Gas Buildup Issues

Gas Buildup in Injection Molding

Gas buildup can lead to burning, splay, and other defects on molded parts.乐动体育官方网址Nanoplas products can help keep your output defect-free and your run time up.

常見原因:

Over Applying Mold Release

Over applying mold release to avoid sticking during a full production run can cause the mold release to build up and clog the vents.

Solution:

Dri-Kote™

Quick dryingDri-Kote mold release sprayis a dry mold release, which has the advantage of being difficult to over apply.This helps prevent mold release buildup, especially in the problem areas of a mold, which in turn mitigates gas build up.Dri-Kote works for most injection molding needs.

Solution:

Tuff-Kote™

Made for difficult-to-release parts, Tuff-Kote mold release spray provides a longer lasting release.Also a dry mold release, it minimizes the potential for build up and residue to reduce the risk of gas build up.

Solution:

&#20048;&#21160;&#20307;&#32946;&#23448;&#26041;&#32593;&#22336;A Nanoplas Coating

Especially ideal for plastic or rubber part release,&#20048;&#21160;&#20307;&#32946;&#23448;&#26041;&#32593;&#22336;Nanoplas coatingsuse nanotechnology to create a semi-permanent barrier on the mold's surface.They have no impact on finished part dimension, don't migrate to the part surface, and are non-toxic.Additionally, you apply them in-house and they cure in just a few hours.

常見原因:

Over Applying Rust Preventative

In some cases you may be dealing with rust preventative building up and clogging vents.It may be because your rust preventative is being over applied or is thick in nature.It could also be that your rust preventative is wet (as in not drying quickly enough), so it migrates throughout the mold.Applying a wet rust preventative to a hot mold will also create a tacky residue on mold surfaces.

Solution:

Mold Guard™

Mold Guardis a truly dry rust preventative, so it won't migrate or buildup when applied as directed.An adjustable fan tip gives better control over the volume dispensed.Plus, it can be molded through at start-up and creates little to no scrap.

Solution:

Mold Guard Green™

Mold Guard Greenprovides excellent film strength, and since it goes on dry it will not bleed into the mold or cause build-up.Tinted green, you can see where it's been applied so you're less likely to over apply.

常見原因:

Poor Venting/Tool Design

Truly resolving this issue requires the tool or mold itself to be examined for proper vent depths, and addressed as needed.That being said, you'll still need a cleaner to remove the excess gas buildup.

Solution:

Zap-Ox™

Zap-Oxwill remove gas build up in seconds, minimizing downtime.There is no other cleaner that can remove rust, oxidation, buildup, weld discoloration, and other stains as effectively and efficiently as Zap-Ox.

常見原因:

Molding Material

The type of material used in producing the product combined with poor venting within the tool can trap gasses, creating buildup.The long-term solution is pairing the material with the right mold/tool.To address the immediate issue of gas buildup, use a mold cleaner.

Zap-Ox Saves Hours of Tool Maintenance

See Case Study

Used Zap-Ox to clean gassing and burn marks at the end of fill.This saves hours of tool maintenance.Normally, you would have to pull the tool and stone polish or bead blast to remove the gassing from the texture.\u201d<\/p>","tablet":"
