2. Die-casting working temperature During the die-casting production process, the effect of the die-casting working temperature being too high or too low on the quality of the casting is similar to the casting temperature of the alloy. It can affect the life of the die-casting type and the normal production. Therefore, the temperature of the die-casting type should be controlled during the production process to maintain it within a certain range. This temperature range is the working temperature of Mpɛn pii no, die casting type., wɔ adeyɛ a ɛkɔ so no mu no, sɛ ɔhyew a ɛwɔ die-casting type a ɛtwe nsu no mu no yɛ kɛse sen ɔhyew dodow a ɛyera wɔ nneɛma a atwa ho ahyia no mu a, ɔhyew no bɛkɔ soro bere nyinaa, na mframa anaasɛ nsu a ɛma onwini a ɛkyinkyini (nsu anaa ngo) no betumi adi dwuma de ayɛ nwini.
