Conventional Die Casting and multi slide die casting is cutting-edge die-casting technology，Conventional die casting is more common, multi slide die-casting is a technology that has emerged in recent years, it is fast, high quality, high precision, high consistency, especially suitable for some small size products (less than 500 g). like automotive connector industry, so what is difference between Conventional Die Casting vs Multi Slide? let’s dig in today, keep reading.
Conventional Die Casting
The conventional die casting process, also known as high pressure die casting, consists of four main steps, include die casting mold preparation, filling, injection, and deburring, and they are the basis for various modified die casting process. The preparation process involves spraying lubricant into the mold cavity, which helps control the temperature of the mold in addition to helping to release the casting. The mold is then closed and the molten metal is injected into the mold at high pressure, which ranges from about 10 to 175 MPa.
Once the molten metal is filled, the pressure is maintained until the casting is solidified. The ejector then pushes out all the castings. Since there may be more than one cavity in a mold, multiple castings may be produced per casting process.
The deburring process then requires the separation of slag, including die gates, runners, slags, and flash. This process is usually accomplished by extruding the casting with a special trimming die. Excess mold gates can be reused after melting. The typical yield is about 67%. Pressure casting is a highly effective and efficient method of precision casting. The technology of most die casters in the market today is mainly conventional die casting
Conventional die casting advantage and disadvantage
| Advantage of conventional die casting | Disadvantage of conventional die casting |
| Can produce relatively large products (5g~50kg) | The input is relatively large |
| Mature technology and common application | Tooling fee is more expensive |
| Product surface treatment diversification | Machine Take up a lot of space |
| Stable product quality | Requires much manual labor |
Multi Slide Die Casting
The multi-slide die casting machine is equipped with improved die casting machine mechanics and a unique injection control system to improve the quality and speed of molded products. also improve casting parts flash and burs.
The machine’s unique injection control system have closed-loop and open-loop injection,
Closed-loop control has the advantage of providing optimal parameters for the injection cycle to eliminate the hammering effect, while open-loop has the advantage of being suitable for die-casting small products requiring injection strokes too short to respond in closed-loop control.
it has helped die casters reduce lead times and cut costs by eliminating secondary operations.
In-mold release is the automatic separation of the die casting from the runners and gates at mold opening. Use in-mold release.Subsequent automatic part separation helps feed parts directly from the die casting machine into the automated assembly line.
No manual intervention is required. Closed-loop injection control system provides real-time control of the injection process from start to finish.Resulting in consistent system performance and superior part quality.
Multi Slide Die Casting advantage and disadvantage
| Advantage of Multi slide | Disadvantage of Multi slide |
| High product quality and efficiency | Machine are more expensive |
| High precision, high consistency,Less defective products | The large products can not produce |
| Very short molding cycle（2~7 second per shot) | Currently only available for zinc alloy |
| Small machine footprint | |
| Small investment in tooling | |
| High material utilization |
