spring steel wire, we collect a lot of information. The customer complains are focus on the spring steel wire's surface, the dimensional accuracy and so on. We convene the staff to find the solution, fortunately, we have work out the improve measures which are fit the produce reality and feasible.
With the problem of spring steel wire's evenness, we put forward the measures: improve the transmission accuracy of draw bench; reform the diaphragm capsule; fish out a series of method of adjusting the diaphragm capsule through observing the spring steel wire on the draw bench.
With the problem of strength uniformity of spring steel wire, at the time of ensure the spring steel wire's quality, we also should do as follows: enhance the temperature control of heat treatment; adopt the Straight wire drawing machine;
With the problem of spring steel wire’s surface status, we can adopt these measures: develop the produce of spring steel wire, supply two kinds of steel wires with different surface status for customers to chose; do the technology service work, introduce to customer that some wrong operates will affect the surface.
The quality of spring steel wire after the measures have improved, we will insist on these measure and try other improvement measures to improve the spring steel wire’s quality continuously.
