Edge trimming hydraulic presses are specialized finishing equipment used for precision shearing and cleaning of flash, burrs, and gates on metal parts (especially those formed by casting or forging). Their application scope can be understood from three dimensions: applicable processes, applicable industries, and applicable parts. Below is a sharing from Jianlong Hydraulic Technology for your reference!

1. Classification by Applicable Processes
Edge trimming hydraulic presses are mainly used for the following two main forming processes in post-processing finishing:
1.1 Edge trimming after forging: This is the most classic application. It is used to cleanly shear and separate the flash generated during the forging process from the main body of the forging.
1.2 Edge trimming after die casting: Used to remove flash from the gating system (gate, overflow groove) and parting surface generated during the die casting process.
2. Classification by Applicable Industries and Typical Parts
The table below clearly illustrates its wide range of cross-industry applications:
Applicable industries | Examples of typical parts | Core functions and requirements |
Automotive Manufacturing | Engine connecting rods, crankshafts, gearbox gears, synchronizer rings, wheel hubs, brake discs | Efficient and high-precision removal of burrs to ensure dynamic balance and assembly accuracy is a critical link in the production of safety components. |
Aerospace | Titanium alloy and high-temperature alloy forgings such as turbine disks, blades, and landing gear structural components | Handling high-value, high-strength materials requires equipment with extremely high rigidity and precision to avoid damaging parts. |
Construction Machinery | Hydraulic valve blocks, gear rings, large shaft forgings | "For parts with large dimensions and thick flash, the equipment requires a large tonnage, a wide worktable, and high stability." |
Hardware Tools | Wrenches, pliers, hammers, and tool blanks | "For cleaning parts with complex contours, improving product appearance and safety, suitable for mass production." |
Consumer Goods | "Stainless steel cookware with laminated bottoms, high-end faucet blanks, die-cast appliance housings" | "Achieve clean cutting, avoiding subsequent grinding, directly obtaining a substrate suitable for polishing and electroplating." |
3. Important Technical Notes
3.1 Mold Dependence: Trimming hydraulic presses must be used with dedicated trimming dies. The design and manufacturing quality of the die directly affects the trimming effect and lifespan.
3.2 Precision Development: Modern servo CNC trimming hydraulic presses can achieve higher position and pressure control precision, suitable for precision parts and integration into automated production lines.
3.3 Automation Trend: In industries such as automotive and bearings, trimming hydraulic presses are often used as the core of automated finishing units, integrated with robots and conveyors to achieve fully automated production.

In short, if your parts originate from forging or die-casting processes and require efficient, batch removal of flash or gates, a trimming hydraulic press is usually the most professional and effective choice.
