SWX mold tools are geared toward plastics injection. Are there any composites manufacturers on the forum who use SWX for designing LRTM molds? Any good resource suggestions?
Hey now.. I think you're the guy Rick Casey needs for this project!?..
Rick Casey ,.. I've only helped with some modeling for LRTM and similar vacuum molds (also RIM and Vacuum Forming).
I could be wrong (there could be?) but I have not seen or heard of software which is specific for this type of molding workflow?
So,.. you may need to develop your own workflow (material thicknesses, gaps, flange, channels, seals..) for your company?
btw, I think mold making and other mold technologies all have a certain degree of specialization and black magic.. so, SW features are very basic, as you and may know.
Could you attach a example?
Your process is something like this?

Like I see at the basic SW will be a correct choice to you....something like this.....
Similar to that. RTM relies on the resin being forced into the mold via injection. The molds are held together by clamping or hydraulics. LRTM involves applying vacuum to the mold flanges to clamp the molds together. A separate vacuum is applied to the cavity of the mold. Resin is forced in by atmospheric pressure (similar to vacuum infusion) and also forced in by injection. There are several variations on this process. The molds are a bit more complicated as they require gaskets for sealing, grooves for "venting"
Nice projet....if you need a little help we could assist to you ... Paul Salvador has huge expertise on surfaces....
You're right, Paul Salvador. All I have been able to find is Flowsim, super expensive and seems more geared toward CFD than molding workflow. Even though closed mold composite manufacturing has been around for quite awhile it seems like a niche industry sometimes. Looks like I will just have to keep learning everything I can about surfacing and hybrid modeling. I want to up my game and be able to develop my own workflow like you said. Lucky for me there great people to turn to for advice on the SWX forum.
Hello Rick,.. yeah, creating your own workflow or some common base from past generations is the best way imho.
I have not used any vacuum flow simulation software,.. after doing a search,.. looks like there are some apps out there..
