Measuring the physical properties of parts and raw materials can help you determine their durability and give you an insight of how they will perform under application. Improper machining, wrong material selection and exposure can all affect your materials and potentially cause costly failures and recalls.
DMSPL mechanical testing division offers a wide range of testing to evaluate metals, composites and finished products. From routine tensile testing to Failure Analysis. We are equipped to provide all the answers you need. Most testing is completed within the same day, for tensile, hardness and Charpy/Izod impact testing. Testing is always carried out in complies with IS, ASTM, ASME, DIN, API, JIS standard Testing can also be done in various condition as per the customer specifications, such as temperature, tension, compression, impact and load to determine the material specification and material property of application environment.
Tensile testing, also known as pull testing, is a standard test method where a sample is placed in grips and subjected to controlled tension until it fails. This provides valuable information about materials including ultimate tensile strength, yield strength, elongation and reduction in area. This information allows us to determine Young's modulus and Poisson's ratio.
DMSPL offers tensile testing for metals, weld specimens, coatings, powdered metals, tubes, pipes, wire and fiber-reinforced composites.
Load testing is the process of applying controlled amount of load on a given test specimen and measuring its response. Load testing is performed to determine a system's behaviour under both normal and anticipated peak load conditions.
In materials science, fracture toughness is a property which describes the ability of a material containing a crack to resist fracture, and is one of the most important properties of any material for many design applications.
Bend test deform the test material at the midpoint causing a concave surface or a bend to form without the occurrence of fracture and it measures the ductility of materials. Terms associated with bend testing apply to specific forms or types of materials. For example, materials specifications sometimes require that a specimen be bent to a specified inside diameter (ASTM A-360, steel products).
specifications use a single lap joint (lap shear) specimen to determine the shear strength of adhesives. Shear joints impose uniform stresses across the bond area which results in the highest possible joint strength. ASTM D1002 is commonly performed to measure the shear strength of adhesives that are used to bond metals
A compression test determines behaviour of materials under crushing loads. The specimen is compressed and deformation at various loads is recorded. Compressive stress and strain are calculated and plotted as a stress-strain diagram which is used to determine elastic limit, proportional limit, yield point, yield strength and, for some materials, compressive strength.
The flatting test involves multistage flatting of a tube section, for check the plastic deformation capacity of the tube sample. DMSPL performing this test in accordance with common standards (i.e IS, ASTM, EN).
The sample is expanded by 60˚ tapered mandrel until the percentage of flaring of outside diameter obtains valves stated under standard. Sample preparation should be as 150mm diameter and 10mm length. DMSPLconducts flaring test in accordance with IS, ASTM and EN standard.
Flange the end of the tube symmetrically by means of a hardened conical steel mandrel having an included angle of approximately 90˚. The mandrel is to be forced into the test specimen until the drifted portion has formed a flange perpendicular to the axis of the test specimen.The percentage increase in the outside diameter of the end of the test specimen is not less than the value given in the specification requirements.DMSPLconducts flaring test in accordance with IS, ASTM and EN standard.
Cupping test are employed in the testing of the elongation and deformability of lacquers and protective applied to metal substrate. This sort of test is because it allows one to test the durability of a lacquers and protective coating before the coating is applied to a product.
Welder & Procedure Qualification (as per MIL & API specification, ASME & AWS codes, ASTM, EN standards and the Pressure Equipment Directive
A V-notch impact test is a dynamic test in which a notched specimen is struck and broken by a single blow in a specially designed testing machine. The measured test value is the energy absorbed, the percentage shear fracture, the lateral expansion opposite the notch, or a combination thereof
Hardness testing is a basic test used to verify raw materials or as a quick check for materials that fail or aren't performing as expected. Hardness tests quantify the resistance of a material to plastic deformation and is available as micro-indentation or macro-indentation. DMSPL offers a range of hardness and micro-hardness testing to meet your needs. We offer hardness testing on metals (Rockwell, Brinell) and micro-hardness testing (Macro Vickers, Vickers, Knoop).
This test to determine adhesiveness of materials with each other by applying tensile force on sample. it is applicable on two materials, coating resin, coatings etc.
Using surface contact probing technique, a surface roughness evaluation is performed. It is a very standard practice used to show the unevenness of the surface at the microscopic level.
