Features

Plastic and Rubber

In prototyping the combination of material and processing technique is one of the most complex choices. Executing a prototype almost always requires evaluations so that, for the technicians’ use and consumption, the average characteristics of the materials obtained by prototype construction are given. These can be used to get an idea of ​​technical and functional compliance.

PA= Polyamide (Nylon): ideal for aesthetically low stressed prototypes. It is an economical material that lends itself to aesthetic finishes (grouting and painting) for making maquettes.

PA+GF= Polyamide 30% glass fiber (Nylon-glass)
: ideal for medium-stressed semi-functional prototypes. It is a material that lends itself to the realization of complex and low thickness objects. Thanks to the optional impregnation treatment with epoxy resins it can be used successfully in the hydraulic field.

PA+AL= Polyamide 30% aluminum fiber (Nylon-Aluminum)
: ideal for semifunctional and functional stressed prototypes. It is a more expensive material than the previous ones but very powerful. It is characterized by a high breaking strength and excellent workability. It lends itself to the realization of complex and low thickness objects. Thanks to the optional impregnation treatment with epoxy resins it can be successfully used in the hydraulic field.

PA+C= Polyamide 30% carbon fiber (Nylon-carbon): ideal for highly stressed semi-functional and functional prototypes. It is one of the most performing materials, expressly formulated to meet the needs of the toughest areas such as the world of racing and extreme sports. It is characterized by a high breaking strength and an excellent elastic modulus. It lends itself to the realization of complex and low thickness objects. the details made of this material can be finished with processes that drastically improve the quality of the surfaces that can then be lacquered, providing a result of great value and usable in the wind tunnel.

Sintered rubber: ideal for semi-functional and functional prototypes requiring a high elastic response and deformation capacity. This material is ideal for making flexible parts such as joints, sleeves, diaphragms for airboxes etc. The part obtained from a granulated rubber matrix needs appropriate treatments to produce impermeable or fluid-tight objects.

These materials are non-standardized and do not correspond to similar industrial production materials. They have been formulated only to meet specific high-level needs, for which the aesthetic aspect is privileged rather than the specific mechanical and technical characteristics and can be generalized to:

High detail opaque resins: ideal for the production of models, masters for silicone molds and technical prototypes of small industrial objects (for example remote controls, microsystems, toys, casings and shells of small devices. there are off-white resins, black.

High detail semi-transparent resins: ideal for producing conceptual models. This type of detail can be worked with finishing processes in order to obtain high degrees of transparency for those prototypes that require perfect internal vision (lights, lenticular details or system casings whose interior is to be shown).

High definition elastomers with hardness 40-60-80 Sh (A) : ideal for producing prototypes of deformable objects, such as shoe soles, gaskets, sleeves and rubber-like diaphragms, mouthpieces, bellows, etc.

For the realization of particularly stressed parts and for extreme applications, polymeric Blends of specific formulation are used which guarantee superior performance and greater uniformity of response. These materials, although chemically identical to the previous ones, have a greater ability to bind and blend together, providing mechanically superior characterizations of + 15%.
