Draft
Amount of taper for molded or cast parts perpendicular to the parting line. An angle is incorporated into a wall of a mold so that the opening of the cavity is wider than its base. Draft angles allow for easier ejection of the part from the mold.- Smooth Texture: 1° draft preferred minimum
- Light Texture: 3° draft preferred minimum
- Heavy Texture: 5° draft or more preferred minimum
Surface Finish
Dents or markings distort the plane of a surface, causing light to reflect in a way that our eyes instantly identify as an inconsistency. Added texture aids in concealing blemishes and creates a friction factor on the surface of finished parts providing anti-slip qualities.- Non-Cosmetic
- Rough
- Smooth
- High Polish
Tolerances
Allowable variation for any given size in order to achieve proper function when considering the design intent. As with all molded products, part material’s shrink value should be considered when building your pattern and mold.- ±.005”
