1. Preparatorywork before the die casting machine installed on the mold: Adjust the positionof wall plate ejector according to the size of the rear roof, ensuring that theejector pin parallels( If not, the ejector will be broken and scuffed), andkeep the working surface clean.

2. Moldmust be compressed after installation, to avoid loosening in the production andresulting in drawing die.

3.Connect the cooling water and turn it on before production. All active partsshould be filled with oil to keep the parts lubricated; The ejector pin shouldbe of medium length to ensure that the product can be successfully removed. Thelength can’t be too long, or the ejector will be scuffed and broken because ofoverload. Check the plunger, making sure it’s not too long.
