screen printing frame tense steps 1. Surface treatment of screen frame Metal mesh frame before the mesh. Rough and decontamination treatment to increase adhesion.When decontamination grease, must not use oily cleaner.Net frame edge can not have sharp edges and corners, to prevent damage to the screen under the tension of the network.If it is the first use of the mesh frame, need to use fine sandpaper gently friction, make the surface of the mesh frame rough, so easy to improv

1. Wooden screen frame Wooden screen frame has simple production, light weight, easy to operate.Low price, stretch network method simple characteristics, this screen frame is still widely used in manual printing, especially small surface printing.But the wood material solvent resistance, poor water resistance, easy to deformation after water immersion, will affect the printing accuracy.There is a tendency to be gradually replaced by metal mesh frames.At present, it is mainly used in man
Today I would like to introduce the beat cutting. Beating is a special engraving of aluminum.The grinding wheel keeps pushing forward, and between the electric flint, the smooth profiles show a wavy pattern.Accurate grasp of technology and strength makes aluminum and mesh better fit, and finally presents a perfect stretching and mesh effect. First of all, accurate measurement and calculation of 6 m long aluminum profiles are carried out.The experienced master then USES skilled tec
Selection of photosensitive materials Screen printing screen screen is required to reproduce the image.An important factor in determining reproducibility is the selection of a good photosensitive material.The so-called screen printing plate reproduction refers to the screen screen of the original image reproduction ability.It is shown in screen printing plate precision, clarity, differentiation and other aspects. oneScreen printing plate accuracy.
