Draft
Draft is the 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: 0° draft acceptable in some cases
- Smooth Texture: 1° draft preferred minimum
- Light Texture: 2° draft preferred minimum
- Heavy Texture: 3° draft preferred minimum
Wall Thickness and Radius
- Minimum .0625”
- Maximum .500”
- Preferred minimum corner radius .250”
Surface Finish
With an open mold process, the tool side can capture a smooth, polished surface finish with the non-tool side having a rough or unfinished surface. Non-tool side can be gel coated splattered or painted.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.- Tool side ±.010”
- Non-tool side ±.060”
Customer Testimonial
“Skyline Attractions is a true believer in get it done right the first time. Ralph Albert’s new fiberglass shop lives up to that same motto and was instrumental in helping Skyline Attractions get two new products to the IAAPA tradeshow in record time. The quality and turnaround time on 2 large prototype parts was well and beyond our expectation.” – Chris Gray, Skyline Attractions Owner
