The features of Halder's original new products have unique characteristics that are demonstrated in products and tools. Catalog and new product samples are available.
In 2017, Halder added modular fixture systems, multi-clamp systems, and versatile clamp systems to its traditional fixtures, clamps, and operating components, resulting in an even more comprehensive product lineup. A new type of spring plunger with a freely rotating tip has been added to the rich lineup, significantly reducing the burden on sliding parts. Additionally, the new oscillating pad features a mechanism that keeps the pad section in a horizontal position at all times, making it easier to use and ensuring a more secure hold on the workpiece. The modular fixture system allows for the combination of various elements like Lego blocks, enabling the holding and clamping of complex workpieces. By implementing this system, there is no longer a need to prepare dedicated fixtures each time. We have also increased the variety of new products and sizes. If you would like a catalog, please request it through the contact information below. For those interested in product descriptions, we have prepared a sample box focused on new products.
New product "Ball Rotating Spring Plunger" We will send samples and catalogs for free to those who wish.
The new product "Ball Rotating Spring Plunger" features a resin component between the ball and the spring, allowing the ball to rotate smoothly. Compared to conventional types where the ball and spring are in direct contact, this design minimizes wear and resistance with the counterpart components by allowing the ball to rotate freely. Additionally, since the ball is supported by resin, it is also suitable for situations where electrical insulation is required.
Spring (ball) plunger of self-retaining type that can be used for plastic molded products with large hole diameter tolerances.
The tolerance for the hole diameter for installing this product is allowed up to 0.2 mm. Adhesive is not required for installation, making assembly work easier. It is ideal for click mechanisms and simple fixing of plastic molded parts.

High-frequency use but long lifespan!
The spring plunger is an accessory for vacuum pads used for height adjustment during suction and to mitigate impacts. The FSTE-HD series spring plunger has the same basic design as the general-purpose FSTE series, but it uses stainless steel for the main rod, enhancing durability. It is suitable for applications with higher usage frequency. The stroke is available in five sizes ranging from 15mm to 90mm. (Note: Not all strokes can be utilized to prevent load and damage due to contact between springs.) A type with a rotation prevention feature suitable for use with oval pads is also available (FSTE-HD-VG). For more details, please contact us or refer to the catalog.
Internal spring type with no exposed springs!
The spring plunger is an accessory for vacuum pads used for height adjustment during suction and to mitigate impacts. The FSTI series spring plunger is a type that houses the spring inside. Since the spring is not exposed, it can be protected from dirt and other contaminants, ensuring a long lifespan. In the unlikely event that the spring is damaged, it prevents falling or contamination of the workpiece. Additionally, it has a structure that prevents the springs from hitting each other during compression, allowing for the full stroke to be utilized. The strokes are available in three sizes: 10mm, 25mm, and 50mm. There is also a type with an anti-rotation feature suitable for use with oval pads (FSTI-VG). For more details, please contact us or refer to the catalog.
Processes that require positioning accuracy and are suitable for stable transport of heavy workpieces!
The spring plunger is an accessory for vacuum pads used for height adjustment during suction and to mitigate impacts. The spring plunger FST-LOCK-HD can fix the stroke at any position, preventing deflection due to the weight of the workpiece when lifted, as well as misalignment and changes in the posture of the workpiece. It flexibly accommodates workpieces of different shapes and is suitable for transporting a variety of items with the same hand. For more details, please contact us or refer to the catalog.
