The field of industrial parts cleaning represents a crucial yet often overlooked component of manufacturing and maintenance operations. Effective cleaning processes ensure product quality, extend equipment lifespan, reduce downtime, and contribute to workplace safety. This comprehensive guide explores the multifaceted world of industrial parts cleaning, from fundamental principles to cutting-edge technologies.
The landscape of industrial cleaning has evolved dramatically in recent decades, driven by increasingly stringent quality requirements, environmental regulations, and economic pressures. What was once considered adequate cleaning may no longer meet today’s standards, particularly in high-precision industries like electronics, aerospace, medical device manufacturing, and automotive production.
This book aims to provide professionals with a thorough understanding of cleaning methods, equipment selection, process optimization, and practical implementation strategies. Whether you’re a process engineer, maintenance manager, quality control specialist, or operations director, the knowledge contained in these pages will help you make informed decisions about cleaning processes that balance effectiveness, environmental responsibility, cost efficiency, and regulatory compliance.
This book is designed to provide automotive and automobile, maritime, marine and ship building, aviation and aerospace, oil & gas and other manufacturers with basic information about industrial parts cleaning technologies. This information should help provide companies that are considering replacing an existing cleaning technology with a new method with some direction for their decision making. The information in this book is not solely adequate for making a decision to alter an existing cleaning process. Additional information from technical assistance providers, equipment vendors, and engineering consultants should be used in addition to the information provided here.
WHY CHANGE
Solvent cleaning operations are wasteful. While solvent evaporation provides advantages when dry parts are required, it also accounts for significant losses of solvent that could. be used for cleaning other parts. Open top vapor greasers commonly lose 60% of their solvent through evaporation. Dip tank, spray, and wipe-down cleaning all lose large amounts, or all, of the solvent through evaporation. Measure the cost of this wasted solvent and then ask yourself if there isn’t a better way to clean.
RCRA, SARA, TRI, CAA, OSHA, CERCLA, are familiar acronyms that highlight the regulatory burden from solvent cleaning. Solvent cleaning operations produce hazardous waste and/or emissions that require extensive regulatory reporting, affect worker health and safety, and can incur long term liability to your company. Think of the fime and effort that goes into complying with hazardous waste regulations and the ask yourself if there isn’t a better way to clean.
EVALUATING CLEANING REQUIREMENTS
Changing a cleaning process to a new technology requires careful planning to avoid risk to the manufacturing process and product. A stepwise approach to evaluating your existing cleaning operation and choosing a new method will help to ensure success.
l) Determine if you need to be cleaning the part in question. Can multiple cleaning steps be combined? Can the soils on the part be eliminated to reduce the need for cleaning? Can soils be carried through several manufacturing steps before cleaning?
- Know exactly how clean the part needs to be for the next manufacturing step. Are you over-cleaning? Establish cleaning standards that can be verified by testing the part.
- Understand cleaning fundamentals. What is the nature of the soils on your parts?
