TECHNICAL ASSISTANCE

One of the most valuable services provided to you by the Mold-Tech organization is ourtechnical assistance. Members of the Mold-Tech Sales and Engineering team receivecontinuing education on the latest output from our Research and Design group to provide you with the most effective solutions for your product. Were available to help you. 

GRAPHIC ARTWORK / TEXTURE PATTERN DEVELOPMENT DESIGN STUDIO

Every Mold-Tech facility throughout the world has the capacity to create new artwork or modify andrefine existing graphic artwork and texture patterns to meet your requirements.Mold-Techs Design Studio has a team of technicians that are dedicated specifically to developing newcustomized textures.  With the most advanced 3-D digital scanning technology,digital imaging systemto replicate and manipulate textures, and rendering capability, we can quickly give you textures thatwill Bring Your Plastic to LIFE!  Ideas are endless.

RENDER-TECH SEAMLESS TEXTURING®is Mold-Techs exclusive advanced technology that givesthe ability to digitally wrap a digital part surface file with any texture for design review.The texture canbe orientated to suit exacting specifications, including complex contours, and then laid into the moldsurface seamlessly.  This technology is especially valuable for geometric or graphic texture patterns.

TEXTURE DEPTH AND SIDEWALLDRAFT CONSIDERATIONS

Toassure clean ejection of your part, we suggest using a simple rule for determining draft:


 

This rule is for sidewalls of the tool that the part will shrink away from.  Areas inthe tool that the part will shrink toward will require more draft.  Lifters, slides,cams, and other tooling components should have their texturing draftrequirements evaluated based on their action as they move away from the part.Shut-off conditions on textured sidewalls may also be affected by the texturedepth / tool draft relationship.

Texture depth can be reduced in specific areas and/or the texture pattern can be softenedon surfaceswhere there are ejection concerns.  Part design, part size, molding materials, texture construction, and other molding factors have asignificant impact on ejection issues.  Mold-Tech has the largest staffof technical advisors in the industry.We are available for early involvement in your project to assure that your decorating ideas are realizedon your product.

WHAT TOOLING MATERIALS CAN BE TEXTURED?

o assure that your molds are successfully textured, Mold-Tech has formulated the largest selection of moldetchants in the industry.Standard tool materials such as P-20, H-13, S-7, 01, A1, A2, A6, 420 stainless,beryllium copper, kirksite, forged, wrought and cast aluminums have all been textured successfully.Since your tooling material choices can significantly affect the texture appearance, Mold-Techs TechnicalAdvisors are always available to discuss and test your specific material preferences.

WHAT FINISH IS REQUIRED ON THE MOLD SURFACE FOR TEXTURING?

To assure that your texture pattern shows clean and without any surface flaws, we recommend thefollowing surface finishes:• 400 paper (SPI B-2) for textures less than .001 deep.• 400 stone (SPI C-2) for textures between .001 and .003 deep.• 320 stone (SPI C-3) for textures over .003 deep.

HOW DO I SPECIFYGLOSS?

Gloss on a part is typically measured with a 60 degree gloss meter. The gloss number represents thepercentage of light that is reflected off of the part. The gloss on a part is the result of many factorscoming together: molding material, tool temperature, material temperature, venting, cycle time, wallstock thickness, texture patterns, mold coatings, etc.Mold-Tech uses a variety of blast media to help set the final gloss on the mold surface.  Each part hasits own factors to consider C contact us to discuss specific needs, factors and expectations. With many gloss targets being pushed lower, Mold-Tech has developed a laser-generated micro overlaytexture called MicroMatte C lowering gloss and giving a rich and realistic appearance to textures.

WHAT ABOUT WELDING ON ASURFACE THAT WILLBE TEXTURED?

If you are considering welding on a surface that is to be textured, proper welding procedures willgreatly increase the final outcome of the texture appearance.• The mold should be pre-heated prior to welding, welded while the mold is hot, and annealed afterwelding. Contact the steel supplier for proper welding procedures and weld rod material.Any difference in hardness, composition or texture structure in the welded area when compared to theparent metal tends to produce an irregularity in the texture appearance after etching. When properwelding procedures are followed, differences can be minimized and welds become easier to blend-inand repair to a very acceptable level.If you are unsure of the direction to proceed with welding, Mold-Tech can help C with decades ofexperience to draw from as well as relationships with the steel manufacturers and welders, we canhelp give you the latest information you need to achieve the best results.  

HOW DO I PREPARE MYMOLD FOR TEXTURING?

1. Completely dis-assemble mold C only send components to be textured.

2. Make sure that all seal-off (shut-off) areas are properly scribed.

3. Remove all EDM scale from areas to be textured.

4. To avoid shipping damage, please take care in packaging your shipment.
