Q1: Are Cold Runner Molds Suitable for Large-Scale Production?
A1: They are more suitable for small and medium-sized batches. For large-scale production, hot runner molds are recommended.
Q2: Can waste materials be recycled?
A2: Yes, the gate material can be re-pelletized and reused.
Q3: What is the mold lifespan?
A3: Generally 300,000–500,000 molds, depending on the steel material and maintenance.
Q4: Does it affect the appearance?
A4: Gate marks may be present, but these can be minimized through design.
