Hanil KNUCKLE PRESS
General KNUCKLE PRESS
LINK MOTION PRESS
LINK-KNUCKLE PRESS
Use
Universal press molding Professional Cold Forging Drawing Specially designed to perform drawing and Cold Forging at the same time
Able to produce high-value-added precise parts
Universal press molding
Progressive Cold Forging
Highly efficient productivity
Strength
High productivity/ 2-3 times of universal Suitable for concentrated load of small-sized products Higher productivity compared to hydraulic press  
Uses "H" TYPE double skin steel on the side to prevent deforming frame
May hold larger molds as operating frame can expand and insert bolster  
Broad bolster for professional molding
Suitable for producing automotive parts  
Significantly decreases noise
 
Extends the lifespan of molds
 
Strong against Eccentric Load as Screw Point is in flat shape and maintains precision at Knuckle Press' Bottom Dead Center
 
Bottom Dead Center is long from 150° to 210° and shows the symmetric speed of Bottom Dead Center
 
Weakness
Cannot increase Slide Stroke over a certain level Reduces productivity (approx. 50 SPM) Reduces productivity and causes noise Cannot increase Slide Stroke over a certain level
Cannot install large professional mold Low capacity
Slide-controlling Screw Point is in the Ball shape and may be distorted by a small eccentric load to affect precision in Bottom Dead Center of Knuckle Press The slide to trigger link motion cannot be forged and is at high risk of mechanical damage and wearing in forced operation
Cannot form the speed curve for constant velocity in Bottom Dead Center due to the mechanical properties of link motion
Motivation
To improve the popularity and productivity of precise press as ordinary Knuckle Press lowers productivity and cannot hold large molds Small products' concentrated load forging To improve productivity when performing hydraulic drawing To improve the weakness of link motion and increase productivity by allowing drawing and Cold Forging
Professionally manufactured Knuckle Press since establishment to hold a number of patents
