Rapid prototyping

From project, by prototype, to production

Seat Plastic realizes prototypes using mainly two processes, stereo lithography (SLA) and selective laser sintering (SLS), both quick procedures to get indispensable elements to define details, make modifications and simplify the sealing test.
Short lead times, no dimensional limit and high quality level are the main prerogatives.
Prior to realising the mould and based on a prototype analysis, all potential failures are evaluated and shared with the customer in order to propose appropriate technical solutions.

Selective Laser Sintering (SLS):

SLS is a technique that uses a laser as the power source to sinter powdered material to create a solid structure. The laser fuses small particles of powder into a mass that has a desired three-dimensional shape. It selectively fuses powdered materials by scanning cross-sections generated from a 3-D digital description of the part: after each cross-section is scanned, the powder bed is lowered by one-layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.
In contrast with some other additive manufacturing processes which most often require special support structures to fabricate overhanging designs, SLS does not need a separate feeder for support material because the part being constructed is surrounded by unsintered powder at all times.

Stereolithography (SLA):

SLA is an additive manufacturing process that works by focusing an ultraviolet (UV) laser on to a vat of photopolymer resin. With the help of a computer design software, the UV laser is used to draw a pre-programmed design or shape on to the surface of the photopolymer vat. Because photopolymers are photosensitive under ultraviolet light, the resin is solidified and forms a single layer of the desired 3D object. This process is repeated for each layer of the design until the 3D object is complete.

Vacuum Casting:

Silicon Molding is also available to deliver economic benefits for small batches of parts.
Starting from a model obtained through CNC machining, SLA, SLS, or others (or provided by the Customer), we are able to duplicate a small series of parts in polyurethanes or other polymers by vacuum casting in silicon moulds: parts made via this technology reflects most common plastic materials (ABS, PP, PC, PP) and can be used as initial production parts.
Vacuum Casting/Silicon Molding is one of the best way for low volume manufacture of plastic Parts: by using silicon mould to instead steel mould, the cost will be reduced. Usually one silicone mold can cast about 20 to 25 pieces of parts by using silicon mould instead steel mould, depends on complexity, painting or original color, size and other factors in different parts.
