Texture finishes are normally achieved through acid or laser etching.
Tool texture, or texturing, is subcontracted to third party sources like Mold-Tech, one of the best known suppliers in the industry. Mold-Tech have facilities in Portugal, and is frequently used by Molco.
Tool texturing is a process that normally requires careful masking of areas not to be textured, with an awareness and management of drafts that vary greatly depending on the type of texture that is chosen.
Much care should be taken in the early review of projects, following suggested specified minimum draft requirements . A common rule used in the industry, for a texture draft requirement, is 1º of draft per each .0005” to .0006” (0,012mm to 0,015mm) of depth of the specific texture being considered.
Texture minimum draft requirements can result in changes to part designs and assemblies and can radically impact tool design development.
“Textured” finishes, with a far lesser range and control, can also be achieved through processes like dry-blasting procedures (sand, glass bead or other), through EDM (electro discharge) or other processes.
