Roller screw aids injection moulding
Satellite roller screw product produces the linear forces needed for injection, but has the advantage of being coupled to less expensive and more adjustable closed loop electric motor drive designs.
Traditionally, hydraulic cylinders initiate the pressure control required within injection moulding machines to ensure mould integrity Pneumatic systems can not produce the necessary forces and traditional ball screw designs would have to be oversized to achieve similar forces reliably

Roller screws beat ball screw performance
A new range of satellite roller screws from Abssac are high-precision linear devices that transform rotary movement into a linear movement.
Roller screws transmit more load
Abssac reckons its new programme of satellite roller screws is a formidable product range.
During injection moulding, plastic material is heated until molten.
A motorised auger screw forces the molten material to the end of the injection cylinder.
Once enough material has accumulated in front of the screw, the injection process begins with injection pressure provided by hydraulic actuation.
However, using hydraulics inevitably requires the use of hydraulic pumps, pipes, seals and control units within the machine, all of which can be bulky in design and expensive to maintain.
The satellite roller screw product, available from Abssac, produces the same linear forces necessary for injection, but has the advantage of being coupled to less expensive and more adjustable closed loop electric motor drive designs.
Satellite roller screws are particularly suitable for applications where high axial loads, high speed and high feed speeds are requested.
The design of the product transforms rotary movement into a linear movement via threaded rollers which ensure increased contacts points between the nut and screw enabling heavier axial loads and more longevity to any linear application.
Roller screws also reduce the space that is necessary for hydraulic actuation and can offer a fully traceable performance. Request a free brochure from Abssac ...
