Plastic plates | plastic plates made four - process Guangzhou gains plastic signs factory

Plastic sign four kinds of production process in the life we often see some plastic sign identification, such as: parking warning marks, don't take out the trash, no smoking signs, ban labeled, guide instruction, elevator prompt sign and so on. These logos are often made of plastic as a sign of substrate material, with the widely application of the plastic and development, production process and material is also different, the making craft of plastic signs to roughly the following four types: (1). Directly on plastic molding content such as Numbers, text, design symbol: products material is commonly engineering plastic instrument panel, chassis, chassis, electronic equipment, parts, components, plastic components such as buttons, the remote control. Used directly on the plastic molding and characters of the method is relatively simple, this kind of method is carved on the parts of injection mold can be text, graphics, or symbol. The benefits of using braille is engraving is simple, render content stereo sense is strong. Concave mould processing relatively time consuming, but concave word content is not easy to damage. Efficiency of this method is obvious than other sides labeling method to save time and cost, the disadvantage is that the font clear degree is not obvious, and only used for the content of the plastic molding is relatively simple. ②。 Secondary double color injection molding plastic sign: this method is of high production efficiency, save non-ferrous metals. Content of uniform plane, the plastic tag is easy to use the font clear, durable, suitable for making size slightly larger digital content of plastic signs or symbols, signs, etc. Secondary injection molding method: first forming digit symbol as the plastic embedded parts, injection molding plastic frame, reverse order it doesn't matter. When select material should be wary of the first injection molding plastic insert melt temperature should be higher than after molding plastic thimble temperature, in order to prevent the second injection molding, the original insert surface melting, affect the surface. ③。 Polyester film sign: polyester film effect is similar to metal, polyester film ( The thickness of 0. 05 - 0. 15mm) With metallic simple sense. For a variety of special-shaped or complex parts, components, application is very convenient, this was less than other signs, plastic signs. Suitable for the production of specifications smaller Polyester film sign method: by photoengraving method make printing paint roller gravure copper plate and chrome plated, then paint on the polyester film and drying. Then through the vacuum aluminum plating, paint on the part of the plating on not light thin aluminum layer, after clipping with adhesive on the products. Then the high and low temperature test and humidity test, confirmed that no blister fall off or not firm adhesion. ④。 Organic glass plastic plate production process: especially the organic glass bead light, hand glue after machining. The plastic tag content clear and beautiful, colour diversity, have stereo feeling, but cost materials, work, capital is higher. Modelling the demand is higher, difficult for the production of sign products.
