20T C-Type Wax Injection Machine for Investment Casting

1,Configuration instructions

  1, electrical components: Chint , PLC programmer for Taiwan Delta series, close switch series components for Omron, Japan.

2,Hydraulic system: the hydraulic valve is Taiwan oil research; the hydraulic motor is Taiwan Group; the hydraulic pump is Taiwan Gree, the circulating motor pump is Taiwan Weiliang; the drum-cylinder seal is Japan NOK; the oil cylinder is Jinan Yuci Branch.

3,The main engine is made of δ 20 hot plate welding, the inner layer of the wax box is 304 stainless steel plate welding, the wax cooling system is made of three pipes, and the wax pipe is welded by pickling.

4. The nozzle diameter of the duplex Wax Injection Machine is Φ8-11mm. The wax injection speed is about 3-8 mL / s

2,Main fatures and advantages
 1.Intelligent PLC controlled, enhance production efficiency and pattern accuracy.
 2.Machine adopts advanced hydraulic design,when pressing large pattern, wax in main reservoir tank can not fully fill the mold, under this situation,auxiliary tank will continue to inject wax into mold till pattern formed. During this process, pressure always above15- 20Mpa, clamping force 30-50t. clamping and injecting pressure and flow are adjustable. Equipment can adapt to different products, increase application scope and adaptability.
 3. After wax injection, pressure preservation, and mold injection process, system will automatically open overflow valve, that means hydraulic oil will return to cooler under standby state, so as to prolong motor service life and enhance hydraulic system reliability and stability. Machine also equipped with platen thermostatic apparatus, which can effectively avoid flow mark for big pattern more than 10kg, and can uniquely improve wax pattern surface quality & dimensions control.
 4.Secondary pressurizing can prevent large and thick pattern from denting. First low-pressure injection achieve quick mold-filling, then changeover to high pressure-injecting to ensure pattern and mold surface contact closely. The pattern will be passed tightly, and contraction effectively controlled.
 5. Injection nozzle automatically adjusted UP/DOWN or IN/OUT.
 6.Fulfill industrial automation, automated wax transfer system can reduce loss & idle during wax treatment process.
