5 things you need to know about high-tech stamping

1) Hot-forming presses tame ultra-high-strength steel and firm aluminum alloys.

Hot forming steel and alloys supports lightweight, high-strength car bodies and frames, components revolutionizing automotive manufacturing. DEES integrates Industry 4.0 technologies into hot forming, automating and collecting data with the transfer system.

DEES has successfully established hot-forming lines for certain high-strength steels, the most difficult materials to form, so lower temperature aluminum and other alloys will be less challenging. The technology has become increasingly common throughout Europe.

We expect the technology to become more common as DEES and other providers show how heat can shape high-strength materials, overcome post-forming bounceback issues, and provide accuracy for finished parts.

Carbon-fiber reinforced plastic (CFRP) composite materials are also popular for European manufacturers, and DEES has produced several composite hot-forming systems as well.

DEES provides solutions from designing and manufacturing presses to integrating tandem lines.

2) DEES recently added new production facilities for presses to support a growing global client base.

We expanded our second factory in late 2019. For the mid- to large-scale custom-made hydraulic presses (bolster >2,000mm x 2,500mm; force >500 tons), the old facility could complete 15 to 20 presses annually. Capacity is now 25 to 30 presses. For duplicates of existing small-press designs, we can produce 60 units in the 50-ton, 900mm x 600mm size class; 75 presses in the 150-ton, 1,000mm x 700mm range; and about 10 large-scale presses in the same year.

3) High-precision stamping advances.

DEES is developing higher accuracy presses using servo motors to form a flexible forming curve or stop the slide during deep drawing. Servo motors react faster than conventional motors on presses. For a hydraulic press, it’s not necessary. Constant development of advanced proportional valves, electrical programming, and components promote stable high accuracy, offering faster speed, quicker response, and variable speed controls.

For 2021, we seek to reduce costs by testing local (Taiwanese) suppliers instead of German or Italian suppliers.

We expect to increase ascending and descending speeds and shorten valve response time. Our die spotting presses achieve ±0.01mm accuracy. Electrical system improvements include advanced linear transducers that ensure accurate slide positions and maintain excellent accuracy and repeatability.

4) DEES continuously improves operations.

Automation and artificial intelligence (AI) technologies are becoming more popular, so we’ve added Industry 4.0 remote monitoring functions, history review systems, and program-fixing tools. Our R&D department is our core, and we invest 30% of earnings into product improvement.

5) Online exhibits allow manufacturers to learn about DEES’ capabilities.

For clients outside of Taiwan interested in learning more about us, we have used online marketing to exhibit new technologies. Recently, we added 720° virtual reality (VR) at https://www.deesgroup.com.tw/company_en.php?id=1746 to give companies a more immersive view or our capabilities.
