GLASSWORKS EQUIPMENT LIMITED

What GLASSWORKS EQUIPMENT LIMITED does

Glassworks Equipment Limited, trading under its parent entity Glassworks Hounsell Limited (Registered Company Number 00371181), is a UK-based precision engineering company specializing in equipment for the glass manufacturing industry. Founded in 1964 with electrodes first supplied to the glass industry in 1969, the company operates from Halesowen, West Midlands, with manufacturing in Birmingham, UK, and holds ISO9001 certification. It is positioned as a world leader in glass melting electrodes, with over 50 years of accumulated operational data from varied furnace applications.

The company's core product is the Stannex range of tin oxide electrodes for electric glass melting, manufactured from pure tin oxide via isostatic pressing and sintering (no recycled or reclaimed material). Electrodes are supplied as rods (standard diameters 10-200mm, up to 650mm length) and blocks, available in four proprietary material grades (Stannex D, E, ELR, ELR-X) formulated for different glass types and connector requirements, with temperature resistance exceeding 1780°C and applicability to furnace outputs from 1-160 tonnes per day. The product portfolio is completed by precision-matched connector systems (Lateral Plug, Metallic Plug, Back Face, Silver Rod, and Advancing System connectors) and in-house manufactured batch charging systems (X-Y, Boom, Screw/Twin Screw, and Spoon chargers). Applications span TFT/LCD, optical/ophthalmic, lead crystal, specialty, and redox-sensitive glass manufacturing, as well as forehearths, refiners, and conventional furnace boosting.

Revenue is generated through quote-based B2B sales of custom-manufactured hardware, with no public pricing and direct enterprise engagement with technical buyers. The go-to-market combines direct sales from the UK headquarters, regional channel partnerships (notably BDM Metals in China), participation in international trade exhibitions (e.g., China Glass 2019 in Beijing), and cross-referrals with sister companies Glassworks Engineering and Glassworks Hounsell Limited. Geographic reach spans Europe, South America (Argentina, Brazil), the Middle East (UAE), Russia, and Asia Pacific (China). A secondary revenue stream provides bespoke precision engineering — leveraging in-house CNC machining capacity including a large-bed VMC with 10,000kg capacity — to non-glass industries including printing, packaging, confectionary, marine, defence, aviation, aluminium, and oil and gas.

Core offering

Glassworks Equipment designs and manufactures Stannex tin oxide electrodes (rods and blocks), precision-matched connector systems, and batch charging systems for electric glass melting furnaces. All products are manufactured in-house at the company's Birmingham, UK facility under ISO9001 certification, with four proprietary tin oxide material grades tailored to different glass types (lead crystal, TFT/LCD, optical, specialty) and furnace outputs ranging from 1 to 160 tonnes per day. The company also supplies custom precision engineering components for adjacent industrial sectors including printing, packaging, marine, defence, aviation, aluminium, and oil and gas.

Product overview

GLASSWORKS EQUIPMENT LIMITED is a precision engineering company and world leader in glass melting electrodes, specializing in equipment for the glass manufacturing industry. The core product portfolio centers on Stannex Tin Oxide electrodes for electric glass melting, available in two main forms: rods (diameters 10-200mm, up to 650mm length) and blocks (preferred sections 100x100mm, 100x150mm). These electrodes are complemented by four material grades (Stannex D, E, ELR, ELR-X) designed for different glass types and connector requirements. The product line includes compatible connector systems (Lateral Plug, Metallic Plug, Back Face, Silver Rod, Advancing System) and batch charging systems (X-Y Chargers, Boom Chargers, Screw/Twin Screw Chargers, Spoon Chargers) for various furnace types. All products are manufactured in Birmingham, UK with ISO9001 certification, and are used in melting, refining, and boosting processes for TFT/LCD, optical, ophthalmic, lead crystal, and specialty glasses.
