Packaging Machinery

• Affix CE mark and EU official-language safety warnings per Machinery Directive 2006/42/EC and EN ISO 13849-1. • Place ISO 7010 graphical symbols at

• Verify that opening guard door immediately cuts servo power; check relay contacts with multimeter; • Confirm interlock circuit meets CE EN ISO 13849

• Prevent pinch: fixed guards on shafts, gears, chains; openings ≤6 mm. • Prevent burns: heat-seal bars need thermal guards; isolate surfaces >60°C

• Install at least one e-stop on the main HMI panel and one at infeed/outfeed, reachable from any operator position. • Use red mushroom-head actuators

• Must stop: opening the safety door trips the interlock and cuts power, per GB/T 15706 and CE Machinery Directive. • Monitor door switches via safety

• Food-contact surfaces require FDA 21 CFR 177 or EU 10/2011 compliance statements plus migration test reports. • Stainless steel parts need EN 10204

• The contact-parts list verifies FDA/EU 1935/2004 compliance; non-contact parts need no food-grade certificate. • List each item's material grade

• Product-contact hopper, auger filler and former must be 316L stainless steel or PTFE-coated; carbon steel is prohibited. • Heat-seal jaws and sealin

• Yes, salt (chloride) corrodes stainless and carbon steel, shortening packaging machine life. • Salt-contact parts should be 316L stainless steel, no

• Test product pH and chloride level; use 316L or PTFE if pH<4 or Cl⁻>50ppm. • Ban carbon steel and aluminum on contact parts; use FKM or PTFE-e

• Quick disassembly and cleaning shorten changeover and cleaning downtime, directly improving OEE. • Food and pharma packaging must prevent cross-cont

• Set frequency by residue risk of product-contact parts: powders/sauces per shift, dry granules weekly. • Base it on fouling rate of heat-seal jaws,

• Use IP65 or higher enclosure with positive-pressure purge on the electrical cabinet to prevent dust ingress and shorts. • Seal bearings and guides o

• Dead zones trap product residue, breeding bacteria and failing FDA/CE hygiene certification. • Residual material absorbs moisture and cakes, cloggin

• Stainless frames (304/316L) resist washdown and food acid/alkali, meeting FDA/CE hygiene design. • Carbon steel rusts and flakes, contaminating food

• Fit a power-loss memory safety relay that drops servo enable and requires manual reset. • Add PLC power-up self-check: allow start only when heat-se

• If operators are multilingual, the HMI must offer EN/CN/local language switching to cut misoperation. • Confirm at purchase whether PLC/HMI language

• Positioning accuracy within ±0.1mm, repeatability ±0.05mm, governs film cut registration. • Rated/peak torque must cover film-tension peaks; keep ≥1

• Verify cabinet voltage/frequency (e.g. 380V/50Hz or 480V/60Hz) to match local grid and protect PLC/HMI. • Check breakers, contactors and servo drive

• Control logic governs cycle time, film tension and heat-seal consistency, affecting yield more than brand. • Brand affects spare parts, programming
