Controller retrofit of Bekum BM08

Controller retrofit of Bekum BM08 with wall thickness regulation and bottle verification

Situation

There are almost no more replacement parts available for the originally installed Philips PLC. The Bekum or Bosch amplifier cards used for the servo-valves are also difficult to obtain. Parts available on the market and used parts are very expensive and their lifespan is not predictable.

Requirement

The requirement of our customer was to make their installation functional again for the next years from the point of view of control, thanks to this retrofit. A high reliability is crucial to them.
In order to arrange for a cheap retrofit, it was agreed to install the new PLC in the available electrical cabinet and to integrate the still up-to-date controller components.

Controller retrofit on SIG Blowtec Machine BLOWTEC SB 8

Controller retrofit on SIG Blowtec Machine BLOWTEC SB 8
with sequential coextrusion, radial gap adjustment and suction blow moulding.

Situation

The operation of the SIG Blowtec SB8 installation was vulnerable to faults and very slow. The available PLC program of the hydraulic and pneumatic slider could no longer be modified. Adjustments to required sequences were implemented in a complex manner by manual re-wiring at the valve plugs or through small additional controllers.

The PLC was a mixture of Beckhoff and Siemens components. Missing support from machine manufacturer, according to the customer.

Requirement

For the customer, it was important to have a contact and service partner that deals in detail with the operation of these machines for this complex coextrusion installation. The mix of Siemens, Beckhoff and further small controllers is to be eliminated in order to relieve the maintenance department. The customer already knew our clear visualisation pages and in particular the flexibility of our slider controller thanks to prior controller retrofits, e.g. on Battenfeld BFB8 machines.
