Skyler Jenkins 縮小模具硬幣戒指拉伸器（延展框架）

硬幣戒指版

包含全新的硬幣戒指縮徑模具，取代傳統的縮徑模具。

從頭開始設計，這款 Pepetools 的戒指擴張器在品質、一致性和可靠性上樹立了標竿。我們從機器的核心——花鍵開始設計。花鍵由實心工具鋼胚料加工而成。同心度是均勻、平滑拉伸實心戒環的關鍵。每個 6 花鍵從 CNC 車床開始，經過加工，然後在內徑上鉸孔，以創造出完美同心的錐體。這項專有製程耗費多年的工作、工具和知識，才創造出獨一無二的產品。

不僅止於花鍵，縮徑模具也是由實心胚料加工而成（市面上大多數是鑄造的）。16 個埋頭模具在一個將近 1" 厚的 4.5" 圓盤上，以 8 方式加工。每個埋頭孔都使用專用工具加工，形成完美的 17 度角。

花鍵、縮徑模具和所有鋼製零件都經過拋光，並鍍上耐用的硬質塗層，以確保使用壽命。

除了革命性的設計製程，我們更進一步。我們很自豪能成為第一家推出選配 Delrin 縮徑模具和推桿的製造商。這在縮徑較軟材質的戒環時是一大優勢。耐用的 Delrin 縮徑模具和推桿有助於防止刮傷。無論是硬幣戒指、實心金或鉑金戒環，或任何其他非鐵金屬材料——這款 Pepetools 的戒指擴張器都將是您工作坊中的得力助手。

#sponsored for this week’s #tooltalktuesday I am super excited to show off my @pepetools_usa Ring Stretcher + Reducer - This awesome tool will stretch (or reduce) a ring with a few pulls of it’s lever! I was fortunate enough to use a ring stretcher/reducer in college and have been in love with them ever since, they are a wonderful tool to have in your studio. If you’ve never used one here is the deal: you bolt this thing down in your studio and then it’s ready to go. By placing a ring on the top part (called the spline) you then pull the handle and it evenly applies force around your band. You can do it very incrementally and check against a mandrel as you go. The reducer works by placing your ring inside the die and then the ram pushes it down, which decreases the size. While experimenting I was able to take a size 8 and first stretch it to an 8.25 then I reduced it back down to a size 6 in seconds! What makes this one from Pepe go above and beyond is the spline is made from machined steel (instead of cast steel like many other stretchers) which means it won’t mar your metal! This also comes with a delrin reducing die and reducing ram, this material helps protect against marring when reducing the size of your ring! It saves a lot of time when you can adjust size but not have to polishing out marks! I have also found this tool can be really effective for work hardening a ring, so if I intentional make my finished ring a quarter size too small and then give it a few small stretches (careful not to go overboard) it will evenly harden the ring. I would not recommend placing rings with stones on this but its perfect for fabricated bands and castings! I have a signet ring in my collection that I can easily stretch a little if need be and this saves me a ton of time, and saves me from having to create a whole new ring. I can also remember when I was in college stretching a ring too much and popping my solder seam, so learn from mistakes ;) You can find these stretchers at pepetools.com or from our friends @aajewelrysupply Would love to hear from those that have used a stretcher/reducer ❤️ Kindness, Community +Education! #jewelrymakingtools #pepetools #ringstretcher
