Owning a set of tungsten carbide molds is just the beginning. Only careful maintenance can allow it to release powerful energy for a long time and safeguard your production.

Daily cleaning is essential. After each use, be sure to promptly remove any impurities such as metal shavings, plastic particles, and oil from the tungsten carbide mold surface. Even tiny debris can scratch the mold surface over time, affecting precision and mold release. Gently wipe with a soft brush, a dust-free cloth, and a dedicated cleaning agent, paying particular attention to key areas such as the mold cavity, core, and parting surface to keep them pristine.

Lubrication is crucial. Choose a lubricant that’s compatible with the properties of tungsten carbide and regularly lubricate the mold’s moving parts, such as sliders and ejectors, to reduce friction and wear and ensure smooth operation. In high-temperature conditions, use a heat-resistant grease to prevent lubricant failure and component seizure. This is especially critical for die-casting molds, as every smooth opening and closing means increased production efficiency and extended mold life.

Regular inspections are essential. Use high-precision measuring tools, such as a three-dimensional coordinate measuring machine, to periodically check the mold’s dimensional accuracy and monitor for signs of deformation and wear. For stamping molds, focus on edge wear. If blunt edges are detected, arrange for timely repairs to prevent excessive wear and tear that could render the mold useless. For injection molds, monitor changes in cavity dimensions to predict repair opportunities and nip production risks in the bud.

Proper storage. When molds are not used for a short period, they should be coated with anti-rust oil, wrapped in moisture-proof paper, and stored in a dry, well-ventilated environment free of corrosive gases. For long-term storage, they should also be removed regularly for inspection and re-maintenance. This ensures the molds are always ready for the next peak production period, ensuring they are in optimal condition and continue to create value for you. By following these maintenance tips, tungsten carbide molds will become the most solid and durable support for your industrial production.
