For automobile manufacturers, the speed, safety, and reliability of production equipment can often be decisive factors. Being able to produce automotive parts quickly while protecting manufacturing equipment from unnecessary wear and damage without compromising safety has become essential for efficiency. Stopping production due to damage to manufacturing equipment incurs repair costs. This issue can be resolved by adding or installing a "speed control gas spring" inside the mold. By eliminating unnecessary bounce in the press mold, it leads to an increase in the number of strokes per minute, resulting in improved productivity, providing an optimal balance. 【Benefits】 ■ Minimizes or eliminates bounce of the blank holder ■ Can minimize damage to the press mold ■ Allows for increased productivity through improved efficiency of part transfer ■ Can increase the number of strokes per minute in most applications ■ Easily retrofittable to existing molds *For more details, please refer to the PDF document or feel free to contact us.

With the evolution of the metal stamping industry, molds that align with this evolution will become necessary. When processing sheet metal through pressing, lateral movement occurs within the press mold. As a result, guide components will also be required within the mold as a countermeasure to prevent gas spring damage. To address this, we have begun the development of the "Flex Guide Solution." The Flex Guide is a unique guiding technology developed a few years ago with the aim of reducing gas spring damage and extending its lifespan. The Flex Guide can be considered an efficient solution that streamlines production. [Case Study] ■ Issues - Molds that align with the evolution are necessary - Guide components are also needed within the mold as a countermeasure to prevent gas spring damage *For more details, please refer to the PDF document or feel free to contact us.

A customer located in southern Sweden, a mass production manufacturer of metal paint cans and lids, relied on the maximum performance of the springs they used for production. The production volume, the quantity of both components, and the parts manufacturing and can manufacturing per minute were impressive, and since the demand for these products significantly exceeded that of automobiles and large home appliances, an approach to different mold designs and press specifications was necessary. Generally, companies that manufacture such products produce millions of parts weekly. Typically, the manufacturing process is highly automated and optimized for mass production. When the speed and accuracy of the molds are crucial, different designs, press specifications, and the use of gas springs are required compared to conventional molds. Usually, KALLER receives inquiries at this point and assists with cost-effective production. [Case Study] ■Challenge - When the speed and accuracy of the molds are important, different designs, press specifications, and the use of gas springs are necessary compared to conventional molds. *For more details, please refer to the PDF document or feel free to contact us.

The mold manufacturer was able to secure a large order for die cushion pin specification molds with the support of the KALLER Korea team. Initially, this order for their own use was hesitated due to the lack of press functionality necessary for properly operating and trialing the cushion molds at this mold manufacturer. This functionality generates mold cushion pressure as pad pressure and clamping force within the mold through an air or hydraulic-driven cushion integrated inside or underneath the press, rather than using conventional springs. Fortunately, thanks to KALLER Korea's design, manufacturing, and installation of the ram cushion plate, the mold manufacturer successfully avoided the costly investment of purchasing an entirely new press. [Challenge] Despite the need for a cushion press in the specifications for sheet metal mold orders, only standard hydraulic or mechanical presses are available. *For more details, please refer to the PDF document or feel free to contact us.*
