From the first industrial revolution to the modern industrialization level of continuous development and growth, China's automobile manufacturing industry has achieved the leap from weak to strong, so far Chinese enterprises manufacturing industry accounted for more than 50% of the total global sales, the automobile industry as a symbol of the development of the country's industrial technology level, but also the crystallization of high-tech bearing, its wide range of technology, the number of other industries is difficult to compare. From the concern for new energy cars, to the support of independent brands, the development of China's auto manufacturing industry into the post-industrial development era has laid a solid material foundation and industrial strength.

As a product of modern industry, we are all curious about how the car manufacturing is produced. Automobile manufacturing process mainly involves stamping process, welding process, painting process, assembly process, commonly known as the "four processes" of automobile manufacturing, stamping plate using low carbon steel, car sound skeleton parts and coverings with steel plate stamping, in order to prevent rusting in different parts of the body using galvanized steel, such as the roof cover, etc., in the bearing force In order to prevent rusting, galvanized steel sheets are used in different parts of the body, such as the roof cover, etc., and high-strength steel sheets are used in the parts that bear greater force, such as the radiator support beam. Stamping dies are used to shape the material in a certain way with its specific shape. A model requires about 2000 sets of stamping dies, and nearly 300 sets of large and medium-sized stamping dies. The main parts of the assembly workshop are the front surround assembly module, the instrument panel assembly module, the lamp assembly module and the chassis assembly module. With the development of science and technology, the traditional process can not meet the upgrade of superior precision and quality, automotive intelligent manufacturing gradually become the national new energy strategic needs, and its industry development has two trends: high precision and tighter tolerances to improve operational efficiency and increasing electronic and electrical control engineering and low carbon, environmental protection. Etching process technology as a latecomer to China's development, but also in the breeding; automotive internal precision instruments, automotive horn mesh, sealing gaskets, injector filters and other high-precision, micron-level tolerances; through the forging of the etching process, so that the product is not only the display of technology, but also an art of excellence in the pursuit of the presentation of the etching process gradually play its high-precision, micron-level tolerance quality status.

Zhuolida etching process set precision etching, electroplating, electrophoresis, anodic oxidation, precision electroforming, vacuum diffusion welding as a whole, based in South China has many years of experience in etching, with imported materials as the main, can be etched on different materials, thickness from 0.03mm-2.0mm; tolerance can be controlled to a minimum of ± 0.01mm, can meet the precision of automotive parts to achieve tolerance micron level. Zollida etching process in the automotive field its products involve mechanical parts, gaskets and spacer gaskets, automotive horn mesh, high-performance gaskets, filter screens, fuel injectors, airbag components, cylinder head gaskets, clutch components, metal atomization sheet and new energy electric vehicle fuel cell sheet and other successful cases.
