The interior/exterior decoration of luxurious building, the handrail of coach luxury coach, door, household utensil, workmanship, tourist souvenir etc..
Although China's ornament materials industry development is rapid, due to starting evening, starting point is low, on some sport technique segments with state
International standard is compared to also there is a big difference.Industry problems for a long time do not solve, not only affect Related product the market sales volume and
Usage experience, also serious such product that limits is in the market occupancy volume of international scope.It develops and industrialization has advance
The imitative billon of energy is the inevitable problem of decoration material field, and domestic many research institutions and enterprise carry out for a long time
Multi-faceted trial, but regrettably, not yet obtain the progress of any substance so far.Pass through advanced material
Material designing technique can innovate alloy material by the thermodynamics and kinetics means of bottom, and to developing and open
The problem of hair new material solves and industrialization has very big market value.Domestic and international market in face of being growing more intense competes,
Must accelerate restructuring paces, this is not only the needs of China's jewellery industry survival and development and world today's correlation neck
The development trend in domain.
