Product Details

Drawn Over Mandrel Tubes (DOM)Drawn Over Mandrel tubes according to tubing manufacturing standards like ASTM A513 type-5 & -6 or equivalent to meet customers requirements. Drawn over Mandrel (DOM) can be an ideal choice where a high degree of dimensional accuracy is required.

Applications:

Hydraulic cylinders 

Transmission shafts 

Steering Columns 

Suspension components 

Camshafts 

Axle Tubes 

Drive Shafts 

Jack Sleeves 

Bushings

Manufacturing procedure

DOM steel tubing is manufactured from electrical resistance welded hollows and cold drawn through a die and over a mandrel, improving surface finish, mechanical properties and dimensional accuracy of both outside and inside diameters. DOM is a high-quality, cost-effective choice for demanding applications and machined parts because of its special characteristics: Combined with reliable weld integrity, Maximum concentricity, and Minimal wall variation.

Advantages 

Improved Dimensional Accuracy 

Improved Physical Properties 

Improved Surface Finish 

Straightening, Complete Dimension, and Non-Destructive Inspection are Integral to the Process 

Lower Machine Costs 

Mass Savings in High Strength-to-Weight Ratio Applications
