Mold texture — slate / stone analog

texture · textured · MT slate, MT-11035 stone analog, slate mold texture

A mold-side photo-etched texture that mimics fractured slate or geological stone — irregular ridges and valleys with a distinct directional component. The molded plastic part reads as cast-stone or quarried surface, even on injection-molded ABS. Used on high-end consumer-electronics enclosures wanting a heavier hand than the MT leather-grain texture.

Photochemical etch in the slate / stone family — Mold-Tech MT-11035 stone (Ra ~12 µm, slight directional grain), VDI 3400 reference plates 38–40 with directional masking. Distinguishes from MT pebble (regular pattern) and MT sand (irregular fractal) by having distinct directional ridges. Release with ~5° draft per side. Pairs with darker matte resin formulations to read 'cast stone'; pairs with metallic-flake resins to read 'cast metal.' Common spec on premium consumer-electronics housings, audio-equipment cases, modern-luxury small appliances.

character — directional stone-fracture texture, evokes quarried surface, premium-consumer register.

Second life

reversibilityzero on the textured surface — texture is in the substrate. Removable only by additional material removal or by overcoating to fill the texture.
blocks substrate recyclingno
renewabilitymoderate — re-texturing is possible at the cost of removing the original texture and any material below it. Sandblast and acid-etch textures can be re-applied by repeating the original process.
