The Difficulty of Automatic Trace Spraying

Tutorial

Automatic trace spraying means the spray gun will spray on loaded objects while they're moving forward on a conveyor system. The painting machine or robot will follow the conveyor speed and complete the spraying before objects move out it's effective working area. When everything setup well, it seems pretty easy. However, things are not always as expected due to various conditions. When we configure a robotic spray painting system, we always need to automate the setup as much as possible regardless the spraying method. But it's not always so easy to make it working as design principle due to technical limitation or the onsite operator skills. In this article we will briefly explain the concept and required technology in order to configure a full automatic trace spraying system by industrial…

VOCs and Control in Automotive Coating Industry

Tutorial

In the coating process, VOCs are mainly produced in the spraying and drying process of the middle coat and top coat over plastic parts finishing(sealing and spraying due to relatively small content of VOCs). The organic waste gas produced by painting has the characteristics of large air volume and medium to low concentration. 1)Paint spray booth: The main harmful component from paint booth exhausting is the organic solvent volatilized during the painting process. The spray booth exhaust volume is large but the total concentration of organic matter is low, generally below 100mg/m3. In addition, the exhaust from paint spray booths often contains a small amount of paint mist that has not been fully treated. Especially in the dry paint filter spray booth, there are more paint mist exhausted. 2)Drying chamber:…

Why Flame Treatment in Paint Spraying?

Tutorial

Flame treatment principle Flame treatment is a widely used process for surface modification of substrates such as plastics, glass and metal foils to improve their adhesion to liquids such as inks, paints, binders and coatings. Plastics used for flamming are thermoplastics and thermosets. When heated, thermoplastics will gradually soften and melt with the increase of temperature, and will become hard after cooling.At the same time, this process is reversible. We generally use surface tension or surface energy to measure the ability of the substrate to adsorb liquids, and if the substrate surface energy is at a high level, the liquid will become more wetted on its surface and have good ductility. Making the liquid more wetted on the substrate is the basis for the substrate to adsorb the liquid. If…

Paint Shop Safety Planning

Tutorial

Spray painting machine is widely used in almost all industries for it's flexible application. Safety is considered more and more due to uprising issues caused by various reasons. Beside furthermore training to improve the safety concept and experience sharing, we also need to avoid potential factors from the initial start such as machine designing and production. Here we have a safety list including both mechanical and electric tactic. Mechanical construction Most part of painting machine construction is mechanical. Although the basic logic and concept is pretty simple, the final presentation can can easily tell the manufacturer's skill and management level. Beside the general functionality, we have to pay attention to each small piece considerring safety such as no sharp edge and corner protection etc. For example after a steel plate…

Full Automatic or Semi Automatic Painting System?

Tutorial

When considerring a painting system for our business, we have numorous selections and could be misguided if we can't indepth evaluate our tailored needs. Ideally, we should make full use of the machine to be a powerful backend of our business improvement. If we select a wrong machine, it's not just about monetary but also a bad affect to our business development. Thus a smart decision is not a single purchase but a tactic to future. How to choose the most suitable painting machine? Regardless the various choice, there're basically two options - full automatic and semi automatic. The only difference is how the process being handled through various mechanical devices such as robot or penumatic guns etc. Following we will indepth introduce the two options and guide how to…

Water Base Paint System Configuration

Tutorial

Water base paint is popular choice for coating industry, especially for automotive area where eco friendly is deeply concerned. From marketing report, over half traditional paint production are looking for water base solutions and doing A/B tests over different objects and various working environments. However, water base paint is a big difference to solvent solution for it's chemical structure, and it also has very different requirements to it's application system. Following we're going to point out few crucial parts we need pay attention to when configuring a water base paint spraying system. Spray booth A very basic device for any paint application, but water base paint have different requirements to it. The initial point is the booth material choice which has to be stainless steel (SUS304 suggested) to avoid rust…

3 Defective Phenomenons and Fix of Paint Spraying

Tutorial

Spray painting is logically a pretty easy job which seems to be hassle free for any people. As it's basically to trigger spray gun to send out liquid paint by pumping. However, in real working condition we always have to hire a professional technician at fruitful costs for guaranteed output painting quality. Why is this and what makes this seem-to-simple task costly? Paint spraying principle The basic logic of paint spraying is to atomize liquid paint then apply to object surface smoothly. The necessary tools include a spray gun, pressurized pot or pneumatic pump for paint supply and a compressor. Spray gun is moving above object surface with specific angles and speed to complete the finishing process. Spraying defective phenomenons Common problematic phenomenons such as following: Color difference - the…

Robot Protective Clothing Cover

Tutorial

Robot protective clothing covers are made to prevent damage and high maintenance costs due to contact with dust, paint, oil, heat, molten metal, as well as metal scrapings and liquids during operation in various working environments. Robot clothing and robot protective covers have been used to prevent component failure, allow robots to operate in a big range of conditions, and extend the operational life of the robots. In general, robot protective clothing covers are designed by the following scenes: 1- Heat Protection Robot Cover This kind robot is mainly used in welding, especially in casting industry where is high temperature operation. Thus, robot cover must be heat resistance to prevent heat destroy to robot components. This kind of cover is mainly produced by tinfoil and fiber material for flexible and…

Components for Painting Robot Construction

Painting robot, Tutorial

Painting robot is advanced choice for modern paint shop construction. However the setups vary a lot from different service provider. Not only about it's arrangement over different components but also the choice of some crucial parts for actual paint application. A good and reliable configuration will support the operation at extremely high efficiency and reduce lots of maintenance problems. In this artice we will list out all the required components for a painting robot configuration which is based the actual experience over multiple painting systems deployment. All components are world class production with seamless connection to each part. Of course, the robot itself is most crucial part as everything else will be arranged by its technical specifications and the final performance all depends the robot construction. A good robot provides…

Paintshop Waste Air Treatment

Tutorial

Paintshop will make a big amount of waste air during operation. Based the current paint spraying technologies, the maximum paint application rate is about 60%. That means at least 40% paint will be extracted. If the paint booth provides up to 90% filtration capacity and save the solid particles inside booth tank, rest 10% is still hazard if we blow into atmosphere directly. Especially when the factory is close to a residential area, there're very strict extraction standards. Thus a proper treatmen solution is required for any paint shop construction. Waste paint air treatment or filtration is a complex system based the construction standards. Generally there're following stages for a complete clean filtration: water filtration - carbon filtration - VOC treatment - flame treatment. Water filtration - The primary and…
