Motorcycle Helmet Coating Line

Motorcycle helmet is plastic or fiber based production which requires multiple painting treatment for user acceptance. High quality coating line solution is the base for high quality helmet production. We’re going to introduce the different technologies from our company and guide on how to choose the proper line for your production.

Helmet Coating Line Process Flow

The helmet coating line general process low is designed like this:

cleaning -> loading -> pre-heating -> electrostatic de-dust -> color coating spray -> flatting -> varnish spray -> flatting -> curing -> unloading -> QC check and reparing -> final products

Before loading to coating line, there’re multiple crucial workflows from pre-treatment. The purpose is to get smooth surface by repairing some bad points by sanding. then we need to spray a sticky base coat on it to make sure color coatings can be well coated. That’s why there’s no base coat from above workflow, because it’s already done from pre-treatment.

• Pre-treatment: The process involves degreasing and cleaning, water rinsing, surface conditioning, phosphating, pure water rinsing, and drying to prepare the helmet surface for painting, ensuring it is in a suitable state for coating.
• Spray Painting:The prepared paint is evenly applied to the helmet surface using an automatic spraying machine and spray gun, forming a uniform coating. This step requires strict control of spraying parameters to ensure coating quality.
• Curing:The painted helmets are then sent into a curing oven for curing treatment. This allows the coating to fully cure and achieve the required performance characteristics, such as hardness and wear resistance.

Motorcycle Helmet Coating Line Core Devices

Automatic Spray Painting Machine – This is one of the core pieces of equipment in the spray painting line, capable of precisely controlling the amount, speed, and range of paint application. For workpieces with complex shapes like helmets, the automatic spray painting machine can achieve efficient and stable spraying operations. It can be programmed according to the shape and size of the helmet to achieve automated spraying, ensuring a uniform coating.

Spray Gun – Used in conjunction with the automatic spray painting machine, the appropriate type of spray gun is selected based on different paints and spraying requirements, such as air spray guns and electrostatic spray guns. Electrostatic spray guns improve paint utilization and coating uniformity, making them particularly suitable for products like helmets that require high coating quality, allowing the paint to adhere better to the helmet surface.

Paint Supply System – This includes paint tanks, paint pumps, filters, etc., used to uniformly deliver the paint to the spray gun. The paint pump provides stable pressure, and the filter removes impurities from the paint, ensuring spraying quality and preventing impurities from affecting the smoothness and adhesion of the coating.

Spray Booth – Provides a relatively enclosed and clean environment for spraying, preventing paint from splashing into the surrounding environment, and collecting excess paint for recycling. The spray booth is generally equipped with a ventilation system to promptly remove harmful gases and dust generated during the spraying process, ensuring the health of operators and the cleanliness of the spraying environment.

Baking Oven – Based on the type of paint used, the appropriate baking temperature and time are selected to ensure the coating is fully cured. For paints commonly used on helmets, infrared heating or hot air circulation heating is generally used to ensure the helmet is heated evenly and the coating quality is guaranteed. For example, some high-performance paints require specific baking conditions to achieve optimal performance.
