Hot runner mold has many advantages. It is suitable for big parts. Hot runner mold can improve production efficiency.
It reduces shot volume into runners, which reduces cycle time and help save material cost and production cost.
Hot runner mold needs smaller machines and requires lower injection pressure and lower clamping pressure.
Besides, it could keep a consistent heat within the cavity and better control volume balancing and timing for accurate reproduction of parts.
What’s more, hot runner mold can achieve automated processing and does not need to cut the sprue manually.
Besides that, the hot runner mold has some disadvantages. It’s more expensive and complicated to design and builds.
Hot runner mold has higher maintenance costs and higher initial start-up costs than cold runner molds. It has higher risks of thermal damage.
