Have you ever wanted to create the look of a different material on a plastic part? Plastic parts not only benefit from designs that are pleasing to the eye, but they also benefit from the way a part feels when handled. Depending on the application, you may want your part to be as smooth as glass or possess a rough feel to indicate strength and durability. One way to injection mold a part with a unique look and/or feel is through the use of mold texturing.

What is Texturing?

Texturing is a process used to apply patterns to a mold surface. This process allows flexibility in creating the final appearance of your parts. Texturing is an integral piece in overall product development and should be considered during the design process to achieve the desired results. Texture can be a functional component of design as well. Imperfect parts can be camouflaged by the right texture. Is the part designed for frequent handling? Texture can be used to hide finger prints and improve the grip for the end user. Texture can also be used to reduce part wear from friction.

What Textures Are Available?

Quickparts has the ability to produce a wide variety of textures such as:

•  Natural/Exotic

•  Matte Finishes

•  Multi-Gloss Patterns

•  Fusions

•  Graphics

•  Leather Grains/Hides

•  Woodgrain, Slate, & Cobblestone

•  Geometric & Linens

•  Images or Logos Incorporated into the Pattern   

How Do I Design for Texture?

When applying a texture to your part, you need to adjust your CAD drawing to accommodate for this surface variance. If you are designing for texture on a surface that is perpendicular or angled away from the mold opening then no draft changes are necessary. If your texture is on a parallel surface with the mold opening, however, increased draft is necessary to prevent scraping and drag marks that could occur during part ejection.

Rule of Thumb:

Different textures have different impacts on the molded part. The rule of thumb when designing for texture is to have 1.5 degrees of draft for each 0.001” of texture finish depth.
