Sovrin were asked to adopt an existing mould tool to deliver improved product quality. The service and quality provided persuaded the customer to place a suite of new mould tools with increased cavitation.
Sovrin Plastics, the UK-based medical and technical moulder and
specialist in the manufacture of micro moulds and moulded components,
has become the first UK user of the new Sodick Premium AP1L die sink
EDM (electrical discharge machining) - only the second machine of its
type to be installed in Europe.
The system will be used at Sovrin's facilities in Slough,
which include six Class 7 (10,000) cleanrooms (1600sq m), that house
its technical plastic injection moulding and state-of-the-art CAD/CAM
and CNC tooling divisions.
The company's micro-mouldings have found an increasing
demand in the medical, pharmaceutical, telecommunications and
electronics industries. A micro-moulding cell has been designed
specifically for producing the smallest components, typically with
component weights below 0.25g and down into single figures of
"We selected (Sodick's) machine after extensive trials at
Sodi-Tech in the UK and at Sodick's headquarters in Japan," said
Sovrin's founder and MD, Peter Joiner. "One such trial demanded the
creation of various pin-gates measuring between 0.1 and 0.15mm in
diameter - the way the Sodick machine handled the task was excellent.
Other tests showed that electrode wear was also significantly reduced,
in one instance to 0.005mm."
EDM contouring with the Premium AP1L provides die-sinking
EDM with the dynamic response of linear technology and therefore offers
many associated advantages: reduced electrode costs, electrode shape
independent of cavity, accurate forms and shapes, and EDM direct
milling of the cavity, Sodick says.
"The toolchanger has made a world of difference to our
toolroom operation," says Mr Joiner. "We can now setup and leave jobs
to run unattended overnight, achieving genuine 24 hour production."
