Construction and agricultural machinery operate under continuous dynamic load and harsh outdoor conditions. Hydraulic cylinders, steering systems, and lifting mechanisms must function reliably despite vibration, contamination, and wide temperature variation.
Sealing systems in these applications must balance wear resistance, dimensional stability, and contamination exclusion to maintain equipment uptime and reduce maintenance frequency.
Sealing components in construction and agricultural systems are exposed to combined mechanical stress and environmental contamination. Typical challenges include:
These conditions require careful material selection, optimized seal geometry, and controlled manufacturing processes.
Pulim approaches mobile equipment sealing through structured evaluation of load conditions, motion type, contamination exposure, and installation geometry. Wear-resistant polyurethane systems are commonly selected for dynamic applications, while PTFE-based materials may be applied where friction reduction is required.
Seal profiles are optimized to balance sealing force with contamination exclusion. Dual-process manufacturing (injection molding and CNC machining) supports both standardized cylinder designs and non-standard dimensions.
Engineering validation is completed prior to production to ensure stability under load-intensive operation.
Pulim supplies sealing products commonly used in construction and agricultural equipment, including:
Material options include PU systems, PTFE and filled PTFE grades, and performance elastomers depending on application requirements.
Pulim applies material validation and dimensional inspection processes aligned with heavy-duty hydraulic applications. Testing may include abrasion resistance evaluation, compression set analysis, and mechanical property verification.
Manufacturing is conducted under established quality management systems to support batch consistency and repeatable production performance.
Mobile machinery projects often require a combination of high-volume OEM supply and customized replacement components. Pulim supports these requirements through injection molding for consistent production and CNC machining for non-standard or large-diameter seals.
Digital production systems assist in maintaining repeatability and process control across long-term supply projects.
