Periscopic Shafts Repair utilizing Brush Plating

Recently, our team at Sterling Impreglon Asia was called upon for an urgent repair job on a set of periscopic shafts that had suffered severe damage due to corrosion pitting. The damage was so extensive that it had begun to affect the operational capability and efficiency of our client’s equipment. Time was critical as the customer could not afford prolonged downtime while waiting for a new replacement part. This is where our proprietary Brush Plating process became the ideal solution for fast and efficient repair.


Step 1: Damage Assessment and Preparation
We dispatched a team of seasoned technicians to the site to survey the extent of the damage. By carefully examining the corrosion pitting on the shafts, we were able to determine the best course of action. To prepare the damaged areas for plating, our technicians widened (but did not deepen) the corroded areas, ensuring that the surface was optimal for a successful repair.


Step 2: Masking and Cleaning
Once the damaged sections were prepared, we carefully masked the surrounding areas to prevent any chemical leakage during the Brush Plating process. A thorough cleaning of the pitted surfaces followed, ensuring that all dirt, oil, and impurities were removed. This step is crucial for the adhesion of the plating material.


Step 3: Rebuilding the Damaged Areas with Brush Plating
We then applied our proprietary Brush Plating technology, beginning with a layer of copper to rebuild the corroded areas. The copper plating restored the damaged sections back to their original dimensions, allowing the shafts to regain structural integrity.


Step 4: Finishing and Quality Assurance
Once the copper was applied, we carefully ground down the plated areas to ensure they were level with the rest of the shaft. A final layer of nickel was added to cap off the repair, providing enhanced durability and protection. This nickel layer ensures that the shaft is restored to a condition that is as good as new.

To complete the job, we conducted a dimensional check to verify that the repaired shafts were within the tolerance range requested by the customer, ensuring their optimal performance.

In the printing industry, quality is everything. Whether producing packaging materials, labels, newspapers, or commercial print products, even the smallest defect can affect the final output. One commonly overlooked issue that can significantly impact printing performance is damage to printing cylinders, particularly corrosion and scorelines . While these issues may initially seem minor, they can gradually lead to poor print quality, increased material waste, production downtime, and higher operational costs . Understanding how corrosion and scorelines affect printing performance is the first step towards preventing bigger problems. What Causes Corrosion and Scorelines on Printing Cylinders? Printing cylinders are constantly exposed to demanding operating conditions. Overtime, wear and environmental factors can damage the cylinder surface. Common Causes of Corrosion: Moisture exposure Chemical reactions from inks and cleaning agents Humidity and poor storage conditions Breakdown of protective surfaces over time Common Causes of Scorelines: Foreign particles trapped during operation Improper handling or cleaning Mechanical wear and friction Contact damage from surrounding components These problems often develop gradually and may go unnoticed until print quality begins to suffer. How Corrosion Affects Printing Quality Corrosion creates localized pitting and uneven surfaces on printing cylinders. When the cylinder surface is no longer smooth, several problems may occur: 1. Uneven Ink Transfer Damaged surfaces prevent proper ink distribution, leading to: ❌ Patchy or inconsistent print quality ❌ Uneven color density ❌ Poor image clarity 2. Defects in Finished Products Corrosion pits can create visible imperfections such as: ❌ Marks or blemishes on printed materials ❌ Distorted print patterns ❌ Reduced product quality This becomes especially critical in industries where visual quality is essential, such as packaging and branding. 3. Increased Material Waste Poor print consistency often means: ❌ Higher rejection rates ❌ More wasted material ❌ Increased production costs Overtime, even small defects can significantly affect profitability. How Scorelines Affect Printing Performance Scorelines are grooves or scratches on the cylinder surface that directly affect precision. Common Problems Caused by Scorelines: 1. Print Distortion Scorelines can interrupt smooth cylinder contact, causing: ❌ Streak marks ❌ Blurred sections ❌ Inconsistent printing results 2. Reduced Printing Accuracy In high-precision printing applications, even slight surface damage can affect registration and alignment. The result? ❌ Lower print consistency ❌ Customer complaints ❌ Reduced product confidence 3. Unexpected Downtime If left untreated, damaged cylinders may eventually require urgent repairs or replacement interrupting production schedules. For printing companies, downtime means: ❌ Delayed deliveries ❌ Missed production targets ❌ Increased operational pressure Can Damaged Printing Cylinders Be Repaired? The good news is YES . In many cases, corroded or scored printing cylinders can be restored instead of replaced. At Sterling Impreglon Asia, we utilize our proprietary Brush Plating Technology to repair damaged cylinder surfaces with precision. The process allows us to: ✔ Restore corrosion pitting and scorelines ✔ Rebuild damaged surfaces to required dimensions ✔ Improve cylinder functionality and surface consistency ✔ Extend the lifespan of expensive mechanical components Most importantly, repair often proves to be faster and more cost-effective than replacement . Why Early Repair Matters Addressing corrosion and scorelines early helps printing companies: ✔ Maintain consistent print quality ✔ Reduce material wastage ✔ Avoid costly downtime ✔ Extend equipment lifespan ✔ Improve production efficiency A small repair today can prevent a much larger problem tomorrow. Final Thought Corrosion and scorelines may start as small imperfections but their impact on printing quality can be significant. For printing companies focused on quality, efficiency, and operational reliability, maintaining cylinder condition is critical. At Sterling Impreglon Asia, we help customers restore damaged printing cylinders with precision, durability, and minimal disruption , ensuring production stays smooth and print quality remains consistent. 👉 Facing corrosion or scorelines on your printing cylinders? Contact Sterling Impreglon Asia today to learn how our repair solutions can help restore performance and reduce costly downtime.
