A Wealth of Expertise

At KMP Brand, our Quality Department boasts an extensive repository of meticulously developed and rigorously approved drawings and samples. This invaluable resource forms the cornerstone of our commitment to precision. We frequently consult this repository alongside our expansive OEM Store, guaranteeing that every KMP Brand component adheres flawlessly to specified standards.

Elevating Standards: A Focus on Precision and Reliability

Our exacting quality control procedures stand as a testament to our dedication to excellence. Every single component undergoes rigorous scrutiny to ensure it meets our stringent specifications for reliability. We take immense pride in our ISO certification, a testament to our unwavering commitment to maintaining the highest industry standards.

CO-ORDINATE MEASURING MACHINE (CMM)

The CMM is used to measure the geometry of our parts using various probes. This machine can measure down to a resolution of 1 micron and is used to measure many parts including pistons, ring gears, crankshafts, camshafts and rollers.

DIGITAL MICROSCOPE ​​

The digital microscope can zoom up to 160x and is invaluable in the measurement of bearing material thickness, coating analysis (piston rings) and failure/crack analysis.

SHADOWGRAPH

Our Metrology team uses the Shadowgraph to perform dimensional inspections of critical components, such us valve angles and piston ring profiles, ensuring they meet exact engineering specifications to OEM standard. Whether it’s checking part profiles, verifying tolerances, or conducting comparative analysis, the Shadowgraph plays a crucial role in our commitment to quality assurance.

XRF Analyser

  • The latest addition to the KMP Quality Department is our new XRF Analyser, which determines the elemental composition of the material of a part through non-destructive spectroscopy.
  • All OEM parts can be tested using the XRF Analyser in order to the material specification to be identified. This information can be used in development to ensure that our parts will perform to the same standard as the OEM material.
  • Any KMP part failures can be fully analysed using the XRF Analyser to ensure that we maintain our high standards throughout our parts.

Tangential Tension Tester: Piston rings

The Tangential Tension Tester is used to measure the tension force of piston rings, a critical step in our quality control process. Accurate tension ensures the ring will maintain proper contact with the cylinder wall, directly affecting engine performance and reliability. Ensuring the tension is correct when developing a piston ring is essential within the drawing approval procedure and helps confirm that each piston ring meets the required specifications and will perform consistently with OEM standards. By verifying tension at this stage, we reduce the risk of failure and ensure that every ring we supply delivers the fit, seal, and function our customers expect.

ROCKWELL HARDNESS TESTER ​​

All hardened components are tested using either a Leeb Hardness Tester or the Rockwell Hardness Tester.

A Rockwell Hardness Tester is used to measure the hardness of materials, specifically how resistant a material is to deformation under load.

Multiple measurements are taken on each part to confirm that hardening has been applied correctly and consistently across critical areas. This process is essential for parts such as valves, piston pins, cam followers, crankshaft and camshaft journals, valve seats, and more – components where durability and wear resistance are key to performance.

LEEB HARDNESS TESTER

The Leeb hardness test is a method used to determine the dynamic hardness of metals. It works by measuring the rebound of a small impact body against the surface of a material – giving us quick, reliable results. One of the key advantages of this tester is its portability. We use the Leeb Hardness Tester for some of our larger items such as crankshafts and camshafts.

SURFACE FINISH MACHINE

The Surface Finish Machine allows us to test the quality of the surface of rollers, and test liners to ensure they have the correct grooves for oil retention. These components operate under constant friction, so achieving the correct surface finish is critical to engine performance and longevity.

A smooth, properly finished surface helps reduce wear, improve sealing, and ensure efficient operation inside the engine. Using precise measurements we verify that the liners and rollers meet the required standards – minimizing friction and extending service life.

Watch how we inspect and control surface quality to make sure every component performs exactly as it should.

KMP BRAND PISTON DRAWING

This is an example of a KMP Brand Piston Drawing. In order to be approved, this drawing has been compared to OEM. The OEM Piston was measured using the CMM (as seen in the previous slide) and the recorded measurements will have been compared to the drawing. Any corrections needed will have been identified and altered in order to ensure that the drawing is representative of the OEM piston, at which point the drawing can be approved. After approval, a production sample will be manufactured and analysed by the Quality Department to ensure that the sample is in line with the approved drawing on record. Both the approved drawing and sample are now held in our library as a point of reference.

DIGITAL VERNIER HEIGHT GAUGE

In order to ensure measurements are taken on a flat surface, KMP use a Granite Surface Plate which allows quick accurate readings when using the digital vernier height gauge. This is most used when completing delivery checks.

CRANKSHAFT AND CAMSHAFT ANALYSIS​

To measure the journal diameters of crankshafts and camshafts, multiple readings are taken at different points using a digital micrometer. For an accurate reading, an average is taken of the points recorded. The digital micrometer has a resolution of 1 micron. An engine hoist is used to manoeuvre the larger components to ensure all KMP products are measured.
