Calculate weight in kg.
D = diameter in mm
L = length in mm
G = specific gravity for grade (see above)
Weight in kg = 0.007854 x D2 x L x G
Calculate weight in pounds
D = diameter in inches
L = length in inches
Weight in pounds = 0.02837 x D2 x L x G
D = Outside diameter in mm
d = inside diameter in mm
Weight in kg = 0.007854 x (D2 – d2) x L x G
Weight in pounds = 0.02837 x (D2 – d2) x L x G
With over 80 years of experience in continually moving forward with the technology of materials development, Tufnol still finds thousands of new uses each year. Development is ongoing and our range of materials covers all grades and forms of laminated plastics, composites and resin bonded materials for engineering applications.
As an extremely cost effective method of producing plastics components in small to medium batch quantities, machining is suited to many engineering applications. It is also a practical method of producing complex components in resin bonded composites with high quality fibre reinforcements, which are not suited to moulding in sophisticated shapes.
Our technical capability combines high performance up-to-date CNC equipment with an unmatched depth of experience in machining laminated plastics and resin bonded materials and other engineering plastics.
We continually invest in the newest technologies, for example
Our Quality systems are an integral part of our culture. We hold registration to ISO 9001:2008 and our Quality Management System complies AS/EN 9100:2009. We are Signatory to SC 21, the British Aerospace industry programme promoting Supply Chain Excellence in the 21st century and hold many major company approvals.
