Unitized piston 720 'Hallite'

Unitized piston 720 'Hallite'

A completely self-contained assembly that integrates the piston, wear ring, and seal, solving the difficult issues of assembly!

The Hallite Unitized Piston 720 is a cost-effective alternative to traditional piston assemblies that install seals and wear rings separately. By molding the wear ring material to the outer diameter of the piston, a very tight fit between the piston and the cylinder bore is achieved. The steel piston body is machined to precise dimensions. 【Features】 ■ Maximum bearing width relative to piston width ■ Compatible with many cylinder bore finishes ■ Improved resistance to lateral loads ■ Reduced fluid contamination ■ Minimizes metal-to-metal contact, extending lifespan ■ Compact piston design allows for extended stroke and reduced cylinder length ■ Improved supply chain management through reduced warranty claims, enhanced manufacturing capability, and decreased inventory Hallite is a group company of Michelin. *For more details, please refer to the PDF document or feel free to contact us.

Reverse engineering of mechanical parts and resin products using "spScan".

Reverse engineering of mechanical parts and resin products using "spScan".

Reverse engineering mechanical components such as screws and gears!

Mechanical components require precise 3D modeling because the accuracy of their shape and surface treatment directly affects product performance. spScan easily reproduces solid shapes based on point cloud data from non-contact scanning. It allows for intuitive functions such as rotational copying of shapes while reflecting the fitting accuracy with polygons, making it easy to create reverse surfaces. Solid modeling that meets the desired accuracy is possible even with complex primitive surface configurations. Additionally, it features multiple reverse methods (patch surfaces, CAD surfaces, partial reverse) that can be selected according to the application and modification scope of the parts, significantly reducing the time and effort from design to evaluation and remanufacturing.

[Processing Example] Slipper Ring

[Processing Example] Slipper Ring

Processing sequence and tool usage ensure that the thickness of the seal area falls within the standard range while maintaining sharpness! Achieving the roughness of the seal area.

We would like to introduce a processing example of the "Slipper Ring" conducted by Iida Manufacturing. By using a processing sequence and cutting tools that ensure sharpness to keep the thickness of the seal section within the standard range, we achieved the required roughness of the seal section. This product allows for both sliding performance and sealing capability by pairing the sliding part's seal with an "O-ring." 【Processing Details】 - Used processing sequence and cutting tools to ensure the thickness of the seal section is within the standard range - Achieved the required roughness of the seal section *For more details, please refer to the PDF document or feel free to contact us.

Compression and restoration characteristics: Spring-loaded C-ring Heliflex series

Compression and restoration characteristics: Spring-loaded C-ring Heliflex series

Introducing the compression and recovery characteristics of the HELICOFLEX® series!

We would like to introduce the compression and recovery characteristics of our HELICOFLEX® series. The compression recovery of the HELICOFLEX series features a gently flattening compression curve. The recovery curve takes a different shape than the compression curve. This is the result of two permanent deformations (the elastic deformation of the spring and the plastic deformation of the outer casing). Each value is determined by the allowable leakage amount and the selection of materials. We have included a diagram with detailed information in the catalog, so please feel free to download and take a look. *For more details, please refer to the PDF materials or feel free to contact us.

C-shaped cross-section low tightening pressure metal seal C-ring 'C-FLEX TM'

C-shaped cross-section low tightening pressure metal seal C-ring 'C-FLEX TM'

We introduce C-rings with sections and thicknesses that take into account compressive loads.

The sealing concept of "C-FLEX TM" is the elastic deformation of a metal seal with a C-shaped cross-section. It is compensated by the internal pressure of the equipment to accommodate low design tightening pressure and uneven surfaces of the flange. It is utilized in a wide range of applications, including crude oil extraction, industrial turbines, valves, aerospace, automotive, and SOFC fuel cells (750°C for 40,000 hours). 【Features】 ■ Unique C-shaped cross-section structure ■ Cross-sectional diameter and thickness designed for low tightening pressure ■ Compatible with internal pressure, external pressure, and axial direction ■ Low design tightening pressure ■ Pressure range: from medium vacuum to 200 MPa (2000 bar) ■ Temperature range: -273 to 730°C (-46 to 1350°F) ■ The structure enhances sealing performance by providing auxiliary force from the operating pressure on the equipment side to the C-FLEX. *For more details, please refer to the PDF document or feel free to contact us.
