Chemical Milling & Etching Facilities

Mech-Chem designs, fabricates and installs systems and facilities for the chemical milling and etching of various metals, such as aluminum, titanium, molybdenum, nickel, and metal alloys. These systems/facilities are designed to meet each client's metal processing, pickling, and finishing operations. Process monitoring and control, chemical handling, and safety are an integral part of each system/facility built by our company.

Mech-Chem provides the engineering, design, construction, and start-up of the process, equipment,Complete chemical process line design and installation instrumentation, controls, piping systems, and panels and electrical wiring required for Chemical Milling and Etching Systems.

The chemical milling and acid etching systems are appropriately designed and installed to handle the corrosive environment created by the acids and chemicals, as well as accommodating the production, process, operating and product quality requirements of the client.

These complete chemical milling and acid etching systems are constructed and started up as turnkey operations. These systems are comprised of the following tanks, equipment, secondary containment, instrumentation, and controls:

  • Chemical Milling Tanks
  • Acid Pickling/Etching Tanks
  • Rinse Water Tanks
  • Ventilation Hoods/Ducts/Fittings (Polypro/PVC/FRP)
  • Fume Scrubber and Blower
  • Air Make-up System
  • Heating/Cooling Systems
  • Acid/Caustic Feed Systems
  • Wastewater Treatment Systems
  • Hoists and Monorails
  • Panel (PLC/Motor Starters)
  • Safety Showers
  • Secondary Containment

The chemical milling and acid etching systems are equipped with the following piping, electrical, and utilities, which are appropriately designed and installed to accommodate the hazardous chemical and process requirements for operating the systems:

  • Acid/Caustic Piping
  • Acid Heating/Cooling Loop Piping
  • Heating Solution Piping
  • Cooling Solution Piping
  • Compressed Air Piping
  • Process Water Piping
  • Wastewater Piping
  • Potable Water Piping
  • Power Wiring
  • Electrical Wiring (NEMA 4X)
  • Process Safety and Alarm Systems

The systems have full PLC automation to monitor and control the operation of the system including heating and cooling of the acid solution, operation of the fume scrubber, and wastewater treatment. The PLC with GUI (Graphic User Interface) touchscreen provides pull down screens for each operation, process safety and alarms, and fail-safe system shutdown in case of an emergency. In addition, the PLC can interface with a computer for remote operation of the system and storage of data for quality control and documentation.

Mech-Chem also provides all the detailed design drawings and specifications for the tanks, equipment, secondary containment, instrumentation, and specifications and the detailed mechanical and electrical design drawings and specifications for the piping, utilities and controls.

Each system comes with a operating and maintenance manual complete with operating procedures, spare parts lists, process drawings, and manuals for each piece of equipment, instrumentation, and component used in the system.
