DN110 PVC-U 45° Elbow Pipe Fitting Mould
SINO Mould specializes in R&D and manufacturing of DN110 PVC-U 45° elbow pipe fitting mould for national-standard building drainage systems, applied for 45degree turning connection of 110mm drain pipes. Special anti-corrosion and mold-flow optimizations are adopted for rigid PVC material which features corrosive gas release and poor fluidity. Hydraulic cylinder core pulling mechanism enables automatic core pulling and demoulding for both inner bores of the elbow. Finished parts obtain smooth inner surface, accurate socket dimension, good interchangeability and leak proof glue joint performance. Available in 1cavity or 2cavity configuration with cold runner large gate feeding, compatible with standard horizontal injection machines. It is widely used for mass production of pipe fittings for residential drainage, municipal sewage and construction projects, helping pipe manufacturers cut unit production cost effectively.

Key Advantages of DN110 PVC-U 45° Pipe Fitting Mould
Dual-cylinder synchronous hydraulic core pulling mechanism: Synchronous core pulling for two sockets of DN110 large elbow. Stable movement prevents inner bore scratch, guarantees socket roundness.
Special anti-corrosion solution for PVC: Cavity and core adopt S136 stainless steel. Optional hard-chrome plating resists corrosive gas decomposed by high temperature PVC and delays mould rusting to extend service life.
Circulating surrounding cooling design: Reinforced cooling at elbow bending and socket positions for uniform cooling, minimizing shrinkage, deformation and sink marks, ensuring accurate 45-degree angle.
Mold-flow analysis: Predict defects such as air trap, burn mark and weld line for PVC material, reduce test mould times and reach mass production requirement at first trial.
Modular insert design: Separated socket inserts & wear resistant slides, replaceable individually after wear, low maintenance cost and short downtime.
Standard spare parts: HASCO / DME standard water nozzles, oil cylinders, guide pins & guide sleeves, convenient spare part purchasing locally.
Customization: Part logo engraving, mould marking, wall thickness adjustment, non standard socket modification available.
