Metal Finishing and
Pollution Control
Mid-Western Processes, Inc. is involved in virtually all
aspects of metal finishing lines, including anodizing, phosphating, pickling,
electrocoat paint, resource recovery, electroplating, continuous strip and tube plating,
plating on plastics and chemical processing.
There are currently over two hundred Mid-Western hoists in operation.
The systems use barrels,
baskets, and racks. Hoist load capacities range from a few hundred pounds to over 15,000
pounds, and production capabilities over 100,000 pounds per hour.
Our effluent treatment systems are modularized for efficient
installation, and range from small batch treatment to fully automated continuous systems
handling flows in excess of 200 gallons per minute. Chemical and physical treatment
systems can include (as required): hexavalent chromium reduction, cyanide oxidation,
neutralization, precipitation, clarification, sludge de-watering, evaporative recovery,
and ion exchange. Our filter presses range in capacity from 0.5 ft3 to 50 ft3.
Mid-Western Processes, Inc. designs and manufacturers systems to handle
a variety of very difficult part handling situations including
load
and unload systems. Other products are: hydrostatic level control systems that are
extremely accurate and unaffected by oils, foam and solids; control panels; the
"Barrel-Aire" connector system, which allows the running of rotating barrels and
racks in the same process line. The unit functions automatically and eliminates any
electrical hazards.
Mid-Western Processes, Inc. makes extensive use of programmable
controllers on all systems we design and sell. We can offer a variety of computer-aided
management systems to provide real time man-machine interfaces and production or process
data acquisition and logging.

of Mid-Western Processes, Inc's metal finishing production line capabilities. This
includes the areas where we have expertise in designing and building complete or partial
solutions to the various industrial metal finishing industries.

The field of electroplating or metal finishing today is moving away from
large manufacturing operations and into smaller job shops. With increasingly strict
regulations governing metals in wastewater and increasing costs for disposal of
metal-contaminated waste, many metal finishers find that implementing pollution prevention
measures such as filtering or treating process water to reduce or eliminate metal
contamination and allow water reuse is the best option, both environmentally and
economically. Plating processes in this sector include chrome, bright and electroless
nickel, zinc, copper, tin, conversion coatings, and more. Information is included on
regulations, permits, trade associations, and available and emerging technologies.
Our production crews know the Electroplating industry.
We understand basic chemistry, including atomic structure, elements,
molecules, pH, acids, bases, vital equations, neutralization,
oxidation-reduction, reaction kinetics, analysis, titration, atomic
weight, critical calculations associated with process solutions.
We also:
Understand the relationship of electricity and the typical
equations involved in surface finishing as they concern rectification, electrical
connections, resistance, voltage, amperage, measuring meters, and special electrical
equipment;
Have a basic knowledge of electrochemistry (potentials, galvanic
series, electromotive force series, plating cell, current distribution, over-voltage,
polarization, and calculations critical to thickness and current density determination;
Know the importance of each step in the finishing process
(cleaning, pickling, rinsing and drying); understand effective rinsing techniques and
water conservation;
Understand the major deposition systems and applications for each:
acid zinc chloride, non-cyanide zinc and cyanide zinc plating solutions, cyanide and
bright acid copper, nickel plating, decorative and hard chromium, electroless deposition,
and precious metalsgold, silver, palladium, etc.
Know how to test and evaluate electrodeposits;
Be able to select deposit capabilities with respect to the needs of
the application and consider alternative cost-effective and functional deposits;
Understand the principles of anodizing aluminum processes,
including sealing and evaluation of the final coating;
Be able to perform process controls such as Hull Cell testing,
carbon treatment, and filtration;
Know when and how to use chromate conversion coatings and
phosphating;
Understand corrosion mechanisms and preventive steps;
Be familiar with the technology of cyanide and chromate waste
treatment, as well as specialized handling and disposal of the resultant sludge;
Know safe and responsible handling of chemicals; the use of proper
protective clothing and/or equipment; and emergency first-aid instructions;
Understand various metallurgical processes (such as stamping,
casting, forging, rolling, die casting, metal drawing, extrusions, powder metallurgy, hot-
or cold-working, and case hardening of metals) and their effect on the surface finishing
process;
Understand the basic theory of alloy plating and various alloy
plating processes, including zinc-nickel and zinc-cobalt (acid and alkaline), tin-zinc,
zinc-iron, copper-zinc alloys (brass) and other commercial alloys;
Mid-Western Processes, Inc. has been involved in Metal Finishing for over
25 years. During this time we have gained extensive practical experience in the design,
construction and function of Metal Finishing Plants, employed both in our own sub-contract
operation and in our many customers installations which we built for them. We can
offer equipment ranging from compact manually operated plant up to fully automatic,
computer controlled multi-station installations for a wide range of applications
including:
Cleaning * Pickling * Electropolishing *Electroplating *Anodising
*Phosphating * Effluent Treatment.

The size of the installation and complexity of operating cycle present no
obstacle to our experienced design team. Turnkey projects are our specialty and can
incorporate fully automatic waste water treatment equipment and fume extraction systems
when required.
DESIGN
Employing the latest CAD techniques, MWP is able to design equipment to satisfy a whole
range of plating specifications. Plant layout and foundation drawings, together with
details of the location of services required (electricity, water, tanks, hoists,
conveyors, etc.) are produced and submitted to the client for discussion and
approval.
MANUFACTURE
On completion of the design work, detailed drawings are finalized and schedules produced
to plan and monitor the progress of the subsequent manufacturing stages. On automatic
systems we incorporate the latest computer control technology allowing a computer
interface with a simple step sequence programming language that is simple for your
operators to understand.
INSTALLATION & COMMISSIONING
Complex turnkey plants are best installed by our experienced plant engineers. These
complete production plants are normally constructed in modules to reduce installation
times and are fully assembled for a dry run trial prior to delivery to the
customers works.
Commissioning follows installation and operatives and your engineers become fully familiar
with the operation of the equipment and the relevant maintenance procedures.
AFTER SALES SERVICE
Commissioning of the plant is not the end of the story as far as Mid-Western Processes,
Inc. is concerned. We have a vested interest in ensuring that you are fully satisfied with
the Electroplating plant we have supplied.

Send us your CAD drawings and MWP engineers
can begin work immediately to find the solutions or interface new equipment into your
existing Electroplating production lines.

Our experience in making production lines for the Electroplating
industry does have some real perks for new clients.
Speed: By performing the
tasks in-house - conceptual design, modeling, schematic development, board layout,
prototyping, qualification testing, manufacturing and functional test - our project
managers have control over the entire process and will get you to market quicker.
