What is Mold texturing?

Mold texturing is a key process in the manufacturing of plastic injection molded parts, allowing specific surface finishes to be applied directly to the mold cavity. This treatment serves both aesthetic and functional purposes, as it directly impacts the appearance, feel, grip, and optical behavior of the final product. The texture is transferred to the part during the injection cycle, eliminating the need for additional post-processing.

There are several techniques used for mold texturing, including chemical etching, laser engraving, and photochemical machining. Each method offers different levels of detail, precision, and repeatability. Chemical etching is widely used due to its ability to create complex patterns cost-effectively. Laser texturing, on the other hand, allows for high-definition and personalized designs, making it ideal for short production runs or unique design requirements.

One of the most common reasons to apply mold texturing is to enhance the visual appeal of the product. Through this process, materials like leather, wood, brushed metal, or geometric patterns can be replicated, adding perceived value to the component. In industries such as automotive, consumer electronics, and packaging, surface finish is a decisive factor in product acceptance by end users.

Beyond visual aesthetics, texturing can also improve the functionality of the molded plastic. For example, in technical or industrial applications, a rougher surface can increase friction and improve grip. In products that come into frequent contact with hands, mold texturing helps hide fingerprints, scratches, or wear, extending the life of the component. It can also affect how light interacts with the surface, reducing unwanted glare or improving color uniformity.

Another important aspect is that mold texturing can contribute to the demolding process. Depending on the type of plastic and part design, certain textures can facilitate the ejection of the part from the mold, reducing defects and improving the efficiency of the injection cycle. This results in fewer stoppages, greater production stability, and a lower rejection rate due to surface issues.

At Plásticos Lezo, we understand the importance of surface finish in plastic parts and work closely with our clients to define the most suitable level of texture based on the final use of the product. Our technical team provides guidance from the design phase, evaluating the material type, part geometry, and injection process to ensure that the texturing is applied effectively and meets both functional and aesthetic requirements.

We work with a network of specialized partners in mold texturing, capable of producing everything from standard patterns to fully customized textures. This enables us to offer our clients full control over the final finish of their parts, strengthening their brand identity and market differentiation.

Mold texturing is not just an aesthetic detail; it’s an engineering tool that enhances the performance, perception, and durability of plastic parts. When applied strategically, it can make the difference between a standard product and one that truly stands out in design and functionality. That’s why more and more companies are integrating textures into their parts as a core part of their product development strategy.
