Security Door Spray Coating Line

Security door or safe door coating line is applied through overhead hang conveyor which includes a spray booth and curing furnace. For a complete setup its also configured with a pretreatment system to make each door clean enough before spray coating. A safe door coating line can be setup in various ways based the finishing requirements and the type of coating we’re going to use. Generally we make it liquid and powder coating as per setup standards.

Security doors are normally made by steels or stainless steel, thus high quality painting treatment is important for either rust-proof or fruitful coloring purpose. For both liquid and powder coating we highly suggest electrostatic way to save paint consumption and less waste treatment. Electrostatic coating is high efficient and friendly choice for any metal product without special pretreatment required.

Liquid painting

Painting is well known for its super smooth and shinning color. For liquid painting we highly suggest electrostatic solution such as DISK or electrostatic turbo bell via reciprocator. When selecting liquid painting, we normally configure a water curtain spray booth to catch over spray and maintain a clean operation space. Considering we need to paint both front and back side, an extra paint booth will be needed to work concurrently. From entrance and exit we will make a manual station to check if everywhere painted properly, a lightly hand spray needed just in case.

Powder coating

Powder coating is the ideal choice for security door production. The electrostatic plastic powder coating provide extra paint thickness to deal with daily use much better. Powder coating also provide some special treatment such as wood grain or other special type surface. Considering coating consumption, powder coating can be recycled to re-use and make it almost zero waste.

Full process of security door powder coating is: Pre-treatment(rust removal, rinsing & phosphating) -> drying -> painting /powder coating -> curing -> cooling & unload
