Mold Present Status of Technology
Technical level of China's mold industry currently uneven,Cnc machining with wide disparities. Generally speaking, with the developed industrial countries, Hong Kong and Taiwan advanced level, there is a large gap.
The use of CAD / CAM / CAE / CAPP and other technical design and manufacture molds, both wide application, or technical level, there is a big gap between both. In the application of CAD technology design molds, only about 10% of the mold used in the design of CAD, aside from drawing board still has a long way to go; in the application of CAE design and analysis of mold calculation, it was just started, most of the game is stillin
trial stages and animation; in the application of CAM technology manufacturing
molds, first, the lack of advanced manufacturing equipment, and second, the
existing process equipment (including the last 10 years the introduction of
advanced equipment) or computer standard (IBM PC and compatibles, HP
workstations, etc.) different, or because of differences in bytes, processing
speed differences, differences in resistance to electromagnetic interference,
networking is low, only about 5% of the mold manufacturing equipment of recent
work in this task; in the application process planning CAPP technology,
basically a blank state, based on the need for a lot of standardization work;
in the mold common technology, such as mold rapid prototyping technology,
polishing, electroforming technologies, surface treatment technology aspects of
CAD / CAM technology in China has just started.
Computer-aided technology, software development, is still at low level,
the accumulation of knowledge and experience required.
Most of our mold factory, mold processing
equipment shop old,Cnc machining long in the length of civilian service, accuracy, low
efficiency, still use the ordinary forging, turning, milling, planing,
drilling, grinding and processing equipment, mold, heat treatment is still in
use salt bath, box-type furnace, operating with the experience of workers,
poorly equipped, high energy consumption.
Renewal of equipment is slow, technological
innovation, technological progress is not much intensity. Although in recent years introduced many
advanced mold processing equipment, but are too scattered, or not complete,
only about 25% utilization, equipment, some of the advanced functions are not
given full play.
Lack of technology of high-quality mold design, manufacturing technology
and skilled workers, especially the lack of knowledge and breadth, knowledge
structure, high levels of compound talents.
China's mold industry and technical personnel, only 8% of employees 12%,
and the technical personnel and skilled workers and lower the overall skill
level. Before 1980, practitioners of
technical personnel and skilled workers, the aging of knowledge, knowledge
structure can not meet the current needs; and staff employed after 80 years,
expertise, experience lack of hands-on ability, not ease, do not want to learn
technology. Cnc machining In recent years, the brain
drain caused by personnel not only decrease the quantity and quality levels,
and personnel structure of the emergence of new faults, lean, make mold design,
manufacturing difficult to raise the technical level.
