Another commonly employed low-cost organic filler is coconut shell flour. This can be incorporated into the moulding composition in large quantities and this results in cheaper mixes than when woodflour is used. The mouldings also have a good finish. However, coconut shell flour-filled mouldings have poor mechanical properties and hence the filler is generally used in conjunction with woodflour. 

LRTM In this process, the upper mould is made from a semi-transparent composite shell, sometimes supported by a steel structure. Advantages include lower tooling costs and shorter production cycles.
