PVC molding characteristics: 1. amorphous material, moisture absorption is small, illiquid in order to improve liquidity and prevent bubbles, plastic mold casting system can be pre-drying should be chunky, gate-section should be large, dead mold may not have to be cooled. , chrome plated. 2. Because of its corrosion resistance and flowability characteristics, the best use of special equipment and tooling. All products shall be added to the different types and quantities of additives needed. 3. easy to decompose at temperatures of 200 degrees and steel. Copper contacts easier to break down, escape corrosive decomposition. Irritant gases. Small molding temperature range 4. When using screw injection machine nozzle aperture should be large, to prevent Lag dead material. really belt inserts, inserts should be preheated if (1) coating method. Operation of heating and mechanical lawn fence PVC coating method, a layer of black film and adhesive bonding surface connected via steel railings pvc lamination. Fu is the: Health and manufacturing processes required in the pipeline promising line of PVC balcony rails, better quality of film and adhesive glue required to use imported manufactured goods PVC fence flower beds, high cost; the construction of black film will not be a bad bruise damage repair . (2) Surface spraying. The black spray paint evenly in the steel railing visible surface pvc death, single spray can also be double-sided coating. Fu is the color variety, raw manufacturing construction flexibility. St. Ye metal, PVC fence communities, PVC is provided by St. Ye metals.
