Front Bumper Beam Attribute checking fixture – Precision Inspection Solution

Application

Our Attribute checking fixture is designed for the precise dimensional inspection and quality control of automotive front bumper beams. This Attribute checking fixture ensures accurate validation of critical features such as mounting hole positions, contour profiles, weld nut alignment, and assembly interfaces. It is widely used in automotive manufacturing for stamped parts, welded assemblies, and final production validation.

Material Selection

Framework:

High-strength carbon steel (Q235B) for superior rigidity and long-term stability.

Locating & Checking Components:

Heat-treated tool steel (Cr12MoV) for exceptional wear resistance and durability.
