Powder coating can be effective in an array of different market applications, but precision and expertise is required to ensure flawless results. Here are some of the top tips to help ensure successful outcomes, including why cleaning and operating in the right environment is essential.
Make cleanliness a priority
Experts recommend prioritising cleanliness to prevent contamination and poor results. This includes everything from ensuring pure air for the process and regularly cleaning jigs.
Specialists in powder coating and anodising, such as www.poeton.co.uk/surface-treatments/anodising/, may also recommend incorporating air-drying refrigeration in your premises to maintain dry, clean air.
Stop contamination
When powder coating and carrying out electrochemical processes such as anodising , it is vital to prevent contamination. Keep different types of powder and colours separately and thoroughly clean all systems after use. Look out for possible contamination from lubricants or insufficient pretreatment.
Recycle overspray
Invest in a system to recover powder and recycle this to optimise resource efficiency. Sieve the overspray and mix with new powder, up to a maximum of 30%.
Refine the curing process
Recognise that curing will require varying times depending on factors such as colour, shape, part size and substrate type. Oven temperature gradients also need to be taken into account to prevent uneven curing.
Ensure prime storage conditions
Powders must be stored in the correct conditions to ensure maximum quality. Storage life can be reduced if temperatures exceed 20°C, for example. Regularly rotating powders is also encouraged to maintain their freshness.
