Metal finishing and manufacturing

Build a controlled cleaning and pretreatment process.

Coordinate parts washing, degreasing, surface preparation, passivation, phosphate and temporary corrosion protection around the part, soil and downstream finishing requirement.

A cleaner part is only the beginning

Production metal finishing depends on what happens before and after cleaning. eChem evaluates the full sequence so soil removal, rinsing and surface condition support the next operation.

Production soils and heavy loading

Address coolants, oils, chips, polishing compounds and shop soils with equipment sized for realistic loading.

Surface preparation and conversion chemistry

Control passivation, phosphate or other pretreatment chemistry around the alloy and finishing specification.

Rinsing, drying and corrosion control

Prevent carryover, water spotting and flash rust through rinse design, drying and compatible temporary protection.

Equipment and chemistry pathways

Start with the part size, soil, handling and required surface condition. These equipment and chemistry families cover common manufacturing processes.

Application evaluation

Define the required surface condition.

The correct process starts with a measurable outcome for the next step—inspection, coating, bonding, assembly, heat treatment or storage—and then works backward through cleaning, rinsing and drying.

Alloy, part size, geometry and batch weight
Coolant, oil, chips, scale and polishing media
Required cleanliness or conversion-coating specification
Current handling and target throughput
Water quality, rinse stages and discharge constraints
Drying, flash-rust risk and downstream operation

Improve your metal-cleaning and finishing process

Share the part, soil, production rate and required surface condition. eChem will help identify the best testing and equipment path.
