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.

Metal Ring Manufacturing Technology "Bender Method"

Metal Ring Manufacturing Technology "Bender Method"

High quality, high yield, and low cost are its features!

The "Bender Method" is a manufacturing process for metal rings that utilizes cold bending and welding techniques. After cold rolling round steel into long steel materials, it is bent to a specified diameter, then spirally bent and stacked, cut into individual pieces, and welded to form a true circular ring. The yield of raw materials is 95%, resulting in minimal material loss. In the process of forming true circular rings through cold rolling → bending → cutting → welding → heat treatment → straightening, the Bender Method finishes metal rings with a roundness of within 0.5mm. *For more details, please feel free to contact us.

Powder metallurgy products

Powder metallurgy products

We manufacture and sell a wide variety of products using the powder metallurgy method (sintering process).

Our company handles powder metallurgy products, which are created by placing "metal powder" into a "mold," compressing it with a "press machine," and then sintering the formed material in a "sintering furnace" at high temperatures to produce products (components). By controlling the mixing of metal powders, we can create products (components) with the necessary characteristics. Additionally, further post-processing can impart even more characteristics, which vary depending on the products (components) used. 【Product Lineup】 ■ Shock absorber components ■ Compressor components ■ Hydraulic pump components ■ Oil-impregnated bearing components ■ Others *For more details, please download the PDF or contact us.
