Features of our products:

Durable

Excellent tensile strength

Accurate level of tolerance

Good dimensional accuracy

Superb surface finishing

Easy to use and install

Possible defects:

There are no these problems for us.

Uniform wall thickness will ensure uniform cooling and reduce defects. 

A thick section, often referred to as a hot spot, causes uneven cooling and can result in shrinkage, porosity, or cracking.

Corners

Round corners to reduce stress concentrations and fracture

Inner radius should be at least the thickness of the walls

Machining allowance:
Add 0.0625 - 0.25 in. (0.16 - 0.64 mm) to part dimensions to allow for machining to obtain a smooth surface.
