Stamping Die Trim Steel Blanks

Stamping Die Tryout & Validation Services

New stamping dies require thorough tryout and debugging before entering production. Hebei Haoxinran Machinery provides comprehensive die tryout services on our tryout presses, ensuring your dies produce quality parts from the first production run.

What Is Die Tryout

Die tryout is the process of installing a new die in a press and running test stamps to identify and correct issues. During tryout, engineers adjust die geometry, clearances, and process parameters to achieve the desired part quality and consistency.

Tryout Process

Our systematic tryout process includes:

• Die Inspection: Visual inspection of die components before installation, checking for damage, proper assembly, and clearances.

• Press Setup: Installing the die in the tryout press, setting tonnage, stroke, and shut height.

• Initial Trial: Running the die slowly with test material to observe operation and identify obvious issues.

• Part Inspection: Measuring trial parts for dimensional accuracy, edge quality, surface defects, and springback.

• Die Adjustment: Making corrections to trim clearance, draw beads, radii, and other features based on part inspection results.

• Iteration: Repeating trial runs and adjustments until part quality meets specifications.

• Validation Run: Running multiple cycles to verify consistent quality and identify any wear or performance issues.

Common Tryout Issues We Solve

Typical problems identified and corrected during tryout include:

• Burr Issues: Adjusting trim clearance or re-grinding cutting edges to reduce burr height.

• Wrinkling: Adjusting draw bead pressure or blank holder force to eliminate wrinkles in drawn parts.

• Splitting: Adjusting draw radii, blank shape, or material flow to prevent material splitting and tearing.

• Springback: Compensating for springback by adjusting die geometry and over-bending.

• Dimensional Variation: Adjusting pad pressures, knock-out, and part ejection to improve consistency.

• Surface Defects: Polishing die surfaces and adjusting material flow to eliminate scratches and surface marks.

Tryout Capabilities

Our tryout facility includes:

• Mechanical and hydraulic tryout presses in various tonnage ranges

• Material testing equipment including tensile testing and hardness testing

• CMM (Coordinate Measuring Machine) for dimensional inspection

• Surface inspection equipment for visual and optical quality checks

• Experienced die makers and process engineers

Haoxinran provides tryout services for dies we manufacture as well as customer-owned dies that need debugging or optimization. Contact us to discuss your die tryout requirements.
