What is RTM in manufacturing?

Resin transfer molding (RTM) is a closed-molding fabrication process where UPR is transferred over already-placed reinforcement fibers (glass fiber, carbon fiber, aramid fiber, and natural plant fibers such as sisal, banana, nettle, hemp, and flax) which are then placed on the surface of a mold.

What is the difference between transfer molding and compression molding?

Transfer molding is different from compression molding in that the mold is enclosed [Hayward] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact. Compared to injection molding, transfer molding uses higher pressures to uniformly fill the mold cavity.

What do you need to know about lrtm?

The LRTM process basically only requires an injection or proportioner system, a vacuum system and the mold itself. This is showing the Flex Molding process, a variation of LRTM, with a re-usable membrane counter mold.

What kind of molding is used for lrtm?

A good rule to live by is “Design for the Process,” regardless of which process you use. LRTM mold sets consist of a rigid “A” mold that is solidly reinforced and a semi-rigid “B” mold. The “A” mold is made with high temperature and low shrink resin. The “B” mold is semi-rigid and retains a small amount of flexibility.

What do you need to know about light RTM?

With traditional RTM, we are feeding the mold cavity with resin under moderately high flow rate and pressure that is only limited by the structural ability of the molding tool and perimeter clamping or press system to sustain mold closure.

What is the injection pressure of RTM light?

Normally, this limits the injection pressure of the RTM Light to less then 1 bar (14 psi) with the cavity held at a constant vacuum level of -.5 bar (15″ hg)
