Applications of Frame-Type Hydraulic Presses in the Electronics and Electrical Industry

In the electronics and electrical sector, frame-type hydraulic presses primarily handle three core tasks: precision press-fitting, the molding of insulating components, and the forming of conductive copper materials. The resistance to off-center loads—afforded by their highly rigid frames—is crucial for ensuring assembly precision for electronic components and consistent quality for electrical insulation parts. The following information is provided by Jianlong Hydraulic Technology; please feel free to contact us with inquiries.

1. Key Applications

1.1 Precision Press-Fitting of Electronic Components

Applications requiring high-precision press-fitting—such as electronic connectors, electrical parts, and motor stators/rotors—rely on the precise pressure control and stable guidance systems of frame-type hydraulic presses. The equipment ensures components remain undamaged during the process, maintaining pressure errors within ±0.5% and positioning accuracy within ±0.01mm. Typical applications include the press-fitting of circuit boards and electronic modules, as well as the leveling of silicon steel sheets.

1.2 Molding of Electrical Insulation Components

Insulation components for equipment such as high-voltage switchgear, instrument transformers, charging piles, and energy storage cabinets are often manufactured via hot-press molding using composite materials like SMC, BMC, and epoxy fiberglass. Thanks to their resistance to off-center loads, frame-type hydraulic presses avoid issues common to traditional four-column presses—such as slide misalignment and uneven force distribution—when forming irregularly shaped insulation parts, thereby reducing the scrap rate from 12%–18% to under 2%.

• 800-Ton Class: Suitable for the mass production of small-to-medium instrument transformer housings, insulation blocks, and similar parts.

• 1000-Ton Class: Features a dual-cylinder synchronous structure; used for large, ultra-high-voltage insulation cylinders and thick-walled insulation components to ensure high density and prevent delamination.

1.3 Precision Forming of Conductive Copper Materials

The bending, straightening, and press-forming of conductive components—such as copper bars, terminals, and busbars—require equipment capable of delivering stable pressure and precise stroke control. Frame-type hydraulic presses designed for precision copper forming (e.g., 630-ton or 800-ton models) ensure dimensional accuracy and operational stability for conductive components.

2. Selection Guide

2.1 100-ton class (e.g., YW34-100T): Suitable for pressing magnetic powder components and small electronic parts in electronics manufacturing facilities; achieves a pass rate of over 98%.

2.2 315-ton/400-ton class: Used for punching and forming cabinet side panels and instrument housings, balancing efficiency with flexibility.

2.3 800-ton/1000-ton class: Specialized for the hot-press molding of electrical insulation components; a mainstay for mass production in the power accessory and new energy storage sectors.
