1. Product Overview
We provide one-stop custom Injection Mold development and PP straight connector molding service. This tubular straight connector is molded from virgin PP material, matched with tailor-made Injection Mold produced from S136 stainless mold steel hardened to HRC48-52. This Injection Mold features 1×8 multi-cavity layout, producing eight straight connectors per molding cycle to improve production efficiency. Submarine hidden gate structure is adopted for clean product surface without manual gate cutting. All finished Injection Mold passes strict dimensional test before shipment to support stable long-term mass production of PP pipe connectors.

3. Core Advantages
1. High-Grade S136 HRC48-52 Injection Mold
S136 stainless steel has excellent rust-proof, anti-corrosion and wear resistance under HRC48-52 hardness, effectively avoiding mold rust during long-time PP continuous production and prolonging the service life of whole Injection Mold. Polished cavity ensures smooth connector surface with no flow mark or scratch, low reject rate.
2. 1×8 High-Efficiency Multi-Cavity Design
Eight finished straight connectors are formed in one single shot, greatly shorten molding cycle and reduce unit production cost, perfect for large-volume bulk orders.
3. Submarine Hidden Gate Advantage
Submarine gate automatically breaks off during product ejection, no gate residue left on connector outer wall; save post-trimming labor and keep neat appearance of straight connector.
4. Superior PP Material Property
PP features outstanding chemical resistance, high rigidity and good connecting tightness, the straight connector fits tightly with plastic pipelines for smooth fluid transmission.
5. Full Customization Support
We design and manufacture complete set Injection Mold per customers’ 2D/3D drawings or physical samples; customizable connector inner/outer diameter, length and mold structure.
