非特新^®EC85 ^TM系列陶芯是一种功能结构陶瓷制品，设计用于精密铸造铸件中，作为形成铸件空腔的转接体，或者形成铸件的内腔结构的模具。使用中陶瓷型芯与外部型模及模壳一起共同保证铸件对空腔的尺寸精度要求。

陶瓷型芯广泛用于形成复杂形状或不易成形的铸件型腔，作为简化工艺难度降低成本提高制品合格率的一种特殊的工艺手段。

产品特点

◎强度高，足够承受射蜡及其它处理工艺所需求的强度；
◎有足够的耐火度，适用于铸铝、铸铁、铸钢和各种高温合金材料的精密铸造。
◎化学稳定性好，高温下不与铸件的金属熔液（铁水或钢水）发生化学反应。
◎热膨胀系数低，保证铸件空腔的精度；
◎易成型，可以制造形状复杂的陶芯，适应各种复杂空腔的铸件要求，可以解决任何内部孔槽的问题。
◎尺寸精度高，尺寸公差一般为±0.5％，特殊尺寸可达±0.2～0.3％。
◎陶芯表面细腻光滑，采用陶芯形成的铸件型腔的表面光洁度是普通型砂铸件的无法比拟的。

◎定制化生产，满足客户的个性化需求

EC85^TM Ceramic Core for Investment Casting

EC85 ^TMCeramic Core is a kind of cavity transferring tool inside mould. It is characterized by high strength and refractoriness and superior thermal stability that enable EC85^TM ceramic core can bear attack from wax injection and extreme thermal shock during shell firing and casting pouring. With excellent high temperature stability and core leachability, EC85^TM Ceramic Core is widely used as processing tool for castings with open and blind passages forming.

Specification of EC85 ^TM Ceramic Core

◎ High strength to bear attack from wax injection and other processing treatment.

◎Enough refractoriness, it is suitable for Aluminum, iron and steel casting.

◎No reaction with metal liquid in high temperature.

◎ Low thermal expansion coefficient to ensure the accuracy of casting cavity.

◎ It is ideal tool to solve any cavity with complicated shape inside casting.

◎ Accurate dimension, general tolerance is ±0.5%，It can be up to ±0.2～0.3％ if required.

◎Surface Flatness, It can reach to 10 times comparing with that of  sanding casting.

◎Customer design is available on order.
