Tenders are invited for Comprehensive Maintenance Contract To Carry Out Maintenance Work Of Cnc, Welding, 3D Cmms And Stretch Forming
Machines At Aerospace Division For A Period Of Two Years As Per The Scope Of Work In The Tender Document
The facility possesses a comprehensive suite of capabilities to manufacture sheet metal parts and assemblies, such as CNC routing, automatic deburring, brake-press forming, stretch forming
, hydro-forming, heat treatment, a fully-automated surface treatment line and over 9,000 sq.
Additional capital improvements at the LMI facility in Vista, California, have provided the necessary capacity for the program's stretch forming
and metal fabrication requirements.
This reduction shows the gradual transition of forming mode from stretch forming
to draw forming for this point.
is a metal forming process in which a piece of sheet metal is stretched and bent simultaneously over a die in order to form large contoured parts (Paulsen and Welo, 2002).
Taking into account that the shape is relatively complex, we decided that the tangential stretch forming
method is most suited.
: Stretch forming
forces tapered dies into the top and bottom of the can.
Systems have been developed for the stretch forming
and casting industries.
Haydn Risby, technical manager at HAT, said: "The traditional method of stretch forming
was offered initially, but for the low to medium production volumes required by Modec, the stretch forming
tooling costs were not cost effective for the project's budget.
And Schweizer backs up its production people with computer-aided design (CAD), computer-aided manufacturing (CAM), and computer numerical control (CNC) routing plus stretch forming
, rubber press forming, drop-hammer forming, aluminum heat treating, and welding.
Sheet forming: blanking, piercing, pressing, deep drawing, spinning and flow turning, stretch forming
, fluid and rubber forming, high-rate forming processes, welding, etc.
The plant's component production capabilities include CNC routing, automatic deburring, brake-press forming, stretch forming
, bladder-press forming and heat treatment along with a fully-automated surface treatment line with large 4 m tanks.
