Branson Worldwide – Best for Plastics - Branson Ultrasonics BV

Branson Worldwide – Best for PlasticsBRANSON offers awide range of successfulwelding techniques,based on the know-howgathered in over50 years on the globalmarket. Simultaneously,international presence isan important basis forour special consultingteams when analysingproblems in key industries.It goes withoutsaying that our customerscan depend on ourdiscretion in findingsolutions.Improved vibration head concept PPL+ (Power Package Linear Plus)The software of the digital frequency converter hasbeen further developed and eliminates a physical disadvantagethat occurs with three-phase coil technology,involving the coil forces partially counteractingeach other.Another advantage of this new drive is the increasedrange of upper tool weights that can be used. Theweight can vary ± 30% from the nominal value without affecting the drive power.Optimized amplitude regulators additionally allowcontrolled remping and release times. Both have apositive effect on the mechanical and visual seamproperties.Plastic manifolds: Two-shell technology establishedGlass fiber reinforced polyamide (PA-GF) is a high qualitymaterial specially designed for plastic manifolds. It meetsthe mechanical and thermal requirements such as highbursting pressure and high thermal load at moderate materialcosts. But the positive characteristics are overshadowedby enhanced welding machine requirements. With thesupport of the powerful M-series, the two-shell technologysuccessfully penetrated the automotive market and is nowalso used for 8-cylinder engines.Beside air-intake manifolds there are many other independentapplications under the hood and in the vehicle interior:air filter housings, brake fluid tanks, airbag covers,instrument panels.CAD drawing of vibration head concept PPL+Samples of vibration welded plastic manifolds made of PA-GFPC control with process data managementAlmost every vibration welding machine is equippedwith our innovative PC control “VC 100“ as a standard.It applies a powerful industrial computer andcontrols the complete welding process. While themachine and tooling functions are initiated and surveyedby an integrated Soft-PLC, the system is operatedthrough a multilingual, graphical user interfaceon a touch screen – completed by a context-orientedmenu structure and extensive help modules.The “VC 100“ enables varying operation modes andparameters as well as an easy to-use, free programmingof the weld cycle and additional functions.This includes control over an optional IR preheatingunit (medium wave foil emitter, adapted to the weldcontour), for creating clean, particle-reduced weldseams.With the database, you can save and export anynumber of setting combinations and reload them, depending,for example, on the tool coding. Thanks to the serial recording of all importantprocess parameters, this PC controller provides efficient management of weld data with numerousvisualisation features, analysis tools as well as import/export routines. The TeleService function additionally enablesremote diagnosis, online support and online training. This ensures machine availability and targeted optimisation of theproduct quality.High fusion performanceThe M-series with improved drive system leads to remarkableadvantages with the nominal frequency range of240Hz. Concerning the plastification it was possible toachieve a power increase of up to 100%. We guarantee thatthe high welding performances indicated for PP in thetable will be achieved. For other materials, the user mayequally assume over-average values. The exact values willalso be covered by our guarantee, after tests in our applicationlaboratory. Due to the larger work area, the peak-to-peak amplitude range of 0,9 to 1,8 mm can now also beused for applications with substantially larger joint surfacesor for materials that are difficult to weld, independent ofthe frequency.Finally, the high performance drive system allows smallermachine frames and therefore a more compact system.These advantages result in a smaller expenditure on capitalassets for the system and consequently lower unit costsduring manufacturing.Vibrationwelding systemmodel M-624 HiModel M-112 H M-202 H** M-402 Hi** M-502 Hi** M-512 Hi** M-522 Hi M-622 Hi M-624 Hi M-822 Hi M-824 Hi M-836 HiVibration frequency [Hz]240 (nominal)Vibration amplitude [mm]0.9-1.8 (peak-to-peak)Weld plane [cm 2 ]* 15 75 150 150 200 250 250 500 250 500 750Max. clamp force [kN] 2.5 4.5 15 18 18 18 25 25 25 25 30Direction indicator light:The interesting microscopephotograph shows a typicaljoint segment of agood weld of ABS and PMMAachieved by means ofvibration welding.Dimensions of lift table (WxD) [mm] 100 x 100 500 x 525 800 x 400 1020 x 540 1020 x 540 1020 x 540 1330 x 540 1330 x 540 1500 x 600 1500 x 600 1500 x 600Weight of upper tooling [kg] 1.5-2.5 5.0-7.5 15-25 15-25 25-35 25-50 35-65 35-65 35-65 35-65 50-100Control PLC PLC PLC/VC 100 PLC/VC 100 PLC/VC 100 PLC/VC 100 PLC/VC 100 PLC/VC 100 PLC/VC 100 PLC/VC 100 PLC/VC 100* dependent on the material and geometry of the application ** not with PPL technology
