RTM - Resin transfer molding method

RTM method is used a frequently application for many sector as marine, automotive etc. at composite industry .

The advantages of the RTM Applications

• Low styrene emission (near zero)
• Low investment costs (1,000 - 30,000 pieces per a year)
• Both sides smooth product
• Standard sizes products
• Mass production
• Allow use of filler
• Ease of controlling the production process
• Last curing (post-curing) process is unnecessary

Use of resin infusion principle developed various production methods. These methods are standart RTM, light RTM, vacuum-assisted RTM VARTM and infusion.

The advantages of light RTM to standart RTM.
• Lower mold costs. Standard RTM, is a suitable method for the production of smaller quantities of manufactured parts.
• Molds manufacturable from composite materials at light RTM. In addition to this the vacuum use to close the mold helps to move across of resin in the mold.
• Molding pressure is lower than standard RTM
INFUSION METHODS

Consumables of infusion

Resin infusion
