The making of world-class quality wheels
PAWI manufactures Rota wheels in accordance with high international standards to which we are committed. From design to casting, from machining to testing... every step of the way is a process of precision and thoroughness, backed by state-of-the-art technology. The process can be simplified into six steps.
Step one - A continuing research and development program
PAWI ensures that it is abreast with the latest trends and technologies by sending key personnel on specialized trainings and seminars geared toward productivity and quality improvement. In addition, PAWI designers are equipped with a comprehensive and sophisticated design validation software which uses a wide range of analysis capabilities such as nonlinear, dynamics and composites to assure its customers the best of both worlds; that is by striking a balance between good looks and road performance.
Step two - Product designs in tune with world trends and ever-changing motorists' preferences
By regularly participating in international automotive exhibits such as the SEMA show in Las Vegas, Nevada, USA and the Automechanika show in Frankfurt, Germany plus some top local exhibits, PAWI gets a feel of the latest international and local trends including the best selling wheel designs and accessories. From these inputs, our design team is able to come up with totally new or modified, mixed and matched concept designs from which the selection process begins.This complements the painstaking yet worthwhile design reviews to ensure that the every detail is covered.
Step three - Superb casting at its best
From the delivery of the pure aluminum virgin ingots up to the casting and heat teratment processes, Rota wheels are subjected to top-of the-line quality checking to ensure that only good castings are churned out. Starting with the chemical analysis test to ensure that only the prescribed A356.2 aluminum alloy are being poured into the moulds, the casted wheels then undergo x-ray inspection, vacuum test and finally heat treatment to ensure that the required molecular grain structure and hardness ratings are obtained.
Step four - A finshing process as thorough as anything you've seen
Our machining process uses the latest Computer-Numerically Controlled (CNC) horizontal and vertical lathe machines which are programmed to perform cutting operations hence providing accurate dimensions that are within the standard tolerances. A Coordinate Measuring Machine (CMM) is used to validate the CNC machines' output by generating a more precise measurement of up to three decimal places. The finishing painting process in turn features an automatic metal treatment preparation using several degreasing, pickling, chromating and multi-rinse zones and a conveyorized electrostatic painting system that produces a classy, impeccable paint job.
Step five - A tough and uncompromising inspection system from start to finish
To ensure quality is always at its best, each critical process is checked starting from the delivery of the virgin aluminum ingots up to the packaging process. At the penultimate process which is the final inspection, each wheel is meticulously checked for any paint or metal abnormalities then functionally checked for the correlation between the lug holes and the center bore. Finally, fitment checking is done on all wheel accessories that go with it.
Step six - The most rigid and exacting testing methods
To validate the road worthiness of all ROTA wheels, they are subjected to batch destructive testings which simulates actual driving and road hazard conditions such as impact 13, 30 and 90 degree testings and the dynamic cornering and dynamic radial fatigue test machines. For its paint performance testings, wheels are subjected to color matching, corrosion, adhesion, hardness, water/solvent/gasoline/brake fluid resistance, heat resistance and impact testings to ensure optimum paint quality that is guaranteed to last way beyond its warranty period.
