Customer service

AKO Machinery adheres to the service tenet of "customer first, service first" and regards customer service as a key part of the company's development. While improving product quality, it constantly improves service quality and continuously improves service.
AKO Machinery adheres to the active service model and the “three-in-one” (professional, caring, timely) service concept, and always regards the customer as the source of survival and the source of development.
After-sales service is divided into technical services during the contract service period and technical services outside the contract service period. In general, the division of these two time periods is defined by the service period signed by the contract.
During these two different service periods, each engineer shall strictly abide by the terms of the AKO Machinery contract agreement or the service commitments in AKO Machinery 's relevant bidding documents, and arrange and deploy personnel to ensure the smooth operation of each equipment.
