Trimming Press

Hydraulic trimming press is an industrial machine utilized for cutting, trimming, and stamping processes. It employs hydraulic power and a compact 4-post structure, primarily used for die cutting or removing burrs from die castings. The entire body is made of high-quality low carbon steel, with the four columns coated in hard chrome alloy. The inclusion of internationally top-tier components and exceptional craftsmanship guarantees the machine’s lifespan of several decades, allowing it to operate continuously and stably under high-temperature and high-load conditions. All pipes, flanges, and joints are designed to prevent vibrations and leaks. The hydraulic system is mounted on top to save floor space. Both the upper slide and the worktable are equipped with T-slots for mold installation, and optional hydraulic center ejection is available. The trimming press achieves a positioning accuracy can reach 0.01mm, combined with a high-frequency hydraulic response system, ensuring high-speed and precise workpiece processing.

The Lexson series of Trimming Presses, renowned for their simplicity, precision, efficiency, and exceptionally extended operational lifespans, have been exported to over 40 countries. They find extensive application in the trimming of various materials, including metal die-castings, rubber, automotive components, aerospace industry, and more.

Trimming Press Structure

Our hydraulic trimming press has a modern appearance and compact four-column design for convenient loading and unloading of dies or tools. The frame is made through integral welding process, with a small footprint. The machine body undergoes heat treatment, sandblasting, and shot blasting processes. The spacious worktable and long stroke are suitable for accommodating large workpieces. Dual hydraulic main columns ensure even pressure distribution, guaranteeing smoother cutting edges. Depending on requirements, 2-4-sided metal safety guards can be configured, with optional pneumatic safety guards.

The bed of Lexson’s trimming press series undergoes finite element analysis to ensure minimal deformation under hydraulic pressure. It exhibits surface fatigue resistance, resistance to alternating loads, and wear resistance, making it suitable for continuous operation under high-temperature conditions.
