Vesconite used to replace phosphor bronze platen guide bushes on blow moulding machines.

A company producing expanded polystyrene (EPS) foam moulded products kept encountering problems of final product
contamination, caused by the lubrication necessary for sliding operation of the bronze bushes installed in the
platens of their equipment. The EPS moulding machines used by this company are all EA Heitz equipment.
Lubrication had to be eliminated to prevent contamination and rejection of client products.

Vesconite self-lubricating bushes were installed into the platens. These bushes guide the platen along hard
chromed columns when clamping action takes place. Owing to the ability of Vesconite to operate unlubricated,
any contamination of the moulded products through contact with the columns or from dripping lubricants is
eliminated, as the columns are free of any oil or grease.
The long service life of the Vesconite bushes and the freedom from maintenance is ensured even at higher cycle
sequences and in continuous operation.
- no rejects caused by contamination
- savings on lubricants
- less downtime of machines
- reduced maintenance costs
- longer life for the hard chromed columns
