How DONGXINDA’s Cold Runner Molds Help Reduce Waste and Production Costs

n injection molding, the runner system plays a vital role in how molten plastic flows into the mold cavity. While hot runner systems are common in high-end applications, cold runner molds remain the go-to solution for many manufacturers focused on cost-efficiency and flexibility.

At DONGXINDA Mold Technology, we specialize in customized cold runner mold solutions that offer a perfect balance of precision, material control, and affordability.

Advantages of Cold Runner Molds

✅ Lower Upfront Tooling Costs
Cold runner molds are less complex and cheaper to manufacture, making them ideal for new product development or small-to-medium production volumes.

✅ Fewer Maintenance Requirements
No heated manifold means fewer components to monitor and repair, minimizing downtime.

✅ Material Versatility
Cold runners support a wide variety of thermoplastics, including engineering resins and recycled materials.

✅ Easier Color Changes
Color and material changes are simpler and faster without residue from heated channels.

Cold Runner vs. Hot Runner: Which Should You Choose?

While hot runners reduce waste, they cost more and require precise temperature control. If your project prioritizes flexibility, lower initial costs, and ease of use, cold runner molds from DONGXINDA may be your most strategic option.
