阿里巴巴Investment mold precision casting enterprises are less, mainly low-temperature precision casting wax, mostly self-adjusting products, Luoyang first tractor factory consumption of more than 100 tons/year.
熔模精密铸造企业较少，以低温精密铸造蜡为主，大多为自调产品，洛阳第一拖拉机厂用量100多吨/年。
Most of the moulds used in investment moulds in China are paraffin-stearic acid low-temperature moulds made by investment moulds.
我国大部分熔模铸造厂使用的模料是熔模铸造厂自制的石蜡——硬脂酸低温模料。
Its low quality, high cost, and seriously affect the improvement of casting quality, the production of castings in the international market competitiveness is small.
其质量低、成本高，且严重影响铸件质量的提高，所生产的铸件在国际市场上竞争力小。
However, many investment casting plants in China want to produce castings for export.
然而，我国许多熔模铸造生产厂希望生产的铸件用于出口。
To export castings, we must improve the quality of castings.
铸件要出口，就要提高铸件产品质量。
Therefore, on the one hand, advanced investment casting equipment is required, and on the other hand, high-quality mold materials are required.
因此，一方面需要先进的熔模铸造设备，另一方面需要高质量的模料。
Obviously, the self-sufficient mold production method of investment casting production plant is difficult to produce high-quality mold, so this situation is contradictory to modern large-scale production.
显然，熔模铸造生产厂自给自足式的模料生产办法是很难生产出高质量的模料，因而此状况与现代化的大生产相矛盾。
In recent years, China has introduced a lot of modern investment casting equipment and high-quality mold materials, and with the increasing exchanges with overseas, the varieties and specifications of imported mold materials are increasing.
近年来，我国引进了许多现代化的熔模精铸设备和高质量的模料，而且随着与海外的往来与日俱增，进口模料品种、规格日益增多。
It can be seen that the production of mould materials in China is faced with difficult tasks and challenges such as improving the quality of mould products and expanding the variety of mould materials.
由此可见，我国模料的生产面临着改进模料产品质量和扩大模料品种等艰巨任务与挑战。
