Abstract

In paperboard press forming the forming forces are transmitted on the
formed substrate by controlling the sliding of the blank with a blank
holding force. A set value of the force and the friction between the
tool surfaces and processed material define the force transferred on the
formed substrate. Mould surface roughness is one of the main factors
affecting the magnitude of friction and maximum usable press force. A
series of surface roughness measurements was made to investigate the
surface roughness in different areas of two different blank holders to
determine a sufficient quality for the tool surfaces. Also the static
friction coefficients of formed substrates were determined and the
friction force distribution was investigated. The results show that the
effect of mould temperature on friction force can be reduced
significantly by mould surface polishing, while making the press-forming
process more predictable and easier to adjust due to reduced variation.
Hence, the polishing of mould surfaces can be recommended.
