Bent tube with deep undercuts? That’s one of the toughest challenges in injection molding. Deep undercuts = ❌ Parts stuck ❌ Drag marks ❌ Whitening ❌ Slow cycle time And this part was even harder — multiple undercuts in different directions. Here’s how we solved it 👇 🔧 12-insert collapsing core system • Each insert retracts independently • Synchronized movement → smooth release • No drag marks, no whitening • Clean T1 success Why choose Alpine Mold? ✔ DFM Moldflow before design ✔ Strong experie

Alpine Mold on Instagram: "🔧 Complex Undercuts on a Bent Tube Part? Solved in One Go. Bent tube injection parts often share the same headache: deep undercuts + complex geometry = difficult demolding. If not handled well, it leads to: ❌ Stuck parts ❌ Drag marks / whitening ❌ Longer cycle time ❌ Unstable mass production This project was even tougher — 👉 a bent tube with multiple deep undercuts in different directions. 🧠 Our solution After DFM review, our engineers confirmed: A traditional slide

Alpine Mold on Instagram: "Ever had a mold delay your entire project? Especially consumer electronics molds with tight tolerances and demanding assembly requirements? That’s exactly why this Bluetooth earphone mold project mattered. Usually, these molds take much longer — complex parting lines, precision inserts, and multi-cavity alignment. But at Alpine Mold, we completed the T0 trial in just 20 days. Here’s how we made it happen: ✔️ Early DFM + Moldflow to avoid design mistakes ✔️ Experienced

Alpine Mold on Instagram: "What does an angled lifter do in injection molds? The angled lifter (lifter slide) releases undercuts that sliders can’t reach. When the mold opens, the guide pin drives the lifter to move upward and outward, allowing it to pull the undercut and push the part out in one motion. When is it used? ✔ Deep or internal undercuts ✔ Bottom-side hooks or snaps ✔ Areas too tight for a slider ✔ Designs requiring both “eject + de-core” at the same time With this mechanism, complex
