Büchler Reinli + Spitzli AG (BRS) is an owner-managed Swiss tool- and mold-making company based in Flawil in the Canton of St. Gallen. Tracing its origins back to the establishment of Büchler AG in 1966, the firm is a premier manufacturer of high-performance injection molds, die casting molds, and precision mechanical components.
BRS integrates engineering consulting and in-depth Design for Manufacturing (DFM) reviews into early product development. By examining parting lines, gate designs, wall thickness distributions, sink mark risks, draft angles, and undercut geometries, BRS assists customers in minimizing tooling modifications, optimizing cycle times, and decreasing overall piece-part production costs.
- Certified according to ISO 9001:2015 and ISO 14001:2015
- EcoVadis Bronze medal recipient and esg2go sustainability certified
- Operating across three core divisions: Tool & Mold Making (W), Service & Revisions (S), and Precision Parts Manufacturing (P)
BRS provides full-service tooling development and precision machining solutions:
- Design for Manufacturing (DFM) Analysis: Detailed manufacturability analysis of part geometries covering mold separation, gating systems, nominal wall thicknesses, sink mark avoidance, draft angles, undercuts, transition radii, and functional tolerances.
- Molds & Tooling: Engineering and construction of high-performance injection molds for thermoplastics, thermosets (duroplastics), biopolymers, Metal Injection Molding (MIM), and die casting, as well as thermoforming and stamping tools.
- Precision Machining & Fabrication: Multi-axis CNC milling, precision turning, surface and cylindrical grinding, wire EDM, and die-sinking EDM for hardened tool steels and complex geometries.
- Tool Maintenance & Revision: Comprehensive overhaul, maintenance, component modifications, and repair of in-house and third-party molds.
- Precision Spare Parts & Fixtures: Production of interchangeable mold inserts, spare part sets, custom mechanical components, and inspection fixtures.
