Some draft angle is better than none and more draft is desirable if the design permits. Where minimum draft is desired, good polishing is recommended and feature depth should not exceed .5in. Wall Thickness. The number one rule for designing plastic parts is uniform wall thickness. Uniform walls aid in material flow in the.
Plastics are used in a variety of diverse and demanding applications; There are design elements that are common to most plastic parts. Wall thickness; Ribs; Bosses; Gussets; Draft. General Design Guidelines. Keep walls as thin as possible. Thick enough to meet strength requirements; If too thick part will warp or crack
Coupling relays. ? For galvanic isolation and conversion of analog signals. Interface converter. ? Switching large power ratings with low space requirements Design. 3SU1 gives a new face! Basic Design. Plastic. Metal shiny. Flat. Metal matt. Key. Factor. • Combination of Design and functionality! • Self-explained assembly.
Requirements. The most important first step in designing a plastic part is to define properly and completely the environ- ment in which the part will operate. . a number of parts for preliminary testing at low cost. However, this method may be of limited value since the tool was designed for die cast metal, not for plastics.
Once a component is designed, a mold is made and preci- sion machined to form the features of the The injection molding process uses a granular plastic that is gravity fed from a hopper. A screw-type plunger forces the Examples might include ribs, bosses, or any other projection of the nominal wall. Since thicker walls
