How to Clean High-Gloss Injection Molds with Foamtec’s Sahara+ System

by | Mar 15, 2024


Injection molds play a pivotal role in the manufacturing industry, shaping countless plastic components we encounter daily. Achieving high-quality surface finishes on these molds is crucial, especially for industries that demand precision and aesthetics. Foamtec’s Sahara+ Cleaning System is a game-changer in maintaining injection molds with high-gloss SPI A1 and A2 surface finishes. In this blog, we’ll explore how this innovative system can transform the mold maintenance process and ensure the longevity of your molds.

Understanding High-Gloss SPI A1 and A2 Surface Finishes

Before delving into how the Sahara+ Cleaning System works its magic, it’s essential to understand the significance of SPI A1 and A2 surface finishes. The Society of the Plastics Industry (SPI) developed these standards to classify the quality of mold surface finishes:

  1. SPI A1: This is the highest quality finish, known for its exceptional gloss and mirror-like appearance. It’s commonly used in applications where aesthetics are critical, such as automotive interiors, consumer electronics, and medical devices.
  2. SPI A2: Slightly less polished than A1, SPI A2 surface finishes still offer a high-gloss appearance. These finishes suit applications where aesthetics remain important but can tolerate a slightly less pristine surface.

Maintaining such finishes can be challenging, as any imperfections or contaminants can degrade the quality of molded parts.

Foamtec’s Sahara+ Cleaning System: A Game-Changer for Mold Maintenance

The Sahara+ Cleaning System by Foamtec is a cutting-edge solution designed to address the specific cleaning needs of molds with high-gloss SPI A1 and A2 surface finishes. Here’s how it works:

  1. Scratch-free Cleaning: Unlike traditional cleaning methods that use wet or abrasive techniques, the Sahara polyurethane foam sponge scrubs do not scratch, ensuring that the gloss and finish are preserved.
  2. Durable and Conformable Foam Sponge: Sahara foam sponge is both durable and conformable, allowing intricate mold geometries to be cleaned more quickly and without the foam sponge shedding debris onto the mold. This feature is ideal for applying polishing compounds to mold cavities as it conforms to the geometric shape of the mold, affording faster cleaning.
  3. Streak-Free Finishes: MiraWIPE, the most widely used microfiber wiper, leaves a streak-free, mirror-like surface finish. Sahara+ and MiraWIPE are chemically compatible with all mold cleaners and IPA solutions.
  4. Cost-Effective and Sustainable: The Sahara+ Cleaning System enhances the quality of mold maintenance and offers cost savings. It reduces the need for harsh chemicals, abrasives, and manual labor, making it an environmentally friendly and economically viable solution.

Benefits of Sahara+ Cleaning System for High-Gloss Molds

Implementing Foamtec’s Sahara+ Cleaning System in your mold maintenance process brings a multitude of benefits:

  1. Preservation of Surface Finish: The system’s non-contact dry cleaning method ensures that the high-gloss SPI A1 and A2 surface finishes remain intact, maintaining the quality of your molded products.
  2. Increased Mold Longevity: By minimizing the wear and tear caused by traditional cleaning methods, the Sahara+ system extends the lifespan of your injection molds, reducing the need for frequent replacements.
  3. Reduced Downtime: A more efficient and less labor-intensive cleaning process can significantly reduce mold downtime, increasing overall productivity.
  4. Quality Assurance: Consistent mold cleanliness and surface finish quality lead to fewer defects and rejections, enhancing your product’s overall quality.


In industries where aesthetics and precision matter most, maintaining high-gloss SPI A1 and A2 surface finishes on injection molds is paramount. Foamtec’s Sahara+ Cleaning System revolutionizes mold maintenance, offering a sustainable, cost-effective, and highly efficient solution. By preserving surface finishes and extending mold longevity, this innovative technology ensures that your molds consistently deliver top-quality products, meeting the demands of even the most discerning industries.
