Light resin transfer molding.
Light resin transfer molding lrtm a variation of the vacuum infusion process appeared about 10 years ago as mold flexible counter molds were developed along with improved materials and equipment.
These closed molding processes are changing the industry.

The process is best suited for high precision parts where a two sided finish is required and for moderate production quantities ranging from 100 to.
Light rtm also offers lower tooling costs.
Transfer molding bre moulding is a manufacturing process in which casting material is forced into a mold 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.
Our extensive experience with light resin transfer moulding lrtm enables us to produce innovative and cost effective parts for our oem customers including alstom and bombardier transportation.
Light resin transfer molding light rtm is a closed mold system that consists of an a side base mold and a semi rigid fiberglass b side mold or counter mold.
Compared to injection molding transfer molding uses higher pressures to uniformly.
The rtm light process also know as lrtm eco vacuum molding vartm for fiber reinforced composites has recently taken the lead as the most popular closed molding process for low to medium volume applications.
This leading technology has now displaced the former conventional or traditional rtm process in most typical marine automotive industrial and medical composite molding.
The closed mold consists of an a side mold base mold and a semi rigid b side mold counter mold that is sealed to the a side mold using vacuum pressure.
But lrtm requires less costly tooling and can still provide excellent cosmetics on both sides of a part in an efficient manufacturing process.

To survive and thrive will require adjusting shop processes and acquiring new skills.
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.
Light rtm light resin transfer molding is a closed mold process that utilizes coordinating a side and b side molds to create a part with consistent thickness a smooth b side surface and controlled fiber resin ratios.
Like other closed molding composites processes light resin transfer molding lrtm offers reduced waste and emissions efficient materials use and a consistent and repeatable process.
Jhm technologies was born in may of 1990 with the goal of producing rtm injection systems that would allow closed molders the highest level of process control possible.
