HEADFORMS

Our entire production process takes place in-house. We have our own engineers, programmers, designers as well as CNC machines and operators. These in house resources allow us to be extremely competitive and flexible, whether it is a rush order or a custom design, Cadex gets the job done.

Consistency Reliability Durability

CNC (Computer Numerical Controlled) machines are used throughout our production process.

Advantages : Very high precision accuracy on the dimension of each surface inside and outside the head forms. Machining the head form provides identical results from one order to the next. All Planes (i.e. references plane, basic plane, transversal plane and longitudinal plane) are machined into the head form to provide technical support to the user.

Magnesium K1A has been selected by the standards organization because the material provides the best energy transfer throughout the head form. Aluminum or steel would either absorb or amplify the energy of an impact which would modify the results during acquisition tests. Magnesium K1A is composed of 100% pure Magnesium with an additive of 0.3% to 0.7% of Zirconium.

Head forms are mainly used in impact testing, so over time they become damaged (see figure below) during different test and especially during the research period. Attempts to make the smallest, thinnest, lightest, well ventilated helmet takes its toll on a head form. It is very important to look for any visible signs of damage to a head form. The result of am impact test on a damaged head form may PASS when in reality is should have FAILED. At Cadex, we have a program to refurbish the outer surface of head forms as well as reconstruct the plane line that may have been lost in the testing process. The head forms get a complete overhall, including a paint job, making them look as good as new. Note For Half Head Forms: (Fig. 2) It is very important to maintain the bolt attachments inside the head form. These bolts keep the assembly in the correct position, avoiding any potential vibration that may provide noise in your signal impact acquisition. Only use 5/16NC18 - 1 3/4 bolts to avoid any damage to the thread. If the area around the screws gets damaged we, can specifically target these areas in our repairing & recycling program.
