That depends on the selected finish:
- 0.00 mm dimensional change (100 % true to size): Our standard bead-blasting (shot peening), deep-black immersion dyeing (dye penetrates into the pores rather than building up a layer), and chemical vapor smoothing do not alter part dimensions by a single micron.
- Minimal material removal (-0.05 to -0.20 mm): Mechanical sanding & vibratory tumbling gently radius sharp edges.
- Minimal coating build-up (+0.05 to +0.15 mm): 1K or 2K PU spray painting applies a protective coating layer (allow approx. 0.2 mm extra clearance on tight mating features).
Deep-black immersion dyeing is ideal for powder-printed functional parts, moving joints, and intricate geometries because there is no paint layer to chip and all tolerances remain 100 % unchanged. Good to know: Because the dye bath is hot, very thin walls under 1.5 to 2.0 mm may warp slightly from the heat. For thin-walled components or custom RAL colors, we recommend our cold-applied 1K or 2K PU industrial coating.
Our 1K spray coating (matched to RAL) is the fast, economical choice for design models, trade show exhibits, and indoor covers. For our 2K PU coating (two-component polyurethane), base coat and hardener are mixed immediately prior to application. This creates a chemically cross-linked, automotive-grade protective finish—extremely scratch-resistant, impact-tough, and resistant to UV light, weather, chemicals, and cleaning agents (available from dead-flat matte to satin and high gloss).
Yes! Every part we manufacture in our powder bed processes (PA12, PA11, TPU) is surface-densified with fine polymer beads as standard and at no extra cost after depowdering. This closes surface pores with zero material removal and transforms the grainy raw surface into a silky-matte, dirt-repellent finish.
Yes. Upon request, we deliver ready-to-install assemblies: from heat-setting brass threaded inserts (M2 to M12) and direct thread tapping (including imperial sizes) to structural bonding, sealing, and integrating gaskets, off-the-shelf hardware, and electronic components.
