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.
Laser Texturing Benefits
Laser texturing is a fully digital process that replicates all industry-standard patterns and allows for virtually limitless design possibilities. Laser texturing does not undercut detail, which is problematic with acid etching that moves outward as it etches downward. The key to laser texturing is the 0.002-inch beam width that unlocks the potential to achieve depths and details not possible through acid etching, and permits the design of innovative, complex patterns to meet the rapidly changing needs of the medical, aerospace, automotive, defense and consumer goods industries.
A good rule of thumb is: If the EDM finish is lighter than the texture you are applying, you can laser texture over the EDM finish.
As a fully digital process, laser texturing delivers highly repeatable precision results, which is not only ideal for maintaining consistency throughout projects but allows the operator the ability to pick back up on molds for repair or to refurbish the texture on high-volume tools that may wear over time.
Also, in most cases, you do not need to remove the EDM layer to laser texture a mold. Avoiding this step reduces the time and cost associated with polishing, which also helps to maintain tight tolerances. However, the surface finish requirements of the texture dictate the need for polishing.
A good rule of thumb is: If the EDM finish is lighter than the texture you are applying, you can laser texture over the EDM finish.
When machining a mold, mistakes and cutter breakage can occur, resulting in weld that is often undetectable until you apply a texture. Chemical etching can bring out weld areas and yield an uneven texture.
Laser texturing, on the other hand, is not as susceptible to weld and hardness issues. In most cases, it is completely unaffected. Laser texturing produces consistent results regardless of the mold’s condition.
Laser Repair Benefits
Taking a mold out of production for a texture repair or revision is never ideal because lead time is critical. However, laser repair is not only the fastest solution, but offers the greatest results. The process offers several key advantages when you damage a mold texture that was either laser textured or chemically etched.
When welding is necessary there are several variables to consider, including steel type and size of the weld area. Be aware of hardness issues that may arise when welding. For example, a block that draws heat away from the weld too quickly produces an uneven hardness and allows acid etching to reveal rings. Tempering the block can fix this issue, but it is a time-consuming process that does not guarantee success.
When laser repairing, you can texture over the weld and blend into the existing texture—whether initially chemically etched or laser textured—without any issues.
Using laser technology for your next texture project or repair will avoid costly delays due to EDM or weld.
When it comes to manufacturing, the surface texture is the 3-dimensional topography of a given solid. It is impossible to get a perfectly featureless or flat surface topography. Therefore, there is some kind of texture on every surface.
You can see some of these textures as regular repeating patterns. Some of them can be rather random and a lot difficult to describe generally. Generally, texturing involves the creation of an array of patterns on the surface of products.
Mold design and texture give unique features and look to plastic molded parts. The designer chooses texture due to the extensive functionality that it provides. Some of the primary purposes of mold texture are as following:
It gives a pleasant look and aesthetic feel to the product. Plastic mold texture improves the appearance and gives flexibility to the products. The mold texturing process makes it possible to conceal the imperfections of parts. Such as welding lines, shrinkage, shadow marks, and slider steps. It provides a surface finish that can offer strong resistance from any damage. We can end plastic flow creases with the thickness of the texture. It also gives non-slippery features and strength to the molded parts. Paint adhesive is excellent during the molding operations. Texture makes part easy to hold.
We can improve product durability and surface strength with an injection mold. They give a non-plastic appearance, and it’s a cost-effective procedure.The texturing process enables us to make intricate designs and patterns on parts.
If you select mold texturing companies, it’ll help to gain the desired surface finish. You must know about the material, tooling, and other factors. If you need more information about surface finishing. Contact us for the best results and design for your plastic part.
Most plastic parts need additional processing before completion. Many of these processes work towards improving the appearance and aesthetics of the product. One of those processes is the inclusion of mold surface textures.
Surface finish is a critical factor when it comes to the appearance of your product. It also influences the performance of the product. Therefore, you can say that it serves both a functional and aesthetic purpose. You must understand that your choice of mold texture is a crucial factor. It determines the look, feel, and performance of your product.
