What are the main factors that determine the selection of a suitable die-casting machine? Today's Liansheng Large die-casting machine The manufacturer will briefly share with you:

The selection of a suitable die-casting machine mainly depends on the following factors:

1. Weight of die-casting parts: die-casting machine can be selected according to the weight of die-casting parts. Different die-casting parts need different die-casting machines.

2. Material of die-casting machine: die-casting machine can be selected according to the required die-casting material. Common die castings are copper, aluminum, magnesium, zinc, lead, tin and other alloys. Die casting machine can cast different materials.

3. Die casting size: die-casting machine can be selected according to the size of die-casting products. Die casting machine clamping force=large projection area/injection volume.

4. Precision and internal quality of die-casting parts: It is important to select die-casting machine according to the performance of injection system. The injection system has four main parameters: injection force: the driving force of the injection piston movement. You need to know the diameter of the injection cylinder, and then calculate the injection tonnage you need; Start time of pressurization: the time from the stop of punch movement to the start of pressurization during idling shall be less than 0.02s; Pressure building time: the time for the pressure to reach the set value should also be less than 0.02s; Pressurization time: the sum of pressurization start time and pressure establishment time is the pressurization time, which should be less than 0.04s.

Zinc aluminum alloy Die-casting machine What are the advantages of? Zinc aluminum alloy die-casting machine can produce metal parts with disordered shape, clear outline, thin wall and deep cavity; Due to the high fluidity of molten metal under high pressure and high speed, metal parts that are difficult to be processed by other processing methods can be obtained. The dimensional accuracy of die castings is relatively high, up to IT11-13, sometimes up to IT9, and the surface roughness reaches Ra0.8~3.2um, with good interchangeability.
