THE MOLDMAX® ADVANTAGE
Through the unique combination of thermal conductivity and strength available in The MoldMAX product line, these copper mold alloys provide:
Shorter cycle time
Improved plastic part dimensional control
Better parting line maintenance
Excellent corrosion resistance
MoldMAX provides strength and wear resistance similar to that of many tool steels. 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.

moldMAX®提供類模具鋼的強(qiáng)度和耐磨性,和可與鋁材媲美的導(dǎo)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(nèi)鑲塊、注塑模具配件、和熱澆注系統(tǒng)的噴嘴和集管等。
在現(xiàn)有的模具材料中,PROtherm®提供最高的導(dǎo)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(qiáng)度。PROtherm®是專門為于泡沫成型、型芯頂蓋、熱澆注系統(tǒng)以及其他需最大熱量移除或控制的應(yīng)用。
導(dǎo)熱性能的優(yōu)點
模具設(shè)計可充分利用這些合金的導(dǎo)熱性能與強(qiáng)度的優(yōu)良組合,塑膠產(chǎn)品從而獲得迅速而更均勻的熱量移除。最大效益是產(chǎn)品較少的模塑后的翹曲和收縮。一旦模塑參數(shù)達(dá)最優(yōu)值,生產(chǎn)周期可縮短和更佳的尺寸控制。使用moldMAX®和PROtherm®的集管設(shè)計可導(dǎo)致更均勻的塑料熔融溫度的控制。將更均勻和已預(yù)計的塑料熔融傳送到模具型腔,以致更好優(yōu)質(zhì)的質(zhì)量控制。
耐磨性的優(yōu)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(yōu)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(yōu)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(chǎn)生的類似分解 酸性物質(zhì)。結(jié)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(yōu)點
moldMAX®和PROtherm®可作任何加工。在傳統(tǒng)的加工工序,moldMAX®和PROtherm®的機(jī)械加工性能是鋼材的3倍。
可補(bǔ)焊的優(yōu)點
與鋼材和鋁材不同,moldMAX®和PROtherm®模具易于進(jìn)行補(bǔ)焊維修,不會影響模具的整體強(qiáng)度。建議采用鎢極惰性氣體作保護(hù)電弧焊接法(TIG/GTAW)和金屬焊條惰性氣體保護(hù)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(shù)量。
表面處理
moldMAX®和PROtherm®的耐磨性、抗腐蝕性和脫??刹捎脴?biāo)準(zhǔn)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(xì)資料,請與我們的客戶技術(shù)服務(wù)部門聯(lián)絡(luò)。
減少生產(chǎn)周期
Weatherchem公司是一家塑料產(chǎn)品制造商,其草地自動灑水系統(tǒng)的調(diào)節(jié)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(nèi)芯(PT-18): 縮短生產(chǎn)周期41%。因此生產(chǎn)周期由37秒縮短到22秒。襯套采用moldMAX HH(高強(qiáng)度MM40)增加了將熱量從塑料產(chǎn)品移除的效率。
設(shè)計自由度
Carlon公司是一家領(lǐng)導(dǎo)市場的PVC導(dǎo)管及接頭的的制造商,他們采用moldMAX HH® (MM40)改良光纖導(dǎo)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(dǎo)性能和強(qiáng)度的獨特組合而簡化型芯的冷水道系統(tǒng),因而增加模芯的強(qiáng)度以消除開裂的失效。
供貨
moldMAX®和PROtherm®已預(yù)硬狀態(tài)供貨,MoldMax HH (MM40)和LH (MM30,30HC硬度)均以板材,捧材,及管材的標(biāo)準(zhǔn)尺寸供貨特定尺寸和經(jīng)切鋸后的尺寸可從特約經(jīng)銷商采購。
