Fully automatic HF welding machine for heat exchangers

Posted on: October 15th, 2014 by PixCompany No Comments

For a manufacturer of climate systems, we built and developed a special HF welding machine for the fully automatic assembling and welding of air heat exchangers. These air heat exchangers consist of a large number of pre-formed thin plastic sheets in right and left hand versions, which fully automatically alternate one by one, and sheet for sheet are welded onto each other. The machine contains:

  • a high frequency generator;
  • a double press for simultaneous assembling and welding of 2 air heat exchangers;
  • a 2-station turntable system for simultaneous feeding and positioning of plastic sheets during the welding cycle;
  • Pick & place systems for the feeding the various sheets during the welding cycle;
  • Supply buffers

For a Swiss relation, manufacturer of transparent plastic packaging, we developed and built a special HF forming machine for the fully automatic application of fold lines in flat plastic sheets, which can be folded to transparent packaging. The machine contains:

  • A high frequency generator;
  • Press with a sliding table system;
  • De-stacker and stacker;
  • Double pick & place system.

HF production line for filter bags

Posted on: October 15th, 2014 by PixCompany No Comments

We built this HF production line for the Slovak plant of a European air filter manufacturer. Using this HF production line, fully automatic pocket filters of varying compositions, filter materials and dimensions are produced: different filter material layers are automatically merged and welded together, with assembly edges and ribs, custom die cut stripped of any die-cutting waste. The HF production line consists of:

  • a take-up system for 5 different filter materials;
  • a bonding unit;
  • a high frequency generator;
  • a hydraulic HF press;
  • 3 pick & place systems for synchronous transit transport of the filter materials;
  • a hydraulic punch;
  • a waste separation system.

Fully automatic HF welding assembly line for bellows

Posted on: November 15th, 2015 by Wiljan Willems No Comments

For a German producer of ventilation systems, among other things, we have built a fully automatic HF welding assembly line for bellows, needed for air flow control in ventilation systems.

With the help of this HF welding assembly line, fully automatic thermoplastic bellows of varying size are welded and assembled.  The bellows are assembled and welded from several layers of foil, equipped with assembly holes and valves. The HF welding assembly line consists of:

  • a take-up system for two-layer foil bellows;
  • a dye-cutting system for mounting holes;
  • a vibratory filler, pick & place system and assembly unit for valve mounting;
  • a high frequency generator;
  • a pneumatic HF press;
  • 2 pick & place systems for synchronous transit transport of the bellow foils;
  • A waste separation system.

For a manufacturer of tarpaulins for trailers and trucks, we developed a fully automatic HF welding line for trailer tarpaulins. This HF welding line consists of:

  • 5 solid state HF generators;
  • 5 adjustable pneumatic presses with a pick & place system for welding mounting boxes;
  • 2 pick & place systems for synchronous transit transport of the trailer tarpaulins;
