Mineral casting by EPUCRET

EPUCRET mineral casting is a future-oriented material. As a construction component for machine frames, mineral casting has been taking place of cast iron due to its performance and price advantage. On the basis of leading technology and over 20 years experience, EPUCRET mineral casting has been introduced in industries e.g. machine tool, medical, semiconductor etc.

Complex structure feasibility and integration

As process and performance varies from traditional cast iron’s, EPUCRET mineral casting can be cast in complex structure that cast iron can not. Special bonding can get more complex structure, resulting in ideal form.
With excellent performance of integration, mineral casting can be cast in cutting emulsion pipes, containers, steel rails, wires, connectors etc. For example, guideway can be cast in mineral casting, and be milled and grinded after forming. EPUCRET mineral casting can be adjusted thermal expansion coefficient according to specific condition; it can strongly integrate with materials such as steel, plastic etc. As excellent integration leads to eliminating process of assembly and machining, customers will save plenty of time, which greatly improve productivity and economical benefit.

High precision

The final precision of mineral casting is much higher than cast iron once moulding. With respect to traditional cast iron, large contraction will occur. However contraction will hardly occur in mineral casting. Mineral casting process can achieve final form without machining, due to the high final accuracy. If necessary, milling and grinding makes mineral casting much high precision.

Vibration damping

Under the condition of high dynamic, EPUCRET mineral casting presents excellent vibration damping.  EPUCRET mineral casting achieves up to 10 times better value of vibration damping than cast iron. Vibration caused by motor or fork lift will hardly affect mineral casting. During process, external vibration will hardly affect machine bed made of EPUCRET mineral casting, which ensures machine tool accuracy and extends service life for machine tool.

Thermal stability

With the sensitive performance to temperature, traditional cast iron will freely deform by temperature change. With respect to EPUCRET mineral casting, thermal conductivity and coefficient is controlled effectively. The geometry change caused by heat will be minimized, machine tool accuracy is thereby ensured.

Anti-corrosion

EPUCRET mineral casting is strongly resistant to cutting fluid, coolant. With corrosion resistance, container can be reserved in mineral casting for liquid. The container assembly process will be eliminated for customer, which will improve productivity and economical benefit.

At present, developed countries like west Europe and Japan have been using EPUCRET mineral casting instead of traditional cast iron. With over 20 years experience, EPUCRET has established its own system for technology and service. The product, just introduced in China with its price advantage to cast iron, will be favored by customers increasingly.
