VDI / SPI sample card made of ABS plastic
Order our free sample cards with construction guide

Want to select the right surface texture or roughness for your plastic component? Our new sample card set will help you make the right choice.
Request our free set with two sample cards made of ABS - In White and black – and also receive our Design guide for plastic molded parts as a print edition.
surface structures and surface roughness
The sample cards illustrate the actual visual and tactile effect of various surface textures on ABS plastic. They are a practical tool for the targeted evaluation of material and design, even in the early stages of product development.
By directly comparing SPI surface treatments and VDI 3400 textures, you gain a reliable basis for selecting the optimal structure for your application. At the same time, the cards facilitate communication with designers and suppliers – quickly, clearly, and efficiently.
The set allows for direct comparison of the following surface types:
- 12 SPI surface treatments, classified from A1 to D3, covering a spectrum from highly polished to heavily textured, rough surfaces.
- 12 common VDI 3400 surface textures, ranging from VDI 12 to VDI 45, which offer different degrees of roughness for different applications.
The combination of both color variants (white and black) offers you a precise assessment regarding light behavior, contrast effect and texture effect – a crucial advantage for applications in medical technology, laboratory technology and cleanroom environments.


Design guide for plastic molded parts
In addition to the sample card, our technical plastics guide This guide contains:
- Technical notes and best practices for the development and production of plastic parts
- Detailed information on design requirements and design optimization
- Instructions for selecting suitable materials and procedures
Simply fill out our order form, and we will send you your personal sample card including construction guide quickly, free of charge and without complications.
The guide is also available as a PDF download.
