Shuttle or Swing Arm Machine |
The shuttle or swing arm machine is actually a type of highly aerodynamic single arm turret machine that displaces the mold back  and forth between the heating and cooling chambers in a linear direction. These avant-garde machines are generally equipped withenvironment friendly burners, which are suitable for LPG, CNG, OIL duel fuels. This independent indexing machine is highly preferred because of the fact that it is low in cost as compared to the the size of product it produces.
Shuttle machines are fast and efficient and also the stations are located far from each other. The heat panels of these machines are outfitted with advance heat transfer technology which facilitate an uniform heating that results in smooth, seam less end products with well defined outlines.
The process
The swing arm machine is generally used for manufacturing large/small hollow plastic articles. The most commonly used raw materials are High density polyethylene (HDPE ) and Low density polyethylene (LDPE). After the powdered polymers are poured into the molds, they are heated and rotated bi-axially by the arms, which are fixed to very powerful motors. this makes the powder inside the mold to melt and evenly distributed on the inner walls of the molds. After the molten material is evenly distributed, the mold is allowed to cool to let the thermoplastic solidify. As the material solidifies, it shrinks thereby de-attach itself from the inner walls of the mold.
A Shuttle or Swing Arm Machine is composed of :
- Molding Chamber (Indexing) with attached combustion chamber.
- High Velocity cooling fans with Fog heads.
- Arms conveyors.
- Control Electric Panel.
 Salient features of the Shuttle or Swing Arm Machine :
- Specially designed for the energy saving, environment friendly heating chambers with efficient heat transfer technology.
- State of the art technology in designing the insulation panels for better working environment.
- Straight-arm with four mold carrying carrier plates for economical working.
- Machine controls are equipped with necessary interlocking, safety devices with indicators and alarm.
- Micro-process based machine control panel with digital display.
- Variable speed a/c motors are for major and minor speed controls.
- Mold indexing facility.
- Environment friendly burners suitable for LPG/CNG/OIL/Duel fuels.
