Slévárny Třinec

What Slévárny Třinec does

Slévárny Třinec, a.s. is a traditional Czech foundry manufacturer, founded in 1842 in Třinec and operating as a 100%-owned subsidiary of the Třinecké železárny – Moravia Steel group since 1999. The company produces castings in steel, grey iron (flake graphite), ductile iron (spheroidal graphite), and non-ferrous metals, with annual capacity of up to 40,000 tonnes across two cast iron foundries and one steel foundry, supported by in-house model production (5-axis CNC milling, 3D modelling, 3D printing), a casting machining centre, and heat treatment facilities. The company employs 500–650 staff and operates from a single integrated site at Průmyslová 1001, Třinec.

The company's commercial customer base spans eight primary industrial verticals: railway (Deutsche Bahn- and ČD-certified for sleeper connecting plates, crossing components, and base plates — its primary segment), shipbuilding, metallurgy, rolling mill, automotive, mining and raw materials processing, engineering and energy (including wind turbine castings), and material handling (counterweights). It holds an unusually deep set of certifications for an independent foundry, including EN ISO 9001, EN ISO 14001, EN ISO 3834-2, EN 15085-CL1, PED 2014/68/EU, Deutsche Bahn AG supplier certification, DEKRA Rail certification, and Czech Railways (ČD) supplier certification, which together form a meaningful barrier to entry in safety-critical rail and pressure-equipment end-markets.

The business model is a sales-led B2B industrial foundry: castings are produced to customer specification and priced on a quote-per-order basis, with one-time product sales rather than recurring subscription or licensing revenue. More than 60% of production is exported to 20 countries worldwide, with dedicated in-house sales, purchasing, shipping, and invoicing functions supporting direct enterprise relationships. Value is captured not only through casting output but also through downstream finishing services — including machining, painting, chemical and mechanical testing, defectoscopy, radiological and acoustic inspection, 3D scanning, blasting, and heat treatment — which raise the proportion of revenue from finished or semi-finished components relative to raw castings.

The 5–150kg segment runs on an automated HWS moulding line, with larger pieces moulded manually. Sold to industrial customers in automotive, railway, mining, metallurgy, and engineering sectors.
• Grey Iron Castings (Odlitky z šedé litiny) Iron castings with flake graphite (grey cast iron) produced per ČSN EN 1561, available in weights from 5kg to 35,000kg with minimum wall thickness of 7mm. Manual moulding covers 50–35,000kg pieces while an automated HWS line handles 5–150kg pieces. Sold to industrial customers across metallurgy, rolling mills, machinery, and engineering sectors.
• Steel Castings (Odlitky z ocelí) Steel castings in weights from 5kg to 16 tonnes with minimum wall thickness of 10mm, including non-alloy carbon steels, low-alloy steels, heat-resistant Cr and CrNi steels, high-alloy Mn steels, abrasion-resistant Cr cast iron, tool steels, stainless steels, and steels for rollers. Sold to industrial customers in shipbuilding, metallurgy, energy, and engineering sectors.
• Production of Models (Výroba modelů) In-house model-making service using 5-axis CNC milling, 3D modelling, and 3D printing to produce model equipment for hand and machine moulding.
