Metals: Stainless steel, copper, aluminum, zinc alloys, titanium alloys
Decorative elements: Kevlar, Carbon fiber, leather, textile If required, special materials can be provided, or we can advise you on the required properties.
What is the solutions for transparent Prototype (PC/PMMA)?
PC: will be polished by steam polishing, surface roughness (Ra 0.06~Ra 1.0 )can be achieved. The PC block are available in a thickness of 150 mm. the milling radius for facets and reflector surfaces)——Standard: R 0.15 mm, Minimum: R 0.1 mm (depending on the component)
PMMA: polished by hand, surface roughness can achieve Ra 0.04~Ra 0.08, the maximum raw part thickness (PMMA Clear, maximum 190 mm, PMMA lilky, 80 mm, PMMA Black , 60 mm), PMMA color are available like Transparent, black, white, Milky (diffuse) for CNC machining
Which colors can be reproduced in vacuum casting? Can you display VDI 3400 surfaces?
With PU casting, Any colors can be displayed, e.g. blue, red and also diffuse colors. clear transparent (ABS/ PC/ PMMA)
With CNC machining, we can create VDI surfaces after high-gloss polishing by painting.
With injection molding tools, the structures are already incorporated into the molds.
