90 years, Custom Mold manufacturer China entered
the period of rapid development, which greatly promoted the die steel
production and application technology. Through the introduction of advanced
equipment and technology, is capable of producing high quality mold steel, some
of the metallurgical quality of steel has reached the international advanced
level, and a small amount of exports, the international community to enjoy a
certain reputation.
It should be noted that China die steel
production and application of the overall level is still low, there are many
long-unresolved problem. injection mold china made the vast
majority of electric furnace steel, steel, steel composition segregation of
large, low purity, high carbon levels, loose-level exceeded, the module to the
performance of vertical and horizontal disparities.
Die steel materials utilization is low, because
the steel rod material in more than 85%, saw materials, changes in the
consumption of large forging; module, flat steel, sheet metal and other varieties of small, boutique, products
less. Change the effect of die steel forging poor, the vast majority only die
forging billet to change shape, size, purpose, ignoring organizational
improvement model that remains blank in the other carbides and negative super
streamline distribution.
Die material selection and application of improper
heat treatment of steel in the mold is a prominent problem. Custom Mold Design,
makers not familiar with the material and heat treatment,
heat treatment technology personnel are not familiar with the working
conditions of the mold, or heat treatment process often does not result in material selection and die
match.
In addition, the implementation of strict heat treatment, heat treatment
equipment and technology behind the mold caused by improper operation of deformation, cracking, is
universal.
Survey showed that the mold material selection and heat treatment
due to early failure caused by improper accounted for about 70%. Surface treatment in the Die
Casting Mold Design of the application, in addition to carburizing, nitriding,
other diffusion processing (infiltration non-metallic, alloying) rarely used,
less coating and spraying applications. Some applications also often due to
inappropriate choice of species and processes, achieving the desired effects,
and even not only useless but harmful, mold steel application technology to
become a weak link.
