Texturing

The guidelines for a successful texture are very basic. All textured surfaces should have a 320-400 SPE-SPI finish and be free of EDM, recast, tool marks, and polishing tears.

For proper part release, molds must be constructed with adequate draft angles. The standard rule of thumb is a minimum of 1½ degrees of draft for each thousandth of texture depth. (Example: For a 0.002-inch deep texture, 3 degrees minimum draft is required.)

Keep in mind that mold construction, part and sidewall thickness, material shrinkage, pattern type, and direction of pull are all factors that must be considered in order to develop the appropriate draft angle.

For best results, contact us at (303) 684-9000 in the design stages of your project. We'd be glad to answer any of your questions.


Texture Repair

Repairing a texture does not always require weldment.  Moderate polishing or pushing metal may be your answer. 

Welding a tool causes differences in the hardness, composition, or grain structure in the area welded. This may cause the metal to etch at a different rate, resulting in a variation in the appearance of the texture when compared to the parent metal.

To receive the best possible results, we recommend these guidelines when welding areas that require a textured finish.

Call Western Texturing at (303) 684-9000 for recommendations specific to each tool.

Whenever possible, avoid welding an aluminum cavity surface. For best results, press fit aluminum tools with like aluminum, turned round. Round bar stock has a different grain structure and will give the texture a less satisfactory appearance.

Preheat steel molds to a temperature prescribed for your steel type before welding. Use a welding rod of the same metallurgical composition as the parent metal. Reheat the mold after welding. Temperatures vary relative to different mold materials. Contact material suppliers and/or your local heat treater for recommended temperatures.

Feel free to give us a call at (303) 684-9000 to answer any questions you may have about a project you are currently working on. We always have time to discuss the texturing process or the appropriate steps necessary to ensure a successful texture or texture repair.
