From CNC milling and turning to grinding. From prototypes to low-volume production. we have the right CNC machining proposal to produce metal and plastic part tight tolerance, high quality with excellent finish.
From prototype to low-volume production, Polyurethane vacuum casting provides end-use, rigid or flexible plastic parts with production-level quality from inexpensive silicone molds. Copies made in this way show great surface detail and fidelity to the original pattern.
As one of the 3D printing process, SLA can produce highly detailed plastic parts with intricate geometries and excellent surface finishes as compared to other additive processes. Cost is competitive and the technology is available from several sources.
Metal sheet is a metal rolled thin and flat in the form of a sheet. It can be cut and twisted into a variety of shapes. Sheet metal is available in flat pieces or coiled strips. There are many different metals that can be made into sheet metal, such as aluminium, brass, copper, stainless steel, etc..
