ISO 9001 Certified Aluminum Honeycomb Energy Absorber with Custom Pre Cut Dimensions and Expanded Cell Size for 4 Pin Support Fitment in Crash Dummies

ISO 9001 Certified Aluminum Honeycomb Energy Absorber with Custom Pre Cut Dimensions and Expanded Cell Size for 4 Pin Support Fitment in Crash Dummies

Anthropomorphic Test Devices (ATDs) — commonly known as crash test dummies — are used worldwide for the evaluation of automotive safety restraint systems in crash testing. These regulated test devices, governed by the Hybrid III specifications in the U.S. Code of Federal Regulations (Part 572, Subpart E) and European ECE Regulations, require rigorous certification procedures to ensure consistent and repeatable performance.

Our ISO 9001 Certified Aluminum Honeycomb Energy Absorber is specifically engineered to create the precise deceleration pulse required for ATD neck flexion-extension certification tests. Each block is tested and internally certified to ensure consistent and repeatable testing results.

4-Pin Support Fitment Design

A key differentiator of this energy absorber is its under-expanded cell size option — available upon request at approximately 11/16″ — which is specifically calibrated to better fit 4-Pin supports used in ATD mounting fixtures. This design feature ensures:

· Secure engagement with standard 4-pin support structures
· Precise alignment during neck flexion-extension test setups
· Reliable pulse generation without unwanted movement or shifting

---

Custom Pre-Cut Dimensions

Recognizing that each testing protocol and dummy configuration presents unique requirements, our energy absorbers are supplied as:

· Slices — uniform thickness sections for standardized testing
· Strips — narrow-width formats for specific fixture configurations
· Pre-cut blocks — custom dimensions according to customer needs

This flexibility allows laboratories and testing facilities to order exactly what they need, eliminating material waste and ensuring that the absorber fits seamlessly into existing test fixtures.

Application Context

Neck Flexion-Extension Testing — ATD certification requires neck extension/flexion tests to ensure certified performance of the dummy. Our aluminum honeycomb energy absorbers are the industry-standard solution for creating the controlled impact pulse that validates dummy neck response characteristics.

Beyond automotive safety, ATDs are also utilized in wheelchair testing, medical equipment evaluation, and sports equipment safety assessments — making our energy absorbers versatile components across the broader safety testing ecosystem.

Specifications:

Pasia Honeycomb Energy Absorbers can be supplied based on the cell size, foil thickness and layer, aluminum grade, width and length etc. The shape and parts can be also customized as per the request from client. The crush strength can be achieved on the performance of the foil thickness and special structure.
