Wax Cotton Cord

Listing ID #3585322

It has easy bending and non-deforming properties. A Cotton thread inside the rope is given to maintain continuity.Cores embedded with wax rope, after baking or curing, the wax rope melts leaving behind a clean passage, for gases evolved to escape, which are generated during metal pouring.Twist two ropes length-wise, while making the cores, place them in the area to be vented, extend it to the cores print. Care should be taken to extend all wax ropes to the core print. To get best result, make circular mark in core print area of the core that all wax terminated at that point, corresponding similar mark should be made on the pattern so that pepper holes are made in mould to allow wax to melt out during oven drying. Ropes can be joined easily by pressing and twisting.
