Zinc Casting Idler Side Awning Mount

Zinc Die Casting Idler Side Awning Mount, it is an customized part applied to motor homes, usually zinc Die Casting parts is by hot chamber die casting machine and cold chamber die casting machine, the part have small wall thickness and feature of big cavity, so the part will have large enclosed strength to the core of the mold, so to release the part from the mold will require large ejecting force which is decided by the ejector pins. Under such large ejecting force, the ejector pins will have potential issue of deformation. In this case, it is very important to set up the location of the ejector pins, the qty of the ejector pins reasonably. Meanwhile, in order to ensure the smooth mold release, the part will need more mold release agent, so in the control plan, the engineer request to apply to automatic agent spray. When die casting, the temperature of the molten metal should be in control, the higher temperature of the molten zinc alloy, the higher temperature of the mold will be, then heat and decompose the agent to plenty of water vapour, it probably will be involved in the part through the runner, leading to the bubble on the part appearance.  so another point to pay attention is to choose agent containing less volatile substance, to avoid more air trapped in the part.  In addition, the design of the venting system will cause potential possibility on resulting in the bubbles to the part. 

At last, the demand of this Motor Home Parts are very big, the monthly demand is more than 30000 pieces. In order to enhance the tooling life, in control plan, the engineer requires the supervisor of the die casting workshop to arrange maintenance to the tooling for every 5000 shots or 10000 shots. It will help prolong the timing of running prior to the crack.  In order to ensure the production plan won't be affected, we also have another tool as backup. 

By the way, as this project is wonderful, so we are much more careful during the development of the tooling, prior to the built of the die, we run mold flow analysis to simulate the situation in die casting, to decrease the risk in actual production.
