5 HP IMS Staggered Blade Granulator | Model LP-88-SC | 1966 | S/N LP86SC0966

5 HP IMS Staggered Blade Granulator | Model LP-88-SC | 1966

The IMS LP-88-SC is a rugged "beside-the-press" granulator designed for the immediate reclamation of plastic sprues, runners, and scrap. This unit features IMS’s signature staggered helical blade technology, which uses a scissor-like cutting action to slice through plastic. This design significantly reduces noise, eliminates material "fly-back" in the hopper, and produces a uniform, high-quality regrind with minimal dust.

Manufactured in September 1966 (S/N LP86SC0966), this machine represents the classic era of American industrial manufacturing. Built with a heavy-cast frame and a reliable 5 HP drive motor, it is engineered for continuous 24/7 service. Its compact footprint and integrated casters make it ideal for localized recycling directly at the injection molding machine.

Key Features

• Staggered Cut Rotor: The helical blade arrangement ensures only one knife is cutting at any given time, reducing peak torque requirements and motor stress.
• Low-Noise Operation: The scissor-action cut is inherently quieter than straight-blade rotors, making it a better fit for operators working in close proximity.
• Easy Access Chamber: The hopper typically tilts back to allow for rapid, tool-free access to the screen and cutting chamber for material changes.
• Vintage Durability: Heavy-cast construction from the 1960s provides superior mass for absorbing vibrations, leading to a longer machine life and quieter operation.
