The Hidden Costs of Neglecting Rust Prevention: Protect Your Industrial Molds with Rust Inhibiting Sprays

Apr 9, 2024, 15:48 PM by The Stoner Molding Solutions Team
At your industrial molding facility, molds are a significant investment. You strive to keep them in optimal condition for as long as possible, ensuring the success and efficiency of your operations. But when moisture, fingerprints, and other corrosive elements come into contact with the bare metal surfaces of your molds, they trigger a chemical reaction that leads to rust. This relentless adversary slowly erodes the metal, compromising its structural integrity and eventually rendering the molds unusable.

1. Premature End of Life for Your Mold

Without using rust inhibiting spray on your industrial molds, you risk significantly shortening their lifespan. Rust, as we mentioned earlier, is a corrosive enemy that slowly eats away at the metal surfaces of your molds, especially if you use carbon steel molds. Over time, this corrosion weakens the structural integrity of the molds, leading to premature failure and rendering them unusable.

Imagine investing in expensive molds for your manufacturing operations, only to have them deteriorate and become ineffective due to rust. This not only results in wasted resources but also disrupts your production schedule and can lead to delays in delivering products to your customers. In some cases, the damage caused by rust may even require complete mold replacement, further adding to the financial burden.

To avoid such unfavorable outcomes, it is crucial to take proactive measures to prevent rust on your mold surfaces. Applying a high-quality rust inhibiting spray creates a protective barrier that prevents moisture and corrosive agents from reaching the metal. This simple step can significantly extend the life of your molds, ensuring their reliability and cost-effectiveness for years to come.

2. Increased Costs

Neglecting rust prevention on your molds can increase costs in several ways. Firstly, as rust corrodes the metal surfaces, it creates uneven and rough textures. These imperfections can affect the quality of your molded products, leading to rejections and wastage. Additionally, molds with rust can cause issues with part release and demolding, resulting in production slowdowns and increased labor costs.

Furthermore, when rust accumulates on your molds, cleaning and maintaining them effectively becomes more challenging. Removing rust can require additional time, effort, and resources to restore the molds to their optimal condition. The costs associated with mold repairs, replacements, and maintenance due to rust-related damage can quickly add up, impacting your bottom line.

By incorporating rust inhibiting sprays into your mold care routine, you can minimize the risk of rust-related costs. This simple preventive measure helps to maintain the smooth operation of your molding processes, reduce rejects, and preserve the longevity of your molds, ultimately saving you money in the long run.

3. Increased Downtime

Whether you mold thermoplastic, polyurethane, composite, or rubber products, rust on your industrial molds can lead to increased downtime in your manufacturing operations. When rust accumulates on the mold surfaces, it can cause sticking or binding, making it challenging to release the molded parts smoothly. You can then experience production delays as you need to spend time troubleshooting and resolving the issues caused by rusty molds.

Moreover, rust can also contaminate the molding process itself. As the rusty particles mix with the molding material, they can create defects and imperfections in the final products. This contamination affects the quality of the parts and requires additional time and resources for inspection, rework, or even scrapping of defective items.

You can prevent these disruptions to your manufacturing operations by utilizing rust inhibiting sprays. The spray's protective barrier ensures smooth part release, minimizing the chances of sticking or binding. This spray helps to maintain consistent production flow, reduce downtime, and increase overall efficiency.

4. Damage to Other Molding Machinery

The effects of rust on your industrial molds can extend beyond the molds themselves. Rust particles can easily transfer to other components and machinery involved in molding, causing damage and compromising their functionality. For example, rusty molds can leave residue on injection molding machines, leading to clogged nozzles or degraded performance.

Additionally, if molds with rust are used in multi-cavity applications, the corrosion can spread to adjacent cavities, affecting multiple parts simultaneously. This can result in a domino effect of defects and failures, requiring extensive troubleshooting and maintenance to resolve.

To protect your entire molding machinery and ensure smooth operations, it is essential to prioritize rust prevention on your molds. By using a rust inhibiting spray, you create a barrier that prevents the spread of corrosion, safeguarding both your molds and other critical equipment involved in the molding process.

5. Molding Issues

Rust on your industrial molds can lead to various molding issues that can significantly impact the quality of your products. One common problem caused by rust is surface imperfections on the molded parts. When rusty molds are used, the corrosion can transfer onto the part's surface, resulting in blemishes, pitting, or rough textures. These defects not only affect the aesthetics of the products but also compromise their functionality and performance.

Furthermore, rust can interfere with the mold's ability to achieve precise and accurate dimensions. As the corrosive particles accumulate, they can cause uneven wear on the mold surfaces, leading to dimensional variations in the molded parts. These defects can result in parts not meeting the required specifications, leading to customer dissatisfaction and potential recalls or returns.

You can avoid these molding issues by taking preventive measures such as using a rust inhibiting spray. The spray's protective barrier helps maintain smooth and clean mold surfaces, ensuring consistent part quality and dimensional accuracy. This barrier ultimately enhances your product's overall value and customer satisfaction.
