Production Process
The castings of valve cover/bonnet are manufactured by automatic production line, with shell moulding cores. Thus, the
large-scale, elaborate and high quality production is realized. Then through efficient machining and rigorous inspection, OEM valve series products would be eventually obtained with good surface quality, high dimensional accuracy, precise weight and optimal comprehensive performance cost ratio.
Before product development, we will evaluate and highlight the technical requirements of the valve cover/bonnet, including: material, surface treatment, hardness, weight, important technical requests and customer's special requests. Meanwhile, we will establish files for each customer, including: technical documents, communication records and the time of technique requests changes, this will help us to provide guarantee for product inspection.
