FOCUS ON STAMPING

Swiss stamping specialist , Bruderer AG , offers its BSTA range of presses with press forces from 180 to 2500kN and a stroke speed range of 100 to 2000spm . The lever system distributes the load acting on the ram in the system .
“ This load distribution , the minimal bearing clearances and the efficient lubrication system are the main reasons for the long life and consistently high precision of our stamping presses ,” it told ISMR .
At the Blechexpo 2021 exhibition in Stuttgart , it ran a complete stamping line firing out 500 round socket contacts per minute . Bruderer employs some 460 people all over the world , 370 of whom work at the Frasnacht site in Switzerland , where all its stamping presses are produced . Bruderer UK celebrated its 50th anniversary in 2018 and offers high-speed stamping presses and pre-owned presses as well as other presses , ranging from six to over 4,000 tons . It also offers a range of servofeeders , decoilers , rewinders , welders , conveyors and lubrication equipment .

Taiwanese manufacturer Chin Fong ’ s stamping presses range from 20-ton single crank presses and up to 3200 metric tons of capacity to 4-point eccentric gear-driven , large panel and multi-stage transfer presses . Forging presses are further diversified by cold , warm and hot forging processes . It has also developed an intelligent single-crank press with a crank mechanism used for blanking , drawing , bending and partial forming .
Chin Fong now has offices in Taiwan , China , Indonesia , Malaysia , Thailand and the USA as well as representatives in numerous countries around the world . Its A0 tandem press line for the automotive industry includes stages such as deep drawing , following by trimming , piercing etc .
Chin Fong ’ s straightside double crank power press , with 400-ton capacity , has a bed area of 2.5m x 1m and can produce metal stampings from material measuring up to 400mm wide and 3.5mm thick . It has a variable speed of between 30-50 strokes per minute and a maximum shut height of 450mm . In 2020 , its iForming PMS ( productivity management system ) won the 29th Taiwan Excellence Award .
DEES Hydraulic Industrial Co ., Ltd . is a hydraulic press manufacturer with factories in Taiwan and China . Its main products include presses such as custom triple-action ; die-
DEES HD 2500 tandem line with robotic arm feeder .
spotting ; die tryout ; deep-drawing ; transfer ; servo-controlled ; tandem line ; hot forming 4-post ; hemming ; C-frame etc . Its focus is on three main stamping areas ; servo motors , higher speed of the hydraulic press and higher productivity for presses , using accumulators for shorter strokes . DEES Hydraulic has also successfully developed a closed loop , hydraulic , servo-controlled die spotting press .
Formed in 1976 in Taiwan , it has been present in China since 2000 and , in 2014 , moved to a newly built factory in China , which is almost double the size of its previous factory there . The automotive market is a key industry sector for the Taiwanese manufacturer , which supplies customers such as Audi ; Volkswagen ; Mercedes-Benz ; Volvo ; HONDA ; TOYOTA ; BMW and more . For the past 44 years , more than 4,500 machines and 45 tandem lines from 5 to 6,000 tons have been built and exported to 75 countries in the world .
Fagor Arrasate , headquartered in Spain , designs and manufactures presses and stamping systems from 630KN up to 150,000KN , using mechanical , hydraulic or servo-driven technology , depending upon customer requirements . New solutions for large transfer presses of above 30,000kN of force to process tailored blanks , HSS and UHSS , were launched in November 2021 .
It recently incorporated Danobat ’ s coil laser cutting technology into its press lines . Both companies expect the new laser cutting lines to contribute additional annual sales of between ten and fifteen million euros by 2024 . With an eye on Industry 4.0 , it brought the Digital Twin of an existing 2000-ton press to the Blechexpo exhibition last year to show different applications of the model in training , maintenance or commissioning .
In May 2022 tests with Mondragon Unibertsitatea and Batz S . Coop , Fagor recently demonstrated that the weight of a vehicle bumper can be reduced by 40 % by using hotstamped aluminium .
Fresan Makina san . ve Tic . Ltd . Sti manufactures C-frame eccentric presses from 10 tons to 250 tons ( 100kN - 2500kN ), special machinery and hydraulic punching presses .
