The present invention relates to a method of manufacturing a strap including, providing a mould for a strap, the strap comprising a first opening, inserting a first component into said mould, arresting said first component with respect to said mould, such that said first component is proximate said first opening, injecting said mould with a wet applied structural component, wherein said first component comprises a first keying feature which increases the surface area of the first component.

Methods, systems, and apparatuses for retaining magnetic properties of magnetic elements while undergoing manufacturing processes are presented. In one embodiment, a manufacturing fixture includes a temperature controlled region suitable for retaining a magnetic element. The manufacturing fixture also includes a cooling mechanism configured to maintain the magnetic element at an acceptable temperature range during a thermally active manufacturing process. The temperature controlled or stabilized region can include a structure configured to receive the magnetic element and a sensor, or sensors. In one embodiment, the sensor can be configured to measure an ambient temperature of the temperature stabilized region. In another embodiment, the sensor can be a magnetic sensor configured to determine a magnetic property of the magnetic element.
