The choice of PVC resin mainly considers two aspects. Namely: hygienic and processability;
1. Hygienic production water supply pipe parts must use food hygiene grade PVC resin, the residual amount of vinyl chloride monomer (VCM) in the resin is less than 5mg/kg;
2. Processability Because the water supply pipe parts are hard PVC products without plasticizing, it is necessary to select a resin with a smaller average degree of polymerization when injection molding. That is, domestic SG6 type and SG7 type resin, or other grade resin corresponding thereto.
Drying treatment: Drying is usually not required.
Melting temperature: 185~205C.
Mold temperature: 20~50C.
Injection pressure: up to 1500 bar Holding pressure: up to 1000 bar Injection speed: In order to avoid material degradation, a considerable injection speed is generally used.
Runners and gates: All regular gates can be used. If you are working with smaller parts, it is best to use tip-type gates or submerged gates; for thicker parts, it is best to use fan-shaped gates. The minimum diameter of the tip or submerged gate shall be 1 mm; the thickness of the fan gate shall not be less than 1 mm.
