Automatic paint spraying is not a bare spray gun but multiple crucial devices such as paint pump and control system. Paint supply device is direct connection with spray gun, thus a correct selection is very important for smooth operation. Most paint spraying is supported by air based technologies so there're two options of paint supply - diaphragm pump and pressure pot. So which one is better? In following content we will briefly introduce the two options and compare side by side from operator sight. Diaphragm pump The diaphragm pump definition comes under the classification of positive displacement pumps that utilize the grouping of the reciprocating operation of thermoplastic, rubber and Teflon diaphragm. The flowrates of these devices will not fluctuate much with that of discharge pressure which means the pump…

Chain conveyorised painting line system is widely used for it's high efficiency and ease of operation. Especially for mass production requirements, chain conveyor system transfer products automatically through each treatment station from start to end. No manual touch during this process for guaranteed quality. Chain conveyor is a crucial component in this painting line system but not considered seriously most of the time. Here in following section we will provide in-depth guidance how to configure a suitable conveyor system to work well with production requirements in long run. Genearl setup principle Chain conveyor is a basic but very technical design component of painting line. The mechanical structure has to follow existing space design and fulfill paint technical requirements. Thus a good design will provide a tight structure to make full…

In coating industry, there're various ways of paint application and each solution has its unique advantages. In order to choose a suitable method, we need to check carefully on multiple specifications such as object design, dimensions and production requirements etc. In this article we will compare two of the most popular solutions - fixed gun spraying on chain spindle system and robotic spraying machine. We will start from technical review, ease of use and production efficiency and give our followers an indepth guidance. Fixed gun spraying brief review As the name says, spray gun is fixed in paint booth. In production, we need to adjust spray gun angles and positions so paint can by sprayed on objects properly. Products are loaded on spindles by chain conveyor system. When passing through…

Robotic painting system is widely used for modern paint shop construction, painting robot is primary choice for its flexible programming in handling different products paint spraying. But what's actually included for a painting robot system? It's not just a single robot arm but a system with multiple devices. In this article, we provide indepth guides about a painting robot system configuration and how to customize each device in right way. Genearally, a painting robot system is composed by following: robot arm, robot installation platform, turner table, spray booth, paint pump and spray gun. Robot Arm The basic but core device. The choice of robot arm mainly on two points - payload and reach limit. Payload is determined by the type of spray gun we will use, the general capacity of…

Electrostatic dust cleaning is a crucial stage for spray painting system in order to receive high quality surface finishing. Dusts on object is mainly by electrostatic absorption during production or transportation. Dust cleaning unit is to generate ionized air to neutralize static current on object and remove dusts. Following we'll briefly introduce how electrostatic dust cleaning works and the equipment configuration standards. Electrostatic dust cleaning is one of the most popular solutions for cleaning treatment. Static nozzle is connected with power supply (220V or 110V /input voltage 4.6KV), then connected to the ion needle through high-voltage cable, this nozzle will then generate a strong electric field, through the tip of the high-voltage corona discharge of air molecules ionized, ion needle tip to produce a large number of positive and negative…

Spray gun is a precise tool for paint application. But it's not a standard piece, so we need to select a right model for specific paint spraying. After a long history of solvent base paint development, water base paint is leading the industry for it's environment friendly and safety to health advantages. Here we provide basic guidance of water base paint spray gun Water base paint spray gun is mainly offered as low pressure model(inlet air pressure under 1.8Bar) with less air flow and less pressure for high grade paint atomizing. Because of reduced spraying pressure, less paint bounce back is expected for high quality painting control, especially for some conditions such as reparing work. Water base paint spray gun advantages quick view suitable for water base and solvent base…

Electrostatic turbo bell is the best choice for high quality paint spraying. Either for paint thickness control or surface evenness, turbo bell is unbeatable choice comparing to any other spray gun model. How does an electrostatic turbo bell work and how it's outstanding from the industry? In this article we'll briefly introduce from it's turbo structure design to final application and see why it's primary choice for high end application. Electrostatic Turbo Bell Brief View Being a high end choice spray gun tool, electrostatic turbo bell provides a special design for paint atomizing (up to 60,000 rpm bell rotation speed). The atomized paint is unlike traditional liquid flow but fog like tiny particles as a result of the high speed spinning. Thus paint atomizing grade is extremely high comparing to…

Sublimation coating is a widely used technology for heat transfer on decoration items such as ceramic mug. But how to apply this coating properly is a technical tatctic which is not workable by home purpose. Here we mainly talk about the mass operation for industrial production line. What's sublimation coating? Sublimation coating is clear, paint-like coatings that can be applied to virtually any surface, making that surface into a sublimatable substrate. In this process, it allows an image to be transferred to any type of product or surface that has been covered with the coating. Sublimation coatings are applied using aerosol spray, which affords a greater control over the amount applied. Materials as diverse as wood, metal and glass can be coated to allow images to adhere to them and…

Paint shop is widely setup for various products surface coating treatment. But if you pick up any system to compare you would see there're not two complete same setups even for the same product painting. It brings a lot of problems for people when trying to purchase a machine. Especially at the early stage, suppliers always have to ask us a lot of questions in order to receive a quotation, but sometimes we do not even have answers to those questions. Why it's not a standard configuration so we can select directly? Well, this seems weird. But it's truely the condition of this industry. To see why it is, we will briefly bug from the following categories and offer quick guidance how to get start professionally. Workshop Space It's for…

Woodware industry is so close to everybody due to its 100% availability in every home and office. Thus the woodware painting is crucial to meet with various standards. In following, we will briefly introduce the main painting solutions used for different types wooden furnitures such as wood board, wooden doors and chair etc. Roller Coating Widely used technology for wood board coating. It's workable for solvent and water base paint on flat conveyor system. Roller is attached with paint then pressed on board. Conveyor system will take the board to pass through drying tunnel directly to get final coated piece. The painting station is pretty fast thus the drying tunnel is relatively long comparing to other painting system configuration. It's normally setup for mass production demands. As we see, roller…
