A
hydrofoil is a lifting surface, or foil, that operates in water. It can be applied on the kireboard, surfboard and SUP.
They are
similar in appearance and purpose to aerofoils used by aeroplanes. This surf
hybrid (aluminium-carbon) foil is made to lift off as early as possible on a
wave, an outside reef or soft wave. Its maneuverability and controlled
accelerations provide good steering to remain in the right section of the wave
when surfing.

Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, which is a foreign trade oriented economic developed city, adjacent to international port city Shanghai. Established in 2009, we're a manufacturing company specialized in the production of piston rods and linear shafts.
     Quality  is  Life  of  Enterprise. Your  Satisfaction  is  Our  Goal.      Â
Â
Main Products:
We offer the manufacturers of hydraulic and pneumatic cylinders a wide assortment of high quality tube and piston products.
Hard Chrome Plated Rod, Hydraulic Piston Rod, Cylinder Piston Rod, Chromium Rods, Hard Chrome Shaft, Induction Rod, Induction Shaft, etc.
Material: JIS S45C, SAE1045, DIN CK45
The hard chromium piston rods produced by our company come with more than JIS S45C material, where the rods first undergo precision milling and processing, and are then put through gard surface chromium treatment, allowing a surface precision level of f7, and a surface hardness reaching HV800 minimum and up, which not only help to improve wear resistance but also help to extend the life cycle of the rods, thus helping the customer save cost.
The corrosion resistances is tested in our own internal salt spray laboratory, and The rods surface heat treatment and hardness reaching HRC55°±2°, and at a hardened depth of between 0.5mm - 3mm, before the rods are put through precision milling and hard chromium treatment for a membrane thickness measuring 20 micron ± 10% to drastically improve the rod's wear resistance, and help to extend the life cycle of the rods.
The furnished products are ideal for a host of heavy machinery, construction equipment, and as position mount for a variety of heavy equipment.
Suzhou Weipeng products such as chromed steel bars and tubes are used in the fabrication of hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, product handling equipment, garbage collection, heavy equipment, and many other applications.
