Chemistry

Aqueous Cleaner Selection Criteria

This one-page list of questions offers considerations for selecting an aqueous cleaner.

Role of pH in Cleaning Chemicals

Learn about when to use which type of chemical cleaner for an application, and how understanding the pH scale in this situation is beneficial.

Heat’s Impact of Parts Cleaning

Thermal dynamics is important for assisting in the cleaning of a part. Adding heat or energy influences the cleaning process through its impact on chemistry, the water within the washer and its effect on drying.

Taking Care of an Industrial Parts Washer

Proper parts washer maintenance is key to a long life for the system and reliable parts washing.

Rinsing and Drying Cycles are Just as Critical as Cleaning Cycles

In addition to the actual cleaning technology, a critical cleaning process must also use suitable chemicals to ensure high-quality rinsing and drying processes.

The Right Solvent Creates the Cleanest Parts

Cox Manufacturing Co. has worked with Kyzen Corp. since it implemented its vacuum vapor degreaser to find just the right chemical solvent to clean its customers’ parts to their specifications and beyond.

VIDEO: Vapor Degreasing Process Uses TCE REplacement to Eliminate Hazardous Waste

A solid relationship with a solvent manufacturer has aided Electro-Spec Inc. with the implementation of a trichloroethylene replacement material in its vacuum degreasing unit to clean a customer’s micromachined parts more efficiently.  

Future-Proofing a Parts Cleaning Process with Modified Alchols

Modified alcohols can be reliable replacements for the solvents currently under scrutiny by the EPA. The non-halogenated solvents have good drying qualities, are very stable and have low surface tension.

Cleaning Equipment

General Guidelines for Maintaining Alkaline Cleaning Tanks

This is a detailed description from Brulin of five common alkaline bath tests.

Choosing the Right Aqueous Cleaning Operation

For most machining processes, water-based solutions can be applied using tailored technologies for specific applications.

The Function of a Vacuum Vapor Degreaser

Vacuum vapor degreasing is among the fastest growing parts cleaning technology because of all the benefits the process offers.

Automatically Deburr, Clean Parts in One System

Palletized parts are transferred from a five-axis, high pressure waterjet station to a cleaning station via linear motor to enable, fast, automated finishing.

Processes

Nitric vs. Citric Acid Passivation

While both nitric and citric acid passivation effectively passivate stainless steel and other alloys, the one you select depends on the alloy itself and the benefits you most value

How to Choose and Set Up a Manufacturing Cleaning Process

Choosing the right cleaning process for an application takes thought and understanding. Knowing the basics of cleaning, the costs associated with it, as well as how to test, validate and inspect parts that are cleaned is critical. Teamwork and communication are also important in getting the job done efficiently.

‘Soft’ Metal Staining, Post Cleaning

In the push to go green, many fabricators are switching to water emulsifiable metal working fluids. The formulators of these lubes use different additives, for the lube to perform properly.

Corrosion Prevention Procedures for Metal Parts

There are many ways to prevent corrosion, including modifying the atmosphere by dehumidification, nitrogen purge, evacuation, and creating a barrier on the metal surface to prevent the permeation of moisture.

Filtering Cleaners, “Cleaning the Cleaner” Questions and Answers

Learn about the variety of filters for removing particulates from a cleaning fluid, how to determine cleaning fluid life and more.

How to Reduce Steps Required in Nonferrous Surface Finishing

The finishing of parts made from various copper and aluminum alloys traditionally require many distinct and separate process steps. Hubbard-Hall’s Mike Valenti explains how both come with their own unique needs.

Alternatives to Air Sparging Make Better Choices for Tank Agitation

A modest investment in cleaning tank modification to eliminate air sparging can provide significant savings in improved part processing, saving both time and money.

Improve Energy Savings with Vector Kinematics

The rocking, rotational nozzle movement performed by vector kinematics spray cleaning technology combined with temperature and cleaning additives provides an effective, fast and economical parts cleaning process. 

Trends in Parts Cleaning
The latest cleaning trends point toward environmentally friendly ways to clean effectively, involving the replacement of harmful chemical solvents within a cleaning process or switching to a mostly aqueous method.

New Cleaning Methods for Alternative Manufacturing Processes

Tyler Wheeler, product line manager at Ecoclean Group, covered the current manufacturing trends and how cleaning technologies are evolving to keep up with the cleaning demands of these trends.

Video: The Advantages of CNC in a Cleaning/Deburring Process

This on-demand webinar from Sugino Corp. offers information on CNC waterjet for cleaning and deburring parts, pressure pumps and nozzle options for the system as well as how to add value to the process.

Measurement

Particle Analysis Evolves with Specifications

Cleanliness analysis equipment has become more advanced as testing and reporting particle contamination levels have become more critical.

Computerized Measurement of Contact Angles

The primary purpose of this paper is to demonstrate that contact angles of sessile drops can be accurately measured using very low-cost equipment in conjunction with open-access computer programs.

A ‘Microscopic’ Look at ISO 16232 Standard Analysis

This article gives three key points that should be confirmed with a microscope support team or within microscope software to ensure that proper settings are in place to detect, measure and categorize most particles for automotive manufacturing. 

Dealing with Failed Cleanliness Limits

Markus Rossler, vice president, Glaeser Inc., offers guidelines for ensuring parts cleaning standards.

Regulatory Updates

How EPA Decision Might Affect Surface Preparation

Last year, the EPA determined that four degreasing solvents used in parts cleaning pose “unreasonable risks” to workers. By the end of 2022, there should be new rules outlining restrictions on how the solvents can be used. Solvent bans are possible. What should surface finishing companies do?
