The so-called High Pressure Aluminum Die Casting process is actually a comprehensive use of die casting machines, die casting alloys and die casting molds to maintain a stable rhythm to produce castings with good appearance, good quality, size and compliance with the requirements of the agreement.

       High Pressure Aluminum Die Casting Process:

       1. Determine a reasonable production rate and specify the cycle time of each injection cycle.

       Too low productivity is not conducive to improving economic efficiency. Excessive productivity often comes at the expense of die life and casting yield, and the economics of the ledger can be poor.

       2. Determine the correct die casting parameters. The injection speed, injection pressure and alloy temperature should be reduced under the premise of ensuring that the casting meets the customer's quality standards.

       This has the benefit of reducing machine, mold load, breakdowns and service life. According to the characteristics of the die-casting machine, the characteristics of the mold, the characteristics of the castings, and the characteristics of the die-casting aluminum alloy isosceles triangle, determine the rapid injection pressure, the boost pressure, the slow injection stroke, the rapid injection stroke, the punch follow-out distance, the push-out stroke, and the pressure holding time. , reset time, alloy temperature, mold temperature, etc.

       3. Use water-based paint and formulate a strict and detailed spraying process.

       Coating brand, ratio of coating and water, spraying amount (or spraying time) and spraying sequence of each part of the mold, compressed air pressure, distance between spray gun and molding surface, spraying direction and angle of molding surface, etc.

       4. Determine the correct mold cooling scheme according to the actual situation of the die-casting mold.

       The correct mold cooling scheme affects production efficiency, casting quality and mold life. The plan should specify the cooling water opening method, start cooling after several die casting times, and open the cooling water valve to the specified opening degree every few die times. The cooling intensity of the spot cooling cooling system should be adjusted on-site by the High Pressure Aluminum Die Casting process engineer, and the heat balance of the mold can be achieved with spraying.
