Research in SIMTech

 

Forming Technology Group focuses on R&D in near net shape or net shape manufacturing and rapid prototyping processes for metals, ceramics, polymeric materials and composites. Technologies developed in the Forming Technology Group include metal forming, extreme pressure die casting, powder processing, precision polymer moulding, natural fibre composite and myriads of additive manufacturing processes, all contributing to cost-performance improvement to give local manufacturing industry competitive edge.

Our R&D activities are carried out in three teams:

  • Metal and Ceramic Processing Team focuses on sheet and bulk metal forming and incremental forming, micro surface texturing, Liquid Forging of wrought alloys and metal matrix composites, as well as metal and ceramic powder injection moulding

  • Polymer Processing Team focuses on development of precision polymer injection moulding, natural fibre composite consolidation and forming, and material development for bio-polymers and liquid silicone rubber

  • 3D Additive Manufacturing Team focuses on development of processes and systems for additive manufacturing of metals (powder bed and direct deposition) and polymers (thermoplastic and thermosetting) for highly customized products

The group carries out collaborative cutting-edge research with academic/research institutions. To constantly serve the changing market needs, close collaborations with industrial partners are fostered through co-developing of processes and products, technology transfers and conducting training for the manufacturing industry.
