Materials which can be coated 可涂層材料

　　High-speed tool steels, hot and cold processed steels, rust-resistant steels, annealed steels and carbides.

　　高速鋼椒玖，熱作鋼冷作鋼仙茴，不銹鋼，退火鋼和硬質(zhì)合金妖奕。

Heat treatment 熱處理要求

　　Heat treatment must be carried out in such a manner that the coating temperature(250°C—up to 500°C) does not result in loss of hardness, not any change to the geometry or dimensions of the item. The hardness of the tools to be coated should not be less than that of uncoated tools.

　　熱處理溫度必須高于涂層溫度（250°C到 500°C以上 ）遭唠，以免造成硬度降低，形狀或者尺寸發(fā)生改變窄栓。涂層的工具硬度要高于不涂層的工具硬度颊姻。

Make-Up of the tools 模具結(jié)構(gòu)

　　In order for the tool to be held, there must be holes, a thread or a surface which can remain uncoated. Surface which must not be coated should be capable of being covered by a mechanical, or physical mask.

　　為了裝卡需要，模具上需要有孔笙亿，螺紋或者允許不涂層的面矫恳。要求不能涂層的面需要能用機(jī)械或者物理的方法遮蓋。

　　Tools with internal contours (drilled holes; slots; etc.) can be coated. Depending on the geometry, the coating thickness will diminish as their depth increases.

　　模具的內(nèi)部輪廓（孔炕烈，槽等）也可以涂層臊啃。涂層的厚度會(huì)隨著深度增加而減小。

　　Soldered and welded areas must resist temperatures of up to 600°C and must be free from air-bubbles, flux and cadmium. It should be noted that, during the coating process, which takes place over several hours in vacuum and involves temperatures of 400°to 500°C, the strength of the soldered and welded areas will reduce. This also applies to solders which can be used under vacuum. Tools which have been repaired by welding must have been annealed under stress-free conditions.

　　焊接區(qū)域須能承受600度以上的高溫拆内，不能有氣泡旋圆，焊劑和鎘。需要注意的是在幾個(gè)小時(shí)的真空和四五百度高溫的涂層過程中麸恍，焊接區(qū)域的強(qiáng)度會(huì)降低灵巧。這同樣適用于真空環(huán)境下的焊接。補(bǔ)焊的模具需要進(jìn)行無應(yīng)力退火抹沪。

　　Tools must not be clamped, glued or compressed. Blind holes and internal threads must be free from hardening salts and other forms of contamination. Cooling/tempering channels and runners must be open and clean.

　　模具不能夾住刻肄，膠合或壓住。盲孔和內(nèi)螺紋內(nèi)不能留有淬火鹽或其它形式的臟物融欧。冷卻水道和流道必須打開干凈敏弃。

Surface condition of tools 模具表面狀況

　　The surfaces must be flat and smooth to bare metal. Ground surfaces must be free from burnished damage . Cutting edges must be free from burrs. Spark-eroded surfaces should be achieved in fine finish mode and oxide layer should be removed. Surfaces must be free from swarf, wax, adhesive strip, paint, residues from chemical smelting, etc.

　　 模具表面應(yīng)平坦光滑。磨削表面不能有燒傷噪馏。刃口不能有毛刺麦到。放電面應(yīng)該精加工并去處氧化層。模具表面不能有塑膠屑欠肾，臘瓶颠，膠帶，油漆椭吠，化學(xué)殘留等捅青。

Delivery method, packaging 包裝及運(yùn)輸

　　Tools must be packed so that they cannot be damaged by external forces, or by striking against each other.The packing must also be suitable for use for the return of the tools. To protect against rust, the tools should be lightly coated with a water-repellent oil.

　　模具的包裝應(yīng)能避免受外力損壞或相互碰撞。包裝還要能重復(fù)使用炬锦。模具需要防銹豺孤。
