1. Product Overview
We offer integrated custom Injection Mold fabrication and PP straight connector injection molding service. This plastic straight connector is molded with virgin PP material, paired with precision customized Injection Mold built from S136 stainless mold steel tempered to HRC48-52. The Injection Mold adopts fully polished mold cavity plus mature submarine hidden gating structure to deliver blemish-free connector surface. All finished Injection Mold undergoes strict dimensional & appearance inspection before dispatch to ensure stable long-run mass production.

3. Key Advantages
✅ Premium S136 HRC48-52 Injection Mold
S136 steel owns superior anti-rust, corrosion and wear resistance at HRC48-52 hardness, effectively preventing mold rust during continuous PP molding and extending the lifespan of the whole Injection Mold. Polished cavity eliminates sink marks, flow lines and scratches on connector surface to cut defective ratio.
✅ Submarine Hidden Gating Structure
Submarine gate automatically separates from parts while ejection; no leftover gate burr on connector outer surface, remove manual trimming procedure and save post-processing cost greatly.
✅ Excellent PP Connector Performance
PP features fine chemical resistance and structural rigidity, enabling tight leak-proof connection for fluid pipelines, widely applied in liquid conveying fittings.
✅ Full Customization Available
We tailor the complete set of Injection Mold as per clients’ 2D/3D drawings or physical samples, adjustable connector size, inner bore and mold structure according to your project demand.
