OUR QUALITY

“Quality of our products and processes will be the key focus of every element of the company. We will carry out any and all actions with Total Quality Concepts in mind. We commit to be quality sensitive, and we promise to be committed to our commitment.” - The Management

The above statement is the guiding principle to the people for the company. Quality to them does not limit to products, but goes beyond that. Quality starts with the smallest of designs and grows into every process and activity. Even the smallest accounting slip should be complete with all required data and information. The company believes in Total Quality Concepts. It largely Focuses on two aspects.

1. People: People of the company in all departments and at all levels are trained in their jobs as well as in attitude to do their duty with utmost care. Their activities will have predefined parameters of performance. However, they will think ahead of the same and always improve. The people will carry attitude of not just doing their own work effectively but help the other around them to improve their quality. From the top management to the smallest operative, each individual is responsible for quality. This is the culture set in the company.

2. Processes: Whenever a fault is identified with the product or any other issue where checking or back tracking is required, the people will trace the reason for that fault. The system and procedures will be improved to make sure such an error or fault never arises.

Consistently trace out such system deficiencies and improve procedures that lead to zero rejection. The idea is to develop self sustaining quality systems through better practices.

The company has fully functional laboratory with qualified manpower and modern testing equipment. It is used from the stage of Raw Material purchase through in process material to Finished Goods.

The company will soon be awarded by below mention certification for their efforts to maintain Total Quality Systems.

In House Facility

Quality / Material Handled

Committed to quality, we adopt rigorous quality checking systems to come up with the best products. Conforming to the international standards and parameters, our products are high on all the three aspects that are: performance, durability and utility.

Chemical Testing

Chemical testing using Spectrometer Spectromax-X (made in Germany), which is well calibrated using setting up samples and certified reference materials.

We have ability to check seventeen elements in our spectrometer, like as C, Si, S, P, Mn, Ni, Cr, Mo, Cu, V, Ti, W, Co, Nb, N, Al and Fe.

Tensile Testing

Tensile testing with 0.2% and 1 % Proof Stress by using Computerised Universal Testing Machine with Extensometer by 20 ton capacity of MAKE “TESTWEL” and Calibrated by NABL Approved lab.

Tensile Test

A tensile test, also known as tension test, is probably the most fundamental type of mechanical test, we perform on material.

If we continue to pull on the material until it breaks, we will obtain a good, complete tensile profile. A curve will result showing how it reacted to the forces being applied. The point of failure is of much interest and is typically called its "Ultimate Strength" or “S” on the chart.

Proof Stress

Offset Method:

For metals the departure from the linear elastic region cannot be easily identified. Therefore, an offset method to determine the yield strength of the material tested is allowed. These methods are discussed in ASTM E8 (metals). An offset is specified as a % of strain (for metals, usually 0.2% from E8). The Proof stress that is determined from the intersection point, when the line of the linear elastic region (with slope equal to Modulus of Elasticity) is drawn from the offset becomes the Yield Strength by the offset method.

Impact Testing (Charpy Test)

Impact testing Facility is available at Room Temp. -46 Degree Centigrade and also at -196 Degree Centigrade, which is well calibrated by NABL approved Agency. And also complies with requirements of ASTM E23. Impect Value is measured in Joule.

Impact testing is testing an object's ability to resist high-rate loading. An impact test is a test for determining the energy absorbed in fracturing a test piece at high velocity.

OUT SOURCE PROCESS

Design & Simulation

“Design to make right the first time with collaborative engineering.”

MTPL with help of customers in premature designing stages for building their product-design in the concept of “Design for Manufacturing” to make it “Right the first time”.

MTPL offer in-house facility for 3D modeling and 2D CAD drawings using latest CAD software. We can also work from customer supplied 3D models in various forms like Parasolid, IGES, STEP, UG Files.

Micro-Structure Analysis

Micro structure and other related testing is done as per Customer requirement.

NDT Testing:
We can carry in house various Non Destructive Testing Like as Radiography Testing, Liquid Penetration Test, Magnetic Particle Inspection.

Also serve additional Testing Facility like as Pressure testing, IGC Testing like as A,B,C.

Brinell Hardness Test

The oldest of the hardness test methods in common use today, the Brinell test is frequently used to determine the hardness of forgings and castings that have a grain structure too course for Rockwell or Vickers testing. Therefore, Brinell tests are frequently done on large parts. By varying the test force and ball size, nearly all metals can be tested using a Brinell test.

Brinell testing is typically done on iron and steel castings using a 3000Kg test force and a 10mm diameter carbide ball. Therefore the typical range of Brinell testing is 500 to 3000Kg with 5 or 10mm carbide balls.

Brinell Test methods are defined in the following standards:

•   ASTM E10
•   ISO 6506

Rockwell Hardness Test

Rockwell test method is simple sequence of test force application proved to be a major advance in the world of hardness testing. It enabled the user to perform an accurate hardness test on a variety of sized parts in just a few seconds.

Rockwell test methods are defined in the following standards:

•   ASTM E18 METALS
•   ASTM 6508 METALS
