Die-casting machine is the key equipment of die-casting production, and its performance determines the quality of die-casting parts objectively. The correct choice of die casting machine is crucial to ensuring product quality, improving production efficiency, reducing production costs and ensuring production safety. The performance of the die casting machine mainly depends on the following two aspects:
Sufficient clamping force: It helps to prevent burrs from appearing when the metal melt pressure is at the highest peak, and at the same time has the resistance to breakage to avoid flying materials during die casting. "Zhuzun" die casting machine specially designed five The point double-hinge clamping structure has sufficient clamping force. For example, when the %&” machine only uses the system pressure of ‘#( in the national technical supervision and spot check, the measured clamping force reaches ")#$&*. sufficient clamping force.
Sufficient injection capacity: to ensure that die casting will not cause overheating of the mold or a large amount of overflow, and at the same time to ensure that the machine has sufficient capacity to deliver enough molten metal and fill the mold with the required high ingest speed in a short time. cavity. The maximum air injection speed of "Zhuzun" die-casting machine is ,-./, and the injection ratio is large, which can die-cast any required zinc alloy products.
Advanced functions, easy operation, reasonable price and complete specifications are the characteristics of "excellent" die-casting machines. After choosing a die-casting machine brand that can meet the needs, it is particularly important to choose a die-casting machine with appropriate specifications. On the one hand, it can be selected according to the size, weight and complexity of the shape of the product (whether core pulling is required); system) to calculate the bulging force to select a die-casting machine with a slightly larger clamping force. Some small die-casting parts, such as buttons, pouch hooks, zipper pullers and lighter accessories, can be made into multiple molds in one mold; another example is the combination mold used by some customers for watch case production, and CM55 is used for one mold with four sets of combination molds Or CM88 die-casting machine is the most suitable, instead of using large-sized machines with small molds and small products. It cannot be unilaterally considered that a machine with a large tonnage (large clamping force) means high pressure. On the contrary, the small area of ​​the mold will cause the pressure to concentrate in the middle of the large template, causing damage to the die-casting machine template and mold, and also causing waste of resources, which does not meet the requirements of environmental protection.
