Thixomolding Magnesium Components as Easy as Plastic Injection Molding
The thixomolding process uses magnesium alloy chips as raw materials. By conveying and cutting chips through the reciprocating screw and heating by the barrel simultaneously, the chips gradually become a semi-solid slurry that remains at the front end of the screw. When there is enough slurry stored at the front end, the screw is injected forward and the semi-solid slurry is injected into the closed mold cavity to form. Combines with die-casting and injection molding techniques, the mold and molding material of thixomolding is similar to the die-casting processes, while its injection processes are close to plastic injection molding.

Application Highlights

More complex products can be formed

Higher injection pressure and acceleration performance.

High-precision thixomolded parts with superior surface quality

The measurement, speed, pressure, temperature, etc., could all be controlled in the molding process precisely.

Durable and resistant to deformation

Molding temperature is 50–70 °C lower than die casting, and die life is two times longer.

Thrinkage free and safer without contact to the atmosphere

The magnesium alloy slurry is in a completely closed environment, the temperature of the semi-solid slurry is lower, and less melting magnesium alloy in the barrel.

More eco-friendly

Remove the use of SF6 as protection gas.

Screw barrel unit

Special high-temperature resistant steel and heat treatment process, the screw barrel unit can withstand up to 650℃ and up to 400,000 shots.

Infrared heater

Utilizes an infrared heater for molten material, quick heating, effective heat preservation, and long lifetime.

High-speed fast-response servo valve

Big diameter high-speed servo valve controls the oil inlet opening for fast response and strong acceleration of the injection piston (up to 200m/s²).

Control system

With a 10.4 inch touch screen for simple operation and a scanning time is only 0.4 ms, high-speed control can be easily achieved.

Ultra-high-speed injection control technology

High-speed injection performance achieved through high speed/response servo valve control. The strong acceleration performance of injection piston is up to 200m/s², maximum injection speed up to 5m/s. High-speed control can be easily accomplished using a 10.4 inch touch screen for simple operation and the scanning time is just 0.4 ms. The modular design of the control system enables simple functional expansion and equips it with the standard configuration of the Ethernet interface, allowing it to communicate with peripherals and the accompanying management software. A real-time monitoring system would allow for quick viewing of the machine's parameters. Molding accuracy and stability at a glance, statistics on actual production parameters, the open mold end position deviation is up to 0.1mm and an injection end position variation 0.4mm, and steady performance are all provided by the multi-mode curve overlap display function.
