joules.

The image measuring instrument is used in the field where two-coordinate measurement is the target. The measuring image is transmitted to the computer data card through the data cable, which can be quickly measured and inspected on the monitor. |

Generally, the measuring instruments are for the X, Y, and Z axes, but as the Z axis is only for depth measurement, it is relatively simple, so mostly it is called by 2.5D, which is not really a 3D measurement.
【The main function】
1. Image measurement: quick image acquisition, range frame selection, automatic point finding, boundary detection tool, image overlay contrast.
2. Geometric measurement: basic measurement, combined measurement, shape and position error evaluation, coordinate positioning.

The space object is composed of the coordinate dimensions of the three-dimensional space, that is, three length dimensions: length, width, and height. Therefore, if there is a measuring instrument that can simultaneously measure the size of the three-dimensional space, that is, the space coordinate value, this measuring instrument is called a three-dimensional coordinate measuring instrument.
The three-dimensional measuring instrument can be defined as "a detector with three directions that can be driven manually or by a controller to control the motor. It can be moved on three mutually perpendicular guide rails. This detector is in contact or non-contact mode. Send signals, the three-axis displacement measurement system (such as optical ruler) calculates the coordinates (x, y, z) of each point of the workpiece and the instrument for measuring various functions through a data processor or computer.

Ferrite, also known as alpha iron (α-Fe), body-centered cubic structure, is a microstructure of steel, usually a solid solution of a small amount of carbon in α-Fe, generally Impurities such as other alloys and elements may be dissolved in the steel. Meanwhile, fertilized iron is also one of the constituent texture of boron iron and toughened iron. Fertilized iron is ferromagnetic, so it is also a source of magnetic properties for steel materials.
Features: non-destructive measurement of ferrite content in the field or in the laboratory is instantly operated.
Measuring range: 0.1-80% Fe or 0.1-110 FN.
The unit of measurement can be the percentage of ferrite "% Fe" or the number of ferrites "FN".
Measurement is according to ISO 17655 or "Bausel Standard".

The detection method is to detect defects on the surface of the material by penetration of liquid, which can cover and show the size of the discontinuity. The above discontinuity can be a flaw or crack, which is the basic principle of flaw detection. |

Due to the nature of our process, many of the studies require that the material is destructed in some way. Take as an example spectrographic analysis, in which the metal is vaporized to determine its chemical composition, or the impact test, in which a metal specimen is hit in order to determine its resistance to impact. However, such kind of analysis are not suitable for testing final goods, and thus we need to rely on Non Destructive Testing (NDT).
NDT refers to a set of material testing methodologies used to evaluate if the characteristics of a material complies with customer’s specifications without causing damage to the test subject. In order to assure the good quality of the final goods, a series of NDT can be performed in the finished products, according to customer’s requirements, such as:
