Industries we know

Food and beverage, packaging and plastics, water treatment and utilities, and military and aerospace — and what each one taught us.

Equipment varies less between industries than people expect. Constraints do not. A pump is a pump, but a pump in a dairy has to survive caustic washdown, and a pump in an aerospace shop has to come with paperwork.

These are the environments we have actually worked in.

Food and beverage

Processing, bottling, dairy and bakery. Washdown environments destroy bearings and seals that would last years anywhere else, sanitary requirements limit what you can put on a machine, and a stopped line is often product on the floor rather than just lost minutes.

Common work: motor and pump failures traced to water ingress, seal and packing problems, conveyor drives, and instrumentation that has drifted because it has been hosed down twice a shift for three years.

Packaging and plastics

Fillers, cappers, labellers, extrusion, injection moulding and converting. Highly sequenced machines where one sensor out of position stops everything downstream, and where frequent changeovers mean the equipment is constantly being adjusted by people under time pressure.

Common work: PNP and NPN sensor faults and their PLC inputs, servo and drive faults, pneumatic actuator problems, and heater and temperature control loops.

Water treatment and utilities

Pumps, blowers, chemical feed and the instrumentation that has to keep reading true because the readings are the process. Often remote or unmanned, which puts a premium on getting equipment onto a network where somebody can see it.

Common work: pump and blower diagnosis, magnetic and DP flow, level measurement, pH analysers, control valves, and monitoring so a drifting reading raises an alarm before it becomes a compliance problem.

Military and aerospace

Environments where doing it right is the requirement and documentation is part of the job, not an afterthought. Francisco's technical training began in the military, which is where the habit of working a procedure in order — rather than jumping to the likely answer — came from.

That discipline is why the diagnostic approach on every other job here looks the way it does: readings taken in sequence, recorded, and used to eliminate causes rather than confirm a hunch.

Also served

The four sectors above are where we have the deepest history. But the machinery underneath is the same across most of manufacturing — a 480 V motor does not know what it is making. We take work in all of these:

  • Metal fabrication and machining — presses, CNC machines, welding cells, material handling
  • Automotive and parts manufacturing — assembly lines, conveyors, robotic cells, press feeds
  • Aerospace suppliers and machine shops — precision equipment where documentation and traceability matter
  • Breweries, wineries and distilleries — pumps, chillers' driven equipment, bottling and kegging lines, CIP systems
  • Bottled water and beverage co-packing — fillers, cappers, labellers, palletisers
  • Pharmaceutical and nutraceutical — validated environments, tablet and capsule equipment, packaging lines
  • Cosmetics and personal care — mixing, filling and packaging, often with frequent changeovers
  • Chemical, coatings and adhesives — pumps, agitators, transfer systems, process instrumentation
  • Cannabis processing and extraction — extraction equipment, vacuum systems, chillers' driven components, packaging
  • Logistics and distribution centres — conveyor systems, sortation, dock equipment, palletisers, ASRS
  • Cold storage and refrigerated distribution — the material handling and motor control side; we do not service refrigeration circuits
  • Recycling and waste processing — shredders, balers, screens, conveyors, magnetic separators — hard-duty equipment that eats bearings
  • Paper, print and converting — web handling, tension control, rewinders, drives
  • Building materials, concrete and aggregate — crushers, screens, batch plants, dust collection
  • Agriculture and produce packing — washing, grading, sorting and packing lines, seasonal peak pressure
  • Marine, port and terminal equipment — we are minutes from the Long Beach and LA port complex; cranes, conveyors, hydraulics and drives

Not on this list?

Call anyway. The list is not meant to be exhaustive — what matters more is whether your machinery is on our capabilities list. If it turns and it has a motor on it, start with a phone call.
