1*4 PP Material S136 HRC48-52 Mold Steel Polished Cavity Submarine Gating Bended Connecter with Valve Custom Molding

This customized bent connector is precision-manufactured via professional injection mold molding, crafted from premium PP raw material, with matching tailor-made injection mold built by S136 stainless mold steel. Our 1×4 cavity injection mold adopts polished cavity surface, submarine tunnel gating plus built-in valve structure, supporting stable mass custom molding for bent connector fittings. Our factory supplies both finished PP bent connector and exclusive custom injection mold development & injection molding one-stop service, all injection mold are strictly inspected before delivery for long-lifespan production.

✅ Premium S136 Mold Steel Injection Mold: S136 mold steel features superior anti-corrosion & wear resistance at HRC48-52 hardness, the polished cavity delivers ultra-smooth product surface without secondary polishing, greatly improving finished connector appearance and reducing defective rate of injection molding. ✅ Submarine Hidden Gating Design: Submarine tunnel gate automatically cuts off during product ejection, no manual gate trimming needed; hidden gate leaves no ugly mark on connector outer surface, ideal for automated high-volume injection molding production, cuts down post-processing cost effectively. ✅ 1×4 Multi-Cavity Injection Mold: Four identical cavities in one single injection mold, 4 finished bent connectors per molding shot, shorten production cycle and boost daily output for mass order. ✅ Integrated Valve Custom Structure: Built-in valve design inside bent connector body ensures stable flow control when assembling into pipe/medical air circuit, tight sealing performance for fluid/gas connection application. ✅ Customization Flexibility: We tailor-make whole set injection mold as per client’s 2D/3D drawing, adjust connector dimension, PP material grade and injection mold cavity layout to match unique project requirement.

Q1: Can you modify existing injection mold for connector dimension adjustment? A: Yes, our mold workshop supports mid-project modification on finished S136 injection mold to revise bent connector size per updated drawing.

Q2: What is the service life of S136 HRC48-52 injection mold? A: Properly maintained polished S136 injection mold can reach over 500,000 shots of PP injection molding for long-term bulk production.

Q3: Is small-batch sample order available before mass molding? A: Available, we produce trial samples via finished injection mold first for client inspection before formal bulk custom molding.

Q4: Can we switch other plastic material (ABS/PE) on same injection mold? A: The current submarine gating injection mold is optimized for PP; minor mold tweak allows compatible molding of similar thermoplastic materials after technical evaluation.
