Marcel Dias — Technical Editor

Marcel Dias, Technical Editor at MoldTexturingGuide

Marcel Dias is a mold texturing and surface finishing specialist with over 28 years of hands-on experience in the plastics tooling industry. His work covers the core texturing processes used in the field, chemical etching, laser texturing, and EDM texturing, and the specification systems that govern them, including VDI 3400, SPI surface finishes, and Mold-Tech texture standards.

Through decades of practical work with tooling and molding operations, Marcel has direct experience in how texture specifications are selected, converted between standards, applied to different polymers, and troubleshot in real production, from draft-angle decisions to weld-line and gloss issues on the shop floor.

Areas of expertise

  • Mold texturing processes: chemical etching, laser texturing, EDM texturing
  • Specification standards: VDI 3400, SPI surface finish, Mold-Tech textures
  • Standard conversion and surface roughness (Ra/Rz) interpretation
  • Draft-angle specification by texture grade and polymer (ABS, PP, PC, PA)
  • Texture defect diagnosis and correction
  • Functional and micro/nano texturing applications

Professional background

Marcel is the founder of M1 Textura, a Brazilian mold texturing company based in Santo Andre, Sao Paulo, specializing in on-site texture repair, new texture development, and surface engineering consulting. Over his career he has worked on automotive-sector projects across seven countries, Germany, France, Portugal, Italy, Argentina, the United States, and China. This cross-market exposure informs his understanding of how texture standards are applied and reconciled across different regional practices.

His work and the founding of M1 Textura were featured in the Brazilian trade magazine Plastico Industrial (Aranda Editora), which reported on his 28 years of experience and his mobile mold-texture repair approach. Read the feature here.
