Plastic design guide rules include considerations for material selection, part geometry, and manufacturing processes.

• Choose the appropriate plastic material based on properties such as strength, stiffness, and temperature resistance.

• Design parts with uniform wall thickness to avoid warping and sink marks.

• Avoid sharp corners and edges to prevent stress concentration and cracking.

• Consider draft angles for easy part eject...read more

Injection molding is a manufacturing process used to produce parts by injecting molten material into a mold.

• The process involves melting plastic pellets and injecting them into a mold cavity

• The mold is then cooled and the part is ejected

• Injection molding is used to produce a wide range of products, from small parts to large automotive components

• It is a highly efficient process that can produce parts with high precision
