Injection Mold Processing Design Metal Products Shell Daily Necessities Factory Mold Precision Plastic Shell Zhejiang

These precision injection molds are custom-made for plastic pipe fittings, manufactured by Junrui Mould & Plastic Co., Ltd. Our mold lineup includes multi-cavity straight pipe molds, angled elbow core molds, multi-cavity 90° bend fitting molds and slide core pipe fitting molds, covering most common plastic pipeline accessory production demands.

Mold Craftsmanship & Advantages

1. High-precision CNC Machining Structure
Every mold cavity, slide block, inclined core and guide pillar is processed by 5-axis CNC equipment with micron-level tolerance control. Smooth mold surfaces eliminate burrs on finished plastic pipe fittings, ensuring consistent product wall thickness and perfect sealing performance.
2. Diversified Cavity & Demolding Solutions
We supply single-cavity, 4-cavity and 8-cavity multi-cavity molds to match different mass production volumes. Equipped with professional inclined slide core mechanisms for bent, angled pipe elbows; stable side drawing demolding structure avoids product deformation during ejection.
3. Long Service Life Mold Steel
Core mold components adopt wear-resistant mold steel with professional quenching and tempering treatment. The mold base is thickened and reinforced to withstand long-term high-speed injection cycles, extending mold service life to over 500,000 shots with stable output.
4. Custom One-stop Development
Support full customized development according to your pipe fitting drawings, samples and application scenarios (water supply, drainage, industrial pipeline). We complete mold design, CNC processing, polishing, assembly and trial molding in-house, and provide production test samples before delivery.
5. Fully Traceable Production Records
We document every processing procedure of each mold. Production inspection records are stored in our workshop, available for clients to check during factory visits. Weekly equipment maintenance guarantees stable mold performance for long-term batch production.

Application Scope

Our pipe fitting molds produce PP, PVC, PPR plastic pipe connectors, straight joints, 45°/90° elbows, tee joints and other pipeline accessories, widely used in household plumbing, construction drainage, agricultural irrigation and industrial fluid delivery systems.
