Product Description

Product Description

V/Y special-shaped riser is made of high-quality heat-insulating refractory aggregate  and appropriate amount of exothermic compound, which can meet the feeding needs of most disc type castings (eg: high-speed rail brake pads).

 

Flexible appearance and dimensions

FB square blind riser sleeves and FR square open riser sleeves are available; VB oval blind riser sleeves and VR oval open riser sleeves are available;

YB waist round blind riser sleeves and YR waist round open riser sleeves are available;

 

Quick custom delivery available

Thanks to the negative pressure suction filtration process used in the manufacturing process, the appearance dimensions can be changed at any time according to

customers' requirements and put into mass production quickly. The cycle from

sample preparation and mold opening to mass production can be shortened to less than 48 hours to quickly respond to the sample delivery needs.
