LONJI PRESS CONCEPT (2D 1A)

Long Jyi Machinery Co. Ltd., (hereinafter referred to as LONJI Press) professionally manufacture mechanical press for over 30 years and keep well-known with good reputation among metal stamping fields. LONJI Press, adopted Differentiation, Down-cost maintenance, and Advance research concept, developed “Knuckle Joint Press with Link Motion Drive” which combined the advantages of single crank press, knuckle joint press and link motion press.

DIFFERENTIATION
Knuckle Joint Press with Link Motion Drive has several innovative advantages, such as optimum slide motion, human machine interface, tonnage monitor… etc.. LONJI press machines are very Different from other manufacturers. The series is good for cold forming, cold forging, complex forming processes, near net shaping and fine blanking, especially thick metal plate processing.

DOWN COST
To ensure the most efficient and smooth running mechanism, we designed via precisely calculating the stress yields at every portion of the frame and avoided cutting off at those portion with high stress yield to make sure of the frame rigidity. 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.

ADVANCE RESEARCH
For product improvements and strengthen key technologies, the LONJI R&D team keeps Advance researching for customers, ex: with an innovative hybrid drive mechanism of combining knuckle joint and link motion to achieve an optimal slide motion curve for precision progressive cold forging and near net shaping.. Creating a higher quality, better press and safer working environments are our continuous and without hesitation efforts.

LONJI PRESS, YOUR RIGHT CHOICE
Nowadays, LONJI press can be applied on electronic parts, automobile parts, motorcycle parts, bicycle parts, hand tools, garden tools, medical tools, metallic net and other hardware parts on the global wide. As you choose LONJI Press, that’s your right choice
