Inspection and Sampling of Incoming Raw Materials.
Raw materials must be stacked with kraft paper between them, maintaining a certain distance between each metal part to ensure no friction or wear. For transportation and long-term storage, materials should be sealed with film.
Wear can lead to a decrease in product accuracy, while friction-generated metal particles and dust from the air can affect engine longevity and performance. Improper storage and transportation can impact engine performance as well.
Parts required for the day's production tasks will undergo ultrasonic pre-cleaning by the warehouse management personnel to thoroughly remove surface dust, oil stains, and metal particles, ensuring they are in optimal condition for dispatch.
Cleaned parts will be moved to a dedicated pre-assembly parts area, where they will wait to be introduced to the production line.
After the engine's main assembly is completed, it enters the testing room for a 20-40 minute trial run.
Quality inspectors conduct thorough testing and adjustments while completing the engine's internal final break-in, saving non-professional customers the hassle of changing the oil after the initial warm-up.
Drain the test run oil and perform a comprehensive cleaning of the engine's surface.
Perform the final assembly of components such as the fuel tank, air filter, and muffler. Additionally, check for any omissions or errors in previous assembly steps. Engines lacking process identification are returned for further inspection.
