The catch with a single-cavity cold runner tool like this is it's not your best bet if you're chasing maximum output on a 24/7 production line—those run-hot cycles will wear the P20 core faster when PP fills at high shear rates, so we usually recommend this for low-to-mid volume runs where you value tool longevity over shot speed.
That 28-second average cycle time means you're looking at roughly 1,500 parts per shift give or take a hundred, which actually works fine for most job shops knocking out household lids or industiral caps, and the 718 steel in the cavity plates holds up better than P20 against the SBS impact modifiers some PP grades use.
SGS and BV certification comes standard, but what's not on spec sheet is we toss in 30% free replacement parts—core pins, ejector sleeves, that kind of stuff—so you're not hunting for spares when a pin snaps after 150,000 shots, and the 2-year any warpage or dimensoin drift that exceeds 0.05mm.
Design runs off AutoCAD 2D/3D with DME standard components, so you can basically drop this into an existing tooling rack without modifying your injection press's tie-bar spacing or knock-out pattern, though for PP you'll want to confirm your screw's L/D ratio handles the melt flow index (usually 10-20 g/10min) we optimized the gate size for.
Do not use this for glass-filled PP—the cold runner and single-cavity layout will trigger premature gate wear and fiber orientation issues, so stick with unfilled or talc-filled grades under 20% loading, and the polished surfce finish leaves a Class A cosmetic surface that many molders don't realize requires dry-blast texturing first. Anyway, minimum order is one set with a 6 to 10 week lead time, packed in an export wooden crate with shock-absorbing brackets, and our company can tweak the runner cross-section for thicker-wall parts (3-5mm range) at no extra charge.
It's just 1 set. So if you need a single custom mould, we've got you covered.
Yes, we include SGS and BV certification. You can request inspection reports or third-party testing before shipment.
That time covers design, CNC machining, EDM, and testing for your custom mould. If you need it faster, we can discuss rush options—just depends on complexity.
Yes, we include 30% free spare parts with your mould. That covers critical wear items like ejector pins or springs to keep production running.
It covers manufacturing defects for the whole mould, like steel cracking or cavity wear—but not damage from improper use or regular wear on consumables like slides.
