Resin Transfer Molding Rtm Mold

 Resin Transfer Molding is a higher tech process used to produce products featuring very high fiber/resin ratios.  The goal in most cases is to produce a finish on both sides instead of just one. RTM labor costs are lower than hand lay-up, and volume is higher.
Two matching female & male tools are used.  The female tool is gel coated as prescribed by our customer to a specific color.  Pre-cut fiberglass is then laid out in the female side.  The matching male tool is now 'forced' into the female tool with hydraulic pressure and secured.  Once both tools are secured, resin is forced through the fibers by vacuum.  When completed the male end is lifted out and the finished part is ready to remove.





 Describtion:

1st:Mould treatment: 
Polish: Mould must be polished before production which will guarantee the good and solidified surface
Clean: Special detergent are used to get the dust away from the mould which will make no dark markings in the
 gel coat surface. 
Release agent: This will be brushed on the mould to make ejection easily.

2nd Fiberglass and resin:
Gel coat: The color of products is decided by the gel coat,with thickness of about 0.3-0.5mm. UV resistant can
be added. 
Surface mat:  This is to avoid the air bubble on the surface, and also make fiberglass mat invisible from the finished
surface. 
Fiberglass mat: Normally we use 300g/m2 (0.6mm thickness) and 450g/m2 (0.9mm thickness). According to your
requests on the  thickness and strength, we will calculate how many layers of fiberglass mat should be used.


3rd
Solidify:  The time required for solidifying depends on thickness and weather condition.Normally 24 hours for one
piece to solidify to avoid any deformation after demoulding. 
Demould: After solidified, the product will be demoulded
Cut and trim:  We will mark the trim line and hole positions on the mould,then trim according to the marks to
gaurantee the mounting dimensions
