pvc pipe drying conditions: usually do not require drying. Melting temperature: 185 ~ 205C. Mold temperature: 20 ~ 50C. Injection pressure: can be as large 1500bar holding pressure: can be as large as 1000bar injection speed: To avoid material degradation, the general use of the injection speed considerably. Runners and Gates: All conventional gate can be used. If the processing of smaller components, it is best to use the tip gate or sneak into the gate; for thicker parts pvc pipe, it is best to use the fan gate. The minimum diameter of the tip gate or sneak into the gate should be 1mm; fan gate thickness not less than 1mm. Typical uses: pvc pipe water supply pipeline agents, household pipes, house siding, business machine housings, electronics packaging, medical equipment, food packaging. pvc Features 1. amorphous material Qingdao pvc pipe, moisture absorption, poor mobility, in order to improve liquidity, pvc pipe threads to prevent air bubbles, should advance to dry. 2. easy to decompose, especially at elevated temperatures in contact with steel, copper easier decomposition (decomposition temperature of 200 degrees). Forming small temperature range, the material temperature must be strictly controlled. 3. When using screw injection machine and straight nozzle aperture should be large, to prevent stagnation dead material. 4. Die casting system should be thick, the gate should be large cross-section, the mold should be cooled, the mold temperature 30-60 degrees, the material temperature 160-190. PVC may be ethylene, chlorine and the catalyst is made by a substitution reaction. Because of its role in fire resistant, PVC is widely used in all kinds of industries: Cable sheath, fiber jacket, shoes, handbags, bags, accessories, signs and billboards, building and decorating supplies, furniture, ornaments , rollers, pipes, toys (such as the famous Italian "Rody" jumping horse), curtain, rolling door, auxiliary medical supplies, gloves, plastic wrap certain foods, such as certain fashion.
