I. Products That Typically Require a Soundproof Enclosure<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n\n
Product Type \/ Characteristic<\/span><\/th>\nReason for High Noise<\/span><\/th>\n<\/tr>\n<\/thead>\n
Hard, heavy metal parts<\/span><\/strong>\u00a0(e.g., steel screws, bolts, nuts, rivets, pins)<\/span><\/td>\nMetal\u2011to\u2011metal contact generates loud impact noise.<\/span><\/td>\n<\/tr>\n
Small, rigid parts<\/span><\/strong>\u00a0(e.g., bearings, small gears, machine components)<\/span><\/td>\nHigh\u2011frequency impacts produce sharp, irritating sounds.<\/span><\/td>\n<\/tr>\n
High\u2011speed feeding applications<\/span><\/strong>\u00a0(e.g., feeding at 300+ parts\/min)<\/span><\/td>\nFaster bowl operation increases both vibration noise and part\u2011to\u2011part collision noise.<\/span><\/td>\n<\/tr>\n
Large bowl with high amplitude<\/span><\/strong>\u00a0(e.g., feeding parts > 50 mm)<\/span><\/td>\nLarger bowls and higher vibration energy produce louder mechanical noise.<\/span><\/td>\n<\/tr>\n
Parts with sharp edges or rough surfaces<\/span><\/strong>\u00a0(e.g., stamped metal parts, formed components)<\/span><\/td>\nRough surfaces increase friction noise and part\u2011to\u2011part scraping.<\/span><\/td>\n<\/tr>\n
Parts that tumble or bounce<\/span><\/strong>\u00a0(e.g., disc\u2011shaped or irregular parts)<\/span><\/td>\nParts that roll or fall over during feeding create additional impact noise.<\/span><\/td>\n<\/tr>\n
Long or heavy parts<\/span><\/strong>\u00a0(e.g., long pins, thick washers)<\/span><\/td>\nHeavier parts create more kinetic energy and louder impact when they strike the track or each other.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n

II. When an Enclosure Is Almost Always Required<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n
Condition<\/span><\/th>\nWhy<\/span><\/th>\n<\/tr>\n<\/thead>\n
Operator station nearby<\/span><\/strong><\/td>\nExposure > 85 dBA for 8 hours is a health risk; enclosure protects workers.<\/span><\/td>\n<\/tr>\n
Open workshop with multiple machines<\/span><\/strong><\/td>\nFactory\u2011wide noise level must be controlled to avoid cumulative noise exposure.<\/span><\/td>\n<\/tr>\n
Medical \/ pharmaceutical \/ cleanroom environment<\/span><\/strong><\/td>\nNoise can be a disturbance and may affect operator concentration; enclosure also contains dust.<\/span><\/td>\n<\/tr>\n
Office or laboratory attached to the production area<\/span><\/strong><\/td>\nNoise must be kept below typical office noise limits (e.g., < 55\u201360 dBA).<\/span><\/td>\n<\/tr>\n
Local noise regulations require \u2264 75\u201380 dBA at operator position<\/span><\/strong><\/td>\nEnclosure is a simple and effective way to meet legal noise limits.<\/span><\/td>\n<\/tr>\n
Night\u2011shift operation<\/span><\/strong><\/td>\nNoise restrictions are often stricter at night.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n

III. When an Enclosure May NOT Be Needed<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n
Condition<\/span><\/th>\nWhy<\/span><\/th>\n<\/tr>\n<\/thead>\n
Plastic or soft rubber parts<\/span><\/strong><\/td>\nLower impact noise due to softer material.<\/span><\/td>\n<\/tr>\n
Very low speed<\/span><\/strong>\u00a0(< 30 parts\/min)<\/span><\/td>\nLow\u2011energy impact produces little noise.<\/span><\/td>\n<\/tr>\n
Remote installation<\/span><\/strong>\u00a0(bowl is far from operator, e.g., behind a wall or in a separate room)<\/span><\/td>\nOperator exposure is already low.<\/span><\/td>\n<\/tr>\n
Small, lightweight parts<\/span><\/strong>\u00a0(e.g., plastic clips, foam pieces)<\/span><\/td>\nMinimal collision noise.<\/span><\/td>\n<\/tr>\n
Short production runs<\/span><\/strong>\u00a0(e.g., 1\u20132 hours per day)<\/span><\/td>\nExposure time is short; risk is lower.<\/span><\/td>\n<\/tr>\n
Factory has no noise limit requirement<\/span><\/strong><\/td>\nIf no regulation exists, an enclosure is an optional extra.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n

IV. Typical Noise Levels by Part Type<\/span><\/h3>\n
\n\n\n\n\n\n\n\n\n\n\n
Part Type<\/span><\/th>\nTypical Noise Level (Without Enclosure)<\/span><\/th>\nEnclosure Recommended?<\/span><\/th>\n<\/tr>\n<\/thead>\n
Plastic caps<\/span><\/strong>\u00a0(soft)<\/span><\/td>\n70 \u2013 80 dBA<\/span><\/td>\nOptional (usually not needed)<\/span><\/td>\n<\/tr>\n
Aluminum screws \/ nuts<\/span><\/strong><\/td>\n75 \u2013 85 dBA<\/span><\/td>\nYes, if operator nearby<\/span><\/td>\n<\/tr>\n
Steel screws \/ rivets<\/span><\/strong><\/td>\n85 \u2013 95 dBA<\/span><\/td>\nStrongly recommended<\/span><\/td>\n<\/tr>\n
Steel bearings \/ heavy pins<\/span><\/strong><\/td>\n90 \u2013 100+ dBA<\/span><\/td>\nRequired for most factory conditions<\/span><\/td>\n<\/tr>\n
Glass \/ ceramic parts<\/span><\/strong><\/td>\n85 \u2013 95 dBA<\/span><\/td>\nRequired (also protects parts)<\/span><\/td>\n<\/tr>\n
Rubber O\u2011rings \/ seals<\/span><\/strong><\/td>\n65 \u2013 75 dBA<\/span><\/td>\nUsually not needed<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
