Moreover In 2016, Panaplus Group has made a substantial invesment in building a brand new testing laboratory in order to enhance our casting quality further and to minimise any unexpected manafacturing errors. We believe this investment will also expand our capabilities by experimenting with potential casting products for future scenarios.
1) Spectroscopy Analysis
Spectroscopy is the analytical technique used to determine the element composition of a cast iron. At PANA-TAGUCHI we use this equipment to ensure that every cast iron we produce meet the specification and customer's requirement.
2) Microstructure Analysis - At PANA-TAGUCHI we use Metallurgy Microscropes to identify the characteristics of the cast iron including
Graphite Type (Form) • Graphite Distribution • Graphite Size • Graphite Nodularity • Percent Graphite • Percent Ferrite-to-Pearlite
Classification according to Form of Graphite gave origin to a term called "Nodularity", which indicates the percentage of Graphite in nodular form. For example, Cast Iron rated at 100% Nodularity contains all of its graphite in the Form of nodules (Form I Graphite), whereas 80% Nodularity means that the Cast Iron contains 80% of nodules and 20% of other form(s) of graphite. Summary Unlike former techniques where operators performed a visual estimation of the Graphite size, nodularity, form or distribution manually by eye, modern material-science microscope specific image-analysis software allows the Graphite parameters to be calculated accurately and repeatedly, as human intervention is minimized. Many software packages are designed to comply with ASTM A247 and a wide-range of international standards, and can be implemented with minimal efforts. Going beyond the scope of the analysis, many software packages additionally offer the ability to automatically generate reports based on the analysis data, and even go so far as providing an integrated database solution for archiving and quick-and-easy searching of images and related data. When considering a turn-key solution for automatic Cast Iron analysis, working directly with an experienced material-science specific microscope manufacturer is of utmost importance, as they can assist you in every step of this process, from equipment selection to full deployment.
3) Mechanical Test - Elongation - Tensile stregth
- Mechanical testing measures the tensile strength, yield strength and elongation for iron casted products. At Pana-Taguchi, our castings go through a complex process to ensure customer satisfaction, where we use a computer lathe, or CNC, to shape tensile bars to a high degree of accuracy so the sample is perfectly representative of how the end product will turn out and meet the needs of our customers. Tensile testing, is also known as tension testing, is a fundamental materials science test in which a sample is subjected to a controlled tension until failure. The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. The material will be tested by the machine called "Universal Testing Machine"
4) Hardness Test
There are three main types of hardness measurements: scratch, indentation, and rebound. At PANA-TAGUCHI we use Rockwell hardness testing which is a general method for measuring the bulk hardness of metallic. The Rockwell test is generally easier to perform, and more accurate than other types of hardness testing methods. The Rockwell method measures the permanent depth of indentation produced by a force/load on an indenter which it correlates directly with its strength, wear resistance, and other properties. However, the equipement must be calibrated frequently to make sure that the results are accurates and meet the customer's specification
5) Ultrasonic Test
This method is used to determine the nodularity of a cast iron by longitudinal ultrasonic velocity. As the % nodularity increases, the ultrasonic velocity also increases. At PANA-TAGUCHI we use this technique as one of our quality check process to get a rough idea for nodularity percentage of each casting product.
6) Sand Quality Check
This method is used to monitor the moisture of sand use in the moulding line. At PANA-TAGUCHI we use this method to ensure that the moisture level of sand is kept at a standard level for avoiding gas porosity issue inside the casting products.
