1. Introduction
Marine rubber fender is an elastic buffer device, which is widely used in the side of vessel or wharf. Its function is to protect the boats from being damaged by slowing down the impact force between vessel and wharf or vessel and vessel in process of ships dock.
2.Classification

Front Frame &Â UHMW-PE Pads
Front panels are complex steel fabrications designed for working with cell fender, cone fender, element rubber fenders and other types. It is necessary part of fender system as they can distribute the reaction force form the rubber fender into the hull of vessels.
UHMW-PE pads, generally fixed to front panels, can provide the best combination of price and durability to the whole fender system. The pads are characterized by higher abrasion resistance and low-friction surface, excellent durability and high toughness. It efficiently protects the painting of vessels from damages caused by friction.
Steel chains
Steel chains are used to fasten cylindrical fenders, pneumatic fenders and other types of fenders for providing excellent control of fenders such as the deflection and shear strength during impact. Normally, there are two main types of steel chain systems are commonly used for fender installation as shown in the picture.
Anchor Bolts and Nuts
anchor bolts and nuts in accordance with rubber fenders you bought can also be supplied. They are necessaries for installation of cell rubber fender, DÂ fenders, cell fenders, element rubber fender and various types of fenders.

Needle roller punching machine series
The punching machine is a kind of mechanical equipment that is driven by the power mechanism after the raw material is installed, and the punching die acts on the material to complete the punching. The punching machine can perform operations such as sheet processing, stamping, molding, embossing, etc. that force metal into the mold.
The series of desiccant deoxidizer film perforating needle rollers developed by our company adopts imported alloy steel wire needles with high strength and good abrasion resistance, and advanced perforation technology. The processing accuracy reaches the same level in the world. The air permeability detection is uniform and stable.
This series of needle rollers are widely used for perforating various kinds of desiccant deoxidizer films for food, various kinds of micro-perforated or air-impermeable plastic packaging films, and medicinal packaging films. There are cold perforated needle rollers for direct perforation and heated perforated needle rollers.
Our company specializes in the supply of desiccant perforated needle rollers, deoxidizer film perforated needle rollers, wholesale of film perforated needle rollers, product quality and processing technology reliability, and stability are at the domestic advanced level, and can be produced according to customer requirements. Special specifications of needle roller, needle ring products. Welcome customers to consult.
