Manufacturing method of a body protection and resulting body protection, wherein the method comprises producing a structural shell (10) with a maximum thickness of 5 mm, made of thermoplastic material, and defining a concave interior (11) and a convex exterior (12); over-moulding an expanded polystyrene layer (20) overlapping the concave interior (11) of the structural shell (10), producing its adhesion by close contact to the structural shell (10); and wherein the structural shell (10) is produced by means of the distributed placement, in a mould, of a mixture of thermoplastic material and of reinforcing fibres stable at temperatures equal to or lower than the melting temperature of the thermoplastic material, the closure and heating of the mould causing the melting of the thermoplastic material without damaging the reinforcing fibres, and the subsequent cooling of the mould, hardening the thermoplastic material with the reinforcing fibres embedded therein.

A method for manufacturing a microfluidic device can include providing a base component to define a first portion of the microfluidic device. A cap component of the microfluidic device can be fabricated with a sealing lip extending a first distance from a first side of the cap component and a support portion extending a second distance, less than the first distance, from the first side of the cap component. The method can include positioning the cap component and the base component within a mold to bring the sealing lip of the cap component in contact with the base component. The base component, the support portion of the cap component, and the sealing lip of the cap component together can define a cavity. The method can include injecting a polymer material into the mold to cause the polymer material to fill the cavity.
