Flame sprayed
Note: This method is currently only suitable for prototype tooling
Reasons to Use
- Very short lead-times can be achieved
- Well suited to small to small/medium sized mouldings
- High accuracy of cavity dimensions, form and surface definition.
Method of manufacture
A model (with casting contraction and moulding shrinkage added) has zinc flame sprayed on to it. External flanges and other details may be also sprayed on. Unlike tools made for injection moulding and blow moulding there is no need to back up the flame sprayed shell with other materials to give strength and to form the bolster.
Composite
Note: This method is currently only suitable for prototype tooling
Reasons to Use
- Very short lead-times can be achieved
- Well suited to small to small/medium sized mouldings
- Good accuracy of cavity dimensions and form.
Method of manufacture
A model is made (with moulding shrinkage added) onto which the pieces of the tool are laid-up by hand using high temperature grades of epoxy resin with carbon fibre reinforcement.
