In injection molding, calculating the OEE (Overall Equipment Effectiveness) is crucial to optimizing the operational efficiency and productivity of production lines. OEE measures not only machine availability, but also the performance and quality of the products manufactured. However, many factories struggle to calculate and interpret this data correctly. This is a recurring problem in industry, and can lead to additional costs and a lack of competitiveness, making it essential to integrate a rigorous approach to TRS monitoring.

The difficulties encountered in calculating OEE for injection molding often lie in a misunderstanding of the three key components of OEE: availability, performance and quality. Sometimes, data collection systems are not sufficiently integrated, leading to misinterpretation and unresolved downtime.Understanding TRS / OEE is essential for any team seeking to improve these indicators.

To solve these problems, companies can turn to advanced digitalization solutions like those offered by TeepTrak. The implementation of IoT sensors and real-time analysis software enables greater visibility and rapid identification of sources of efficiency loss. By combining these tools with continuous improvement strategies such as Lean Manufacturing and Total Productive Maintenance, plants can increase their OEE by minimizing unplanned downtime and optimizing every aspect of the production process.

Consider the example of a company specializing in plastic injection molding, which implemented the TeepTrak solution to digitize its performance monitoring processes. Prior to integration, the company was losing an average of 10 hours of production per month due to unplanned stoppages. Thanks to TeepTrak’s real-time analysis, it was able to reduce these stoppages by 50% by identifying bottlenecks and readjusting maintenance schedules. This rapid return on investment not only increased their OEE to 85%, but also improved the quality of finished products.

It is imperative for industrial decision-makers to structure a TRS/OEE project to guarantee a real competitive advantage. Adopting a solution like TeepTrak’s not only improves performance indicators, but also provides a clear view of processes. By starting with an accurate OEE assessment, managers can prioritize necessary improvements, reduce costs and maximize profitability. The potential of such an approach is immense: it identifies strategic priorities, frees up resources and boosts overall plant performance.

FAQ

Question 1: How does TRS affect the performance of my injection molding line?

A low OEE indicates inefficiencies in availability, performance or quality, leading to productivity losses and increased costs. Improving OEE helps optimize every aspect of production, reducing downtime and maximizing output quality.

Question 2: Where do I start to improve OEE in my plant?

Start by assessing the three components of OEE: availability, performance and quality. Identify the main sources of losses, then implement solutions like TeepTrak’s tools for real-time monitoring and continuous improvement.
