Die Casting Machine

 
Description of die casting machine:
There are two kinds: hot chamber die casting machine and cold chamber die casting machine, for different zinc and aluminum casting purpose.

Main features of  hot chamber die casting machine:
-- Nozzle, gooseneck and melting pot are especially durable since they are made of hot-work iron or steel.
-- Nozzle and goose neck are heated by electric heater, safety and durable. This keeps temperature steady and avoids jamming of nozzle resulting defective products.
-- Auto central lubricating system, directly setting up times of toggle turning lubrication.
-- Using hydraulic parts imported from famous manufacturers in the world.
-- Special double proportional control system; Using two sets of flux/pressure proportion valves separately, thus making the speed of every actions and pressure to be adjusted freely.
-- Electronic firing oil burner is from Japan. The adjustment of fire is stable and in high safety.
-- Water-cooling type oil cooler with high cooling efficiency to keep certain oil temperature and viscidity.

Note: Special requirements can be satisfied.

Main features of cold chamber die casting machine:
-- Adopts triple-tension-rod or C-shape-bracket plus hydraulic elevator device, thus satisfy requirements of moulds.
-- The injecting system adopts separate dual-speed piston and pressure-charge accumulator, and so it can supply high efficient dual-speed injecting speed and pressure increase.
-- The injecting system is equipped with large-diameter logic valve and precise flux-control valve, thus improves injecting reaction and decreases oil pressure vibration. The system also provides precise 4-stage injecting adjustment.
-- Adopts high performance, low noise twin-link pump, saves energy consumption and improves productivity.
-- Adopts automatic centralizing lubricating system. The lubricating frequency can be pre-set directly and so improves machine life.
-- Adopts motor-driven gear system for changing moulds, simple operation, intelligent automatic mould adjusting program, precise calculation of mould locations.
-- Hydraulic ejector is convenient for control. The ejecting speed is adjustable.
-- Hydraulic system adopts dual-proportion control for convenient adjusting pressure and speed of every part.
-- Adopts precise PLC control, with 100 storage units,auto diagnosing and alarming; Mould fixing position is inspected by high precise electro-ruler, position control accuracy can be 0.1mm.
