@alpine.mold.china: Internal undercuts causing demolding problems? 👀 This mold uses a front slider with internal core pulling. An angle pin drives the slider inward during mold opening, releasing the inner undercut before demolding. No hydraulic cylinder needed — simpler structure, stable operation, and better for mass production. At Alpine Mold, we design custom mold structures around your part geometry. 📩 DM is always welcome for project discussions. 🌐 Website: www.alpine-mold.com 📧 Email: [email protected] 📞 +86 181 6575 6039 #molddesign #moldengineering #injectionmolding #tooling #moldmaking#manufacturing
