SKU 001-0020MFR# 2005
Diameter
4.0 mm
Wire Wax is a sprue wax supplied as a wire for creating casting patterns. It is used to form sprues and runners in the investment process, facilitating the flow of molten metal into the mold cavity.
This sprue wax is provided in a 250 g roll with a 2 mm diameter, distinguished by its green color. Its formulation incorporates a special micro-molecular wax, resulting in a harder and more economical wax wire suitable for precise sprue formation in dental casting procedures.

About sprue wire wax
Sprue wire wax is wax in wire, rod and stick form, sold by diameter, that is attached to the wax pattern to form the sprue.
A sprue is the channel through which metal is poured or cast into a mold. A sprue former is the wax, plastic or metal pattern that forms that channel. Sprue design controls the velocity and the supply of metal to the mold.
How sprue wire wax and pattern wire wax differ
- Sprue Wire Wax — Wax wire that forms the channel for the molten metal.
- Pattern Wire Wax — Ready-made wax shapes that are placed on the cast in place of free-hand waxing.
What to look at when choosing sprue wax
Shape: a study of cobalt-chromium partial denture frameworks compared ribbon, square, round and round-with-reservoir sprues. Round sprues with a reservoir gave the most satisfactory fit with the fewest internal and external defects.
Diameter and hardness: the wire on this shelf is listed by diameter in millimetres, and some of it by hardness.
Distortion: a wax pattern can hold internal strains from the way it was worked, and it distorts when the strain relaxes. Time and temperature both make it worse, which is why patterns are generally invested immediately after they leave the die or cast.
