Overcoming Complex Mold Texturing Challenges

  1. Overcoming Complex Mold Texturing Challenges

    Leave a Comment

    The mold manufacturing industry is constantly evolving. As a result, options for overcoming complex mold texturing challenges are evolving, too. 

    Our complex marketplace demands new and innovative design possibilities with higher accuracy and tighter tolerances while keeping production times as short as possible. For example, some projects may require depth or detail unachievable by acid etching, while others demand consistent results with high-volume multi-cavity tools. 

    Laser texturing might be the right solution to overcome these complex challenges. Here are a few key advantages to consider. 


    Overcoming texturing challenges by applying laser texture directly over a EMD mold cavity, no polishing required.

    Amerimold 2021 Tech Talk – “Where Mold Manufacturing Connects”

    St. Paul Engraving is excited to announce we will be speaking in the Amerimold 2021 Tech Talk program Wednesday, September 22 at 2PM detailing how five-axis laser texturing can save time and reduce costs. This presentation will review the advantages and limitations of laser texturing as well as critical mold design considerations. For example, in most cases you can laser texture over EDM and weld, saving time and cost on polishing and tempering, when applicable you can leave molds partially assembled, and texture pins and inserts in place.

    We are excited to participate in such an impactful way!

    Mold Repair

    St. Paul Engraving’s proprietary repair process can prolong the life of your company’s mold. Through our laser repair process we can directly repair a damaged area and blend into existing texture eliminating any visual defects to restore your tool to a like-new condition.

    Important to note: if you find a textured area or parting line that is damaged on your mold, contact us before any welding or polishing is done. In many cases we can hand work the steel back and repair without any weld. If welding or polishing is required we prefer to do this in house as there are several factors to consider.

    If welding is required, follow the below tips for optimal chemical repair:

    • Weld with the same material the mold was made from; i.e P-20, S-7, H-13 or stainless steel. If the same material is not used, the weld may etch at a different rate leaving a white line around the weld when repairing the texture.
    • Mold must be properly heated prior to welding. If not properly heated, it can cause the weld to cool too quickly. If this happens, even when using the same material, it will cause the weld to etch at different rate which would then require stress tempering to normalize the steel to get a constant etch for the best repair result.

    With the advances of the laser texturing industry we have developed a laser repair process at St. Paul Engraving that can be used on any mold whether it was laser textured or chemically etched to repair these damaged areas. Through this process we can laser repair the area and blend into the existing texture eliminating any visual defects restoring you tool to a like-new condition.
