Ceramic Riser Tubes

Introduction

Ceramic riser tubes are a key component for the manufacture of aluminum alloy products (especially for automotive parts) on low pressure casting machines. During casting production, the ceramic riser tube is directly in contact with the aluminum molten alloy so the quality and performance of the ceramic riser tube for the low pressure casting are quite demanding. The ceramic riser tubes produced by Tech Ceramic have not only good thermal shock resistance, high temperature creep resistance, acid and alkali resistance, oxidation resistance, resistance to molten metal corrosion such as aluminum, lead, tin, zinc, etc., but also has excellent thermal shock resistance, can meet the requirements of the low pressure foundry industry.

Aluminum Titanate Riser Tubes

Aluminum titanate riser tubes can not be wetted by aluminum alloy liquid and are featured with excellent resistance to thermal shock, low thermal conductivity which saves energy and their outstanding chemical and abrasive resistance ensure high purity of molten alloy.

Silicon Nitride Riser Tubes

Silicon Nitride has been known for its low wettability and superior corrosion resistance of non ferrous metal melts. Silicon Nitride Low Pressure Riser Tubes offer long service lifetimes, due to good thermal shock resistance and good corrosion resistance.
