The benefits of utilizing the deep draw process characteristics include:
- The solid ram design of the US Baird Transfer Press makes possible the production of parts with high precision and fast running speeds.
- The tooling cost is typically lower than a progressive die due modular construction of the tooling.
- Standard materials can be drawn including CRS, Stainless Steel, Copper based alloys, Aluminum, HSLA, 17-7ph, as well as exotic material such as Niobium, Tantalum and Titanium.
- By utilizing an oscillating feed, blanks can be cut from the strip in multiple rows for best utilization of material.
- Because the part is cut free from the material strip all edges can be cut stamped or formed.
- The capability to maintain consistently close tolerances.
The incorporation of “dwells” in the construction of the cams (the “dwell” refers to a temporary stop in both part transfer and the vertical motion of the punch) allows for features normally done as secondary operations to be incorporated into the primary operations.
These include:
- Side piercing
- Side slotting
- Roll Threading
- Lettering
- Beading
- Embossing
- Debossing
|
- Rolling
- Knurling
- Skiving
- Dimples
- Bumping
- Lancing
| Other features that can be incorporated into the primary machine include:
- Step draws
- Reverse draws
- Necking
- Ironing
- Curling
- Shaped piercings
- Shaped clippings or trimmings
- Reconing
|
- Hydroforming (a process that uses liquid to create a shape in a single operation)
- Bulging
- Extruding or drifting
| The benefits of utilizing Stewart EFI for your deep draw applications:
- Engineering and design support to jointly design or redesign your component to minimize cost, maximize quality and facilitate the quickest and easiest application of the stamped component into your product. (VA / VE).
- Rapid Prototyping support for preliminary trial runs using production intent processes
- Extensive pre-production planning and analysis (APQP).
- Robust designs including precise strip and part control and utilizing design to cost principles.
- Dies are designed with modular and often interchangeable components to increase run sizes, reduce maintenance time and therefore minimize non-value added down time.
- Utilization of sophisticated electronic, mechanical, optical and magnetic sensors for die protection, defect detection and part measurement as well as integrated press monitoring systems to ensure part quality.
- Lowest total cost stamped components in the industry.
- Long term high quality consistency.
- Quicker response time and shorter deliveries.
- Extensive highly skilled and experienced technical and support staff.
- Tools guaranteed for life of part.
