Schmiedetechnik Plettenberg

What Schmiedetechnik Plettenberg does

Schmiedetechnik Plettenberg GmbH & Co. KG (STP) is a privately held German precision-forging and machining company headquartered in Plettenberg, North Rhine-Westphalia, with five German production sites and a 49%-owned joint venture in India. It produces forged and machined components — primarily gear components, connecting rods, ring-rolled bearing races and chassis parts — for automotive (73% of turnover) and non-automotive customers including Deutsche Bahn-approved railway infrastructure, off-highway, defense, agricultural and construction machinery. The core manufacturing platform combines closed-die forging on hammer and press lines up to 4,000 tonnes, ring rolling with inline heat treatment, the proprietary +P process for AFP/bainitic steels, CNC machining across 130 machines, deep-hole drilling, gear cutting and broaching, yielding more than 10 million forged parts and 3 million machined components annually from 31,000 tonnes of steel. Revenue is generated through B2B quote-based hardware sales of ready-to-install components, distributed via a direct enterprise field-sales force (with regional reps in Sweden, Italy and China) and supplemented by a joint venture with Hero Motors — Munjal STP Industries in Ludhiana, India — to serve 2- and 4-wheeler drivetrain demand. The business is qualified to IATF 16949, ISO 9001/14001/50001 and TISAX standards and operates from a vertically integrated German footprint of approximately 600 employees across the STP Group.

Core offering

Schmiedetechnik Plettenberg (STP) manufactures precision-forged and machined metal components through four strategic business areas: Gear Components (output gears, CVT gears, front axle and side shafts), Connecting Rods (for cars, trucks and motorcycles), Ring Rolling Products (crown gears, bearing rings), and Non-Drivetrain/Chassis components, plus Deutsche Bahn-approved railway track components. Production combines closed-die forging, ring rolling, CNC turning/milling, deep-hole drilling, gear cutting, broaching, and in-line heat treatment (including the proprietary +P process) to deliver ready-to-install parts at high volumes to automotive OEMs, tier suppliers, and non-automotive industrial customers.

Product overview

Schmiedetechnik Plettenberg (STP) is a precision forging and machining company serving the automotive and non-automotive sectors. The company operates as a unified manufacturing platform combining three core capabilities: (1) closed-die forging and ring rolling for raw part production, (2) comprehensive machining including turning, milling, deep-hole drilling, gear cutting, and broaching, and (3) integrated heat treatment including the +P inline process. STP's product portfolio centers on four strategic business divisions—Gear Components (Getriebekomponenten), Connecting Rods (Pleuelstangen), Ring Rolling Products, and Non-Drivetrain Components—supplemented by Railway Components for rail infrastructure. The company runs five production locations in Germany (Plettenberg Plants 1 and 3, Werkzeugtechnik Plettenberg, Sequatec in Bad Emstal, Wärmetechnik Halver) and one joint venture in India (Munjal STP Industries). Annual production capacity exceeds 10 million forged parts and 3 million machined components processed from approximately 31,000 tonnes of steel.
