模具鋼廠在生產(chǎn)模具鋼時(shí)，需要根據(jù)不同的模具來使用合適的鋼材。其中塑膠模具鋼的使用較為頻繁。一般情況下塑膠模具在制造過程中，需要花費(fèi)極多成本進(jìn)行加工和拋光，因此模具鋼廠在選用模具的材料時(shí)，應(yīng)當(dāng)在保證模具使用性能要求的基礎(chǔ)上，盡量的提高模具鋼的可加工性。那么，塑膠模具鋼如何選材呢？1、根據(jù)塑膠制品的種類選用 </p> <p> 不同的塑膠制品的質(zhì)量和加工方法不同，因此模具鋼廠可以根據(jù)塑料制品的質(zhì)量和加工方法的不同來選用適合的模具鋼，使得模具鋼在保證成本的同事，又具備可加工性。2、根據(jù)塑膠制品的大小和精度選用 </p> <p> 不同的塑膠制品的大小，精度等不盡相同，模具鋼廠可以根據(jù)塑膠制品不同的尺寸和精度的要求來進(jìn)行模具鋼的選用，對一些精度高，生產(chǎn)量大的塑膠制品，可以使用預(yù)硬化鋼材，可以有效的防止熱處理時(shí)模具鋼出現(xiàn)變形的可能。3、根據(jù)塑膠制品的復(fù)雜程度選用 </p> <p> 塑膠制品有些結(jié)構(gòu)比較簡單，有些則相對較為復(fù)雜，那些相對復(fù)雜一些的塑膠制品，其加工工藝也會相對復(fù)雜一些，國內(nèi)**的模具鋼廠一般可以提前預(yù)見到產(chǎn)品需要經(jīng)歷的復(fù)雜程度，因此可以根據(jù)難易程度，選用具有易切削、熱處理時(shí)不易變形、耐磨性高等特質(zhì)的模具鋼來生產(chǎn)。 </p> <p>

模具鋼深冷處理工藝是怎樣的？深冷處理的作用性非常大，近期有很多客戶來咨詢模具鋼深冷處理工藝，模具鋼深冷處理溫度等等之類的問題，天成模具小編在這里為大家詳細(xì)解答下，模具鋼深冷處理工藝是怎樣的。模具鋼深冷處理一般在零下196℃進(jìn)行。DC53模具鋼板材深冷正常的處理工藝如下：一般在淬火和回火工序之間進(jìn)行，也能在淬火回火之后進(jìn)行深冷處理。但是有一種情況要注意，如果在淬火、回火后鋼中仍保留有殘余奧氏體，則在深冷處理后仍需要再進(jìn)行一次回火。深冷處理能提高鋼的耐磨性和抗回火穩(wěn)定性。深冷處理不僅用于冷作模具，也可用于熱作模具和硬質(zhì)合金。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 塑料模具鋼包括熱塑性塑料模具和熱固性塑料模具。美國是較早在工具鋼中列出塑料模具**鋼的國家，塑料模具用鋼要求具有一定的強(qiáng)度、硬度、耐磨性、熱穩(wěn)定性和耐蝕性等性能。此外，還要求具有良好的工藝性，如熱處理變形小、加工性能好、耐蝕性好、研磨和拋光性能好、補(bǔ)焊性能好、粗糙度高、導(dǎo)熱性好和工作條件尺寸和形狀穩(wěn)定等。一般情況下，注射成形或擠壓成形模具可選用熱作模具鋼；熱固性成形和要求高耐磨、**度的模具可選用冷作模具鋼。

熱作模具鋼在工作時(shí)承受著很大的沖擊力，模腔和高溫金屬接觸，反復(fù)地加熱和冷卻，其使用條件極其惡劣。為了滿足熱作模具的使用要求，熱作模具鋼應(yīng)具備下列基本特性： </p> <p> (1)高的熱穩(wěn)定性。熱穩(wěn)定性是指鋼材在高溫下可長時(shí)間保持其常溫力學(xué)性能的能力。熱作模具工作時(shí)，接觸的是熾熱的金屬，甚至是液態(tài)金屬，所以模具表面溫度很高，一般為400～700℃。這就要求熱作模具鋼在高溫下不發(fā)生熱化，具有高的熱穩(wěn)定性，否則模具就會發(fā)生塑性變形，造成堆塌而失效。 </p> <p> <br /> </p> <p> (2)優(yōu)良的耐熱疲勞性，熱作模具的工作特點(diǎn)是反復(fù)受熱受冷，模具一時(shí)受熱膨脹，一時(shí)又冷卻收縮，形成很大的熱應(yīng)力，而且這種熱應(yīng)力是方向相反，交替產(chǎn)生的。在反復(fù)熱應(yīng)力作用下，模具表面會形成網(wǎng)狀裂紋(龜裂)，這種現(xiàn)象稱為熱疲勞，模具因熱疲勞而過早地?cái)嗔?，是熱作模具失效的主要原因之一。所以熱作模具鋼必須要有良好的熱疲勞性?</p> <p> (3)較高的高溫強(qiáng)度和良好的韌性。熱作模具，尤其是熱鍛模，工作時(shí)承受很大的沖擊力，而且沖擊頻率很高，如果模具沒有高的強(qiáng)度和良好的韌性，就容易開裂。 </p> <p> <br /> </p> <p> <br /> 無錫鐵島模具鋼材有限公司生產(chǎn)的模具鋼物美價(jià)優(yōu)，期待您的光臨！銅陵NAK80模具鋼</p><p

熱軋模具由于在有溫度的條件下工作，要求材料具有熱強(qiáng)性和熱耐磨性，為了保證模具的使用壽命模具要冷卻，熱冷交替模具會出現(xiàn)龜裂，即熱疲勞裂紋，所以材料又要求有抗裂紋能力和抗熱疲勞性能。 </p> <p> 按熱強(qiáng)性排列的主系列進(jìn)行選材: </p> <p> 低合金調(diào)質(zhì)模具鋼（6G，6F2，6F3）→中鉻熱作模具鋼（H11、H12、H13）→鎢熱作模具鋼（H21，H22）。 </p> <p> 非標(biāo)準(zhǔn)的熱作模具鋼：例如熱鐓鍛模具用時(shí)效硬化型的6H4。使用H11、H12、H13出現(xiàn)了不能滿足熱耐磨性時(shí)，可以選擇6H1，6H2。 </p> <p> 當(dāng)要求模具以熱作耐磨性為主時(shí)，可以選擇D2，D4→M2，M4→粉末鋼。鋼結(jié)硬質(zhì)合金、鈷基硬質(zhì)合金的高溫耐磨性是很高的，但其熱疲勞性（即冷熱抗疲勞裂紋）很差，不能在急冷急熱狀態(tài)下使用。 </p> <p> <br /> </p> <p> <br /> 鹽城cr12模具鋼</p><p
