LONG JYI Machinery Co., Ltd. was founded in 1983, professionally manufacture mechanical presses for over 30 years and well- known with good reputation in press manufacturers in Taiwan. We create press machines with innovative advantages, such as Knuckle joint press with link motion drive, Fix the Link rods and control arms on both sides, Optimum slide motion, Human machine interface, Tonnage monitor…etc. LONJI press machines are very Different from other manufacturers.

President C.C.Lin insists the mission to keep providing quality press in the competitive markets. Our professional design system can apply 3-D dynamic simulation to ensure the most efficient and smooth-running mechanism, via precisely calculating the stress yields at every portion of the frame and avoiding cut off at those portion with high stress yield to ensure the rigidity of the frame, consequently our press machines are all with high rigidity, low deformation, low malfunction rate and increasing the durability of the machines. Many of our customers save lots of capital and Down cost after using LONJI press.

For products improvements and strengthen key technologies, LONJI R&D team keep Advance researching for customers, ex: with an innovative hybrid drive mechanism of combining knuckle join and link motion to achieve an optimal slide motion curve for precision progressive cold forging and near net shaping, the new KD series are with two or three-point effort force to make slide more evenly and reduce the eccentric load…etc. Our efforts to create higher quality press, better and safer working environments are continuous and without hesitation.

Nowadays, LONJI press’ application fields are including electronic parts, auto parts, motorcycle parts, bicycle parts, hand tools and garden tools in many countries, such as China, Korea, Thailand, Russia…etc. When you choose LONJI Press, you get the right choice.
