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…

Paint drying is to transfer wet paint to solid state. Paint or coating drying is a crucial process after precise spraying. If the paint is not properly cured in right condition, the paint layer can not stick to object or even lead to pollution to other components after assembled. In this article we provide general guides how to select a suitable drying device and introduce the current popular curing technologies. As we know, different paints are produced by different chemicals, some are solvent based and some are water based. Thus, the different rate components result in different drying conditions. Some paints can be fast dry in room temperature without any device, but some paints require extremely high temperature in a precise furnace. Generally, paints are categorized in liquid and powder…

Definition of coating Coating is a kind of liquid or powder substance, which can be uniformly covered and attached to object surface to form a continuous and dense coating layer. After dried and cured by natural or thermal condition then a solid coating film will be formed. Coating layer has protection, decoration or other special functions to object. Although the definitions of coating are slightly different in different documents, they all emphasize two characteristics of coating - it contain film-forming properties and has important impact on the substrate. Classification of film-forming substances Generally, the composition of paint is divided into three types: main film-forming substances, secondary film-forming substances, and auxiliary film-forming substances. 1. Main film-forming substances Main film-forming substance refers to the polymer material which is the basic substance in…

Our robotic painting machine is quite flexible configuration to meet with customer various paint spraying requirements. For quick understanding how we can setup the machine, we post the following for new user on how to get started. Firstly we must know what kind product to paint. For example the physical dimensions and its painting requirement(full painting or partial painting on specific area). Once we leant the actual product and it's spraying needs, we can then choose a suitable machine(machine size and available motions etc). Once the machine basic model confirmed, we can then customize machine technical properties as following. Motor - machine motion control is powered by servo motors. By default it's configured by Panasonic production which is very stable since from the very start. But if you have specific…

No matter how you compare from various robot solutions, global robot precision speed reducers are basically monopolized by Japan. In recent years, although there are other RV reducers, rarely used by robot companies like us. As a traditional manufacturing powerhouse, reducer products in Germany, Italy, Japan are leading the industry in terms of materials, design level, quality control, accuracy, power density, reliability and service life. In the field of mechanical transmission, reducer is an intermediate device that connects the power source and actuator. Usually, it uses the high-speed power of the motor and internal combustion engine to engage the large gear on the output shaft through small gear on the input shaft to reduce speed And transfer more torque. Driven by the development of aerospace, robotics, and medical equipment, the…

The work principle of electrostatic powder coating is almost the same as liquid electrostatic coatings, except that powder spraying is dispersed not atomized. It is a coating sprayed by an electrostatic powder spray gun. While dispersing, the powder particles are negatively charged. The charged powder particles are processed by air flow (or other forces such as centrifugal) and electrostatic attraction to be coated on workpiece. Then heated to melt and solidify to form a hard film. Electrostatic powder coating is primary choice for lost of hardware coating projects. Electrostatic Powder Coating Advantage Electrostatic powder coating is popularly known as "plastic powder spraying". Electrostatic powder coating is powered by a coating machine with an atomizing nozzle (to atomize the powder) and a discharge level (to generate electricity and current) to atomize…

In plastic painting line system, flame(or flamming) treatment is a popular setup to meet with high end painting requirements over different plastic materials. Especially for PP plastic, flamming is a must process for guaranteed contact to coating film. In this article we will introduce why it's important and how it works. Flame treatment refers to the process of oxidizing plastic surface with a strong oxidizing flame. It is mainly used to improve the painting characteristics and adhesive characteristics of polyolefin plastics. The technique is to increase surface activity and increase the primer adhesion to workpiece surface. Definition In order to facilitate the foaming compounding process, plastic surface tension value must meet the production requirements, surface tension value is generally required to reach about 41 dyne. However, polypropylene material surface tension…
