FOCUS ON STAMPING
JIER press technology .
Established in 1937 , JIER Machine Tool , Ltd . is a large manufacturer of metalforming equipment and heavy metal-cutting machine tools in China . Other JIER products include press automation equipment ; sheet-metal processing machines ; foundry machinery ; CNC cutting machines ; environmental protection equipment and building materials equipment .
It has supplied hundreds of automated highspeed tandem lines globally . It also produces a variety of mechanical presses , from C-Frame to straight-sided press including transfer presses , progressive presses , blanking lines etc . Servo stamping solutions have also been provided to carmakers .
Komatsu designs large presses for forming automobile roofs and doors . Its large presses are represented by a tandem press for a variety of wide applications and a transfer press for high productivity . Its hybrid AC servo press , H1F , achieves high performance by combining advanced CNC controls and a hybrid drive mechanism ( pat . p ). Its large high-speed transfer blanking press for processing car body panels improves productivity by 75 %, it told ISMR . Komatsu also provides blanking presses and coil lines .
Since its foundation in 1863 , LASCO Umformtechnik GmbH has been engaged in harnessing fluid power for forming applications . It supplies machine tools and production lines for forming tasks and develops , designs and manufactures individual solutions for industrial users in more than 60 countries . This includes hydraulic presses for sheet-metal forming , deep drawing and coining presses as well as press automation . It offers a complete range of conventional forming machines for hot , warm and cold solid forming as well as sheet-metal forming , which are individually designed and automated according to customer requirements .
Its hydraulic deep-drawing presses are particularly suited for difficult drawn parts
and special materials ( press forces of 4,000- 40,000kN ). With its Multiplex press , the combination of servo-hydraulic press with integrated impact forming presents new possibilities in forging technology . It also supplies screw presses .
With the VPE / VPA series and numerous options , accessories and automation options , LASCO offers a press concept for preforming , trimming , piercing and upsetting operations ( 2500-100,000kN ). It has automated over 500 production lines .
Lien Chieh Machinery Co ., Ltd ( LCM ) custom-builds its hydraulic presses and is celebrating 76 years of operations ( hydraulic presses ranging from 50 up to 15,000 tons ). For more than seventy years , it has designed and developed a comprehensive range of technically advanced presses . It provides in-house manufacturing from start to finish :
An automated line with servo press ( Loire Gestamp ). cutting ; welding ; annealing ; CNC machining ; assembly ; quality assurance and factory acceptance .
With tonnages ranging from 2400 to 1000 tons and a bolster area of 5,000 x 2,500mm , its servo-mechanical tandem press line is used in the automotive sheet-metal industry . Designed to overcome the limits of traditional hydraulic presses ( in terms of speed etc .), the manufacturer launched its first servomechanical tandem line in 2016 . Its product portfolio also includes die spotting presses ; die tryout presses ; drawing presses ; forging presses ; hemming presses ; hydraulic presses and others .
Loire Gestamp , a branch of the Gestamp group , designs and manufactures all types of hydraulic presses and can adapt products to the specific needs of each project . Processes include hot stamping , cold stamping ( deep drawing presses ), hydroforming and try-out tooling .
Based in Hernani , Gipuzkoa ( Spain ), since 1962 , Loire Gestamp is one of Europe ’ s largest producers of hydraulic presses . Its machines are designed and built in accordance with its clients ’ technical specifications ( from 2,000 to 100,000kN ).
Loire Gestamp came into existence in 2011 following the acquisition of Loire Safe by the Gestamp group . It installed its first fully monitored servo-mechanical line at Gestamp Navarra plant in 2020 to ensure greater production and flexibility with lower energy consumption .
It also has internal capabilities for the development and manufacture of dies , covering the entire value chain : design ; machining ; construction ; tuning ; prototyping and monitoring . In this way , Gestamp keeps its stamping process experience in the group .
