best dk400h hot plate plastic welding machine near me

HOT-PLATE PLASTIC WELDING MACHINE MODEL :- DK400H POWER SUPPLY :- 415V 3 phase, Earth, A.C./50Hz with 1% tolerance, Stabilized /30A. Power consumption :- estimated 20A peak AIR PRUSSURE - 7 Kg /sq.cm , constant ,dry & free from dust particles 6-8 Kg Important factors – 1. The welding results and consistency largely depends on quality of parts to weld like Warpage control, Dimensions and injection molding quality. 2. Melting temperature for heater plate expected 270-300ºC ± 10%. Please let us have your material data on this. 3. Machine Operation Sequence • Operator Puts Machine ON to achieve Temperature set –Make ON Vacuum. • Operator put an assembled plastic part into upper and lower fixture. • Activate lower part support bracket holding. • Operator press start button–—parts held in fixtures/jig. • Auto cycle starts if temperature achieved – Both Fixture/jigs close together to match and get apart (this can by pass) in auto cycle ---Heater Plate comes forward—Upper jig (descent)and lower jigs (ascent) with parts moves toward hot plate – Gets pressed against heater plate – heating time – Material soften time --- Fixtures get apart to some distance --- Heater plate moves backward – Both Fixtures close together to join parts – Hold time (cooling time) – Time end – Vacuum for upper part released – Both jigs goes to Origin – Welded part remain in lower jig – Operator open bracket holding and un load part from lower fixture – cycle complete– New parts loaded by operator. • Cycle program can be changed by suggestions, the one mentioned is better practice. • Suggestions in features of machine will be considered . certain specification of machine may change to suit to weld part of different height. 4. Cycle Time sequence estimate • Machine Set ON - 25 min. to achieve temp. (first time ) • Operator put parts into fixture and press start button (8-10S) • Heater plate comes forward and jigs close to it (3S) • Melting + soak time Expected (depends on weld rib design) (8S) • Jigs apart and Heater plate moves backward (3S) • Holding time for cooling, Includes jig close in (20-30S) • Both jigs retract back part remains in lower jig (2S) • Operator unload part (3S) • Cycle time depends on weld parameters, speed set, Weld line Dimensions so may vary and can set up on trials. • Estimate Cycle time : 45-57S • Based on above – Production per hour – 50 pcs.max. • Based on above – Production for 8 hrs run – 400pcs max. 5.
