Our Capability & Service & Quality Control
Abundant resources: we have worked closely together with tens of factories located in different provinces in China for many years. They are individually specialized in casting, forging, stamping, welding, machining, and other manufacturing processes. These suppliers are all certified with ISO9001:2001 Quality Control System, and have professional engineers and production equipments. We can meet the customer’s demands for different materials and structural shapes of the products.
Excellent ability for resource consolidating and organizing: the operation team with rich experiences and extensive social relationships can source and locate appropriate factories to proceed with and optimize the production according to the production and machining requirements of the products, to ensure the quality and minimize the costs and prices.
Strict supplier evaluation procedure: Our internal Suppliers Evaluation Procedure has been approved by our customers and the facts prove that it is a scientific and state-of-art procedure. We will choose the most appropriate factory to develop a certain project. Also we can evaluate the supplier with the customer’s evaluation procedure and issue an objective evaluation report.
Scientific QC system: we have an independent QC department and each step of a project is conducted by technical personnel with standard job procedure to follow up, supervise, and inspect, to avoid any possible quality negligence. Drawing dimensions are strictly measured, technical standards reviewed, production and machining processes optimized, and sample and the parts are inspected in detail before shipping. We strictly control product quality at each step to ensure the quality stability.
We implement PPAP procedure during the sample development stage, implement the Production Control Plan during the production course, and sample and evaluate the parts before shipment and issue reports to our customers. The suppliers will provide the qualified certification for all the goods we supplied, and each part will be traceable during the production.
After-sales service system: the after-sales service team is specially in charge of answering the questions raised by the customers and meeting the different customers’ demands. “Satisfy the customer” is our service tenet.
