Designing for Thixomolding
Thixoforming can help you design your parts from start to finish.
- Think Plastics when designing for Thixomolding!
- Runner designs are similar to plastics.
- Uniform wall thickness is best.
- Thick to thin flow when walls are not uniform thickness.
- More draft is better but zero draft is possible in some cases.
- Utilize coring, ribbing and bosses to reduce weight and minimize sinks.
- Slides, cams and lifters possible for complexity.
- Assembly with fasteners, adhesives and possible snap fit.
- Gates are much larger than in plastics.
- Larger venting and use of overflows in some cases.
- Minimum Part Size Wt ≈ 1.5 grams.
- Minimum Wall Thickness t ≈ 0.5 mm = 0.020”.
- Flow Distances (from Gate) as Far as 150×t.
- Maximum Wall Thickness: t ≈ 10.16 mm = 0.40” with less than 2.5 % porosity.
- Thicker walls are possible.
