Vehicle Turbochargers – Quality Control
Niitsu Turbo Industries always ensures consistent quality even though in mass production. We enforce the strictest policy and detailed steps in each and every manufacturing process.
All of our engineers and staff are well trained before they are assigned to their daily tasks and only qualified engineers are allowed to be in the manufacturing team, which will include drawing of turbocharger using CAD/CAM software, designing of the mould and tooling, machining, balancing and assembly line.
At the assembly plant, all engineers will thoroughly check the wheel sizes for both compressor and turbine wheel. The inducer and exducer of the wheels are then checked again using OE housings to ensure interchangeability. With this, the profiles of the wheels are also guaranteed correct according to the OE standard.
Meanwhile in the Quality Control department, all compressor housings and turbine housings are checked and tested again to ensure correct hole sizes for fitting purposes. Niitsu Turbo Industries engineers will also check for any porosity, corrosion, uneven surface, blockage and also poor material. If any of these are found on the housings, Niitsu Turbo Industries will strictly reject these goods. Only perfect and high quality goods will leave Niitsu Turbo Industries warehouse to be shipped to our customers. We will also check the actuator and waste gate to ensure our products do not suffer any loss of power or over boosting during turbocharger's lifespan.
A special room is used for the testing of the actuator with the correct pressure and boost. As the actuator is very critical towards a turbocharger’s performance, Niitsu Turbo Industries engineers will check the reading twice to ensure the performance of the turbocharger. Subsequently, we will also ensure that all aspects of the turbochargers including rotor assembly processes are well balanced to factory specification. The elimination of oil or water leakage in water-cooled bearing and tools are used to endure the quality and the tolerance labels of the turbocharger. Lastly, once the product is ready to be shipped out from the plant, all Niitsu Turbo Industries products are attached with a serial number to enhance our brand as well as for the product protection purposes.
Niitsu Turbo Industries began manufacturing turbochargers products under the leadership of our principal who has many years of experience from an OEM company. Thus, we can ensure and assure our customers that every detail and technical steps produced at Niitsu Turbo Industries are according to OE standards. All Niitsu Turbo Industries turbochargers part numbers are produced to match the OE data, be it the wheel sizes, hole sizes and thread, oil inlet and outlet, actuator pressure and orientation. We also always strive to improvise the cons of the OE turbo.
At Niitsu Turbo Industries, we are trustworthy and we will deliver the goods to you as promised and we are always on time. Our production period is quick and we have a wide range of available part numbers in ready stock and we will continue to develop more part numbers in time to come.
Our turbochargers are engineered with excellence, venturing towards OEM turbocharger yet it can be purchased with an affordable price. We take into account the key factor behind Japan's prominence on the international stage as our manufacturing in quantity.
