Material Expertise and Process Control

Bending sheet metal is governed by material mechanical properties—yield strength, tensile strength, elongation, and anisotropy—along with thickness, grain direction, and surface treatment. Savegen’s engineers apply material science knowledge to predict and control forming outcomes:

Springback Compensation: Springback, the elastic recovery after forming, varies by material and requires angle over-bend or die compensation. Savegen employs empirical data, finite element analysis (FEA) when necessary, and historical process capability to program precise compensation for each material and geometry.

Bend Allowance and K-Factor Selection: Correctly calculating bend allowance and using appropriate K-factors ensures final part dimensions meet design intent. Savegen adapts these calculations for different materials, thicknesses, and bend radii.

Grain Direction and Anisotropy Considerations: For some materials, bending across or along the grain affects crack propensity and final geometry. Savegen advises on blank orientation to minimize risks and improve part performance.

Surface Finish and Handling: For visible components or plated parts, surface protection, low-contact fixturing, and appropriate lubrication strategies prevent scratches and marring during bending. Handling procedures and packaging are established to preserve finish integrity to delivery.

Design for Manufacture (DFM) and Engineering Support

A key differentiator for specialized sheet metal bending providers is the ability to guide customers in designing parts that are efficient to produce, maintain required performance, and are cost-effective. Savegen offers engineering collaboration and DFM advice covering:

Bend Sequence Optimization: Determining the order of bends to avoid collision, ensure accessibility, and minimize springback accumulation. Proper sequencing can reduce tooling changes and secondary operations.

Minimal Tool Changes and Standardization: Recommending design modifications to use standard dies or to combine features so that parts can be formed with fewer tool setups, lowering per-piece cost for medium- and high-volume runs.

Corner and Tab Design: Guidelines on bend radii, reliefs, hem types, and tab geometry to prevent cracking while satisfying strength and assembly requirements.

Material Selection: Recommending materials that balance weight, corrosion resistance, strength, and cost while ensuring good formability.

Prototyping and Iterative Development: Rapid prototype runs to validate designs, test fit-up, and refine tolerances before committing to production tooling investments.

Quality Assurance and Inspection

Consistency and traceability are critical in precision bending. Savegen employs structured QA processes:

In-process Monitoring: Use of angle sensors, displacement sensors, and iterative test bends to validate bend angles and dimensions during set-up. Automated or manual measurement checks at specified intervals maintain process control.

Metrology and Inspection: Coordinate measuring machines (CMM), optical comparators, laser scanners, and contact gauges are used to verify critical dimensions, hole locations, and form accuracy. For high-volume runs, statistical process control (SPC) tracks key metrics and signals drift before out-of-tolerance parts are produced.

Documentation and Traceability: Material certifications, process parameters, tooling identification, and inspection records are maintained to support audits, warranty claims, and regulated industry requirements (e.g., aerospace or medical where applicable).

Continual Improvement: Root-cause analysis, corrective action tracking, and tooling lifecycle management ensure ongoing improvements in yield and reductions in scrap.

Ancillary Services and Value-Added Capabilities

To offer a full-service solution, Savegen integrates bending with adjacent fabrication capabilities:

Cutting and Blank Preparation: Laser cutting, plasma cutting, or turret punching for blanks with tight tolerances and consistent hole placement.
