upper location supervisory

We can use computer or HMI with  upper location supervisory.With database technology, all the pressure process data save in database include each practically pouring process data. So we can query and analysis all the history process data to improve the process quality so much.

Principle of centrifugal casting

图片
Centrifugal casting is that the liquid metal is injected  to the mold of high-speed rotation.Under the action of centrifugal force, the metal liquid is full of mold.Centrifugal force makes the liquid metal in the radial well with casting and formed a free surface of casting.The centrifugal casting can obtain cylindrical inner hole without core.It is conducive to rule out the gases and inclusions in liquid metal ,which improves the mechanical and physical properties of casting.

Trunnion Type Centrifugal Casting Machines

图片
Trunnion type centrifugal casting machines use a mold or flask that is supported and rotated by four trunnion wheels. These machines are used for producing castings that have lengths longer that their diameter.                          Common castings produced on trunnion type include bushings, bearings, cylinder liners, piston rings, pipe, and steel tubes and sleeves. Our automatic centrifugal casting machine all adopt trunnion type as main engine.

Low-pressure sand casting machine

图片
Low-pressure sand casting machine consists of two pieces: holding furnace and liquid surface pressure control system. The furnace cover of holding furnace is used for work table for sand box. The prepared sand box fixed on the cover of holding furnace directly and then pressure casting. Fluid surface forcing control system adopts the high performance proportional valve +precision pressure sensors，which can examine the pressure of holding furnace and control real-time and closed loop feedback by PID accommodation mode. The system has multi-linear pressure, leakage compensation for holding furnace and leakage compensation for liquid surface. The setting add-pressure craft’s curve can be tracked automatically. High precision control of pressure ensures the low press die casting process stable properties and good consistency.
