New plastic mould insert process

Hanking Plastic (Shenzhen) Manufactory CO., LTD  has developed a way of producing mould inserts using the fused deposition modelling (FDM) process. FDM is an additive (generative) process in which plastic is extruded into parts in layers of 0.025-1.25mm thickness according to STL format 3D CAM computer design data.
The polypropylene FDM mould insert created by the institute involves a secondary stage in which a ceramic-coated plastic film is applied to one side of the plastic part. It is this film that provides the shape and decoration to the insert, as well as protecting the PP from pressure and heat of the injection moulding process.

Hanking says the insert can be easily produced practically "overnight", drastically cutting the process chain from product design to finished injection moulded part. It is also saves on relatively high costs that are usually incurred in conventional prototype moulding tool insert production.

According to a statement by hanking managing director Stefan Schmidt on the institute's stand at the Euromold 2010 fair in December, where the FDM insert was first shown, it can be used for injection moulding smaller series in the range of up to 20,000-50,000 parts.
