Q2: How do internal cores affect hollow block production?
A: Molds do not just determine the outer shape. The internal cores create the hollow cavities. You can choose between two-hole or three-hole designs. Well-designed cores allow the concrete to slide out smoothly during demolding. This prevents cracks and saves raw materials.
Q3: Can I customize my block machine mold for specific projects?
A: Yes, your mold must match your specific brick machine model perfectly. Therefore, suppliers like Drax Mold offer full customization. You can adjust wall thickness and taper angles according to your local building codes.
