Strengths of SaNEI
  • 01
    Pursuing high quality through a thorough inspection system
    Q = Quality in QCD is the most important of the three elements. The purpose of a company providing a product to a customer is to solve the customer’s problem. If the quality of the output provided does not meet the customer’s requirements, the company will not be able to solve the customer’s problem with the product it provides. If you cannot solve the customer’s problem, you have not fulfilled the purpose of providing the product, and this will cause the customer to leave the company. For this reason, we have introduced the latest inspection equipment and a satisfactory inspection system, which has earned the trust of our customers.
  • 02
    Optimal production process realizes low cost
    C = Cost in QCD refers to human resources (man-hours) in addition to monetary costs. Cost is usually a factor that should be kept as low as possible. In order to reduce costs, it is necessary to devise ways to eliminate factors that increase costs. To this end, we identify and consider factors that increase costs, and realize optimal machining methods using CAD/CAM, 5-axis MC, horizontal MC, etc., to achieve costs that satisfy our customers.
  • 03
    80 units of equipment and a 20-hour-a-day operation system for speedy response
    D=Delivery date in QCD is an order received by respecting the desired delivery date based on discussions with the customer, and we will lose the customer’s trust if there is any delay.For this reason, we use 80 pieces of equipment and operate 20 hours a day to ensure delivery to the satisfaction of our customers.
