Vacuum Infusion

Vacuum infusion is a fabrication technique that uses vacuum pressure to drive resin into a laminate. Dry materials are laid into the mold and the vacuum pressure is applied before resin is introduced. Once a complete vacuum is achieved, resin is forced into the laminate via vacuum tubing. The vacuum infusion process offers a better fiber-to-resin ratio than hand lay-up or vacuum bagging.

EnkaFusion Nylon Flow Media
Fastest Resin Infusions

Our #1401 EnkaFusion® Nylon Flow Media offers the fastest resin flow rates. Made of randomly oriented and entangled nylon filaments, this flow media limit resin retention and can be used on the surface or as an interlaminar media. This product is compatible with all of our resins and is available in multiple roll lengths, all rolls are 39" Wide. 
Green HDPE Infusion Flow Media
Quick Controlled Channels

Our #1406 Green HDPE Infusion Flow Media is most commonly used for medium to large sized resin infusion projects up to 90sqft that require quicker resin flow. This flow media assists resin flow through your part during the resin infusion process and can be used in temperatures up to 200 degrees Fahrenheit. Quick resin flow is typically desired in order to properly infuse the entire part.

Our Green HDPE Infusion Flow Media can also be used on larger projects if multiple ports and flow channels are used while still offering predictable, controlled resin flow. With exceptional conformability, this HDPE does not fray or roll up when cut, making it easy to position in the vacuum bag. This product is compatible with all of our resins and is available in multiple roll lengths, all rolls are 42" Wide.  
Red LDPE Infusion Flow Media
Controlled Resin Channels

Our #1405 Red LDPE Infusion Flow Media is used for small to medium resin infusion projects, up to 50sqft, that require predictable, controlled resin flow. This flow media is designed to assist resin flow through your composite part during the resin infusion process.

In addition to having a high degree of conformability, this LDPE does not fray or roll up when cut, making it easy to position within your vacuum bag. This flow media can also be used on larger projects if multiple resin ports are installed on a single part. With a service temperature of up to 160 degrees Fahrenheit, #1405 is compatible with most composite manufacturing techniques and all of our resins. It is available in multiple roll lengths, all rolls are 60" Wide. 
DIVINYMAT
Structural Flow Media

Our #1024 Divinymat was engineered specifically for vacuum infusion. Featuring grooves, perforations, and cross scoring, this core material creates flow channels for resin while adding strength. Divinymat is a 3.8lb DIAB Divinycell® H with cross scoring and offers the highest structural properties of any available flow media. Bonded to a light scrim cloth, this core will conform to most simple curves and shapes. Sold by the sheet, each sheet measures 1/8" thick x 32" x 48".  
Spiral Tubing
Extend Vacuum/Infusion Lines In Bag 

Our #1403 1/2" Spiral Tubing is used in both the vacuum bagging and resin infusion processes. A vacuum infusion standard, this tubing is ideally suited for in-bag vacuum line extenders or resin feed lines. To ensure flow is not impeded, we recommend wrapping spiral tubing in nylon or polyester peel ply. Our tubing is 1/2" ID and is compatible with all of our hose fittings. 
EnkaFusion Filter Jacket
Create Fast Resin Channels

Our #1400 EnkaFusion Filter Jacket is used during resin infusions to create fast-moving channels of resin that permit a wider dispersion path and more even infusions. With a three-dimensional "V" shaped nylon mat core contained within a polyester "sock", EnkaFusion Filter Jacket is fast and easy to set up using our #906 Plastic T Fittings.
4" Wide.   
Lantor Soric® XF
Conformable Flow Media

Our #1408 and #1409 Lantor Soric® XF are the most conformable of our flow media. This product features a unique design of hexagonal flow channels on a carrier sheet to create a steady, even resin front without sacrificing surface finish or material conformability. #1408 is 2mm thick while #1409 is 3mm, both are offered in 50" wide rolls. This product quickly builds thickness with up to 35% less resin retention than all-glass laminates. Lantor Soric® is compatible with all of our resins and reinforcements. 
Vacuum Infusion Trial Kit
All You Need to Kick-Start Resin Infusion


Once you have experience vacuum bagging and molding at room temps, it's natural to move on to vacuum infusion. This kit is designed to familiarize you with the process, and help you make informed decisions about choosing flow media, placing and using spiral tubing, and designing successful experiments for your own future projects. It contains enough material to build three infusion trial projects, up to 24" x 13" each:
  • One laminate using EnkaFusion Nylon Matting flow media
  • One laminate using Lantor Soric® flow media
  • One laminate using Divinymat® Sandwich Core flow media

In order to use the kit, you will need the follwing: your own vacuum pump, bagging materials, and vacuum tubing to attach to the bag; your own resin and reinforcement; and, ultimately, a mold with a relatively large flange to make a laminate no larger than 24" x 13".

Kit includes:
  • #505-A Resin Bucket 1 Gallon (x3)
  • #512-B Resin Line Holder (x3)
  • #893 Vacuum Tubing 5'pieces (x3)
  • #1601 Zip Strips (x6)
  • #1400 Filter Jacket 5" (x3)
  • #582 Peel Ply 5'x5" pieces (x3)
  • #1024 Divinymat® 24"x16"
  • #1401 Nylon Matting 24" x 13"
  • #1605-A Flow Regulator (x2)
  • #1606-A Spring Clamp
  • #906-A T-Fittings (x6)
  • #1400 Filter Jacket 18" (x3)
  • #1403 Spiral Tubing 5' pieces (x3)
  • #582 Peel Ply 20" x 5" pieces (x3)
  • #1409 Lantor Soric® 24" x 16.37"
  • Instruction Sheet
 
Resin Trap
Protect your Pump

Don't let resin from the vacuum infusion process destroy your pump. This 2½ gallon stainless steel vacuum sealed tank is installed between the mold and the vacuum pump to capture excess resin that enters the vacuum line before it can damage your equipment. For a large project, or if your resin isn't infusing evenly, you can install multiple resin traps in-line. Be sure to apply mold release to all interior surfaces of the resin trap prior to lay-up so that after your infusion is complete, your cured resin will remove cleanly. Comes complete, including vacuum gauge, barbs for use with 1/2" Vacuum Tubing, and instruction manual.

Measures 17" H and 12" W. 2.5 gallon capacity.
