1. Product Overview
We provide one-stop customized Injection Mold fabrication and PA66+30GF pipe nipple injection molding service. This long cylindrical plastic pipe end nipple is molded with 30% glass fiber filled PA66 engineering plastic, matched with tailor-made Injection Mold manufactured from premium XPM pre-hardened mold steel tempered to HRC37~43. The single-cavity Injection Mold is equipped with combined submarine hidden gate + side gate feeding system, while mold cavity surface is finished with standard VDI24 uniform etching texture. All finished Injection Mold passes strict dimensional and surface inspection before shipment for stable small-batch & prototype mass production of high-strength pipe nipples.

3. Core Advantages
✅ Premium XPM HRC37-43 Injection Mold
XPM pre-hardened steel features stable uniform hardness HRC37-43, excellent polish & texture etching performance, great wear resistance especially for GF-filled PA abrasion molding. VDI24 standard cavity texture avoids part surface shiny slip mark, improves nipple outer anti-slip appearance while covering minor molding flow traces, effectively lower reject rate during continuous PA66+30GF injection.
✅ 1×1 Single Cavity Custom Design
Single cavity mold perfectly fits new product prototype development and small customized batch orders, flexible for dimension revision on pipe nipple length & outer diameter without huge mold modification cost.
✅ Dual Submarine + Side Hybrid Gate System
Submarine hidden gate is set on nipple’s smooth outer cylinder surface for automatic break after ejection with invisible gate residue; side gate is arranged on nipple’s thickened end cap to guarantee full molten plastic filling, eliminate short-shot defect on closed end structure of long cylindrical nipple.
✅ High Strength PA66+30GF Pipe Nipple Property
30% glass fiber reinforced PA66 brings outstanding tensile strength, high temperature resistance and dimensional stability, the solid cylindrical nipple realizes tight plugging & sealing for fluid pipeline, resistant to creep deformation under hydraulic pressure.
✅ Full Customization Available
We revise nipple total length, outer diameter and VDI texture grade on the Injection Mold per clients’ 2D/3D drawings or physical samples, optional material switch to unreinforced PA66/PP upon requirement.

FAQ Section
Q1: How many molding shots can this XPM Injection Mold run?
A: With regular maintenance, the HRC37-43 XPM Injection Mold can steadily reach over 480,000 shots for abrasive GF-filled PA66 pipe nipple production.
Q2: Can we modify nipple length or diameter on finished Injection Mold?
A: Our in-house mold workshop can revise core insert to adjust nipple dimension based on updated technical drawings.
Q3: Can customers get pre-production trial samples before bulk order?
A: Yes, we arrange PA66+30GF prototype samples after mold completion for your strength & dimension verification.
Q4: Can this Injection Mold produce unreinforced PA66 plastic nipple?
A: Available after injection parameter fine-tuning and gate flow adjustment via our technical evaluation.
