Roberts Sinto is currently seeking a No-Bake/Airset Foundry Field Service Technician to join our Team in Grand Ledge, MI
What You Will Do
As a No-Bake / Airset Field Service Technician, you are the technical authority and face of Roberts Sinto on customer foundry sites. You will lead the installation, commissioning, calibration, inspection, repair, and full mechanical/electrical rebuilds of both Roberts Sinto equipment and competitive OEM chemically bonded sand equipment (such as Tinker Omega, Palmer Manufacturing, Kloster, Omega Sinto, IMF, and Dependable/Redford).
Your scope covers the full spectrum of no-bake foundry equipment—including high-speed continuous single-axis and articulated sand mixers, resin/catalyst metering pump systems, compaction tables, rollover/draw units, mold handling conveyors, Flood Coat units, and attrition/thermal sand reclamation systems. This role requires a strong blend of precision fluid metering, heavy mechanical/hydraulic aptitude, PLC/controls diagnostic skill, and customer relationship management. We are looking for an independent problem-solver who can step into high-pressure foundry environments, execute major mixer and handling overhauls, diagnose complex binder dosing or mold-draw issues regardless of the nameplate, and minimize customer downtime.
General
- Full Machine Rebuilds, Retrofits & Modernizations: Lead and execute complete on-site tear-downs, mechanical and hydraulic overhauls, mixer trough and shaft rebuilds, blade/paddle reconfigurations, pump-cabinet retrofits, and PLC/HMI control upgrades on both Sinto and non-Sinto OEM no-bake equipment (including Tinker Omega, Palmer, and Kloster systems).
- Installation, Commissioning & Run-Off: Lead the on-site mechanical, hydraulic, pneumatic, and electrical setup, leveling, and run-off of new or rebuilt continuous mixers, compaction tables, rollover/draws, and sand reclamation systems, verifying that equipment meets factory specifications, strip times, and safety standards prior to handover.
- Mixer Calibration & Binder Metering Optimization: Perform sand throw and liquid calibration tests ("bucket and stopwatch" / mass-flow checks), tune resin, catalyst, and acid metering pumps (gear, peristaltic, and diaphragm pumps), calibrate flowmeters, and configure mixing blade angles and wear liners across various resin chemistries (furan, phenolic urethane/PUNB, ester-cured alkaline phenolic) to ensure consistent mold tensile strength and minimal binder waste.
- Multi-Brand Troubleshooting & Emergency Repair: Diagnose and resolve mechanical, hydraulic, pneumatic, and electrical issues across all makes and models of continuous mixers, pneumatic sand transporters, sand heaters/coolers, vibratory compaction tables, hydraulic rollover/draw machines, and attrition shakeout/reclamation units.
- Preventative Maintenance & Audits: Execute scheduled PM programs and comprehensive foundry equipment audits—inspecting mixer trough wear liners, tungsten-carbide mixing blades, shaft seals, pump heads, check valves, hydraulic proportional valves, and reclaimer screens to extend equipment life and scope replacement part or rebuild needs.
- Customer Training: Deliver hands-on training to foundry operators and maintenance teams covering safe mixer operation, daily trough cleaning and blade gap adjustments, binder calibration procedures, and routine wear-part replacement.
- Reporting & Documentation: Accurately document service visits, calibration data, machine audit findings, recommended spare/wear parts or rebuild scopes, and expense reports. Familiarity with digital field service tools and ERP systems (such as Infor SyteLine) is a plus.
- Remote Technical Support: Assist customers and internal After-Sales, Spare Parts, and Engineering teams with technical troubleshooting, cross-referencing competitive OEM components, and part identification when not traveling.
What We Want From You
Education & Experience:
- High School diploma or GED required; Associate degree or technical certification in Mechatronics, Industrial Maintenance, Electrical Technology, Fluid Power, or a related field preferred.
- No-Bake / Airset & Rebuild Experience: 4+ years of hands-on experience servicing and rebuilding chemically bonded sand equipment in iron, steel, or non-ferrous foundry environments. Direct experience maintaining, calibrating, and overhauling continuous sand mixers, mold handling loops, and sand reclamation systems across multiple OEM brands (Tinker Omega, Palmer, Roberts Sinto, Kloster, IMF, etc.) is strongly preferred.
- PLC, Controls & Fluid Power Experience: 4+ years of experience troubleshooting industrial electrical controls, 480V 3-phase power, VFDs, analog 4-20mA flow/temperature loops, hydraulic proportional/directional systems, and PLCs (Allen-Bradley/Rockwell or Siemens preferred), including adapting to legacy or third-party mixer control panels.
- Proven track record of successful, independent work travel.
Skills:
- Deep root-cause diagnostic capability across continuous mixing mechanics, precision chemical metering pumps, closed-loop flow control, heavy hydraulics (rollovers/manipulators), vibratory drives, and pneumatic dense-phase/dilute-phase sand transport—even when working on legacy or third-party equipment with limited documentation.
- Practical understanding of how machine variables (sand temperature, mixing retention time, blade pitch/wear, and pump pulsation) interact with no-bake binder chemistry to affect work time and strip time.
- Strong mechanical rebuilding and millwright skills, including mixer shaft/bearing replacement, trough liner refurbishment, hydraulic cylinder resealing/replacement, and conveyor alignment.
- Ability to read and interpret electrical schematics, hydraulic/pneumatic circuit diagrams, P&IDs for liquid binder systems, and mechanical assembly blueprints across various manufacturers.
- Strong communication skills with the ability to explain calibration drift, wear trends, rebuild vs. repair recommendations, and technical concepts clearly to foundry managers, metallurgists, and maintenance crews.
- High degree of self-motivation, safety awareness (including LOTO, chemical handling/PPE, rigging, and confined space protocols), and ability to work autonomously or lead small rebuild crews on customer sites.
Physical Demands & Work Environment
- Physical: Frequently required to stand, walk, climb ladders/platforms, bend, kneel, and use hands to handle tools and heavy machine components during tear-downs and rebuilds. Regularly required to lift and move up to 50 pounds unassisted. Specific vision abilities include close vision, depth perception, and focus adjustment.
- Environment: Regularly exposed to heavy foundry conditions, including moving mechanical parts, silica/specialty foundry sands, foundry binder chemicals (resins, catalysts, acids, and coatings), airborne dust/particles, confined or elevated workspaces, extremes of heat and cold, high noise levels, and risk of electrical shock.
- Travel: Ability to travel extensively (up to 75%) domestically and occasionally internationally, including multi-day or multi-week stays for major rebuild and installation projects and short-notice dispatches for emergency breakdowns. Must possess a valid driver’s license, a clean driving record, and a valid passport (or ability to obtain one).
