  Mission statement |  Quality System
  • Measuring our performance in areas which contribute to our customer’s competitiveness.
  • Creating systems which allow us to repeat sucess with minial variance.
  • Discovering ways to work more efficiently, in order to increase value to customers with the least cost.
  • Treating every customers and employees with respect and diginity, recognising that people are the key to our success.
  •  Quality System
    ISO 9001: 2008 TS 16949: 2009 ISO 14001: 2004
     Quality Service = Quality Products
    Investment Casting, Precision Casting, Cast Steel Casting
          At casting products, customers receive our complete attention. All of our efforts are directed to make sure that customers needs are completely satisified. If the way we work is not quite fit the way you work, we’ll adjust accordingly. If customers have unexpected problem or special request, we will take extra effort to handle it quickly and efficiently.

          At longxing, quality control is an active, not reactive, function of manufacturing. Quality assurance starts the minute raw materials come in the door and continues through every stage of the casting process. We achieve part-to-part consistency, so the last casting is the same high quality as the first.

          All our manufactures have quality control systems consistent with ISO9001:2008 and TS16949:2009 quality control systems.Continuing statistical process control and process capability improvement is applied for all products manufacturing process. Our commitment and continuous effort in improving product quality has established our image as a high quality manufacture and supplier.

          We aim to be world class, committed to customer satisfaction & to encourage the spirit of leadership amongst our dedicated team by creating a healthy environment for continuous growth, profit and prosperity.
