Walzengiesserei & Hartgusswerk Quedlinburg

What Walzengiesserei & Hartgusswerk Quedlinburg does

Walzengiesserei & Hartgusswerk Quedlinburg GmbH (WHQ) is a specialized iron foundry established in 1865 in Quedlinburg, Saxony-Anhalt, Germany. The company manufactures custom, precision-engineered cast iron components — including metallurgical rolls, roll rings, roller shells, pistons for hydraulic presses, runner rings for edge runner mills, piercing mandrel inserts and dies, and calender, dosing, crushing and grinding rolls — using spheroidal graphite (ductile) iron and chilled cast iron (Hartguss). Production relies on medium-frequency induction melting (in place since 1993), centrifugal casting capability added in 2011 at a second site, and in-house CNC finish machining that delivers ready-to-mount components in weights ranging from approximately 20 kg up to 6 tonnes. WHQ also produces proprietary material grades with pearlitic, bainitic, martensitic, and acicular matrix structures tailored to specific applications, building on a historical 1952 patent (#2339) for the industrial magnesium treatment process enabling spheroidal graphite iron production.

The company serves over 150 industrial partners worldwide across steel (seamless tube and long-product mills), brick and ceramics, food and tobacco processing (chocolate, oilseeds, coffee, feed), hydraulic press manufacturing, and paper industries. Its go-to-market is enterprise field sales with dedicated Key Account Managers conducting on-site visits, supplemented by an international sales representative network, trade show participation, and a 9-language website with a 4-step product configurator that routes inquiries to sales (typical response 1–5 business days). Revenue is generated exclusively through bespoke, quote-based contracts for custom-manufactured components — pricing is non-public and varies by geometry, material grade, hardness specification, and finish — with no standardized price list. A specialized revenue stream addresses obsolescence, producing replacement castings for discontinued machines to extend equipment lifecycles for industrial operators.

WHQ holds DIN EN ISO 9001 (quality) and DIN EN ISO 50001 (energy management) certifications and operates as a private GmbH following a 1993 management buy-out from Treuhand. With only nine employees and an apprenticeship-heavy talent base (over 10% of the workforce in 3.5-year internal training), WHQ functions as a niche, high-craft specialty foundry rather than a scaled industrial manufacturer.

Revenue model

1. Custom cast iron components: WHQ generates revenue through the manufacture and sale of custom precision cast iron components (rolls, roll rings, roller shells, pistons, runner rings, and other wear-resistant parts) made to customer specification. Pricing is quote-based, reflecting the bespoke nature of each order. Products are sold directly to industrial customers globally, with components ranging from 20 kg to 6 tonnes.
2. Replacement and obsolescence components: A specialized revenue stream focused on producing replacement cast components for discontinued machines and obsolete systems. This addresses the obsolescence problem for industrial customers and generates recurring demand from plants needing to extend equipment lifecycle.
3. Aftermarket and service parts: Revenue from the supply of wear parts and consumable cast components for ongoing mill and press operations, often in the context of long-term customer relationships spanning decades.
