1.The wholesale and retail industry of metal plate

Jinjiarun has developed a variety of models with keen insight to provide the most efficient solution support for customers with wholesale and processing demand.

We provide high efficiency and precision finish processing for plates from major steel mills at home and abroad such as Mittal Steel, Arcelor, Baosteel, Tiangong, Xinyu, Dalian, Fushun, etc.

2.The milling and grinding process industry of metal plate

Our machines are widely applied to the milling and grinding process industry for molds,

The finishing metal plate is processed on four sides and six-sided to ensure parallelism, squareness and perpendicularity tolerance. High-precision milling can ensure product accuracy within 1 wire, which avoid the grinding process.

3.The mould bases industry

The CNC double-side milling machine performs fast milling on the four sides of the standard mold base as large as 1.2 meters and as small as 15 series instead of grinding.

The traditional grinding machine processing in the mould bases industry has gradually been eliminated, and the leading companies including Longji have begun to adopt the CNC twin head milling machine on a large scale for the mass production of standard mold bases

4.Hydraulic

It replaces the traditional manual duplex milling method in the field of hydraulic and oil block, high-efficiency milling, automatic detaction and positioning and automatic cuting from rough milling to finish-milling

Height can be selected from 200, 250, 300, etc. At present, hydraulic leading enterprises in Guangdong and Zhejiang areas have begun to use CNC twin head milling machine

5.Accessories

Large-scale machining of molds and mechanical parts such as wear blocks, inserts, and elastomers is more efficient than large workpieces. Once the clamping is completed, the four sides of the entire workpiece can be processed and the finished product can be quickly released.

6. Non-ferrous metal processing

Non-ferrous metals and alloys such as aluminum plates, copper plates and lead plates are processed with high precision and good finish. Hydraulic clamping is very easy to use. 

7. Other:

Castings, graphite, pump valves and other industries are also using our equipment to produce high precision products.
