OLMAS Corrugator — Confirmed & Available Data
The OLMAS corrugator is a robust, industrial-grade forming unit designed for the production of single-wall corrugated pipes used in electrical conduit, drainage, agricultural, and cable protection applications. OLMAS Srl, headquartered in Carate Brianza (MB), Italy, has been manufacturing corrugator systems for over 40 years and is one of Europe's most established specialists in corrugated pipe extrusion equipment.
This unit is equipped with a full set of steel mould blocks covering a range of diameters from approximately 10 mm to 50 mm. The machine frame is finished in blue with grey panels, typical of OLMAS production from the 2000s. Key visible components include pneumatic ejector cylinders, linear guide rails with pneumatic actuators, automatic lubrication (CMV unit — confirmed on photographs), air/water FRL units (SMC brand), and a dedicated on-machine electrical junction box.
The mould block circuit is of the classic horizontal chain-type design, with blocks travelling forward through the forming zone and returning underneath the machine frame. Water cooling channels are built into the mould blocks for efficient heat extraction. The machine is sold complete with its full existing mould block tooling set, offering immediate production capability for the buyer.
What This Machine Offers
Complete Mould Block Tooling Set
A large quantity of numbered steel mould blocks in multiple diameter sizes (approximately 10–50 mm) is included — stored in two wooden crates. Eliminates the significant cost and lead time of sourcing tooling separately.
Steel Mould Blocks — Durability & Precision
All mould blocks are machined steel with integrated spring-loaded interlocking mechanism, ensuring consistent block alignment and tight forming tolerances throughout the production run.
Siemens PLC with Touchscreen Panel
OLMAS standard control architecture — Siemens PLC unit with touchscreen interface for continuous monitoring of operating parameters, speed adjustment, and synchronisation with the upstream extruder.
Automatic Lubrication System (CMV Unit)
An automatic lubrication unit (CMV brand, CE marked) is mounted on the machine frame, ensuring continuous lubrication of the guide rails and chain mechanism without operator intervention.
Pneumatic Ejector Cylinders
Air-driven push-off cylinders handle mould block ejection at the return end of the circuit — a standard OLMAS feature ensuring smooth, reliable block cycling at production speed.
SMC Air Preparation Unit
An SMC FRL (Filter-Regulator-Lubricator) unit with pressure gauge is mounted on the machine underframe — providing clean, regulated air supply to all pneumatic actuators.
