In addition, MoldMAX offers athermal conductivity up to ten times greater than steeland comparable to aluminum. MoldMAX is typically specified for: Injection mold components and cavity inserts Blow mold pinch offs, neck rings and handle inserts Hot runner system injection nozzles and manifolds MoldMAX SC provides the highest thermal conductivity available in a mold material…ten times greater than steel and twice that of aluminum. MoldMAX SC also offers a hardness and strength exceeding aluminum. MoldMAX SC is specifically designed for foam processing, hot runner systems, blow molds and other applications where maximum heat removal or control is required. ATTRIBUTES Heat treated and ready to machine Resistant to corrosion Fully machinable Easy to polish Can be welded to copper and other alloys Available in large block sizes High levels of strength and conductivity 縮短生產周期、產品成本降低 改善產品的質量，以致有效減低廢品率 快3倍的機械加工速率，模具和縮短交貨時間令模具的加工成本降低 類似模具鋼的加工方法，無需大量的加工變動 超過一百萬次的生產周期，使維修費用降低 模具減低設計和成本降低 減少的成本和提高的產品質量，以致每件產品成本降低 moldMAX®提供類模具鋼的強度和耐磨性，和可與鋁材媲美的導熱性能，為鋼材的三至四倍。moldMAX®一般被指定用于整體型腔和型芯、吹塑模的切膠位、頸圈及手柄鑲塊、整體型腔和型芯內鑲塊、注塑模具配件、和熱澆注系統的噴嘴和集管等。 在現有的模具材料中，PROtherm®提供最高的導熱性能，超過鋼材的十倍之多，亦為鋁材的兩倍。PROtherm®還提供高子鋁材的硬度和強度。PROtherm®是專門為于泡沫成型、型芯頂蓋、熱澆注系統以及其他需最大熱量移除或控制的應用。 導熱性能的優點 模具設計可充分利用這些合金的導熱性能與強度的優良組合，塑膠產品從而獲得迅速而更均勻的熱量移除。最大效益是產品較少的模塑后的翹曲和收縮。一旦模塑參數達最優值，生產周期可縮短和更佳的尺寸控制。使用moldMAX®和PROtherm®的集管設計可導致更均勻的塑料熔融溫度的控制。將更均勻和已預計的塑料熔融傳送到模具型腔，以致更好優質的質量控制。 耐磨性的優點 模具壽命旳基本因素取決于抗磨耗和黏合的性能。moldMAX®具備優良的抗磨耗性能,以作型芯和型腔鑲塊及注塑模具配件時可直接與塑料接觸。 耐腐蝕性優點 moldMAX®和PROtherm®，皆為銅基本合金，提供極佳的抗腐蝕性能，如耐鹽酸、耐碳酸、及由于注塑加工而產生的類似分解 酸性物質。結果，這兩種合金都十分適合作為潛有腐蝕性塑料的模具，如PVC。 加工性能的優點 moldMAX®和PROtherm®可作任何加工。在傳統的加工工序，moldMAX®和PROtherm®的機械加工性能是鋼材的3倍。 可補焊的優點 與鋼材和鋁材不同，moldMAX®和PROtherm®模具易于進行補焊維修，不會影響模具的整體強度。建議采用鎢極惰性氣體作保護電弧焊接法（TIG/GTAW）和金屬焊條惰性氣體保護電弧焊接法（MIG/GMAW）。 建議采用WeldPak®是焊條。WeldPak®是moldMAX®的棒材，長度為三尺和3/32¨、1/16¨、1/8¨的直徑或這些直徑的組合數量。 表面處理 moldMAX®和PROtherm®的耐磨性、抗腐蝕性和脫模可采用標準的表面處理而增加性能。moldMAX®和PROtherm®可以表面鍍鉻、無電極鍍鎳、氮化鈦和二硫化鎢。如需更多詳細資料，請與我們的客戶技術服務部門聯絡。 減少生產周期 Weatherchem公司是一家塑料產品制造商，其草地自動灑水系統的調節旋鈕配件于注塑過程中，因采用moldMAX®作襯套及PROtherm® 取代沿用的模具鋼材作內芯(PT-18): 縮短生產周期41%。因此生產周期由37秒縮短到22秒。襯套采用moldMAX HH(高強度MM40)增加了將熱量從塑料產品移除的效率。 設計自由度 Carlon公司是一家領導市場的PVC導管及接頭的的制造商，他們采用moldMAX HH® (MM40)改良光纖導管接頭的模具。沿用的不銹鋼型芯模具在不到2千個周期，在底部開裂。Carlon采用moldMAX®的熱傳導性能和強度的獨特組合而簡化型芯的冷水道系統，因而增加模芯的強度以消除開裂的失效。 供貨 moldMAX®和PROtherm®已預硬狀態供貨，MoldMax HH (MM40)和LH (MM30,30HC硬度)均以板材，捧材，及管材的標準尺寸供貨特定尺寸和經切鋸后的尺寸可從特約經銷商采購。 moldMAX®型芯銷和起模桿，硬度最小值為HRC40，同樣也以4¨、8¨、12¨和18¨的長度供貨，圓柱直徑范圍從1/8¨到1¨。如果您想了解更多信息，可參見Brush Wellman的型芯銷和起模桿數據表。
