Interlaken Draw Bead Simulator (DBS) System
Interlaken Draw Bend Simulator (DBS) Suppliers in India
The Interlaken Draw Bead Simulator (DBS) System from Interlaken Technology Corporation is a specialized laboratory machine designed to accurately simulate real press draw bead conditions. It is used to evaluate material restraining force, friction behavior, lubrication efficiency, and sheet metal formability under controlled, repeatable conditions.
This system is widely adopted by automotive OEMs, steel manufacturers, and R&D labs for die development, material comparison, and process optimization before full-scale stamping

The Draw Bead Simulator replicates the mechanical action of draw beads used in stamping dies. By pulling a metal strip through interchangeable bead geometries under controlled force, the DBS measures restraining force, pulling force, and material flow behavior. This allows engineers to predict forming performance, reduce die tryout time, and prevent costly production defects.
Pull force capacity: 50–200 kN (model dependent).
Test speed range: 0.1 to 500 mm/min.
Bead geometry: Round, square, trapezoidal (custom optional).
Specimen width: 20–100 mm (customizable).
Control type: Servo electric or hydraulic.
Data output: Force vs displacement, restraining force coefficient.
Software: PC-based data acquisition and reporting.
Applications
Automotive sheet metal forming analysis.
Evaluation of lubricants and surface coatings.
Comparison of steel, aluminum, and advanced high-strength steels (AHSS).
Die design validation and optimization.
Research in tribology and metal forming.
Failure prevention such as tearing, wrinkling, and excessive thinning.
Benefits
Predicts real stamping behavior before die manufacturing.
Reduces costly tool rework and production downtime.
Optimizes blank holding force and lubrication selection.
Improves part quality and dimensional stability.
Accelerates new material qualification.
