How many parts can fit in a convection oven?
Carolina Filters has three convection ovens of various sizes. The number of parts depends on the size of the part and the number of parts received. We have several racking options to maximize loading and offer the best value for each convection oven process.
How is polymer removed from parts?
Polymer can be removed by physical, thermal, or solvent processes. The process selected depends on the polymer, the metallurgy of the parts, and the design and cleanliness requirements. We have a variety of each process to ensure the safest and most effective removal of a wide range of polymers.
How long does the parts cleaning process take?
Cleaning of any part is a unique process. Some parts require a few processes, while others require multiple runs in a variety of processes. We are generally able to return parts within 10-14 days.
How does Carolina Filters determine the best cleaning method for my equipment parts?
CFI determines the best cleaning method for any part based on the contaminant, the composition and structure of the part, and the required level of cleanliness. With this information, CFI’s team of engineers and cleaning professionals will develop a cleaning process that offers the combination of cleanliness, safety, and value to our customers.
What is the difference between DEECOM®, Thermal Cleaning & Solvent Cleaning?
DEECOM relies on a combination of hydrolysis and mechanical action to remove polymer from filters. As such, it is generally only effective on condensation polymers. DEECOM offers removal of polymer at a much lower temperature than traditional thermal cleaning, and also does not require the use of chemicals. From an environmental standpoint, DEECOM creates a much smaller carbon footprint and generates no waste that requires special disposal.
Traditional thermal cleaning is very effective in removal most polymers from various metal substrates. This method of cleaning does require careful management to ensure that the parts are not sensitive to the higher temperatures used and can tolerate repeated heating and cooling cycles. Our VacuClean ovens provide an excellent means to control temperature and reduce the risk of thermal excursions that may damage parts.
Solvent cleaning relies on various chemistries to break down polymer at a molecular level. Solvents require a tailored approach, as there is no universal solvent which will remove all polymers. Solvent cleaning is generally very mild in terms of temperature and offers a polymer removal option with minimal stress on the part.
