ColdRunnerSysteme

ColdRunnerSysteme is a company that specializes in cold runner systems for injection molding. The firm designs, manufactures, and supplies tooling components and complete systems that keep the runner path within the mold cavity and solidified with the molded part, allowing the runners to be separated and recycled after ejection. This approach is contrasted with hot runner systems, which keep the plastic molten in heated channels.

Its product line includes cold runner plates and manifolds, gate inserts, sprue bushes, cooling channel configurations, and integration with automation for part removal and runner collection. The systems are designed to be modular, enabling customization for different part geometries and production volumes. Materials compatibility covers common thermoplastic resins used in automotive, consumer goods, and packaging applications.

Industry use cases emphasize waste reduction, recycled material handling, and potential reductions in tooling complexity and maintenance. However, cold runner technology can involve higher material costs if runners are discarded rather than efficiently recycled, and cycle times may be influenced by runner design and cooling.

ColdRunnerSysteme operates within the broader plastics processing equipment sector and competes with providers of hot runner and hybrid systems. Decisions about adopting cold runner solutions depend on part size, mold complexity, waste-management strategies, and total cost of ownership. The company positions itself as a supplier of turnkey tooling and modular components to injection molding operations.
