Expert Guide: Common Failures & Maintenance of Tinplate Can Components
Common Failures and Maintenance Methods of Tinplate Can Components, Explained by the Manufacturer. As a manufacturer of tinplate can components, we have invested in the R&D and production of can-making parts for years. We understand that the quality of tinplate can components is directly related to the forming performance, sealing reliability and lifespan of finished tin cans. In cooperation with downstream can-making manufacturers, we have summarized these common failure modes of components in industrial production, proposing measures for maintenance to help enterprises reduce mechanical loss and improve production efficiency. Tinplate can components include can lids, can bottoms, can body stampings, sealing parts and other main accessories. With the impact of high-speed automation of can-making lines, continuous high-load operation leads to all kinds of problem of wearfailure. Deformation and cracking is among failure. This type of fault is usually induced by the fluctuation of internal stress of the raw material, inaccurate stamping dies, or intentional physical squeeze during transport and installation. Deformed components will lead to poor sealing of the can body, resulting in leakage and air penetration. Sealing failure is a critical defect for the food and daily chemical packing industry. The aging and abrasion of sealing components will invalidate its sealing function directly.This failure is typically linked with prolonged exposure to acids and alkalis, mismatched sealing materials, and variations in temperature and humidity in production environments, which result in a shorter lifespan of components and compromised safety during storage of packaged products.
Surface rust and peeling coating are also common concerns. Tinplate, by design, has basic prevention from corrosion. However, during processing, any cutting or bouncing will compromise its protective coating. If components are also stored in damp and poorly ventilated systems, rust is likely to occur and can damage the appearance of the product and contaminate the contents of packages.
The misalignment and/or jamming of transmission components is typically due to metal dust accumulation, and/or lack of lubricants in operational use of the equipment.
To combat these common failures, we are recommending professional maintenance processes in conjunction with industrial practice.
First, optimize warehousing management: store in as dry, ventilated and constant-temperature environment as possible and sort products to minimize extrusion or impact with each other. Before assembly, conduct a rigorous visual inspection of the surface for physical damage or visual signs of coating damage to sort and discard any defective parts.
When the equipment is being operated, regularly calibrate (stamp, seam) stations to ensure tooling (dies) and component relationship matches as close as possible to prevent excessive wear. For sealing components, ensure material selection meets food grade and Corrosion Resistance factors based on packaging component contents, along with a regular timed replacement schedule. Also make sure transmission component parts are lubricated with special lubricant and have debris cleared on a regularly scheduled time frame to allow free transmission operation.
For components that experience surface rusting, investigate with professional rust removers and then protective coatings, but if corrosion has severely damaged a part, it needs to be removed from service immediately.
A normalized training procedure for staff operating the machinery is critical to prevent human related failures.
In practice, our company utilizes high precision stamping processes and custom tinplate raw materials, with strict quality control measures in place to deliver components that have excellent compression resistance, sealing performance, and corrosion resistance. Additionally, with the technical support team, our services include diagnostics of machinery failures and suggested routine maintenance methods at no fee for collaborative clients.
We will also continue to trial new production technologies or refine production processes in the tinplate can component materials industry, as we remain a provider of reliable supporting solutions and confidence for can-makers across the globe, sustaining growth and developments in the packaging materials industry.
