Question

Injection molding can be used for parts of thickness up to __________

(a) 4 mm

(b) 6 mm

(c) 8 mm

(d) 12 mm

This question was posed to me in homework.

This interesting question is from Ceramic Formation & Clay Ceramics topic in chapter Composite & Ceramic Materials of Engineering Material & Metallurgy

Answer 1

Right option is (b) 6 mm

Explanation: Injection molding forms thin, long, and twisted shapes with good reproducibility. They cannot, however, be used for parts whose thickness is more than 6 mm. Another major disadvantage of injection molding is that the cost of molds is generally high.
