1, Net frame. The screen frame used for acrylic box screen printing generally has two types: wooden frame and aluminum frame. The price of the wooden frame is cheaper than that of the aluminum frame, but the pulled out net is easy to loosen, so the recyclability is relatively poor, and the aluminum frame is more recyclable than the wooden frame.
2, the mesh. There are many kinds of mesh yarns, such as nylon mesh yarn, silk mesh yarn, metal mesh yarn, etc., but nylon mesh is generally used.
3, pull the net. There are manual pulling nets, mechanical pulling nets, and pneumatic pulling nets, but for general acrylic box processing factories, because their requirements for printing are not very high, it is possible to use manual pulling nets and mechanical pulling nets. Yes, the pneumatic pull net is not very useful.
4, wash the net. Chemicals for washing nets are time-consuming, and professional acrylic box processing factories generally use detergents with strong decontamination directly. Wet the screen and then polish it with cotton cloth on both sides. When grinding, the force should be light to prevent the mesh from falling off, and then put it in the dryer for drying.
5, on the photosensitive paste. The photosensitive paste on the market needs to be called by yourself. First, use hot water to wet the photosensitive powder for screen printing, then pour it into the photosensitive paste and mix it thoroughly, and set it aside for later use. There are automatic sizing machines on the market, the thickness is very uniform, and it can also be sizing by the plate maker.
6. Baking and publishing. The baking plates are generally baked in a baking machine with a warm air of about 30 degrees, and they are baked several times after sizing. The baked stencil must be dry. The thickness generally depends on the needs of the acrylic box. For PVC , film and other thin general once on it. When publishing, attention should be paid to the integrity and smoothness of each character.
