How to Prepare and Store Injection Molds for Long-Term Storage

In the plastics manufacturing industry, proper preparation and storage of injection molds are crucial for maintaining their longevity and performance. This blog post will guide you through the essential steps to protect and store your metal molds effectively, ensuring they remain in optimal condition for future use.

Step 1: Thorough Cleaning of the Injection Molds

Before storing your injection molds, it's vital to clean them thoroughly. Use a high-quality mold cleaner like 46910 Injection Mold Cleaner 4 offered by Complete Plastics to remove any residues, contaminants, or debris. This step prevents corrosion and ensures that the mold surfaces are free from any substances that could cause damage over time.

For instance, using a non-corrosive solvent can effectively dissolve any leftover thermoplastic materials. You can also run a soft brush over areas that may have accumulated dust or debris. Make sure to inspect the mold for any signs of wear during this cleaning process.

Step 2: Rust Prevention

After cleaning, apply a rust preventative like 40212 no-rust offered by Complete Plastics to the mold surfaces. Choose a product that is specifically designed for metal molds and offers long-lasting protection. This step is crucial in preventing rust and corrosion, which can compromise the mold's integrity and performance.

For metal molds, consider using rust inhibitors that provide a thin film over the surface. Applying the product evenly with a clean cloth can ensure maximum coverage. This is especially vital if your molds will be stored in environments prone to high humidity or temperature fluctuations.

Step 3: Lubrication

Proper lubrication of the mold components is essential to prevent wear and tear during storage. Use a high-quality mold release agent or grease like 43911 offered by Complete Plastics to lubricate moving parts and ensure they remain in good working condition. This step helps in maintaining the mold's functionality and extends its lifespan.

For example, using a silicone-based lubricant can effectively reduce friction between moving parts. This not only preserves the mold's integrity but also allows for smoother operation when the molds are eventually put back into service.

Step 4: Protective Packaging

Once the mold is cleaned, protected from rust, and lubricated, it's time to package it for storage. Use protective covers or wraps to shield the mold from dust, moisture, and other environmental factors. Ensure that the packaging is secure and provides a barrier against potential contaminants.

Consider using anti-static bubble wrap or vacuum-sealed bags to prevent moisture accumulation. Additionally, placing silica gel packets inside the packaging can help absorb any ambient moisture, further protecting the molds from damage.

Step 5: Controlled Storage Environment

Store the packaged molds in a controlled environment with stable temperature and humidity levels. Avoid areas with extreme temperature fluctuations or high humidity, as these conditions can lead to mold damage. A climate-controlled storage facility is ideal for maintaining the molds in optimal condition.

For maximum effectiveness, monitor the conditions in your storage area using hygrometers and thermometers. This proactive measure can alert you to any potential changes in environment that might compromise the integrity of your molds.
