3. Incoming Quality Control
To establish the AQL acceptable level of incoming material control, to provide the material for the whole inspection, sampling, immunity. On the acceptance of qualified products to warehousing, substandard goods to take return, check, rework, rework inspection; responsible for tracking bad, to monitor the supplier to take corrective
measures to prevent recurrence.
4. Process Quality Control
The manufacturing site of the first examination, inspection and final inspection, sampling according to the requirements of some projects, judging the quality change trend;
found abnormal phenomenon of manufacturing, and supervise the production department to improve, eliminate the abnormal phenomenon or state.
5. FQC(Final QC)
After the manufacturing department will complete the product, stand in the customer’s position on the finished product quality verification, in order to ensure the quality of
customer expectations and needs.
6. OQC(Outgoing QC)
After the product sample inspection to determine the qualified, allowing storage, but when the finished product from the warehouse before the formal delivery of the goods, there is a check, this is called the shipment inspection.Check content:In the warehouse storage and transfer status to confirm, while confirming the delivery of the
product is a product inspection to determine the qualified products.
7. Certification.

Role of Continuously Variable Transmission (CVT) Gearbox
The role of a Continuously Variable Transmission (CVT) gearbox is to provide a seamless and infinite range of gear ratios to optimize engine performance and fuel efficiency. Unlike traditional gearboxes with fixed gears, a CVT uses a belt or chain running between two variable-sized pulleys. By adjusting the pulley diameters, the gear ratio can be continuously varied to match the engine’s power output and the vehicle’s speed.
CVTs are designed to keep the engine operating at its most efficient RPM range, resulting in better fuel economy and smoother acceleration. They eliminate the need for discrete gear shifts, providing a smooth and uninterrupted power delivery. CVTs are commonly used in automobiles, especially in hybrid vehicles, compact cars, and scooters, where optimizing engine efficiency and providing a comfortable driving experience are essential.
Potential Drawbacks and Limitations of Using a Variable Gearbox
While variable gearboxes offer many benefits, they also come with certain drawbacks and limitations:
- Complexity: Variable gearboxes can be more complex than traditional gearboxes, which can lead to increased manufacturing and maintenance costs.
- Learning Curve: Users, especially drivers new to variable gearboxes, may need time to adjust to the continuously changing gear ratios and driving characteristics.
- Efficiency at Extremes: Some variable gearboxes may not perform optimally at extreme power levels or high-speed applications compared to fixed-ratio gearboxes.
- Heat Generation: In some cases, variable gearboxes can generate more heat due to the continuous slipping of components, which may require additional cooling measures.
- Manufacturing Complexity: The design and manufacturing of variable gearboxes can be more intricate, leading to higher initial costs for production.
- Wear and Tear: The components involved in variable gearboxes, such as belts and pulleys, can experience wear and tear over time and may need more frequent replacement.
- Compatibility: Variable gearboxes may not be compatible with all types of engines or applications, limiting their versatility.
- Maintenance Requirements: Variable gearboxes may require specialized maintenance procedures and specific fluids, adding complexity to servicing.
- Environmental Concerns: Some variable gearboxes may use materials or technologies that have environmental implications, such as the disposal of transmission fluid.
It’s important to weigh these limitations against the advantages of variable gearboxes to determine whether they are the right choice for a particular application.
Improving Energy Efficiency with a Variable Gearbox
A variable gearbox, like a Continuously Variable Transmission (CVT), can enhance energy efficiency by allowing the engine to operate at its optimal RPM range, irrespective of the vehicle’s speed. This eliminates inefficient gear changes and reduces the engine’s workload during acceleration. The CVT’s stepless gear ratio adjustments enable the engine to maintain a constant and efficient power delivery, resulting in better fuel economy. Additionally, the CVT’s ability to adapt to different driving conditions ensures that the engine operates at the most efficient RPM, further contributing to fuel savings.
