Renowned creative master Stan Lai once said, “The ultimate achievement of creativity lies in whether one’s motivation can be shifted toward altruism.” In this spirit, LONJI Press has developed the Precision Forging – Toggle Link Press and the Precision Forging – Two-Point Toggle Link Press in direct response to customer needs—delivering machines with outstanding performance.
Stamping manufacturers prioritize high-quality output and cost-effectiveness. All LONJI press machines adopt a low-failure-rate mechanical design and utilize advanced computer software to calculate optimal link positions and driving angles, resulting in a fully optimized slide motion curve.
Compared to conventional toggle presses, the forming time is approximately 70% longer, enabling greater dimensional accuracy, preventing part deformation, and producing burr-free components with no fractured surfaces. According to actual user comparisons, tooling life is extended up to three times that of general-purpose presses.
In addition, the significant reduction in operating noise helps create a more environmentally friendly and comfortable workplace for customers.
In addition, this series is equipped with a digital tonnage monitor, allowing clear visibility of the applied tonnage during operation. When properly configured, it also functions as an overload protection system for the die, enhancing safety and safeguarding tooling from damage.
Mr. Lin, Chairman of LONJI Press, emphasized that this type of press costs less than 50% of a servo press, yet effectively eliminates the need for secondary processing and significantly reduces die maintenance costs. From a total cost-efficiency standpoint, investing in such presses proves to be more economical and delivers higher returns.
For continuous die production, in addition to standard specifications, LONJI offers customized solutions based on specific production needs—such as shortening the stroke length to increase stroke count, or expanding the bolster and slide width—to fully accommodate precision applications like automotive and motorcycle brake pads, computer components, mobile phone housings, and front and rear bicycle gears.
