A:A: Hollow brick molds with through holes have ventilation holes.
A:Answer: Using bolts to lock the core makes it easy to replace, while welding is cheaper.
A:A: Currently, the mold core is outsourced, and it's difficult to source from suppliers, which significantly increases costs. Based on actual calculations, it's not recommended. (German steel is generally only used for paving bricks.)
A:A: Because the mold core sealing plate requires four bolts, and there isn't enough space. Currently, M12 countersunk bolts are used; smaller bolts are more likely to break.
A:A: a) Pay attention to controlling foreign objects in the material and controlling the particle size of the material. b) Pay attention to mold adjustment before production, and try to center the pressure head and mold frame.
A:A: a) The customer's three-phase voltage/single-phase voltage/frequency, and whether the power cord has a grounding wire. b) Does the customer have their own control power supply? Does the customer have their own temperature sensors? How many are there? If so, please provide the wiring method. Precautions for using the heated mold.
