What Stamixco AG does

Stamixco AG is a privately held Swiss specialty industrial manufacturer headquartered in Wollerau, Switzerland, focused exclusively on static mixing technology. The company designs and produces static mixers — components containing fixed internal geometry that mix flowing media without moving parts — for three primary end markets: plastics processing (injection molding and extrusion), general chemical/industrial mixing, and food and pharmaceutical applications requiring sanitary or corrosion-resistant construction. Its core technology is the proprietary X-Grid (X-Gittermischer) mixing geometry, supplemented by helical, SMB-series, and Flowte-B element designs, with the product set spanning individual mixing elements, welded mixer rods, complete housings, micro mixers down to 1.7 mm, and integrated polymer melt coolers. Materials expertise is a notable technical dimension: the company produces mixers in stainless steel, Hastelloy, Tantalum, pure PTFE, and acid-resistant plastics (PP, PVC, PA66), enabling service in highly corrosive chemical and electropolished sanitary applications.

Stamixco monetizes primarily through custom-quotation hardware sales — mixers sold as elements, rods, or complete assemblies with customer-specific housings and ancillary pump/control/dosing systems. Pricing is not publicly disclosed and varies by mixer type, nominal width, material, element count, and configuration; the company also generates a smaller stream of consulting/advisory revenue supporting Sulzer Mixpac following the July 2020 sale of its disposable mixer business. Go-to-market is direct enterprise field sales supported by major international trade show presence (K Messe, NPE, Fakuma, Swiss Plastics) and a German-language website with downloadable technical data sheets; no e-commerce, channel partners, or digital marketing programs were identified. The customer base is a horizontal mix of industrial polymer processors, chemical companies, and sanitary-process manufacturers, with BASF disclosed as a named enterprise reference. The company operates with 1-10 employees, has no disclosed funding history, no parent company, and no M&A activity beyond the 2020 divestiture to Sulzer Mixpac.

Core offering

Stamixco AG designs, manufactures, and sells static mixers for industrial applications across four product categories: injection molding mixers (SMN series), extrusion melt mixers (SMB series), general mixing technology (GXM, GVM, Flowte-B, Helical, Inline), and specialty products including the SMH polymer heat exchanger cooler and micro mixers. The company also provides custom-designed mixer housings, pump/control/dosing systems, and technical consulting services, leveraging its proprietary X-Grid mixing geometry to serve polymer processing, chemical, food, and pharmaceutical industries.

Product overview

Stamixco AG is a Swiss company specializing in static mixing technology, offering a comprehensive portfolio of mixing solutions organized into four main product categories: mixing systems for injection molding (SMN series with mixing elements and protective filters), mixing systems for extrusion (SMB series melt mixers), general mixing technology (GXM, GVM, Flowte-B, inline mixers, helical mixers), and specialty products (SMH heat exchangers, micro mixers, chemical mixers, custom pump/control systems). The company also previously offered disposable mixers (GXP-H, GXF-21, GXP, GXR-P, Helical series) under the X-grid mixing geometry, but this business was sold to Sulzer Mixpac in July 2020. Stamixco serves diverse industries including plastics processing, chemical, food, and pharmaceutical sectors, with products available in various materials including stainless steel, Hastelloy, Tantalum, PTFE, and acid-resistant plastics. The company provides both individual mixing elements and complete assemblies including custom-designed housings.

Products and services

• SMN Mischersatz Mixer set with 8 mixing elements for injection molding applications, installed in mixing nozzles directly before the tool to achieve high quality standards with lowest rejection rates.
• SMN-GPD Mischersatz Mixer set with 7 mixing elements and 1 grid protection ring (GPD) that protects static SMN mixing elements from damage during cold starts.
• SMN-SMF Mischersatz Mixer set with 6 mixing elements and 1 melt filter (SMF) that filters unwanted solids when processing regenerates, protecting injection nozzles, hot runner systems, and tools.
• SMB-R Schmelze-Mischer Melt mixer set with 8 mixing elements for extrusion applications, homogenizing polymer melt immediately before forming by equalizing temperature and concentration differences of dyes and additives.
